On Mondaqy, the BBC accused China of jamming its
Mandarin English-language service on shortwave. However, it also added that it wasn’t poossible to determine exactly where the blocking was coming from. Not at “this stage”, anyway.
On Tuesday, a foreign ministry spokesperson claimed not to understand the situation, and a media commenter, Michael Anti, apparently presented himself as a nerd (quoted by The Guardian):
I doubt there is anyone listening to the BBC English radio in China.
Anti should know better – there are even Chinese online discussions about foreign broadcasters on shortwave. Not to mention that only every second Chinese citizen is a regluar internet user so far.
Update / Correction (Febr 26, 2013):
the BBC statement is about jamming of its shortwave programs in English.
The following is a recording of a Falun-Gong-leaning station, the Sound of Hope (希望之声) being jammed.
You can hear the jamming station’s output rise after 35 seconds into the recording, and the “alternative” program, Chinese folk music known as “Firedrake” (火龙干扰) sets in after one minute. (Recorded in June, 2011.)
It appears that regular Chinese domestic programs on shortwave are also at times used to interfere with undesired foreign broadcasters, as they go on air along with them, and off air once the undesired broadcasts are over.
That’s a lot of time and effort for nothing, if nobody in China actually listens.
