Willi Fuehles, Germany - 22 February 2010: "2010 Shortwave Frequency Guide ... Ich war viel im Ausland und habe jetzt als Rentner wieder Zeit zum Radiohören. Bei den beiden anderen da hat die Qualität doch stark nachgelassen, haben die keine Fachleute mehr oder sind die alle schon gestorben? Ihre Bücher waren schon immer sehr genau, die konnte man noch nach Jahren in die Hand nehmen und verwenden."
Thieu Mandos NL199, NL-Post editor of VERON, in Electron, Netherlands - February 2010: "2009/2010 Guide to Utility Radio Stations ... standaardwerk voor de utility luisteraar. Een onvoorstelbare hoeveelheid details van de radiostations die je kunt beluisteren is te vinden in dit boek. Stations die werkelijk van over de geheles wereld komen. Interessant zijn ook de screenshots die het decoderen van diverse stations tonen, leuk te zien dat daar gebruikgemaakt wordt van de Perseus SDR-ontvanger en van WAVECOM decoders. Voor uitleg en de achtergrondinformatie moet je wel het boek erbij hebben. - 2010 Shortwave Frequency Guide ... Hiermee zijn de stations goed te identificeren of kun je op jacht gaan naar een van de stations. - 2010 Super Frequency List on CD ... voor wie echt alles wil weten van de kortegolf.

Anker Petersen, Chairman of Danish Shortwave Clubs International, in Shortwave News - January/February 2010: "2010 Shortwave Frequency Guide ... a comprehensive shortwave frequency list which for each frequency contains a line for each broadcast, practicably arranged in time order within each frequency. That includes exact times, transmitter site, language and target area. I prefer the Shortwave Frequency Guide when I scan the shortwave broadcast bands. In mid-December 2009 I listened to 50 broadcast stations at random in frequency band and time and identified them 100 %, no matter what language, and made a comparative analysis. WRTH 95 % correct, 2010 Shortwave Frequency Guide 96 % correct. - 2010 Super Frequency List on CD: This modern tool is very easy to use on a PC using Microsoft Windows and has excellent search functions for specific frequencies, countries, stations, languages, call signs and times - or any combination thereof!"
Mike Richards G4WNC, Decode editor of Radio User, United Kingdom - January 2010: "2009/2010 Guide to Utility Radio Stations ... time to turn to your trusty frequency guide. I use Klingenfuss as my main reference for two reasons - it's regularly updated and it allows you to look up utilities in several different ways."
H. van Heteren PE2VHE, Netherlands - 15 December 2009: "... many, many thanks for making a frequency database for the Perseus SDR!"
Alfredo Gallerati IK7JGI in Associazione Radioamatori Italiani's Radio Rivista, Italy - December 2009: "2010 Shortwave Frequency Guide ...

