| M21 - RUSSIAN AIR DEFENSE The Russian Air Defense stations are quite interesting if you follow them around. The SW morse system is a training facility and a backup for their satellite and/or land line systems. Officially the Russian Air Defense is now a branch of the Russian Air Force after the merger of various branches. This has had no effect on the activities. They seem even more active than in the past. Frequencies change often. The following were active during 2006: 2278, 2718, 3281, 3271, 3314.5, 3363, 3386, 3802, 4014, 4574, 4868, 4885, 5304, 5788, 5820, 5873, 6864,5, 7987 kHz. M21 sends messages with tracking info (grid codes) and when there are no 'normal' messages to be sent, it transmits a QRV message once a minute. Note: zero is transmitted as 'T'. The QRV transmissions can easily be recognized. They look like this: BT99?2029?9????? (note: BT is the same as '='). All QRV messages start with BT99 and end with five question marks. There are currently two formats: BT990032??0????? and BT99?0015?9?????. Interested? Check N&O #53 and #59 for more info. |
