Up-to-date information on
frequencies, schedules, and digital data systems
for worldwide full-HF-coverage Kiwi-SDR and Web-SDR
decoding of professional digital data transmissions

For 49 years, we've been the world's leading publisher of books and databases for professional shortwave (HF) radio monitoring. Click here for dozens of sample pages of our latest products and here for hundreds of fascinating live radio monitoring screenshots. A brandnew USB stick gives you more than 14,500 (fourteen thousand five hundred!) digital data decoder screenshots from our continuous HF radio monitoring between 1968 and 2017!

Convenient HF radio monitoring on superb remote receivers

In urban areas all over the world, the radio spectrum is polluted, and that makes HF reception impossible in certain places. Fortunately, hundreds (!) of Kiwi-SDRs worldwide covering the complete 0-30 MHz spectrum have been made accessible via Internet here.

What's more, many radio amateurs, radio clubs, researchers, and universities have made available their SDRs e.g. here.

Contrary to the situation in the decreasing world of HF broadcasting, professional worldwide communication on shortwave - i.e. digital data transmissions of utility radio stations! - has been a superb success for decades. Global technical standards have been agreed upon many years ago, and innovative procedures and protocols resulted in a strong increase in the intelligent use of worldwide shortwave frequencies. Just think of ACARS/HFDL that currently handles more than 170,000 messages - per day! Then, there are thousands of HF networks using ALE. What's more, we've got hundreds of CODAN and PACTOR networks worldwide. For maritime traffic on MF and HF there is worldwide NAVTEX, DSC, and NBDPT. And so on ...


Real radio monitoring using the very latest digital data decoding software
The new go2monitor / go2signals decoder - at a cost of some 30,000+ EUR -
runs up to 32 classification / recognition / decoding / recording channels
within a large 1,600 kHz bandwidth of e.g. the Perseus SDR
Synchronization to professional PSK modes such as MIL-STD-188-110 A/B is very fast

HF is the only worldwide communications medium that is totally free of transmission time charges - an important factor today in the era of bankrupt economies, tight budgets and heavy cost control. It saves companies and organizations a major portion of their communications budget every year to use on more important things, because - once the equipment is installed - there are virtually no on-going costs.

There is not - and there will never be! - Internet access available all over the world. Says Horst Weise DL4SBK after his recent trekking trip to Ecuador: "I have been able to keep me very well informed with my 40 Euro portable shortwave receiver!" Now consider the absurd decision by leading international broadcasters to drastically reduce their worldwide shortwave transmissions ... or to shut down HF completely! Just how do BBC, Deutsche Welle, Voice of America and the like get their message - and mission! - across the border to the poor people that is most in need of independent information - and international support?


State-of-the-art digital data signals have been tested since 2013
by innovative broadcast stations such as the Voice of America ...

HF spectrum monitoring and control of harmful interference has been neglected for a long time. Today, up-to-date information on real spectrum occupancy - especially when it is based on real-time data such as ours - is invaluable for the planning of modern HF radio systems. Within living memory, bureaucratic government authorities - and, in particular, the International Telecommunication Union - have had absolutely nothing to offer in this field. The best data quality has been supplied from locations where we held instruction courses, e.g. Singapore (Yio Chu Kang monitoring station). By consequence, leading radio monitoring services routinely come back to us because we have been monitoring the HF spectrum continuously for 49 years.

Klingenfuss Publications and Klingenfuss Radio Monitoring are located in the countryside, far away from industrial noise and pollution. The digital panoramas hereafter (by Joerg Klingenfuss) are usually three-dimensional, i.e. they comprise not only one primitive row of blunt horizontal pictures, but multiple rows of vertical pictures instead, up to 360° x 180°!
