I listened to 621 again this morning.   There are two carriers, the 
dominant one is a couple Hz high, the weaker is on about 620.94.   
Listening again, the music sounds more like what you'd hear on a 
Chinese, and not DPRK.  So this one is probably China.

The 621-VoK transmitter (used for NK's Japanese service) has a notorious buzz 
on its signal. This was its degraded audio last December in Kona, Hawaii, most 
obvious around the 45 second point

Thanks Gary,

I think the buzz might actually be the 40Hz "hum" from the offset in 
both our cases, as your "buzz" only shows up as the audio 
weakens.   So, perhaps not part of the distinctive programming, hi.

Nick

Hmm, interesting, Nick.

It seems like our Japanese friends also made some remarks about the buzzing hum 
of 621-VOK, though-- or maybe it was Chris Kadlec?

Re: [IRCA] Saturdays highlights - TP DX in Seattle

[Chris Kadlec]

Just wanted to chime in on this one. I never heard a buzz on the Chongjin 
transmitter. It's always been a clear signal, so it could be your tech stuff 
(of which you know everything about and I know nothing). It's been two years, 
but here's one of numerous recordings of 621 I have from 330 miles out. This 
one was taken atop a skyscraper in downtown Seoul; the signal is airing its 
nightly Pyongyang Broadcasting programming. Anything could have changed since, 
but generally, their signals have improved with time as they've dumped more 
resources into the broadcasting efforts or budgets. Unlike Pyongyang, which is 
100 miles to the north, and Haeju right across the water, 621 was pretty rare 
to hear by groundwave. The only stations of that distance that were typical 
were Fukuoka ones now and then. But VOK programming comes from the same 
transmitter.

Re: [IRCA] Saturdays highlights - TP DX in Seattle

[Nick Hall-Patch]

Excellent call Chuck.   Thank you!

In Victoria, 873 was pretty much a conflict between N. Korea and 
Japan, and 1341 shared the lack of excitement common throughout most 
of the upper band, but


900...definite parallel with 621 from 1358 to 1404UT, with music and 
talk, and the pips lining up nicely.  Actual ID, perhaps not so easy.


Amazing.   Both the strength on 621 and the fact that Heilongjiang 
RGD Xinwen Guangbo was heard at all on 900 kHz.


Thanks again.

Thanks also to Bruce Portzer for pointing me to the weak Vietnam 
chimes on 675, even though NHK1 was my dominant, and also to hunt 
more carefully for the Chinese pips on 810, in this case, under KGO.


That was the morning that was, for sure.

There are a mess of tones around 40 Hertz on your audio recording 
Gary, plus another around 45Hz.   Interesting that they should 
correspond to the offset of N. Korea on that channel.The Korean 
carrier itself may not be very cleanbut for the listener, it's 
not easy to determine what of a hum is due to offset  from the 
Chinese (or ?) on the same channel and what is due to audio that the 
station is broadcasting.


I figured however that when your Korean audio was strongest, the hum 
was weakest, which would seem to indicate that the hum wasn't part of 
the broadcast.

If you still have the recording Bruce, could you check the frequency

offset? The wall to wall ballads seemed to be pretty much spot on
the channel here, though there was also a carrier ~40Hz low, which
seems to be where DPRK resides. But if I set the BFO to demodulate a
signal 40Hz low, I got a buzz on the music, not a better signal. >>>

Excellent call Chuck.   Thank you!

In Victoria, 873 was pretty much a conflict between N. Korea and
Japan, and 1341 shared the lack of excitement common throughout most
of the upper band, but

900...definite parallel with 621 from 1358 to 1404UT, with music and
talk, and the pips lining up nicely.  Actual ID, perhaps not so easy.

Amazing.   Both the strength on 621 and the fact that Heilongjiang
RGD Xinwen Guangbo was heard at all on 900 kHz.

Thanks again.

Thanks also to Bruce Portzer for pointing me to the weak Vietnam
chimes on 675, even though NHK1 was my dominant, and also to hunt
more carefully for the Chinese pips on 810, in this case, under KGO.