Paolo Valfrè I1VPJ, Italy - 7 April and 5 March 2009: "Klingenfuss frequency database for the MICROTELECOM Perseus LF-HF Software-Defined Receiver ... Ciao Giorgio, è arrivato ieri il CD, tutto OK, magnifico ... è molto comodo veder apparire i dati delle stazioni utility man mano che sposti la barra di sintonia! Adesso bisogna convincere Nico che introduca nel software di Perseus il passo da 3 kHz con la rotellina del mouse ... È favoloso Perseus unito alle tue liste!!!"
Bob Grove W8JHD, Chief Editor, in Monitoring Times, United States of America - March 2009: "2009/2010 Guide to Utility Radio Stations ... The shortwave spectrum continues to be home to a myriad signals, both voice and data, communicating globally. Trying to identify these stations can be a challenge, but with an accurate, up-to-date directory, the task is much easier. Joerg Klingenfuss’ Guide to Utility Radio Stations has become the standard source on monitoring the first 30 MHz of the radio spectrum. Information-packed chapters on digital data transmissions, along with hundreds of screen shots of decoded transmissions, assist the monitor in nailing down the sources of digital transmissions. Every serious shortwave listener should treat himself to this essential consummate reference. - 2009 Shortwave Frequency Guide ... Frequency information, as well as parallel frequencies, appear to be as accurate as possible considering seasonal frequency adjustments. As with other hobby publications, the Shortwave Frequency Guide uses a respected staff of leading radio contributors, providing the latest in information on the broadcast scene. The Klingenfuss Shortwave Guide remains a favorite reference in my listening post. The book layout for quick information access is easy to use. Whether monitoring a utility or broadcast station, this basic, no frills method of radio reference remains an asset to every listener. - 2009 Super Frequency List on CD ... Now in its 15th annual edition, this CD is the quintessential standard of reference for shortwave listeners. It is a massive, accurate composite of clandestine, utility and broadcasting stations listed in frequency order, which the listener can browse and search with key words. If you want instant information on stations heard in the 3-30 MHz spectrum, this CD is for you!"
Mike Richards G4WNC, Decode editor of Radio User, United Kingdom - March 2009: "2009/2010 Guide to Utility Radio Stations ... Klingenfuss has considerable experience and that shows in the latest release. This annually updated guide is an amazing piece of work, not only for the breadth of its content but also because Joerg uses monitoring stations all over the world to capture and validate the content. One of the points that make the Klingenfuss list unique is the constant worldwide monitoring. - 2009 Super Frequency List on CD ... includes some excellent and very fast search routines. The search engine searches as you type so you will generally find the result waiting for you as soon as you finish typing!"
B W Burt MM0GLX, Station Manager, Radio Monitoring Station, Greenock, Scotland, United Kingdom - 15 February 2009: "2009/2010 Guide to Utility Radio Stations ... 2009 Shortwave Frequency Guide ... 2009 Super Frequency List on CD ... Again we are impressed with the accuracy and scope of the Klingenfuss Radio Monitoring Publications. We have long been a user of your books which are used as a reference data base for our reception of unknown signals. This has over the years saved us hours of work. Keep up the good work."
Nils Schiffhauer DK8OK, Radio Editor, Germany - 13 January 2009: "Klingenfuss frequency database for the MICROTELECOM Perseus LF-HF Software-Defined Receiver ... Renowned DXer Joerg Klingenfuss, editor of his Guides to Utility Radio Stations (recognized as 'Gold Standard', now in its 25th volume), has stripped and converted his list of utility stations to fit Perseus' userlist.txt format. This works, as I just tried out, and is indispensable for utility DXers."
Nils Schiffhauer DK8OK, Radio Editor, Germany, in Perseus Tagebuch Dritter Teil - 13 January 2009: "Klingenfuss frequency database for the MICROTELECOM Perseus LF-HF Software-Defined Receiver ... Jörg Klingenfuss hat nun den Frequenzlistenbestand seines 'Guide to Utility Radio Station' so eingerichtet, dass er unter 'user' im entsprechenden Memory-Fenster des Perseus passend auftaucht. Funktioniert klasse und ist für Utility-DXer eine echte Hilfe!"
Anker Petersen, Chairman of Danish Shortwave Clubs International, in Shortwave News - February 2009: "2009 Shortwave Frequency Guide ... the current schedule and language is available at each frequency in time order. - 2009 Super Frequency List on CD: This modern tool is very easy to use on a PC using Microsoft Windows and has excellent search functions for specific frequencies, countries, stations, languages, call signs and times - or any combination thereof!"
Harald Kuhl, Buchbesprechungen editor of Radio-Kurier Weltweit Hören, Germany - January 2009: "2009/2010 Guide to Utility Radio Stations ... Der Autor hat sich schon früh mit der systematischen Beobachtung digitaler Übertragungsverfahren im Kurzwellenbereich befasst und ist auf diesem Gebiet ein weltweit bei Amateuren sowie Profis anerkannter Spezialist. Bildschirmfotos dekodierter Funksprüche aus aller Welt erlauben einen Blick in die sonst oft verschlossene Welt der professionellen Funkdienste auf Kurzwelle."
Nils Schiffhauer DK8OK, Radio Editor, Germany, in Radio-Kurier Weltweit Hören - January 2009: "WAVECOM W-CODE ... Die Top-Lösung. Der Code-Knacker der Profis. Besonders spannend sind die phasenmodulierten Signale, hier wiederum das aus der Militärtechnik übernommene Software-Konzept der STANAG-Modems mit ihren Varianten, die viele primär auf den Hobbymarkt fokussierenden Dekoder vor unlösbare Aufgaben stellen. Wo die Fähigkeiten dieser Dekoder wegfaden, übernimmt WAVECOM: die Kombination Perseus/WAVECOM bringt dem Ohr unhörbare STANAG-Signale selbst noch aus Neukaledonien auf den Bildschirm. Die Zusammenarbeit mit einem Software-Defined Radio wie dem PERSEUS ist besonders instruktiv und wegen der digitalen Weitergabe ohne mehrfache Konvertierung hocheffizient. W-CODE erweitert Ohren und Augen des Kurzwellenhörers um absolut professionelle Dekodier- und Analyseinstrumente und damit durch viele neue faszinierende Empfänge. Die Software definiert die oberste Leistungsklasse."
Wolfgang Steuhl in Straubinger Tagblatt - Landshuter Zeitung, Germany - 24 December 2008: "Jahrbuch Sender + Frequenzen ... World Radio TV Handbook ... Passport to World Band Radio ... Shortwave Frequency Guide ... Klingenfuß überzeugt nicht nur damit, dass er die zwischen den offiziellen Rundfunkbändern gelegenen Funkdienste berücksichtigt, sondern auch mit seiner Aktualität sowie mit seiner fast ans Unglaubliche grenzenden Präzision und Zuverlässigkeit, was die Frequenzlisten betrifft. Ja, was tun? Der Verfasser dieser Zeilen würde wohl den Klingenfuß nehmen, will aber die anderen auf gar keinen Fall herabsetzen. Hauptsache, es nützt!"
Raoul Maujean, Mauritius - 21 December 2008: "2009/2010 Guide to Utility Stations ... 2009 Shortwave Frequency Guide ... 2009 Super Frequency CD ... thanks for all those instructive and interesting documentations."
Dr.-Ing. Werner Hegewald DL2RD, Chief Editor of Funkamateur, Germany - January 2009: "2009/2010 Guide to Utility Radio Stations ... Der Autor hat sich schon früh mit der systematischen Beobachtung digitaler Übertragungsverfahren im HF-Bereich befasst und ist auf diesem Gebiet ein weltweit bei Amateuren sowie Profis anerkannter Spezialist. Ein üppiger Katalog mit Bildschirmfotos dekodierter digitaler Kurzwellenübertragungen aus aller Welt erlaubt interessante Einblicke in den digitalen Profifunk."
Hartmut Brodien in funkempfang.de , Germany - January/February 2009: "2009/2010 Guide to Utility Radio Stations ... 2009 Shortwave Frequency Guide ... 2009 Super Frequency List on CD ... Ein weltweites Netz erfahrener Mitarbeiter arbeitet mit modernsten Geräten und führenden Technologien an den Grundlagen für eine Erarbeitung der Frequenzlisten und anderer spezieller Angaben. Wer einen Blick auf die Internetseite der Firma wirft, kann einen Teil der Gründlichkeit erkennen. Kaum anderswo sind so viele Bildschirmfotos aus der Empfangspraxis zu finden wie hier."
Michiel Schaay, Netherlands, 14 December 2008: "2009 Shortwave Frequency Guide ... 2009 Super Frequency List on CD ... the results of your excellent monitoring efforts and admirable persistance."
Christoph Ratzer OE2CRM, Austria - 10 December 2008: "Heute kam hier ein dickes Paket aus Tübingen an: das aktuelle Kurzwellen-Frequenz-Handbuch 2009, die 13. Ausgabe. Redaktionsschluss 20. (!) November 2008 und schon am Stationstisch. Von den Berufskollegen WRTH und S+F 2009 noch weit und breit nichts zu sehen. Das Kurzwellen-Frequenz-Handbuch ist kein Ersatz für die beiden genannten, sondern DIE erstklassige Referenz, wenn es um Frequenzbelegungen sowohl im Broadcast- wie im Utility-Bereich geht. So kompakt und übersichtlich bietet nur Klingenfuß seine Listen an. Nicht billig, aber preiswert, wenn man den Aufwand und die Aktualität sieht. Mehr von mir, wenn ich die 446 Seiten durch habe. Begeisterte Grüsse, Christoph."
Daniele Cristaldini, Italy - 9 December 2008: "2009/2010 Guide to Utility Radio Stations ... 2009 Shortwave Frequency Guide ... Non vedo l'ora di ricevere i nuovi libri!"
Anker Petersen, Chairman of Danish Shortwave Clubs International, Denmark - 5 December 2008: "2009 Shortwave Frequency Guide and 2009 Super Frequency List on CD ... After a very quick glance, I see that it has the usual high standard. Just a quick check on 3960: VOIRI via Sitkunai 1430-1530 in Russian, R Racja via Sitkunai 1530-1730 in Belarusian. Well done for this spot check!"
Christoph Preutenborbeck, Germany - 1 December 2008: "... danke ich Ihnen für die ausgezeichnete Lieferung der wie immer vorzüglichen 2009 Super Frequency List on CD, die absolut korrekt ist, so macht das Hören Freude."
Nils Schiffhauer DK8OK, Radio Editor, Germany, in Frankfurter Allgemeine Zeitung - 18 November 2008: "WAVECOM W-CODE ... macht selbst einen Laptop zur leistungsstarken Abhörzentrale. Gegenüber billigen oder gar kostenlosen Dekodern aus der und für die Hobbyszene bietet nur das Profipack eine verlässliche Erkennung schwer auseinanderzuhaltender Signale und in jeder Disziplin jenes Mehr an Qualität, das in der Summe zu einer sicheren Mitschrift selbst stark gestörter und mit unbewaffnetem Ohr nicht mehr hörbarer Sender führt."
Claudio Di Bona, United Kingdom - 23 October 2008: "Guide to Utility Radio Stations ... Ti ammiro tantissimo sin dal 1993 guando comprai la mia prima radio in HF! Complimenti per il tuo italiano! Il tuo libro per me e come 'la bibbia del radioascolto', mai un errore, sempre informazioni corrette. Ma come fai? Sei il punto di riferimento a livello mondiale. Continua così!"
Bob Grove W8JHD, Chief Editor, in Monitoring Times, United States of America - August 2008: "I have had the opportunity over the last 30 years to observe first hand the changes that have taken place in the HF spectrum. You will notice that the HF radio spectrum of yesterday looks nothing like the HF spectrum of today. Nowhere is this more dramatically demonstrated than in the digital modes used on HF frequencies. While some old-timers claim the bands are dead and shortwave is being abandoned, nothing could be further from the truth. The bands are as active as ever, but the modes and services transmitting on HF have changed. It's the listening hobby that, for the most part, has not kept up with the times. If you want to get on board this changing world of HF digital communications, one publication stands out above all the rest - the Klingenfuss Radio Data Code Manual. Now in its 18th edition, Joerg Klingenfuss has literally compiled an encyclopedia of digital information for the HF radio spectrum in this voluminous publication. This standard international reference book is indispensable for identifying HF radio stations using various digital modes. If you plan on really listening to the HF digital spectrum of today, then you need this book on your reference shelf."
Randy Wynn, United States of America - 1 July 2008: "I really enjoy looking through the 2008 Guide to Utility Radio Stations and also the 2008 Shortwave Radio Guide. Both books are very informative."
Mike Richards G4WNC, Decode editor of Radio User, United Kingdom - July 2008: "The Radio Data Code Manual is one of the most important references for the serious utility listener simply because it brings together a vast amount of technical information that's not available in any other single publication. The manual has been written by enthusiasts and is widely used by both professional and hobby users around the world. I particularly like the baud rate tables in the section covering identification of digital data systems. Using the signal's baud rate along with these tables, you can narrow down the possibilities for an unknown signal very quickly. This is almost always faster than automated mode recognition software. To further help identification, the digital section includes lots of high quality screenshots from the WAVECOM W61 digital data decoder. The Radio Data Code Manual continues to be the prime reference for those interested in monitoring a wide range of radio transmissions. The content is bang up to date and the range of information is not available in any other single publication."
Harald Kuhl, Buchbesprechungen editor of Radio-Kurier Weltweit Hören, Germany - June 2008: "Konkurrenzlose Eigenschaften der Kurzwelle ... Heute belegen moderne Fernschreibverfahren in einer erstaunlichen Vielfalt die Frequenzen. Radio Data Code Manual ... spart dem interessierten Datenfunker die mühsame und in einigen Fällen schwierige Sucher nach anderen Informationsquellen. Das empfehlenswerte Buch hat sich bei professionellen Anwendern als Standardwerk etabliert."
Funkamateur, Germany - June 2008: "Digitale Verfahren dominieren heute weltweit den professionellen Funkverkehr auf Kurzwelle. Funkdienstspezialist Jörg Klingenfuss' Radio Data Code Manual erlaubt einen Blick auf die oft verschlossene Welt der professionellen Übertragungsverfahren."
Megahertz, France - May 2008: "Radio Data Code Manual ... L'ouvrage fait office de référence dans le milieu et il est consideré comme indispensable pour identifier un grand nombre de modes 'exotiques' que l'on peut entendre sur les bandes HF."
Randy R Wynn, United States of America - 28 April 2008: "The 2007/2008 Guide to Utility Radio Stations is very well put together, and very informative, and can't wait to get next year's edition. The books are very helpful here stateside."
Harald Kuhl, Buchbesprechungen editor of Radio-Kurier Weltweit Hören, Germany - April 2008: "2008 Shortwave Frequency Guide ... 2007/2008 Guide to Utility Radio Stations ... 2008 Super Frequency List on CD ... Die Frequenzlisten aus dem Klingenfuss Verlag genießen nicht grundlos weltweit bei Kurzwellenhörern einen hervorragenden Ruf und die hier vorgestellten Ausgaben bestätigen das gewachsene Vertrauen."
Daniele Taliani IV3TDM in Associazione Radioamatori Italiani's Radio Rivista, Italy - March 2008: "L'attività di Joerg, iniziata nel 1970, con i suoi 39 anni di esperienza può senz'altro essere collocata al vertice, sia per la mole di dati che per l'assoluta affidabilità di quanto riportato.Se è vero che le frequenze, come le donne, sono variabili 'come piume al vento', è altrettanto vero che quelle indicate da Klingenfuss sono quanto di più aggiornato l'attuale bibliografia metta a disposizione. 2007/2008 Guide to Utility Radio Stations ... Quando tanti anni addietro mi ci dedicavo anch'io (stante il fatto che non ero nelle condizioni di antenna tali da poter trasmettere), mi sono trovato a sentire la necessità di una guida che mi facilitasse il compito di ricerca e devo dire che fin da quei tempi (parlo dell'inizio anni 80), ho trovato in Klingenfuss un preciso riferimento, pieno di dati tecnici, di consigli e di 'trucchetti' che mi hanno portato ad appassionarmi sempre più, contrariamente ad alcuni amici che dopo numerosi quanto infruttuosi tentativi 'fai da te', hanno preferito dedicarsi ad altro. 2008 Super Frequency List on CD ... Lo stesso CD, oltre a numerosissime informazioni tutte volte ad ampliare la cultura dell'SWL, propone anche una serie di alcune centinaia di screenshot utili a dare immediatamente l'idea di cosa si possa ascoltare ancora oggi, nel meraviglioso ed infinito spazio delle onde corte. Radio Data Code Manual ... Un manuale divenuto ormai standard di riferimento internazionale sia per l'SWL che per i servizi di radio monitoring professionali. Chi volesse avventurarsi in questo fantastico mondo, potrà trovare in Klingenfuss una vera miniera di informazioni ed un prezioso alleato, con una esperienza che si colloca certamente ai vertici a livello mondiale e che non disdegnerà di fornire tutte le informazioni utili ad ognuno per cominciare col piede giusto o per proseguire con sicurezza."
Gayle and Larry van Horn, Assistant Editors, in Monitoring Times, United States of America - March 2008: "The 2008 Klingenfuss Shortwave Guide remains a favorite reference aid in the Van Horn DX Cabin. The modern layout for quick information access is easy to use. Whether monitoring a utility or broadcast station, this basic, no frills method of radio reference remains an asset to every listener. - For the serious shortwave utility hunter or broadcast listener, the 2008 Super Frequency List on CD is the ultimate disk database."
Antonio Sorrentino I8SWZ, Italy - 22 March 2008: "Klingenfuss Publications e Klingenfuss Radio Monitoring possono essere considerati come l'enciclopedia del radioascolto realizzata da Joerg Klingenfuss che in circa 40 anni ha messo insieme e catalogato un'enorme mole di dati utili e nello stesso tempo affidabili e sempre aggiornati."
Radio User, United Kingdom - February 2008: "For those with a general interest in short wave listening, the 2008 Shortwave Frequency Guide is a must-have reference book. It's about as up-to-date as you can get ... providing an excellent combination of broadcast and utility information in a single volume."
Hans K Hildebrand WA1UFO, United States of America - 10 February 2008: "Guide to Utility Radio Stations ... Your radio guides are awesome!"
Anker Petersen, Chairman of Danish Shortwave Clubs International, in Shortwave News - February 2008: "I prefer the 2008 Shortwave Frequency Guide when I scan the shortwave broadcast bands, because the current schedule and language is available at each frequency. - Comparison: I counted how many essential details were correct for the 25 international and 25 domestic stations randomly heard. The results were Passport to World Band Radio 92 percent, 2008 Shortwave Frequency Guide 97 percent, and World Radio TV Handbook 96 percent. The 2008 Shortwave Frequency Guide is slightly better, because the domestic stations of All India Radio contain the three main languages."
Radio User, United Kingdom - January 2008: "The Klingenfuss 2007/2008 Guide to Utility Radio Stations has remained a best seller for the past 25 years and is an excellent reference publication for the utility enthusiast. There is no other source that compiles such as comprehensive range of information into a single publication. This is all vital data that can save the enthusiast hours of investigation. - The 2008 Shortwave Frequency Guide is a must-have reference book. It's about as up-to-date as you can get. - The 2008 Super Frequency List on CD comes with its own built-in search engine that is remarkably quick and searches on each letter of the search word as you type it. As a result, the answer is usually displayed before you've finished typing!"
Mike Richards G4WNC, Decode editor of Radio User, United Kingdom - December 2007: "... the best known source of printed schedules is the Klingenfuss Guide to Utility Radio Stations. This excellent reference is updated annually and provides one of the best references available to the enthusiast. In addition to the book's detailed coverage of the HF bands, there is a section dedicated to weather fax with frequencies, callsigns and schedules for stations throughout the world."
Christoph Preutenborbeck, Germany - 13 December 2007: "2008 Super Frequency List on CD ... Vorzügliche Lieferung. Vorzügliche CD."
Andrea Lawendel, Italy - 11 December 2007: "L'esperto tedesco è una autorità internazionale in materia e da anni sostiene che la radio è un mezzo tutt'altro che obsoleto quando si tratta di comunicazioni civili e militari in situazioni estreme o di emergenza."
Hidetoshi Okano, Japan - 5 December 2007: "2007/2008 Guide to Utility Radio Stations ... 2008 Super Frequency List on CD ... 2008 Shortwave Frequency Guide ... Thank you for your wonderful publications. I am satisfied with these ones."
Ken Baird, New Zealand - 13 November 2007: "Shortwave Frequency Guide ... I find it a most useful book to have and appreciate the enormous amount of work that goes into it's preparation."
Mike Richards G4WNC, Decode editor of Radio User, United Kingdom - July 2007: "... the famous Guide to Utility Radio Stations. Joerg Klingenfuss and his contributors go to great lengths to capture as many stations as possible from all over the world. In fact, they deliberately go to out-of-way listening locations so they can operate from noise-free locations to capture the maximum number of stations. The monitoring and capturing process is continuous, which is how they are able to produce such an up-to-date reference book. The Klingenfuss Guide has, rightfully, earned itself a place in the most advanced radio monitoring stations."
Wolfgang Hadel DK2OM, Digital Data Expert of the Intruder Watch of Deutscher Amateur Radio Club (DARC), in Funkamateur July 2007: "Der WAVECOM-Classifier erfaßt die Parameter des Systems in Sekundenschnelle. WAVECOM-Dekoder sind nicht billig, aber in dieser Preisklasse unschlagbar. Deshalb gehören sie zur Grundausrüstung vieler militärischer und ziviler Dienststellen. Mein alter Kaho-Dekoder hat ausgedient."
Henrik Thiil Nielsen, Denmark - 14 May 2007: "Klingenfuss's two double CDs of Modulation Types recordings are a little pricey but I have found them extremely useful. You can listen to them to get acquainted with the sound of different data modes, you can use them as input for your decoding software (or hardware) in order to test the decoder and improve your own decoding skills. Their advantage for these purposes over 'live' material is that modes and parameters are listed for each recording and the recordings are of high quality. - One of the best sources of information on what to listen to on which frequencies is the Klingenfuss Guide to Utility Radio Stations. - Indispensable reference: Radio Data Code Manual."
Sergio Mas Ruiz, Spain - 27 March 2007: "Felicitaciones por su aportaciòn al mundo de las radiocomunicaciones tanto profesionales como amateur, gracias!"

