(CRN) CNR Interference with Voice of Mongolia

When listening to 12,085 kHz shortwave this morning*), some time after 10:30 Greenwich Mean Time, I initially thought that the Voice of Mongolia (VoM) had expanded its broadcast in Chinese at 10:00 hours GMT, from thirty to sixty minutes. In fact, it was China National Radio (CNR) on shortwave which obliterated the Voice of Mongolia’s half-hour broadcast in English, which starts at 10:30 GMT.

When trying to listen to Taiwanese shortwave stations, I usually happen on CNR, too – they seem to “accidentally” broadcast on the same frequencies, and the reason may be – just my guess – that they consider this somewhat more “polite” than the outright jamming that occurs on the frequencies used by stations like Sound of Hope (Xiwang zhi Sheng), or the BBC, or the Voice of America. After all, relations with Taiwan have “warmed”, according to Beijing’s, Ma Ying-jeou’s, and many international news agencies. Fighting harmful information from Taiwan with the “firedrake” may therefore be deemed inappropriate by Beijing’s protocol. The protocol doesn’t count however when it’s Sound of Hope which broadcasts from Taiwan. The Voice of Hope broadcasting site appears to be Tamsui (aka Tanshui).

But it is hard to tell if the CNR broadcast on 12,085 kHz, interfering with the VoM, is really intentional jamming. VoM’s Chinese-language broadcast which precedes the English program (and which I also listened to) apparently wasn’t impaired by Chinese broadcasts this morning, at least not in the beginning.

Either way, Mr Soumya, a YouTube user, is angry. Voice of Mongolia’s English language transmission blocked by strong QRM from China Narional Radio (CNR1) August 2012 1040UTC+, he wrote on Monday, and: Curse the Chinese!!

That said, he uses a Tecsun receiver.

I searched for “Voice of Mongolia” and “jamming” once I noticed that what I heard after 10:30 wasn’t really the Voice of Mongolia anymore.

Anyway, dear reader: next time you listen to China Radio International (CRI) – on shortwave or on FM from your local provider – spend a moment on thinking of those whose broadcasters you are allowed to hear, but who won’t be allowed to listen to your country’s broadcasts.



*) India seems to be a much better location to listen to the Voice of Mongolia’s GMT-“morning” broadcasts, than Northern Germany. You can find my own recordings of the broadcasts here (10:00 GMT) and here (10:50 GMT).
