Hot Frequencies and
Digital Data Transmission Screenshots

The following - very recent! - screenshots have been produced and uploaded to this international pooling webpage by our worldwide net of cooperators, using advanced equipment such as the superb PROCITEC Digital Data Decoders. All frequencies are in kHz, and all system times are UTC. Schedules and traffic details can be found in our 2025/2026 Guide to Utility Radio Stations. Standard aeronautical • meteorological • telecommunication abbreviations and ICAO Airport Codes and Airline Designators can be found everywhere; certain very special procedures and terms - particularly for avionics - are explained hereunder. Latest screenshots on top!

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
