Intercepting the Naval Air Transport Units starts with a surprise, as one wouldn't expect to be listening to Ground-Air Morse communications. The most rewarding frequency is 8816 kHz, but there are others as well. All transmissions, so far heard, are simplex networks.
CIS Naval Air Transports use many "X---" Four-Letter-Location-Indicators, which are not ICAO listed. In many cases the leading "U" has been replaced by "X".
Here are some airports often mentioned in Morse traffic:
Five Air Traffic Control Centers are responsible for all operations of Naval Air Transport. RCH84 sometimes is audible in Europe with reasonable signal strength, maybe it is relayed somewhere.
|Callsign||Callsign Voice Traffic||ATC Air Traffic Control||Possible region or location|
|RJF94||PRIBOJ||Air Transports Central Sector||Moscow|
|RJC38||NOVATOR||Air Transports Northern Sector||Murmansk Region. Airfields of Olenogorsk, Severomorsk or Kipelovo-Fedotovo.|
|RCB||KRAKET||Air Transports Western Sector||Kaliningrad Region. Airfields may be Chkalovsk, Chernyakhovsk, Donskoe and Khrabrovo.|
|RCH84||MONOLOG||Air Transports Eastern Sector||Vladivostok Region. Airfield of Knevichi.|
|RJC48||NORKA||Air Transports Southern Sector||Sevastopol Region. Airfield of Kacha.|
This is a typical example of traffic between aircraft and ATCs.
The 5-figure aircraft call sign corresponds to the Aircraft Registration Number which can be found in internet publications.

Sometimes the aircafts report their position:
QTH 59112140 which means: 59N11 21E40
QTH 56441954 which means: 56N44 19E54
