[HCDX] BBC Uzbek Dushanbe 4790 kHz 1300-1330 UT, Dec 13
TAJIKISTAN / CHINA Mainland
4790 kHz Jamming against BBC Uzbek via Dushanbe Yangi Yul
{4789.988 accurate} 1300-1330 UT on Dec 13.
Chinese security authority is much flexible, instead of China Opera mx
jamming, today Dec 13 came a WHITE NOISE interference on air, while jamming
the transmission in 60 meterband.
I heard in Karelia-Finland in Mauno's 8014port SDR.
And in St.P. and Moscow Russia:
log
Usual 4790 kHz TJK was 13 to 17 minutes earlier to warm up ON AIR already.
After my Tune-In I heard at 12.59:08 UT to 12.59: 37 UT the known
BBC / Babcock Control Room Cello / String Pause Music feed line filler from
Dushanbe Yangi Yul TJK, an S=9+10dB signal in Finland.
13.00:03 UT local Uzbek string instrument,
13.00:23 UT the station ID by a female voice.
Nothing heard of usual BBC Big Ben tower chime etc.
At 13.02:05 UT China put a strong NOISE jamming on air, BROADBAND WHITE
NOISE and metallic audio sound, as wideband around 8 kHz bandwidth.
The end of the BBC Uzbek broadcast was heard at 13.25:55 UT, a local string
instrument play, followed by the BBC / Babcock Control Room pause music
again, with cello / string instrument piece from 13.29:38 UT, this last
until 13.30:57 UT.
TX Dushanbe Yangi Yul transmitter carrier string switch connection O F F
at 13.31:07 UT.
The CHINA Noise Jammer remained until 13.32:55 UT in the air.
The 8 kHz bandwidth noise signal disappeared from SDR screen.
The other three BBC Uzbek broadcasts at 1300-1330 UT:
most 13865 kHz signal was disrupted, with a CNR word and 'Radio Play'
program, no music jamming observed on Dec 13.
S=9+30dB signal here in Europe.
But had the BBC Uzbek program on 15510 and 17780 kHz on top, little China
jamming here with us in Europe, but could be much worse and different in the
Uzbek / Uighur language target area in western China.
wb
ps.
Tajik R1 Dushanbe on 4765 kHz is on the same power strength level at this
time.

re 17650 BBC Uzbek on website ??
Specifying 17650 kHz on the BBC website is not correct, but possibly part of
the VEIL behaviour or coming BBC frequency hopping aim to escape the Chinese
jamming.
In my estimation, Uzbek is not necessarily one of the various 65 Chinese
state national languages,
such as Tibetan and/or Uighur in western China location, the latter are for
years target of China Mainland radio broadcast jamming.
Uzbek as Turkic group language, but is determined by Chinese security
authority with this
Understood the background for jamming purpose.
Otherwise the security authorities would in giant empire not jam these short
30 minutes service.
If there would be no connection, otherwise the security authorities would
not jam these short 30 minutes service in giant empire.

Re China Mainland Jamming gegen BBC Uzbek 1300-1330 UT Dec 12 !?
Dushanbe MW 1251 kHz
Dushanbe4790 kHz
Oman 13865 u. 17780 kHz
Thailand 15510 kHz.
Today Dec 12 I had no Chinese Opera jamming, but the BBC Uzbek program Yangi
Yul 4789.988 kHz and also on the \\ 15510 kHz Thailand Nakhon Sawan relay
site S=9+30dB, and the BBC Oman relays 13865 S = 9 + 40, and weak on 17780
kHz also.
We had to talk with Mauno and Glenn in November about Chinese jamming
discussed programs against the BBC Uzbek, but later no longer persecuted.
The Jamming on 15510 kHz is also weaker than on 13865 and 17780 kHz.

[HCDX] BBC Uzbek now started in 4790 kHz
New frequency started in Tropical Wave - connected on 4790 kHz BBC World Service now started in 4790 kHz (100 kW power) BBC Uzbek .

I imagine it's quite a bigsig into neighboring Uzbekistan, but why don't the ChiCom jam it? It's only 307 km 191 miles from Dushanbe to Tashkent, unless you're driving: 423 km/263 statutes. (Glenn Hauser-OK-USA, dxld Oct 14) 4790-, Oct 11 at 1309 UT, very poor signal with talk, presumed BBC Uzbek relay. No ChiCom jamming reported anywhere I've seen, so maybe this tactic is working. Over here, CODAR is the enemy.

This 4790 kHz TJK transmission IS NOT registration requested in ITU / HFCC list in A-15 and/or B-15 lists, maybe is a VEILED target service towards Kashgar western China area?
