WEBSDRSWL: China jamming Radio Free Asia with Firedrake

SIO of jammer 533

SIO of radio Free Asia is 522

Firedrake (sometimes labeled as "Firedragon") is the unofficial name of a shortwave broadcast containing loud oriental orchestral music. It exists solely to jam other broadcasts on the same frequency, apparently for censorship. Firedrake broadcasts only contain music; no form of on-air identification has ever been reported. An article on satdirectory.com revealed that the source of the Firedrake shortwave transmissions is a China National Radio satellite feed.

Targeted broadcasts

Firedrake has been logged on frequencies used by Radio Free Asia and Sound of Hope. The jammer is typically used against broadcasts in Chinese targeted to Asia.
