For 36 years, we have been the world's leading publisher of books and CDs for professional shortwave (HF) radio monitoring. On our Internet pages you will find fascinating live radio monitoring screenshots plus dozens of sample pages from our unique products. A brandnew CD gives you more than 3,900 (three thousand nine hundred!) digital data decoder screenshots from our continuous HF radio monitoring between 1997 and today!

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

The selection from our long list of professional customers reads like the Who is Who? in this fascinating field. The continuous correspondence with our worldwide reading public ensures our manuals to continue to be the standard references of both professional monitoring services and non-professional radio listeners.

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!
