Re: [IRCA] TP 23 Apr Victoria version

[Bill Whitacre <bw@xxxxxxx>]

On shortwave, Chinese jamming is a lot more sophisticated these days.  Gone are the days of loud rackets on shortwave caused by firedrake.  For quite awhile the Chinese have been merely âco-channelingâ with multiple transmitters and out-of-time [on purpose] transmissions to interfere with western broadcasts.  We poor western international broadcasters have taken so much âstuffâ off the air though that the Chinese have surplus facilities and for the past few years have been jamming [co-channeling] English from VOA, BBC and others.  Years and years of official complaining have had no effect and even direct negotiations during the early 90âs while working towards a[nother] âmost favored nationâ trade agreement led to naught when talks broke off immediately upon Clinton signing the MFN agreement.

When we âtestâ to see how serious the Chinese are about jamming a particular frequency used for Mandarin or Tibetan by moving the new frequency is found and jammed within 4 minutes.  Thatâs one helluva of a monitoring network and rivals what the Russians could do in the depth of the cold war.

Beijing is also known to âgo afterâ some religious broadcasters and as Gary points out they are notoriously paranoid about any âmovementâ that puts anything above âthe State.â

Mauno Ritola also heard the 1566 Chinese signal via a remote Perseus receiver in Japan, and thought that the new Chinese station's power should at least be 100 kW. By coincidence, I was in Ocean Shores, WA during that week for a 2 day trip, and noticed the new Chinese station interfering with HLAZ's Japanese service signal at times

>> As for the identity of the powerful new Chinese station and the bizarre choice of 1566 kHz as its frequency (which is one of the most "occupied" frequencies in east Asia, with HLAZ's 250 kW transmitter), there are differences of opinion. HLAZ broadcasts Chinese Christian programs in Mandarin to China, which the Beijing government probably doesn't feel very happy about.
