Re: [IRCA] 1566-China (Yanbian Jammer) Information

To make a long thread even longer, here's an article about the Yanbian "jammers" that circulated last spring. English translation originally posted by Alan Davies on DXLD and elsewhere. Unfortunately, the translation is a bit imprecise, like most Chinese to English translations. I'm not sure how effective a 25 kw transmitter would be against the powerhouses on 1053, 1188, and 1566. 1053, at least, is not new - I've had it listed in the PAL for over a decade.
"Medium wave transmitting station room source transformation. Source: "Technology Wind" in 2015 the first 04 Author: Zhang Ziming;
"Our medium wave transmitter station site is located in the town of Yanji city Xingan village Yilan. Signal source used as a main one two. The main road is an optical fiber (special road), prepare the way microwave analog signal. With the rapid development of urban construction, urban scale continues to expand, the location of the launch pad from the past into the suburbs of the city of Yanji city, the buildings gradually being under siege. This makes the old launch pad of the emitted electromagnetic waves, surrounding buildings can easily be blocked, absorbed, there has been transmitting antenna ground network seriously damaged, transmitter will not turn, transmit power reduction, listening effect of variation, reduced coverage and multiple broadcast barriers.
"So we moved to a new station in 2009, the new station located in Longjing Town Dongsheng Bay Village. After we moved to a new launch pad Taiwan, a total of four sets of radio programs, which use 200 kilowatts produced American Harris DX200 transmitters 1, a frequency of 1206 kHz, the Yanbian Korean, and broadcast program. Shanghai Pearl producing 25 kilowatts TSD-25 transmitter three, frequencies of 1053 kHz, 1188 kHz, 1566 kHz, 1053 kHz which TSD-25 transmitter to broadcast Chinese Yanbian program; 
1188 kHz, 1566 kHz TSD-25 transmitter for the jammer.
"In order to achieve the "high-quality, uninterrupted, that is, economic, and security," the general policy requirements and effectively protect the safety of high-quality broadcast, each transmitter must be equipped with two-way power, but each has at least two signal transmitters Source is also unquestionable. MW new station located in Longjing Town Dongsheng Bay Village . . "

so naturally it would be parallel to Yanbian PBS 1053.
I take it that in this case "jamming" means "powerful interfering
broadcast" rather than "noise transmission".

Possibly 1053-Yanbian PBS was the Chinese station mixing with the Korean Jammer at a good level during the Cape Perpetua DXpedition in August last year. Maybe a breakthrough case of a Jammer jamming the Jammer? https://app.box.com/s/nvld5g2vhup50hdau3u01wfl0qycdono Gary

Indeed it does Chuck.

As you  were replying  to Gary's e-mail that contained the sentence


It does not use a noise jammer like the 1053 station in Korea.

I jumped to the conclusion that is what you had been referring
to.   If I didn't jump to conclusions, I'd hardly get any exercise at
all, so you'll have to bear with me, I'm afraid.

I wonder which station on 1053 would be parallel Chuck?   It seems a
little odd that China would rebroadcast what is supposed to be a
jammer in South Korea.

Mauno,

The Yanbian-1566 Chinese station has always used the PBS

programming in an obvious attempt to block the reception of HLAZ in
China, a practice which Bill W. says is also frequently done by
China in attempts to block VOA and other stations it doesn't want
its people to receive. It does not use a noise jammer like the 1053
station in Korea.

Are we talking now about noise jamming or Yanbian PBS programming?

It hasn't shown up for me at home either, Nick, but it was

pretty obvious during a trip to Ocean Shores, WA last April (in
female Chinese, under HLAZ's male Japanese). By coincidence, this
was apparently the first week that the 1566 Chinese HLAZ Jammer
started to broadcast, according to Hiroyuki Okamura of Yokosuka, Japan.

Thanks for that information.   I was wondering about the jammer
while in Masset in October.  I did not hear it, and was expecting to
hear it, so I guess it was likely off the air during my visit (in
mid-October). 73,...Walt