That was the morning that was, for sure.

In my spectrogram, it's not a bunch of discreet tones but rather a "smeared"

the carrier suffers from jitter.

Re: [IRCA] Saturdays highlights - TP DX in Seattle

[Mauno Ritola]

Hopefully the spectrogram via a South Korean remote rx comes through via 
the other list. I think it is 2 Hz on the high side.


The carrier on the low side drifts quite a bit: between 620.95-.965 kHz. 
If it is one of the dozen Heilongjiang transmitters, it is on 24h. Acc. 
to WRTH they have programming until 1800.


North Korean signal quality and strength seems to vary a lot. It has an 
audio defect sounding like bubble jammer, when listened to in SSB. It 
seems to be on 24h. Today at 0930 the audio is very distorted.

Is the MW offset list at https://www.mwlist.org/mwoffset.php?khz=621 
no longer accurate then Mauno?


It's pretty clear that the N. Korean is on the low side in that 
list.  For me, the first clue that it was not N. Korea that was being 
heard was that the carrier on the low side was relatively weak 
compared to the dominant.

Nick, as you can see, most measurements are many years old.

It really looks like North Korea is the one on the low side. It drifts 
between 620.95-620.97 kHz and has no break between 2000-2100.


At least some Heilongjiang transmitters are on overnight, nearer nominal 
and carrying non-stop muzak.


Chuck, I meant, that all carriers were 2 Hz high due to no calibration.

Best regards,

Mauno

Is the MW offset list at https://www.mwlist.org/mwoffset.php?khz=621 
no longer accurate then Mauno?


It's pretty clear that the N. Korean is on the low side in that list.  
For me, the first clue that it was not N. Korea that was being heard 
was that the carrier on the low side was relatively weak compared to 
the dominant.


best wishes,

Nick

Hopefully the spectrogram via a South Korean remote rx comes through

The carrier on the low side drifts quite a bit: between 620.95-.965 
kHz. If it is one of the dozen Heilongjiang transmitters, it is on 
24h. Acc. to WRTH they have programming until 1800.


North Korean signal quality and strength seems to vary a lot. It has 
an audio defect sounding like bubble jammer, when listened to in SSB. 
It seems to be on 24h. Today at 0930 the audio is very distorted.

In my spectrogram, it's not a bunch of discreet tones but rather a 
"smeared" single tone as would be seen with a slightly unstable 
carrier. It looks like the carrier suffers from jitter.



I'd attach a picture of the spectrogram but then my post would get 
rejected..

There are a mess of tones around 40 Hertz on your audio recording
Gary, plus another around 45Hz.   Interesting that they should
correspond to the offset of N. Korea on that channel.    The Korean
carrier itself may not be very cleanbut for the listener, it's
not easy to determine what of a hum is due to offset  from the
Chinese (or ?) on the same channel and what is due to audio that the
station is broadcasting.

I figured however that when your Korean audio was strongest, the hum
was weakest, which would seem to indicate that the hum wasn't part of
the broadcast.

Hmm, interesting, Nick.

It seems like our Japanese friends also made some remarks about the
buzzing hum of 621-VOK, though-- or maybe it was Chris Kadlec?

Thanks Gary,

I think the buzz might actually be the 40Hz "hum" from the offset in
both our cases, as your "buzz" only shows up as the audio
weakens. So, perhaps not part of the distinctive programming, hi.

best wishes,

Nick

Nick and Bruce,

If you still have the recording Bruce, could you check the frequency

offset? The wall to wall ballads seemed to be pretty much spot on
the channel here, though there was also a carrier ~40Hz low, which
seems to be where DPRK resides. But if I set the BFO to 
demodulate a
signal 40Hz low, I got a buzz on the music, not a better signal.

The 621-VoK transmitter (used for NK's Japanese service) has a
notorious buzz on its signal. This was its degraded audio last
December in Kona, Hawaii, most obvious around the 45 second
point