This fine collection for the utilities monitor leaves little to be desired."
Nils Schiffhauer ex DK8OK, ex editor of ex Funk, Germany, in Funktelegramm - March 2007: "Information fördert DX-Erfolge. Eine immer unverzichtbare Handreichung bietet Jörg Klingenfuß mit seinem 2007/2008 Guide to Utility Radio Stations, der seit Jahren vom Monitoring-Tisch nicht wegzudenken ist."

Pieter on UDXF, Netherlands - 20 January 2007: "Hi Glenn, let me tell U 1 thing, I was able to try the Wavecom W61LAN and the Code300-32 v3.0. The Wavecom was 80 percent better than the Kaho decoder. It's a lot of money. So, when you have some savings, go for the Wavecom: W61LAN Professional + all updates 9,600 USD."
Daniele Cristaldini, Italy - 16 January 2007: "2007/2008 Guide to Utility Radio Stations ... 2007 Super Frequency List on CD ... 2007 Shortwave Frequency Guide ... wonderful publications. Let me say that your job is superb!"

Radio User, United Kingdom - January 2007: "The Klingenfuss 2007/2008 Guide to Utility Radio Stations has remained a best seller for the past 25 years which is testament to this excellent reference publication.

Ausgezeichnete Fachartikel ... besonders ausführlich wird sich zukünftigen digitalen Übertragungsverfahren gewidmet ... in seiner Genauigkeit und Ausführlichkeit unerreicht. Es gibt in Papierform kein besseres und aktuelleres Nachschlagewerk für Kurzwellenhörer. Zusätzlich sind die Informationen des Buches auch auf CD erhältlich."
Ronald Edberg, United Kingdom - 4 January 2007: "I received my 2007 Super Frequency List on CD last week and it is very good."
Erik Køie, ex Danmarks Radio, Holte, Denmark - 24 December 2006: "2007/2008 Guide to Utility Radio Stations ... Again a very comprehensive book."
Paolo Valfré I1VPJ, Italy - 23 December 2006: "2007/2008 Guide to Utility Radio Stations ... 2007 Super Frequency List on CD ... Ancora complimenti per il suo lavoro e per i suoi prodotti, precisi ed impeccabili e completi anche di commenti puntuali e sagaci!"
Wolfgang Büschel DF5SX, Germany - 11 December 2006: "2007 Super Frequency List on CD ... 2007 Shortwave Frequency Guide ... Wie immer: sehr, sehr willkommen und eine prägende Landmarke im Ablauf des Jahres."
James D Strader, United States of America - 10 December 2006: "2007/2008 Guide to Utility Radio Stations ... 2007 Super Frequency List on CD ... 2007 Shortwave Frequency Guide ... 1997-2007 Digital Data Decoder Screenshots CD ... This is my favourite Christmas Gift to myself for over a decade. The accuracy and information contained in your publications is second to none!"
Anthony Farrugia, Malta - 9 December 2006: "2007/2008 Guide to Utility Radio Stations ... 2007 Super Frequency List on CD ... 2007 Shortwave Frequency Guide ... Keep up the good work! Your publications are the only ones which are really up to date and do not contain obsolete entries."
Hidetoshi Okano, Japan - 1 December 2006: "2007/2008 Guide to Utility Radio Stations ... 2007 Super Frequency List on CD ... 2007 Shortwave Frequency Guide ... Thank you for your wonderful publications. I am satisfied with these ones."
Steven Gardiner, United Kingdom - 5 November 2006: "2005/2006 Guide to Utility Radio Stations ... I use to get the book quite regularly here in the UK as it is the best book available in my opinion for date mode listeners like myself."
Mike Chace, Digital Digest editor of Monitoring Times, United States of America - October 2006: "Kaho vs. WAVECOM ... WAVECOM has better customer support, more modern gear, is generally quick to release new modes."
Mike Richards G4WNC, Decode editor of Radio User, United Kingdom - April 2006: "Radio Data Code Manual ... This remains the most comprehensive reference manual for data signals that is generally available. Whilst there are some excellent reference sources on the Internet, a single publication with such detailed information remains a powerful tool for the data enthusiast. The teleprinter alphabet section not only shows details of the various systems, but is set-out in tabular form so you can quickly spot the key features. For those interested in unknown signals, section 5 provides in-depth analysis of the operation of a wide range of modes and sub-modes. With the help of a few analysis tools and this excellent manual you should be able to classify unknown signals very efficiently."
Alfredo Gallerati IK7JGI in Associazione Radioamatori Italiani's Radio Rivista, Italy - April 2006: "Una guida molta aggiornata, sopratutto di facile consultazione, è la 2006 Shortwave Frequency Guide. Joerg Klingenfuss: 'Cosa c'è di meglio? Solo noi, e nessun altro, pubblichiamo tutti i dati anche in versione CD.' "
Defence Special Signals School, Bletchley Wing, Corporal Gary Hamilton, Chicksands, Bedfordshire, United Kingdom - 10 March 2006: "2005/2006 Guide to Utility Radio Stations ... Radio Data Code Manual ... Without the help of your literature over the past couple of months the course I have just completed would have been a lot more difficult."
Gayle and Larry van Horn, Assistant Editors of Monitoring Times, United States of America - March 2006: "2006 Super Frequency List on CD ... If you use a computer in your listening post, this is an extremely useful reference to have running while tuning the HF radio spectrum. We were particularly impressed with its ease of use, and its search and sort capability. Given the bright future of e-book publishing, it is nice to see Klingenfuss support both print and electronic formats for some of his more popular publications. The 2006 Shortwave Frequency Guide and the 2006 Super Frequency List on CD are two of our favorite annual reference publications that we use in our radio listening post. Regardless of what portion of the HF spectrum you prowl, these two publications will provide a lot of listening information at your fingertips. Either or both deserve a place next to your radio."
Mike Richards G4WNC, Decode editor of Radio User, United Kingdom - March 2006: "Radio Data Code Manual ... This is a wonderful reference book that contains a host of otherwise difficult to find information. If you are serious about finding and decoding some of the more advanced systems this manual is pretty much a necessity. Section 4 contains some excellent summaries of the various teleprinter alphabets that you are likely to encounter. These are compared side-by-side, so it's easy to spot and compare the different parameters. These tables are essential if you're attempting any bit analysis work. Section 5 is another gem with a detailed look at all the main systems that you will find on HF. As well as general descriptions of the modes, there are detailed charts explaining the inner workings of both the synchronisation and error correction routines. The illustrations are excellent and convey what is complex information in an easy to digest format. I've just covered the highlights here, but there's lots more information tucked away in this excellent publication."
Uli Bihlmayer DJ9KR, President of the Monitoring Service of Deutscher Amateur-Radio-Club, in cq-DL, Germany - February 2006: "Durch den Einsatz modernster Nachrichtencomputer vor allem der Schweizer Firma WAVECOM ist die Bandwacht des DARC heutzutage führend, die verschiedenen Übertragungsmodi digitaler Aussendungen kommerzieller und militärischer Anwender zu bestimmen und teilweise auch zu entschlüsseln."
Megahertz, France - February 2006: "2006 Shortwave Frequency Guide ... Les ouvrages de Joerg Klingenfuss font partie de patrimoine du radio-écouteur."
Bud Peed, United States of America - 5 February 2006: "2005/2006 Guide to Utility Radio Stations ... Radio Data Code Manual ... Have been a great fan of your books for years. They are never discarded, only read over and over! Your books are spot on and a big help in my hobby! Well done."
Harald Kuhl, Buchbesprechungen editor of Radio-Kurier Weltweit Hören, Germany - February 2006: "2006 Shortwave Frequency Guide ... Mit Effizient und ohne Schnörkel präsentiert dieses Frequenzjahrbuch die bei Redaktionsschluß aktuellen Daten aktiver Kurzwellenstationen. In der Praxis am Empfänger ist diese Frequenzliste eine große Hilfe bei der Identifizierung von Stationen."
Anker Petersen, Chairman of Danish Shortwave Clubs International, in Shortwave News - 16 January 2006: "2006 Super Frequency List on CD ... total of 19,100 utility and broadcast entries on SW. This modern tool is very easy to use on a PC using Windows and has excellent search functions for specific frequencies, countries, stations, languages, call signs and times - or any combination thereof! 2006 Shortwave Frequency Guide ... I prefer it when I scan the shortwave broadcast bands, because the current schedule and language is available at each frequency. Very comprehensive, up-to-date and accurate and absolutely worth purchasing!"
Bob Padula, Australia, in Electronic DX Press - January 2006: "2006 Super Frequency List on CD ... Access time for retrieving the data is in milliseconds, and searches may also be made for specific frequencies, countries, abbreviations, languages, callsigns and times. 2006 Shortwave Frequency Guide ... Timely additional information is included about technological developments in HF broadcasting, including digital modulation, and an in-depth introduction to shortwave radio monitoring. Content based on actual monitoring by the author and a team of experts around the world."

