Re: [HCDX] [dxld] Ron's logs
re VOV-1 spurious signals on 7196.25 and 7223.75 kHz of
Daclac / Dak Lak - Buon Me Thuot' site.
previously reported by Y.T. in June 2014 and Febr 2015 in bcdx:
VIETNAM 6020.0 Voice of Vietnam's 4th domestic program, non-direction
outlet from Daclac tx site, S=9+25dB or -55dBm signal in eastern Thailand
post. Boring endless female reading at 2321 UT, no music heard at all.
[Thailand location, selected SDR options, span 12.5 kHz RBW 15.3 Hertz]
(wb, wwdxc BC-DX TopNews Febr 21/24, 2015)
6033.400 Odd Frequency, some Himalayan/Myanmar/Laos/Thailand/
SoEaAsian area - music sound hill people singer heard. Could that be
Thimpu Bhutan so early at 2320 UT ?
In 2300-2400 UT slot, not heard after 0000 UT anymore. Or is this an unknown
spurious outlet and needs further investigation...
At 2349 UT on Febr 23 some 10 Hertz downwards now on 6033.390 kHz, little
scratchy audio sound, like SoEaAsian jungle or mountain forest tribe
people radio program, S=5 fade-out ...
[Thailand location, selected SDR options, span 12.5 kHz RBW 15.3 Hertz]
[later] So, the 6033.4 kHz UNIDENTIFIED mysterious spurious signal seems
in the clearing now ...
Most probably two symmetric spurious audio signals some
Â13.400 ... x.390 kHz/Hz frequency away distance ...
of fundamental Daclac / Dak Lak - Buon Me Thuot' site transmitter
installation in Vietnam.
Observed on both domestic Vietnamese 4th service on
6020 kHz and 1st sce on 7210 kHz program outlets these days.
That seems their very special - accurate - footprint ...
similar item we published in BC-DX TopNews June 2014 already:
7210.000 Voice of Vietnam 1st domestic px from 'Daclac / Dak Lak - Buon
Me Thuot' site scheduled 2145-1700 UT, at 1100 UT June 8 - 2014,
S=9 or -73dBm heard on remote SDR unit in southern Brisbane Australia. But
also the Dak Lak(Daclac) station produced two wider spurious signals of 4
kHz wide bandwidth each, 13.69 kHz distance apart on 7196.305 and 7223.685
kHz.
[some Febr 23 2245 UT / Febr 24 0015 UT morning log of remote eastern
Thailand post at Tha Mai location on Uwe's SDR unit place...]
(wb, wwdxc BC-DX TopNews Febr 24, 2015)
Uwe send me this e-mail now:
Ich habe eine mir unbekannte Station auf 6033 kHz gehoert, nicht
einordenbar,
... Ich tippe auf Ober-/Unterwellen von VoV Daclac auf 6020 kHz. Es ist
wie ein Fingerabdruck der installierten Sender in Daclac zu sein, gleiches
Phaenomen auch auf 7210 kHz, siehe Hardcopy. Beide Sender strahlen ein
Signal Â13.6 kHz aus.

re MYANMAR. 7200.09, Myanmar Radio
MYANMAR Only two strings visible on 9590 and 9730 kHz at 0430 UT Dec 30:
Nothing heard in Japan remote units at this hour.
Accurate 9589.991 kHz and on 9730 kHz strings visible, but latter disturbed
by powerhouse VoKorea in En at 0430-0527 UT at S=9+15dB strength level.
Latter carried soldiers chorus til 0438 UT, followed by news in En at
0439 UT, about North Korean fishery fleet workers. Improving of peoples
living conditions, leader Kim Jong-Un told the people about the 'fishery
front' to reach the successful 7th congress next year.

MYANMAR. 7200.09, Myanmar Radio, 1300-1312*, Dec 28. In
vernacular; pop songs; slowly improving till suddenly off.
Reception contingent upon both RTI and CNR1 (jamming) going off
together at 1300, but recently one or the other has often run late.

VIETNAM. Thanks very much to Hiroyuki Komatsubara (Japan) for
clearing up an UNID reception I was having on a good number of days
in Nov after 1300 (after CNR1 & RTI signed off on 7200). Heard an
UNID open carrier on 7196.25, but never was able to pull in any audio.
Finally gave up on it, as it was just too weak to tell anything about it.
Now I know from Hiroyuki that I probably heard a VOV-1 spur being
generated from their 7210 frequency. He believes that he heard VOV1
spurs on 7196.25 and 7223.75. This makes sense to me, as in the past
(as recently as June of this year) I often heard, with fairly good audio,
Voice of Vietnam-1 spurs on both 5967.0 & 5983.0, from their 5975
frequency, but have not heard those for many months now. Interesting
to now find out about 7196.25 and 7223.75.
