Firedrake 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.

Example frequencies

These frequencies are in kHz and were logged by HF Underground users. Those wishing to hear Firedrake should try scanning around these frequencies or tuning to scheduled broadcasts known to be jammed rather than only checking specific frequencies.
