RFA, plus the style of programming, musical cues used by RFA, etc.
The ChiCom MUST jam everything in Chinese and some other languages from R.
Free Asia, and to do so they mostly employ the main homeservice program
CNR1, often with double audio feed/echo to make it more annoying to listen
to, sometimes also distortion, noise, off-frequency heterodynes, or
additional jamming sources such as Firedrake music. But it's mostly CNR1
and you can find // programming on countless other frequencies on lower
bands too, some of it axually intended for listening rather than jamming.
Of course the jamming transmitters are not listed as broadcasts in the
WRTH. The Aoki online frequency list does a good job of keeping up with
them, denoted by an asterisk next to the victim broadcaster.

Re: 21410 kHz InterModulation of China R Internat mix 21550 and 21690 kHz.
DJ9KR reported: Dear fellow Intruder Hunters,
Today I have agn heard at 0619 UTC and I am still hearing the IM3 of
ChinaRI on 21410 kHz. It is an IM product of 21550 and 21690 kHz. You find
the same px on all 3 QRGs. In addition there is a firedrake jammer on
21690 kHz.
The purpose of the transmission on 21550 and 21690 kHz is to jam western
Tx-ers. Direction is 80 degrs. from Southern Germany. Pse listen yourself.
Maybe you can hear the IM on 21410 kHz to report to your national
telecoms. authorities. Pse listen also to the attached file. Tnx.
Right at the end, there may have been something to identify the content,
but it was covered up by some noise that I am sure once Uli makes up a
cable for his new radio, he will not have to make recordings by what
sounds like acoustic coupling any more. ;^)
I can find no recent cluster spots of this intermod & no mention on the R1
MS logger, so maybe few know to even look for it.
Perhaps to protect us from somebody's incessant & unwanted propaganda, my
country is being thorough & now also targets potential intermods (0300-
0600 UT both 21550 & 21690 kHz are VoA from notoriously filthy Tinang in
DU; 0600-0700 UT on 21690 kHz they continue from A6-land - both intended
for reception here).
We here would be most grateful to help, should where this jamming signal
is coming from be narrowed down a bit more, and try to get word through to
them of a whole bunch of actual VoA intermods we also need to be protected
from.
Happy China National Day to you all!