Claus Dietrich, Germany - 21 December 2005: "Ich besitze die zwölfte Ausgabe des Radioteletype Code Manual und arbeite an einer Erweiterung meiner Fernschreib-(Message Handling-) Software Ticker für die Koreanische Marine. Ihr Buch stellt für meine Arbeit eine großartige Hilfe dar."
Mark T Egan VK2KLJ - 20 June 2005: "2005 Super Frequency List on CD ... Your database software is wonderful and the digital signal CD's great for identifying many signal types."
Anthony Farrugia, Malta - 4 June 2005: "2005/2006 Guide to Utility Radio Stations ... 2005 Shortwave Frequency Guide ... I found both publications up to date and very useful. No other publications provide so much competent information."
Massimo Petrantoni in Confidential Radio Secret 2 - I Misteri delle Etere, Italy, March 2005: "2005/2006 Guide to Utility Radio Stations ... una attività di monitoraggio professionale che viene condotta in maniera scientifica. Le stazioni elencate in tale famosa guida sono realmente esistenti ed effetivamente monitorate a differenza di pubblicazioni analoghe ove sono riportate frequenze inattive da tempo e obsolete. In realtà il sistema di gestione del log adottato da Joerg elimina automaticamente quelle frequenze che non risultino attive da 15 mesi, ragion per cui i dati che esso fornisce sono notevolmente aggiornati e veritieri ... la guida più valida e più scientifica per potere districarsi all'interno delle gamme HF. Sono riportate esclusivamente stazioni con codici realmente decodificabili e sincronizzabili con i decoder professionali WAVECOM."
Radio Society of Great Britain's Headquarters Staff in RadCom - March 2005: "2005 Shortwave Frequency Guide ... logical and uncluttered layout. It is likely that there will be a resurgence of interest in HF broadcast listening as more DRM broadcasts come on stream, with their promise of near-FM quality reception. The 2005 Shortwave Frequency Guide covers DRM well, with information on receivers and an up to date listing of those DRM broadcasts already available. For those who use their general-coverage receivers to stufy HF propagation, the 2005 Shortwave Frequency Guide will be a Godsend, reducing enormously the time and effort involved in identifying stations which, by the fact that by and large they use the same frequency at the same times each day, can be used as propagation 'beacons'. For those who want to tune in to specific stations, listen to broadcasts in a particular language, or simply wish to explore the shortwave bands in more details, the 2005 Shortwave Frequency Guide is a must."
Bob Margolis, Products and Books Review Editor, on www.wunclub.com - 1 February 2005: "2005/2006 Guide to Utility Radio Stations ... , I always compare it to the previous edition to see what updates have been made ... This shows the extent to which Klingenfuss Publications keeps on top in monitoring the airwaves. That is why the Klingenfuss utility guidebooks are worthy purchases year after year."
Funk, Germany - February 2005: "2005/2006 Guide to Utility Radio Stations ... Funkamateure und Hörfunkstationen nutzen nur einen kleinen Teil der Kurzwelle, der große Rest ist den kommerziellen Funkdiensten vorbehalten: Flugzeuge, Schiffe, Botschaften, Militär. Und die machen davon weiterhin regen Gebrauch, wie ein Blick ins Buch beweist. Der Autor ist Spezialist für den Empfang von Funkdienststationen mit dem Schwerpunkt auf den digitalen Betriebsarten."
Geoffrey V Stocks, United Kingdom - 18 January 2005: "2005 Shortwave Frequency Guide ... to say I am impressed is an understatement. I cannot boast of having fancy equipment just a love for tuning in around the world and your publication is so informative and easy to use."
Christoph Ratzer OE2CRM, Austria, January 2005: "Shortwave Frequency Guide ... Ausgezeichnete Fachartikel ... in seiner Genauigkeit und Ausführlichkeit unerreicht.

