Firedrake jamming observations

CHINA
Firedrake feeds. So far the Firedrake jamming feeds appear to havehad a common source, the delays between different transmitters having beennormal for satellite feeds. Today, however, I noted a change to threedifferent feeds, all apparently carrying the usual "programme", but withwidely different starting times.

As it seems, there is a main feed,carried by several jamming stations, and two separate feeds, each beingcarried by one specific jamming station only (synchronized audio for alltransmitters carrying the respective feed).

Frequencies noted:
1000: Main - 14500, 13970, 13765, 13650, 9855, 9200 separate A: 10400 separate B: 116651100: Main: 15375, 12040, 11590, 11540, 9680, 9200, 7470 separate A: 11750, 10400, 9605 separate B: 15545, 11785, 116651200: Main: 13625, 11590, 11540, 9425, 9200, 7470 separate A: 11775 (from 1215), 11750, 11710, 10400, 9605 separate B: 15545, 11785, 9680 (transmitter change on 9680)

Not only Mandarin, but also Tibetan and Uzbek are being jammed, Iconfirmed that yesterday. However, the latter two languages are onlyjammed by one or two jammers, usually with Firedrake. Uighur usually isalso heavily jammed, while Cantonese is free of jamming. Firedrake is ofcourse only a complement to the dominating CNR-1 jamming signals.
