We have predicted already in 2000 that HF e-mail will continue to spread rapidly and will soon develop into the major application of modern digital HF techniques that we have marketed - and used! - for decades. Interestingly enough, the immense potential of HF e-mail has not been realized - let alone monitored! - by any other author and publisher so far.

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.

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 39 years. For decades, we have strived for the Asian approach to company qualities:

• innovative in responding to customer needs;
• high quality of services and products;
• management has long-term vision;
• financial soundness;
• company that others try to emulate.

We are a truly international publisher and, by consequence, all our products are in English. We do business worldwide and we do speak several languages: you may write us in Creole, English, French, German, Indonesian, Italian, Malay, Portuguese, or Spanish. The global coverage of our data bank is secured by regular overseas monitoring missions to the more interesting places in this world such as Alaska, Azores, Brunei, Canada, Djibouti, Dominica, Guadeloupe, Guatemala, Indonesia, Madagascar, Malaysia, Martinique, Mauritius, Philippines, Reunion, Rodrigues, Sabah, Saint Lucia, Sarawak, Singapore, Somalia, Venezuela, and Yemen!

Klingenfuss Publications and Klingenfuss Radio Monitoring are located in the countryside, far away from industrial noise and pollution ...

... a few kilometres outside of Tuebingen, the most beautiful city in Germany and always on the very top of the quality-of-life index throughout the country.

Tuebingen is located right in the geographical centre of the State of Baden-Wuerttemberg, the industrial centre of modern Germany and the leading export State within the nation, with global players such as Audi, Bosch, Mercedes, Porsche, SAP, Stihl, Wuerth and Zeiss, and the heartland of the superb German Mittelstand. The world-famous university has been founded by Count Eberhard Karl in 1477. Fortunately, we're a world away from strange places such as Berlin, the ideological centre of the German mezzogiorno and debladigarmen: GPS says 542 kilometres, and that's damned all right so!
