Chinese Firedrake Jammer on 13300 kHz

Another video in the popular "Firedrake" series: The Chinese music jammer on shortwave 13300 kHz received in Germany on 22 April 2010 at 14:40 UTC, presumably jamming Taiwan-based Sound of Hope Radio. Receiver: Lowe HF-225 Europa with Wellbrook ALA1530 magnetic loop antenna. Thanks to a channel free of any interference, I could choose the widest IF filter, providing excellent fidelity.

With a loop of non-stop classical Chinese music broadcast on many shortwave frequencies, the Chinese authorities try to block reception of certain foreign radio stations that are regarded as adversary. Among shortwave hobbyists (DXers), these transmissions are commonly called "Firedrake".

Does it still exist today? I don't hear it

[senderjaeger]

@ParanormalRob AFAIK, it still exists. If you don't hear it on this frequency, try other frequencies. You will certainly find the Firedrake if you scan the shortwave bands.

@senderjaeger So far, I haven't heard it. What are some frequencies and do we know why they are doing this?

[senderjaeger]

@ParanormalRob I myself haven't heard it either recently and I don't know whether or to what extent it is still active. You may try frequencies of the Chinese programs of VOA and Radio Free Asia (schedules are available on the stations' websites). I've just tried RFA Tibetan and had unjammed reception on 11590 and 15375 kHz.

And yes, we know why they are or were doing this. The answer is: censorship.

[rodriampuero]

love this radio tune, but I do not understand that blocks other frequencies, and this radio has a schedule or work at any time?

[senderjaeger]

@rodriampuero Hi, this "station" blocks frequencies for political reasons (censorship). Its broadcast times depend on the schedules of stations that are regarded adversary by the Chinese government.

If those jammers could play 24/7 pop music...

@ParanormalRob Heard yesterday afternoon (March 30th 2011) here in Ireland on 13130 and 14700

@senderjaeger Thanks for the info, i didn't know that

[senderjaeger]

@DanielChristy19 Shortwaves don't stop at borders but propagate around the world, almost regardless of the power. But the higher the power, the more efficient the jamming is.
