Shortwave broadcast dx-ers will probably have noticed the Chinese Firedrake Jammer interfering with broadcasts from Taiwan, the VoA, Radio Free Asia and the BBC World Service, though the details are new to me.

Several tx sites broadcast the feed from Chinasat 6B, which consists of a repeating one-hour sequence of the most strident and noisy traditional Chinese music, with lots of drums, gongs and cymbals. It is heard typically on the 7, 9, 11, 13, 18 and 21MHz bands, with a wide audio bandwidth

interestingly they jam programmes in Uzbek because its close enough to Uighur to be mutually intelligible.

this is the first year I haven't heard the firedrake in a long time, I've never known HF as bad as it is this year
