I’ve noticed a broadcaster that routinely transmits weekends at 11:00 UTC on 6,970 kHz. Some mornings, it’s much stronger than others. Saturday morning, my time, I managed to record it in its typical format: music. Specifically, Chinese folk music, at least so it sounds to my untrained ear.

I searched through logs and in the WRTH, and I could find no mention of a broadcaster on 6970 kHz. It doesn’t help that the 27 minute broadcast contained no audible IDs.

So, I’ve come to the conclusion that my initial hunch is correct–that this is the Chinese jamming service, Firedrake. Using Firedrake, the Chinese government transmits music on top of broadcasts they wish to block. It’s fairly effective (and annoying). While I’ve heard Firedrake a number of times over the bands, I can’t say I’ve ever tried to listen to the one-hour production.

The following recording contains a 27 minute broadcast of what I believe may be Firedrake on 6,970 kHz, starting around 11:00 UTC, Saturday January 26, 2013.

If you can confirm or correct my supposition, please comment!
