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 and WAVECOM Digital Data Decoders. All frequencies are in kHz, and all system times are UTC. Schedules and traffic details can be found in our 2021/2022 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.

What those megalomaniac Communist Chinese call "Zengmu Ansha Reef"
is in fact James Shoal, recognized by the Brits in the early 19th Century

Needless to say, located a mere 83 kilometres off Bintulu in Sarawak,
BETING SERUPAI belongs perfectly to the continental shelf and EEZ of MALAYSIA,
and has never repeat NEVER been a territory of Communist "China"
that is more than 1,800 kilometres repeat

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
