If this has been posted before, forgive me for the bandwidth.
The following is excerpted from the ARRL letter:
As the so-called "Firedragon" jammer continues to transmit in one or more
Amateur Radio bands, the International Amateur Radio Union (IARU) and three
of its Region 3 member-societies so far have appealed to the jammer's target
to move elsewhere. The Firedragon's all-music transmissions from the
People's Republic of China (PRC) appear aimed at blocking the much-weaker
broadcasts of the clandestine "Sound of Hope" (SOH), located outside the
PRC.[ .....] the SOH said its supporters use various avenues "including Amateur Radio
frequencies" to get their message into the PRC.
"Through our investigation, we learned that the transmissions of SOH
programs through Amateur Radio frequencies come from areas around China, and
they each only target a local area of China with very low power, only for
the intended audience and would interfere with nobody else," said SOH's Yue
Chen.

Wireless Institute of Australia (WIA) Director Glenn Dunstan, VK4DU, told
the Sound of Hope via e-mail this week that if it wants the support of the
international community, it should move its transmissions into legitimate
broadcasting spectrum.

Bihlmayer said September 6 that the Firedragon was back on 14.050 MHz -- a
part of the 20-meter band allocated to the Amateur Radio Service on an
exclusive basis worldwide -- after spending two days on 14.400 MHz. Over the
past several months, the jammer also has been heard on 10.135 MHz, 14.260
MHz, 18.080 MHz and 18.160 MHz.
The music jammer takes apparent monitoring breaks on the hour. When the
jammer's carrier is off, Bihlmayer, who lives in Southern Germany, says he's
heard a weak carrier on 14.050 MHz broadcasting a Chinese program that
included speech.
Note the use of 14050, and the breaks on the hour - just in time for Kevin to get the net started!
