Hot Frequencies and
Digital Data Transmission Screenshots

Shortwave utility radio stations, partly monitored during our recent Malaysia Mauritius Reunion Rodrigues Sarawak Singapore monitoring missions.


A new USB stick gives you more than 18,000 (eighteen thousand!) digital data decoder screenshots from our continuous HF radio monitoring between 1997 and today! See the brandnew 2019/2020 Guide to Utility Radio Stations for more information such as schedules and traffic details. All frequencies are in kHz, and all system times are UTC. Our guidebook Radiotelex Messages includes hundreds of similar screenshots; that unique collection will give you an excellent overview on the state of the art in this fascinating field: think of worldwide terrorist networks using HF e-mail! For good reasons we lay particular stress on the fact that all screenshots were directly supplied by co-operating COMINT and ELINT and SIGINT units, equipment manufacturers abroad, and foreign radio monitoring experts beyond the reach of teutonic jurisdiction (German "authorities" simply click here!): just send us a short e-mail and attach a standard .w40 or .w41 or .w51 or .w61 or .wda file, then we have even your system's timestamps! The following - very recent! - screenshots were taken and uploaded independently to his pooling webpage by our worldwide net of cooperators, using advanced equipment such as the superb PROCITEC and WAVECOM Digital Data Decoders.

The Periodic Contract is a report sent every ... minutes
It specifies the reporting rate at which the avionics is required
to assemble and downlink the requested information to the ground system
The minimum reporting rate is usually not greater than every 14 minutes
but can vary to suit the need of the ground station
This procedure allows longitudinal and lateral separation of aircraft
in oceanic areas to be reduced to 30 nautical miles each
