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 2023/2024 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.
