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

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

"In order to achieve the "high-quality, uninterrupted, that is,

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?

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