Jan Nieuwenhuis, Publications editor of Benelux DX Club Bulletin, Netherlands - January 2005: "2004 Shortwave Frequency Guide ... a comprehensive reference ... covers everything you need for serious short-wave listening. Once again a great source of information! - 2005/2006 Guide to Utility Radio Stations ... THE book for shortwave utility listening with an enormous account of accurate information. It's a must have book for the serious utility monitor. - 2005 Super Frequency List on CD ... ... a comprehensive reference dor the shortwave broadcast and utility monitor."
Megahertz, France - January 2005: "... diffusion des informations tres precises sur les sources d'emission ... Ces livres, que tout radio-ecouteur exigeant se doit de posseder, constituent une incontestable reference en la matiere et permettent d'identifier des modes de modulation que l'on ne connait et eventuellement, de les decoder si l'on possede le logiciel ou le materiel correspondants."
Anker Petersen, Chairman of Danish Shortwave Clubs International, in Shortwave News - January 2005: "I prefer the 2005 Shortwave Frequency Guide when I scan the shortwave broadcast bands, because the current schedule and language is added to the frequency list. Moreover, the 2005 Super Frequency List on CD is unsurpassed with its search capability on a PC: in a split-second you are able to get all entries in either frequency-, station-, country-, language- or time order which is extremely useful for the shortwave listener."
Francisco de las Casas, Spain - 7 January 2005: "2005/2006 Guide to Utility Radio Stations ... 2005 Super Frequency List on CD ... I've been using up to day the 2003 versions and it has been very useful to me. Carry on in this way. My congratulations for your publications."
Harald Kuhl, Buchbesprechungen editor of Radio-Kurier Weltweit Hören, Germany - January 2005: "2005 Super Frequency List on CD ... Die intelligente Lesesoftware erlaubt es, sich im Handumdrehen beliebige Sendepläne zusammenzustellen und auf den Bildschirm zu holen. Man ist nicht mehr auf das starr vorgegebene Format in Büchern festgelegt und kann sich zum Beispiel eine Liste aller derzeit in einer bestimmten Sprache laufenden Sendungen heraussuchen lassen. Vor allem wer während der Senderjagd den Computer ohnehin einsetzt, um vielleicht Ausbreitungsprognosen zu erstellen, den Empfänger zu steuern oder sich den Verlauf von Hell-Dunkel-Zonen darstellen zu lassen, wird auch auf die 'Klingenfuss-CD' bald nicht mehr verzichten wollen."
Mike Richards G4WNC, Decode editor of Shortwave Magazine, United Kingdom - January 2005: "If you are fortunate enough to have the 2005 Super Frequency List on CD there's a country search built-in. This, I've found, is probably the fastest and most efficient way to identify stations by country. If you have just the paper-based version of 2005/2006 Guide to Utility Radio Stations all is not lost as this includes a host of information designed to make life easy for the listener. One chapter that's often missed is the station list. If for example, you're looking for stations in Canada you will find all the stations listed in one place along with call signs and all the current operating frequencies - pretty impressive! This is much more efficient than trawling through a bare frequency list. It's this clever compilation of extensive utility information into a practical format that makes the Klingenfuss guide so valuable."
Vincent Plousey, France - 15 December 2004: "Je suis SWL depuis 1990 et j'utilise vos manuels Guide to Utility Radio Stations depuis 1993 et votre Radio Data Code Manual depuis 1998. Encore toute mes felicitations pour votre travail fabuleux!"
Josef Garcia, Germany - 15 December 2004: "Vielen Dank fuer die 2005 Super Frequency List on CD. Einfach FANTASTISCH!!!!!!!"
Sergio Mas Ruiz, Spain - 10 December 2004: "2005/2006 Guide to Utility Radio Stations ... 2005 Super Frequency List on CD ... Felicitaciones por sus interesantes publicaciones!!!"
James D Strader, United States of America - 7 December 2004: "2005/2006 Guide to Utility Radio Stations ... 2005 Super Frequency List on CD ... 2005 Shortwave Frequency Guide ... you are still 'NUMBER ONE' in accuracy and quality."
Aidan Nightingale, United Kingdom - 18 November 2004: "By far the best publication and most informative publication I've found is the Klingenfuss Radio Code Manual. Much of the information in this publication I've yet to see available on the Internet. It's a good primer for anybody interested in the concepts, protocols and modes of communication on the HF spectrum."
Josef Garcia, Germany - 17 September 2004: "2004 Super Frequency List on CD ... zu Ihrer tollen CD hatte ich ein schoenes Ahhhha-Erlebnis mitbekommen. Als ich vor einigen Monaten einen Hobby-Kollegen besuchte, suchte er in einem grossen Stapel Frequenzlisten den ALE-Call 'ADW'. Als er nach fieberhafter Suche entnervt aufgab, lud ich ihn zu mir nach Hause ein, und fuehrte Ihre CD vor. Er war ganz von den Socken, wie schnell ich die Station finden konnte. Er hat sofort eine CD bestellt."
Nils Schiffhauer in FAZ - 14 September 2004: "Schon wenige Watt Sendeleistung und eine unauffaellige Antenne reichen, um mit Computerunterstuetzung zuverlaessig digitale Verbindungen zwischen Kontinenten herzustellen. Nach einer Anfangsinvestition von wenigen 1000 Euro und bei Energiebedarf, der aus einer Solarbatterie gedeckt werden kann, sind keine weiteren Gebuehren zu entrichten. Die Kurzwelle ist kostenlos. Und sie ist bequem geworden. Wenn frueher ein Fachmann die je nach Tages- und Jahreszeit sowie zu ueberbrueckender Entfernung passenden Frequenzen muehevoll zu kalkulieren hatte, so uebernimmt heute Software diesen automatischen Verbindungsaufbau. ALE wie Automatic Link Establishment nennt man das. Eine zu Empfangsversuchen anregende Uebersicht bietet die Frequenzliste "2004 Guide to Utility Radio Stations" des Tuebinger Experten Joerg Klingenfuss mit ihren 1700 Stationen auf 10200 Frequenzen. Bei dieser Lektuere waechst der Appetit ueber die Leistungsfaehigkeit der SkySweep-Software hinaus, weil Delikatessen wie das Rote Kreuz im afghanischen Mazar-i-Sharif oder ein Al-Qaida-Sender auf 20597,3 Kilohertz aus dem pakistanischen Faisalabad nur mit teuren Hardware-Decodern wie dem W51PC des Schweizer Spezialisten WAVECOM mitzulesen sind."
Fabrizio Magrone, Italy on it.hobby.radioascolto - 4 September 2004: "Dal mio punto di vista, con diversi anni di ascolto alle spalle, la lista di prima scelta per chi deve acquistare il primo libro e la Klingenfuss, perche contiene numerose informazioni addizionali che non si trovano in altre liste."
Dr.-Ing. Werner Hegewald DL2RD, Chief Editor of Funkamateur, Germany - July 2004: "2004 Guide to Utility Radio Stations ... Digitale Funksignale haben auf Kurzwelle derart inflationär zugenommen, daß der gelegentliche Funkdienst-DXer schnell den Überblick verliert. Ordnung ins Sendegeschehen professioneller Kurzwellen-Funker bringt seit Jahren Jörg Klingenfuß. Zahlreiche Screenshots vermitteln einen Eindruck von der Leistung eines guten Dekoders."
Horst Garbe DK3GV in Radio-Scanner, Germany - June 2004: "Die gute alte Kurzwelle hat auch im Zeitalter der modernen Satellitenkommunikation noch lange nicht ausgedient. Fernschreib-und Datensignale zu empfangen ist nicht schwer. Entsprechende Dekoder in verschiedenen Preiskategorien oder entsprechende Computerprogramme machen es möglich. Und dann? Dann stehen meist unverständliche Dinge auf dem Bildschirm! Dass dies aber nicht unbedingt eine Textverschlüsselung sein muss, das verrät uns unter anderem das Radio Data Code Manual. Auf 600 Seiten (!) wird der ernsthaft Interessierte an Fernschreib- und Datenübertragungen in die Geheimnisse dieser äußerst interessanten Übertragungsarten eingeweiht. Dabei schafft es Jörg Klingenfuß, über das normale Maß hinaus 'Unmengen' Betriebsarten bis ins Detail zu beleuchten. Und das im wahrsten Sinne des Wortes, wird doch anhand zahlreicher 'Screenshots' gezeigt, wie ein Signal zunächst analysiert und dann dekodiert wird. Unter anderem werden Multiplexverfahren sowie ARQ- und FEC-Fehlerkorrektursysteme erklärt. Sogar die für Europäer so exotischen Zeichen arabischer oder chinesischer Schriftzeichen in der Fernschreibübertragung werden erschöpfend erklärt. Selbst erfahrene Fernschreib- und Datenfunker werden erstaunt sein, wie viele unterschiedliche Übertragungsverfahren es gibt. Weitere Kapitel widmen sich den Flugdatenfunkübertragungen sowie meteorologischen Aussendungen. Die gerade hier häufig verwendeten Buchstabenkodierungen werden ihres Geheimnisses beraubt. Endlich weiß der Empfänger, was das Buchstabengewirr auf seinem Monitor bedeutet und welche Station er empfangen hat! Besonders spannend wird es noch einmal zum Schluss des Buches, wenn der Autor sich den Verschlüsselungsverfahren der Geheimdienste widmet. Das Radio Data Code Manual ist ein faszinierendes Buch für eine ebenso faszinierendeVariante des Kurzwellen- und UKW-Empfangs. Es wendet sich eindeutig an den Spezialisten des Empfangs drahtloser Fernschreib-und Datenübertragungen. Gerade bei diesen Spezialisten darf dieses Buch nicht fehlen, will man auf genanntem Gebiet einen erfolgreichen Empfang ohne Enttäuschungen erleben."
Bob Grove W8JHD, Chief Editor, in Monitoring Times, United States of America - March 2004: "2004 Shortwave Frequency Guide ... as with previous editions, it's a gem. Broadcast listeners can instantly narrow down identification of any station among those transmitting on a frequency at a given time. This is a great aid and quick access during a DX session or for a program listener. The alphabetical list of broadcast stations is invaluable when focusing on a particular country to monitor."
Funk, Germany - March 2004: "Seit ihrer Einfuehrung vor zehn Jahren ist die Super-Frequenzliste von Klingenfuss die einzige CD-ROM geblieben, die die neuesten Sendplaene ... praesentiert."
Harold Ort N2RLL, Chief Editor of Popular Communications, United States of America - March 2004: "Monitors have come to know and trust the Klingenfuss 2004 Super Frequency List on CD. Among the digital data decoder screenshots are many stations of the International Committee of the Red Cross in the Afghanistan and Iraq war zones."
Angelo Brunero IK1QLD, CISI, Università di Torino, Italy - 18 June 2003: "Un paio di pubblicazioni che spesso consulto per sapere qualcosa in più sono Shortwave Frequency Guide (Worldwide HF Communications Today) e Guide to Utility Radio Stations di Joerg Klingenfuss."
Michiel Schaay at 3 April 2003 on www.kortegolf.info and in Radio Amateur Magazine, Netherlands, May 2003: "Radio Data Code Manual ... een werkelijk goed inzicht te verwerven in de digitale transmissiesoorten en –protocollen die de kortegolf bevolken. Gerichte zoekopdrachten op het internet kunnen veel interessante informatie boven water brengen. Toch blijft er altijd behoefte aan een gedrukt overzichtswerk. In zijn Radio Data Code Manual brengt Klingenfuss een grote hoeveelheid relevante informatie samen. Gewapend met dit 600 pagina's tellende boekwerk, kan de toegewijde hobbyist zich stap voor stap een weg banen in de (soms ondoorzichtige) wereld van de professionele kortegolf communicatie. Klingenfuss rafelt een aantal belangrijke digitale transmissietechnieken uiteen, ruimschoots geïllustreerd met signaalanalyses en computer screenshots. En-passant signaleert hij trends en ontwikkelingen, bijvoorbeeld op het gebied van HF e-mail. Waarom is Pactor-2 in feite de standaard geworden en bijvoorbeeld niet Clover-2000? Het antwoord op deze en andere vragen is in het Radio Data Code Manual te vinden. De beste maatstaf voor de kwaliteit van de informatie, is de indrukwekkende lijst van professionele klanten van Klingenfuss. In ons land hebben bijvoorbeeld het Ministerie van Defensie, de Koninklijke Landmacht en de NAVO boekwerken van Klingenfuss op de plank staan."
Richard Olesen, United States of America - 26 March 2003: "I just received the new Radio Data Code Manual. Very informative. Your hard work is reflected in the book. Nice Job. I really like the quality of the page stock. There are a lot of useful references."
Ari Tiiska, Finland - 12 December 2002: "Radio Data Code Manual ... 2003 Guide to Utility Radio Stations ... Thanks once more for your excellent books. This kind of information is very difficult to find elsewhere."
Steve Ford WB8IMY, Managing Editor, in American Radio Relay League QST - August 2001: " If you are tempted to go snooping outside the ham bands with your digital decoder, the Radio Data Code Manual is a vital reference that will make it possible for you to interpret the gibberish you often see on your monitor."
Anker Petersen, Chairman of Danish Shortwave Clubs International, in Shortwave News - February 2003: "I found the following details essential for the DXer during his listening and identification of the transmitter and broadcast: station name, exact language, scheduled broadcast time, exact frequency and transmitter site. For identification purposes, it is necessary that all the essential details are readily available in the handbook. This was found to be the case in 68% of the checks in the WRTH, and 74% in the Shortwave Frequency Guide. The German editor Joerg Klingenfuss and his staff have put a lot of effort to make it as up-to-date as possible and it is slightly more accurate than the WRTH in the details. Its big advantage is that for each SW frequency you can read at what time it is used by various broadcasters and in which language."
Md. Azizul Alam Al-Amin, Bangla Desh - 31 December 2002: "I would like to take the opportunity to show my heartfelt gratitude and thanks for sending your excellent 2003 Shortwave Frequency Guide ... The guide is quite informative and exclusive. I have told to some of my DX-er friends about it ..."
Richard D'Angelo, Executive Director, North American Shortwave Association - 13 December 2002: "2003 Shortwave Frequency Guide... Mailed monday, and arrived today, Thursday ... very fast! ... another excellent edition of this very valuable resource."
Dick Richardson, United Kingdom - 11 December 2002: "2003 Shortwave Frequency Guide ... I have only had the chance to look at it for one hour and already it is my favourite radio handbook - well done. I will see you next year for sure. In the meantime when I can afford it I would also like to get the CD version. Many thanks for a useful book, and prompt service, and one (if not the only one which I have) which already seems to be up to date with its information - IT WORKS."
Michiel Schaay at 7 January 2004 on www.kortegolf.info and in Radio Amateur Magazine, Netherlands, February 2004: "2004 Guide to Utility Radio Stations ... Eén van de meest opmerkelijke ontwikkelingen op dit gebied, is de toename van het aantal ALE-signalen. Steeds meer communicatiestations gaan ertoe over om onderlinge HF-verbindingen op te starten met het Automatic Link Establishment systeem, kortweg ALE genoemd. Deze sterke stijging van het aantal ALE-gebruikers komt ook tot uiting in de editie 2004 van de Klingenfuss-gids. Het in kaart brengen van digitale kortegolf transmissies is sinds jaar en dag een sterk punt van de Guide to Utility Radio Stations. De nieuwste editie onderstreept dat nog eens. Maar natuurlijk komen ook een groot aantal stations in enkelzijband, morse en fax aan bod in de nieuwe frequentiebijbel van Klingenfuss. Zoals gebruikelijk omvat de 22e editie ook een waaier aan informatie, die wordt verdeeld over gerangschikte overzichten en redactionele artikelen. De actiefste signaaljagers onder u zullen zeker geen editie willen missen. De verzameling van uw redacteur begint bij de uitgave van 1985. Zo'n serie vuistdikke boekwerken biedt uiteraard een fraaie en goed gedocumenteerde kijk op van het gebruik van de kortegolf gedurende de laatste twee decennia. - 2004 Shortwave Frequency Guide ... Het kan echter nog completer, want in zijn Shortwave Frequency Guide combineert Klingenfuss zijn database van communicatiediensten met een kwalitatief hoogstaand bestand van actuele omroepfrequenties. Maar met in totaal 20300 frequenties krijgt de lezer de beschikking over een alomvattend naslagwerk, dat zijn weerga niet kent. - Overigens vinden we alle frequenties uit het boekwerk terug op een door Klingenfuss uitgebrachte CD. Deze 2004 Super Frequency List on CD bevat bovendien een archief van 19600 inactieve frequenties en geeft ons daarmee een interessante terugblik op het verleden. Alle gegevens op deze CD zijn toegankelijk via een meegeleverd databaseprogramma, dat draait onder de besturingssystemen Windows 3.1, 95, 98, 2000, ME, NT en XP. Vanzelfsprekend zijn er allerlei zoekacties en sorteringen mogelijk."
D Graham Scott, United Kingdom - 14 December 2004: "Having installed the WAVECOM W40PC DSP Digital Data Decoder Card, it appears to be better than my older Hoka C3 Gold (it runs under Windows!). I'm now looking for that "special" signal to decode, but I should probably read some more of the manual first!"
Matthias Zweigert, Cameroon - 7 January 2004: "2004 Super Frequency List on CD ... ist wirklich super und im Gegensatz zu Ihren früheren "Wälzern" enorm anwendungsfreundlich. Meinen besten Glückwunsch zu diesem Werk!"
Bob Padula, Australia, in Electronic DX Press - 31 January 2003: "The latest edition of the 2003 Super Frequency List on CD reflects the continuing and ongoing use of this modern medium for presentation of a massive amount of vital and accurate data in support of world HF broadcasting. No complex set-up, installation or configuration is necessary - the disk is inserted into the drive and the data is immediately available. The data is searchable by various methods, and access time is extremely short, in milliseconds. The order and width of the columns can be varied by the user. I called up details of all stations broadcasting in Latin, and their times and frequencies - I was surprised to note two broadcasters in that search - Vatican and Finland. I also asked for data for all stations using the Irkutsk relay - 27 entries were revealed. I found that there is only one station broadcasting in Ladino (Israel), and one in Icelandic (Iceland). Oromo, the language spoken in East Africa, was shown as being used by eight broadcasters, and all necessary data was given. Searching for complete schedules for specific broadcasters is straightforward. DX specialist monitors will find this product to be extremely useful in assisting in station identification, where various search routines may be called up, whether for domestic/international/clandestine broadcasting services or utility. Particularly neat is the "concurrent search" program, which when sued in combination with the incremental search represents a very powerful tool. A search for all broadcasters using the Al Dhabayya relay centre in Abu Dhabi gave us 131 results, in 1 millisecond - that sort of search routine is an excellent example of what can be accomplished with this disk. Program listeners may use the disk to obtain details of an almost infinite number of permutations, such as "all broadcasts in Arabic at 0615 UTC". Many entries will be found for the emerging new technology known as "HF E-mail", claimed to be more cost-efficient than traditional satellite radio systems, with transfer rates of 2.4 kB now commonplace, with a possible 32 kB within reach. I met with Joerg at his home some three years ago when I visited Germany, and was impressed with his dedication and superb attention to detail and topicality of all products and services he offers. This product is a very useful tool for anyone involved in HF broadcasting. I have used the CD for many years as an important adjunct not only in support of my professional work associated with broadcast engineering, but also for my hobby interests in world radio. I would recommend it to anyone with an active interest in all forms of HF radio monitoring."
Mike Richards G4WNC, Decode editor of Shortwave Magazine, United Kingdom - February 2003: "Despite the the rapidly increasing use of the Internet, the 2003 Guide to Utility Radio Stations remains the most usable reference for most listeners. One of the sections I always find particularly useful is the station list. This may not sound that exciting, but the real hidden gem is the way the list is formatted. Rather than listing in station or frequency order, the list is based on countries and then sorted by service. This arrangement really speeds up the search process. For example, if you wanted to find meteorological HF stations in Kenya you just look-up Kenya, then MET and you will find Nairobi Met listed with all its operating frequencies. Another real timesaver is the meteorological radiofax and radiotelex listing."
John Kench G8JTQ, United Kingdom - 16 January 2003: "Have been looking at your website - absolutely magic! Saving up for a WAVECOM!!"
Radio Nederland's Real Radio Booklist Review - 9 January 2003: "2003 Guide to Utility Radio Stations ... If you're interested in the signals between the broadcast bands, this guide is the acknowledged leader. A comprehensive guide to codes and abbreviations used in practice. Published in December, the book has a quick production turn-around time."
Radio Monitoring Station, Station Manager, Greenock, Scotland, United Kingdom - 12 December 2002: "2003 Guide to Utility Radio Stations ... 2003 Super Frequency List on CD ... Thank you again for your wonderful products."
Paolo Valfré I1VPJ, Italy - 12 December 2002: "2003 Guide to Utility Radio Stations ... Complimenti per le tue pubblicazioni!"
Sheldon Harvey, Canada, in The Radio H.F. Internet Newsletter - September 2002: "Joerg Klingenfuss is one of the world's best known utility radio monitors. For those who monitor two-way utility radio traffic on the HF bands, his publications and CDs are essential reference guides. His material is highly respected, well researched, constantly updated, detailed and precise. Although these reference guides are often more costly than others on the market, they are well worth the investment for the serious radio monitor."
Michel Lacroix, France - 18 October 2003: "Salutations et mes compliments pour l'Utility Guide que je lis depuis des années."
Robert T Combs, United States of America: "I have used your publication since I received it and have it found it to be highly accurate on all of the signals I have received. I have purchased your book many times in the past."
Allen Fountain, Utility editor of Australian DX News - 6 August 2003: "Have downloaded the new software for the WAVECOM W40PC. I have to say that my decision to select the WAVECOM back in February 2001 was correct. I was very pleasantly surprised to find that, in addition to the new modes, there were a number of additional operational features, also a new manual. It was just like getting a new decoder."
Dirk van de Wal, Utility Mozaiek editor of DX Antwerp, Belgium, in Bulletin July 2003: "De Radio Data Code Manual is reeds jaren het standaardwerk op gebied van de digitale datatransmissie ... Voor wie echt ge interesseerd is in digitale datatransmissie en daarbij tot op de bodem wil gaan mag dit boek onmisbaar genoemd worden."
Damian P Geiss AC7RG, United States of America - 25 June 2003: "I just wanted to email you and thank you for the outstanding Compact Disc Recordings of Modulation Types. I listened to all four last night and they are absolutely fantastic in quality. A great assistance in my research."
Angelo Brunero IK1QLD, CISI, Università di Torino, Italy - 18 June 2003: "Un paio di pubblicazioni che spesso consulto per sapere qualcosa in più sono Shortwave Frequency Guide (Worldwide HF Communications Today) e Guide to Utility Radio Station di Joerg Klingenfuss, una vera manna nel campo del radioascolto."
Sergey M. Kolesov, Ukraine - 13 May 2003: "Thank you for prompt delivery of the 2003 Shortwave Frequency Guide and the 2003 Super Frequency List on CD. I have reviewed them and found that they are really reliable source of frequencies of utility stations."
Dave Thorne, Australia - 12 May 2003: "Radio Data Code Manual ... It is very good and right up to date. Thanks very much for your efforts, and I can thoroughly recommend this publication for serious surveillance work."
Bob Grove W8JHD, Chief Editor, in Monitoring Times, United States of America - May 2002: "Radio Data Code Manual ... The age of digital electronics has spawned an incredible array of special languages and cyphers for exchange of communications. Nowhere is this assemblage more visible than on the HF spectrum. Dozens of proprietary systems and algorithms multiply into hundreds of variants heard as beeps and buzzes as the listener tunes through the 1.8-30 MHz spectrum. For the curious, stand-alone decoders and computer software programs abound, but recognition is still a problem - unless you have a comprehensive guide such as the manual from Klingenfuss. A massive 600 pages of illustrated information, the code manual provides an orientation to nearly every data transmission likely to be encountered on the air, along with lists of sources for decoding software and hardware. Massive details are provided for interpreting codes encountered on the airwaves. This comprehensive reference is an outstanding companion for users of the sophisticated WAVECOM decoders."
Harald Kuhl, Buchbesprechungen editor of Radio-Kurier Weltweit Hören, Germany - 15 April 2003: "Die Firma WAVECOM hat unter den Dekodern digitaler Übertragungssysteme einen vergleichbar legendären Ruf wie Rohde + Schwarz bei der Sende- und Empfangstechnik: es gibt kaum etwa besseres. Mehr als 110 Systeme kann ein WAVECOM-Dekoder mittlerweile erkennen und auf den Bildschirm bringen. Regelmäßige Updates werden von WAVECOM kostenlos zur Verfügung gestellt, so daß das System im Laufe der Zeit immer leistungsfähiger wird."
Michiel Schaay at 3 April 2003 on http://www.kortegolf.info and in Radio Amateur Magazine, Netherlands, May 2003: "Radio Data Code Manual ... een werkelijk goed inzicht te verwerven in de digitale transmissiesoorten en –protocollen die de kortegolf bevolken. Gerichte zoekopdrachten op het internet kunnen veel interessante informatie boven water brengen. Toch blijft er altijd behoefte aan een gedrukt overzichtswerk. In zijn Radio Data Code Manual brengt Klingenfuss een grote hoeveelheid relevante informatie samen. Gewapend met dit 600 pagina's tellende boekwerk, kan de toegewijde hobbyist zich stap voor stap een weg banen in de (soms ondoorzichtige) wereld van de professionele kortegolf communicatie. Klingenfuss rafelt een aantal belangrijke digitale transmissietechnieken uiteen, ruimschoots geïllustreerd met signaalanalyses en computer screenshots. En-passant signaleert hij trends en ontwikkelingen, bijvoorbeeld op het gebied van HF e-mail. Waarom is Pactor-2 in feite de standaard geworden en bijvoorbeeld niet Clover-2000? Het antwoord op deze en andere vragen is in het Radio Data Code Manual te vinden. De beste maatstaf voor de kwaliteit van de informatie, is de indrukwekkende lijst van professionele klanten van Klingenfuss. In ons land hebben bijvoorbeeld het Ministerie van Defensie, de Koninklijke Landmacht en de NAVO boekwerken van Klingenfuss op de plank staan."
Richard Olesen, United States of America - 26 March 2003: "I just received the new Radio Data Code Manual. Very informative. Your hard work is reflected in the book. Nice Job. I really like the quality of the page stock. There are a lot of useful references."
Michiel Schaay, Netherlands, 19 March 2003: "Radio Data Code Manual ... is really a goldmine!"
Gayle and Larry van Horn, Assistant Editors of Monitoring Times, United States of America - March 2003: "It is the digital utility station listings that really make the 2003 Guide to Utility Radio Stations stand out. His listing of digital mode stations are exhaustive. No other radio hobby publication has the scope and depth of coverage of digital radio networks as the Klingenfuss publications. - 2003 Shortwave Frequency Guide ... Each year, I add this informative source, along with other DXing publications, as an aid in my personal monitoring sessions. It remains my favourite. Plain and simple ... it is very user-friendly ... This is the only publication that combines shortwave broadcast and utility stations in one volume. I have used Klingenfuss frequency guides for years."
John Kench G8JTQ, United Kingdom - 19 February 2003: "2003 Super Frequency List on CD ... 2003 Shortwave Frequency Guide ... At this early stage I am very impressed with both the book and CD, and confident that they will provide the information when and how I will require it."
Lee Jessup, United Kingdom - 7 February 2003: "2003 Shortwave Frequency Guide ... Being relatively new to the hobby, I was very pleased to note how easy the guide is to use considering how comprehensive it is. Well done to you and all your contributors."
Peter de Vroome PE1DTN, Netherlands - 8 February 2003: "2003 Super Frequency List on CD ... keep on doing your good work!"
Harald Kuhl, Buchbesprechungen editor of Radio-Kurier Weltweit Hören, Germany - 15 February 2003: "2003 Shortwave Frequency Guide ... hat gegenüber anderen Frequenzwerken den Vorteil, daß es sich nicht auf die Darstellung von Empfangsmöglichkeiten in einer bestimmten Region der Erde konzentriert. Die Darstellung der Daten ist zwar betont nüchtern gestattet, doch dafür angenehm umfassend und komplett."
Thieu Mandos NL199, NL-Post editor of VERON, in Electron, Netherlands - February 2003: "Wie alles wil weten van coderings-technieken kan ik het Radio Data Code Manual aanbevelen. - 2003 Super Frequency List on CD ... een fascinerende CD ... De kwaliteit van de vermelde stations is uitstekend. De gegevens zijn niet blindelings gekopieerd uit overzichten en andere lijsten. Het gemak waarmee je kunt zoeken is echt een genot. - 2003 Guide to Utility Radio Stations ... Dit is een standaardwerk voor wie geïnteresseerd is in utility stations. Met die boek in de hand kun je de meeste geheimzinnige signalen snel ontmaskeren. De kwaliteit van de informatie staat hoog in het vaandel van de Klingenfuss organisatie. Als een signal 15 maanden niet meer gehoord is wordt het afgevoerd naar de lijst met voormalige stations. In de actuele lijst is dan ook elk jaar weer de helft veranderd. Zeker de laatste paar jaar is er veel veranderd op de kortegolf. Het boek is echt een gids voor wie de kortegolf wil ontdekken. - De 2003 Shortwave Frequency Guide is een bijzonder handig boek bij onze speurtochten op de kortegolf. Het blinkt uit in informatiedichtheid en actualietit."
Mike Richards G4WNC, Decode editor of Shortwave Magazine, United Kingdom - February 2003: "Despite the the rapidly increasing use of the Internet, the 2003 Guide to Utility Radio Stations remains the most usable reference for most listeners.

Another real timesaver is the meotorological radiofax and radiotelex listing. - The 2003 Super Frequency List on CD continues to improve with every edition. This latest version is lightning fast. The most powerful is the word search. Rather than a simple word search orn a single word or phrase, you can build your own very specialized searches to dig out just what you want. This is an incredibly fast and powerful search system that really allows you to make the most of the 10,000+ frequency list."
Nils Schiffhauer DK8OK, editor of Funk, Germany - February 2003: "Seit beinahe undenklichen Zeiten bringt der Welt- und Wellenreisende Jörg Klingenfuss seinen jährlichen 2003 Guide to Utility Radio Stations unter die Leute. Der Meister hatte wieder einmal recht, wenn er einen steigenden Anteil privater Funkdienste, Militärfunk und die Kurzwelle als kostenlosen E-Mail-Ersatz prophezeite. Der 2003er-Jahrgang dokumentiert den Wahrheitsgehalt von Jörgs fundierten Vorhersagen auf eindrucksvolle Weise. 34 Jahre Erfahrung fließen auch in der 21. Auflage des Guide to Utility Radio Stations zusammen. Jörg weiß bei jedem Detail, von was er redet. Auch sein 2003er-Guide ist wiederum unverzichtbar für jeden, dessen HF-Horizont nicht beim Bayerischen Rundfunk endet. Er sollte zudem Pflichtlektüre für jeden Funkamateur sein, der daran sehen kann, wie dank neuer digitaler Betriebsarten der Äther brennt wie selten zuvor."
Anker Petersen, Chairman of Danish Shortwave Clubs International, in Shortwave News - February 2003: "I found the following details essential for the DXer during his listening and identification of the transmitter and broadcast: station name, exact language, scheduled broadcast time, exact frequency and transmitter site. For identification purposes, it is necessary that all the essential details are readily available in the handbook. This was found to be the case in 68% of the checks in the WRTH, and 74% in 2003 Shortwave Frequency Guide. The German editor, Joerg Klingenfuss, and his staff has put a lot of effort to make it as up-to-date as possible and it is slightly more accurate than the WRTH in the details. Its big advantage is that for each shortwave frequency you can read at what time it is used by various broadcasters and in which language."
Bob Padula, Australia, in Electronic DX Press - 31 January 2003: "The latest edition of the 2003 Super Frequency List on CD reflects the continuing and ongoing use of this modern medium for presentation of a massive amount of vital and accurate data in support of world HF broadcasting. No complex set-up, installation or configuration is necessary - the disk is inserted into the drive and the data is immediately available. The data is searchable by various methods, and access time is extremely short, in milliseconds. The order and width of the columns can be varied by the user. I called up details of all stations broadcasting in Latin, and their times and frequencies - I was surprised to note two broadcasters in that search - Vatican and Finland. I also asked for data for all stations using the Irkutsk relay - 27 entries were revealed. I found that there is only one station broadcasting in Ladino (Israel), and one in Icelandic (Iceland). Oromo, the language spoken in East Africa, was shown as being used by eight broadcasters, and all necessary data was given. Searching for complete schedules for specific broadcasters is straightforward. DX specialist monitors will find this product to be extremely useful in assisting in station identification, where various search routines may be called up, whether for domestic/international/clandestine broadcasting services or utility. Particularly neat is the "concurrent search" program, which when sued in combination with the incremental search represents a very powerful tool. A search for all broadcasters using the Al Dhabayya relay centre in Abu Dhabi gave us 131 results, in 1 millisecond - that sort of search routine is an excellent example of what can be accomplished with this disk. Program listeners may use the disk to obtain details of an almost infinite number of permutations, such as "all broadcasts in Arabic at 0615 UTC". Many entries will be found for the emerging new technology known as "HF E-mail", claimed to be more cost-efficient than traditional satellite radio systems, with transfer rates of 2.4 kB now commonplace, with a possible 32 kB within reach. I met with Joerg at his home some three years ago when I visited Germany, and was impressed with his dedication and superb attention to detail and topicality of all products and services he offers. This product is a very useful tool for anyone involved in HF broadcasting. I have used the CD for many years as an important adjunct not only in support of my professional work associated with broadcast engineering, but also for my hobby interests in world radio. I would recommend it to anyone with an active interest in all forms of HF radio monitoring."
Borja Marco, Spain - 29 January 2003: "Radio Data Code Manual ... 2003 Guide to Utility Radio Stations ... 2003 Shortwave Frequency Guide ... Excellent quality books."
Curtis Cochran KG6IXW, United States of America - 27 January 2003: "Your 2003 Shortwave Frequency Guide is fantastic."
David Fleming NS8S, United States of America - 23 January 2003: "Enjoy your website too! Fantastic!"
John Kench G8JTQ, United Kingdom - 16 January 2003: "Have been looking at your website - absolutely magic! Saving up for a WAVECOM!!"
Kaj Bredahl Jørgensen, Editor-in-chief of Danish Shortwave Clubs International, in Shortwave News, Denmark - 14 January 2003: "2003 Super Frequency List on CD ... 2003 Shortwave Frequency Guide ... you have done again a very good job."
Radio Nederland's Real Radio Booklist Review - 9 January 2003: "2003 Guide to Utility Radio Stations ... If you're interested in the signals between the broadcast bands, this guide is the acknowledged leader. A comprehensive guide to codes and abbreviations used in practice. Published in December, the book has a quick production turn-around time. - 2003 Super Frequency List on CD ... an extremely comprehensive and accurate list ... A powerful concurrent full text word search is included as well. - 2003 Shortwave Frequency Guide ... an extremely comprehensive and accurate list, in frequency order ... also includes over 100 pages of broadcast station schedules by country in alphabetical order. The book has a quick production turn-around time. This book is ideal if you scan the dial methodically and want a book that will help you identify mystery stations. Klingenfuss bases his material on actual monitoring by a worldwide team of over 100 people. Highly recommended. - This review was compiled by the staff of 'Media Network', the English language webzine of Radio Netherlands. The review was done independently of the author and publisher. Radio Netherlands has no financial connection with either and provides the information above in good faith."
Lee Reynolds in Monitoring Times, United States of America - January 2003: "The WAVECOM W40PC DSP Digital Data Decoder is a well-designed and laid-out device. On HF performance was excellent. One item under the heading of "eye candy" that I really liked is the ability to select different palettes for the tool displays - it makes interpreting things like waterfall displays much easier when various attributes are properly colour-coded. As you can tell, I like this device. I liked it well enough to have purchased one some months ago. I have a reasonable wide experience of digital transmission decoding hardware (Hoka, Universal et al) and the Wavecom is my firm favourite, because it offers an excellent compromise between quality, features and cost. If you're in the market for a high-end decoder, I can definitely recommend the Wavecom line of products. Not only are they well designed, they're well supported and Wavecom honestly admit to any problems you may encounter, happily working with you to resolve the matter. Feature set and cost is only half the value here - a manufacturer that acknowledges the hobbyist's existence is the other. One big plus for this device is that software updates are reasonably regular and, importantly, free! Wavecom exhibits a mentality that takes into account the low-end purchaser, not just the corporate/governmental buyer. This compares extremely favourably with a competitor's offering of a 3.5" diskette with the latest software upgrade for their hardware for a mere USD 400. I may be crazy enough to be a digital utility monitor but I'm not crazy enough to pay that kind of money for a merely incremental software upgrade as well!"
Md. Azizul Alam Al-Amin, Bangla Desh - 31 December 2002: "I would like to take the opportunity to show my heartfelt gratitude and thanks for sending your excellent 2003 Shortwave Frequency Guide ... The guide is quite informative and exclusive. I have told to some of my DX-er friends about it ..."
Michael Bente, United States of America - 31 December 2002: "2003 Guide to Utility Radio Stations ... 2003 Super Frequency List on CD ... 2003 Shortwave Frequency Guide ... Guide to Worldwide Weather Services ... I have purchased from you several items over the past years, and thank you very much for the support it has given me in my hobby of shortwave listening."
Michiel Schaay at 23 December 2002 on http://www.kortegolf.info and in Radio Amateur Magazine, Netherlands, February 2003: "2003 Guide to Utility Radio Stations ... 2003 Super Frequency List on CD ... 2003 Shortwave Frequency Guide ... Het trio vormt een ware goudmijn voor de doorgewinterde kortegolf hobbyist. Ook professionele telecomwerkers gebruiken de Klingenfuss-gidsen. De frequentiegidsen en -bestanden van de Duitse kortegolf specialist zijn voornamelijk opgebouwd uit zijn eigen waarnemingen en die van enkele medewerkers. Voor de ontvangst van telexuitzendingen in alle mogelijke transmissie protocollen is het boekwerk in feite onmisbaar."

Anthony J Harding, United Kingdom - 7 December 2002: "Once again, for the seventh year running, Klingenfuss Shortwave Frequency Guide is packed from front cover to back with USEFUL information. Every page of your publication is of interest to the shortwave listener without having to skip pages of advertising and sponsorship. I have purchased a copy of this book every year since first published in 1997 and will continue to do so along with the excellent Super Frequency List on CD. I would recommend all radio enthusiasts who purchase data by mail order to use Klingenfuss. Your publications and your delivery times are second to NONE."

Sheldon Harvey, Canada, in The Radio H.F. Internet Newsletter - September 2002: "Joerg Klingenfuss is one of the world's best known utility radio monitors. For those who monitor two-way utility radio traffic on the HF bands, his publications and CDs are essential reference guides. His material is highly respected, well researched, constantly updated, detailed and precise. Although these reference guides are often more costly than others on the market, they are well worth the investment for the serious radio monitor."
Hans Kulk NL12972, Netherlands - 31 August 2002: "Compact Disc Recording of Modulation Types .. The CD's are of great interest to me personally because at home I'm a radio listener from 40 kHz to 300 MHz. The CD's contain very good samples of all kinds of radiocodings and is indeed very helpful in finding out whats going on."
Robert J Inderbitzen NQ1R, Marketing Coordinator, in American Radio Relay League QST - April 2002: "... details on how to listen in on the newest, most secretive shortwave digital modes including commercial HF e-mail! Relied on by professional and hobbyist listeners for years, Klingenfuss publications are known for their thoroughness and accuracy."
Bob Grove W8JHD, Chief Editor of Monitoring Times, United States of America - March 2002: "For combination utilities/broadcast listeners who want a ready, comprehensive reference, nothing can beat the 2002 Shortwave Frequency Guide.

David Stoddard, United States of America - 14 February 2002: "Just wanted to send you a .w40 file of a recent Sailmail transmission. I've just recently purchased my WAVECOM W40PC and I'm having a blast with it. I'm using it in conjunction with a T2FD and a Ten-Tec RX340. I really enjoy your website along with your publications and frequency database."
Dr.-Ing. Werner Hegewald DL2RD, Chief Editor of Funkamateur, Germany - February 2002: "2002 Guide to Utility Radio Stations ... Der Kurzwellenfunkverkehr ist für den ambitionierten Beobachter spannender denn je geworden. Dies ist mit erheblichem Wildwuchs in bezug auf Frequenznutzung, Rufzeichengebrauch etc. verbunden - für den Herausgeber und sein Team eine gewaltige Herausforderung, stützt sich doch das vorliegende Werk ausschließlich auf akribisch zusammengestellte reale Beobachtungen und nicht auf im Internet in Hülle und Fülle zu findende Halbwahrheiten zweifelhafter Natur."
Kevin Nice G7TZC, Chief Editor of Shortwave Magazine, United Kingdom - January 2002: "WAVECOM W40PC DSP Digital Data Decoder Card ... This decoder represents the leading edge of the shortwave listening hobby. With the W40PC you can intercept and display traffic that originates from systems that utilize very complex engineering to pass information at an ever increasing rate ... for less money than that required to purchase a large wide-screen TV set. If you are serious about data modes, and I do mean serious, then you will need much more than a shareware decoder. I've been using this Wavecom for a good few weeks and there's no doubt it is a joy to operate ... a very lively, rapidly updating spectrum display."
Wilfried Melchior, Germany - 18 December 2001: "Die Auflistungen mit den Zeiten sind wunderbar übersichtlich. Bei der Aktualität und Übersichtlichkeit kann ich in Zukunft beruhigt auf andere Werke verzichten. Besonders imponieren mir die Sendezeiten innerhalb der Frequenzliste und daß dort auch ausreichend Platz für Notizen vorhanden ist, um gegebenenfalls aktuelle Veränderungen zu vermerken - das reicht, bis man mit Spannung wieder die neue Ausgabe erwartet."
Barry Harding, United Kingdom - 13 December 2001: "My order which you dispatched this Monday arrived on Wednesday. I am very impressed by your fast efficient service. Initial look at the Super Frequency List on CD and the Guide to Utility Radio Stations look very interesting, excellent value with features that will greatly enhance my hobby.

Kaj Bredahl Jørgensen, Editor-in-chief of Danish Shortwave Clubs International, in Shortwave News, Denmark - January 2002: "2002 Shortwave Frequency Guide ... I find it very easy to use compared with other radio handbooks. This system is just brilliant, when you're searching the bands. When you listen to a certain frequency, then you look at the time you're listening, and then you have the station you're listening to. It can't be more easier. Of all those stations I have been listening to, just a very few errors were found. I can only recommend this unique book strongly."
Harald Kuhl, Buchbesprechungen editor of Radio-Kurier Weltweit Hören, Germany - 15 January 2002: "2002 Guide to Utility Radio Stations ...

It's accurate and therefore a great source of information. "
Guido Schotmans in DX Antwerp Bulletin, Belgium - January 2002: "2002 Shortwave Frequency Guide ... De correctheid van de listings is erg groot. En voor tropenband frequenties blijkt het boek een pluspunt te zijn. Je vindt er soms actieve stations in terug die in andere lijsten niet vermeld staan.

Mike Richards G4WNC, Decode editor of Shortwave Magazine, United Kingdom - September 2001: "WAVECOM W41PC DSP Digital Data Decoder Card ... immense processing power ... the whole thing was very fast and responsive because there wasn't the lag that you tend to get with PC soundcard based systems. An excellent system of measurement cursors was built into all the analysis display modes and really made the W41PC an extremely powerful analytical tool. Fax signals ... the W41PC delivers the best balance of performance and features that I've seen in any system. Speed and phase adjustment are so well thoughtout they made fax reception a real dream. Excellent owner's manual ... a very sophisticated decoding and analysis system. You can sense the processing power as soon as you start to use it because all the signal displays are so much more lively than many soundcard based systems."

Außerdem ist trotz vieler Soundcard-Ansätze damit nur ein Bruchteil der mit der W40PC-Karte mitzulesenden Sendungen dekodierbar. Und manches kann eine Soundcard eben gar nicht leisten. Wer eine zeitgemäße und professionelle Dekodier-Möglichkeit sucht, für den ist die W40PC-Karte eine sowohl kompromißlose als auch noch bezahlbare Lösung."
