Thanks for your comments and information, Chris!
<<< In addition to the TOH IDs at :30 (obviously because the DPRK is a
half-hour time zone a half hour behind South Korea), they usually air a
half-hour ID as well, with significant period of silence before the station ID,
though no time pips. >>>
That's interesting. After multiple recordings of 657 here at home I was aware
of the 3+1 time pips and ID's on the half hour, but not the ID's at the top of
the hour. Of course it might be helpful to know some Korean in order to
recognize the ID's :-)
<<< Your reception is better than heard in South Korea due to the lack of
jammers that are quite the pest. 621 was always a pretty hard catch for me with
the South Korean jammer (which was of the silence/slight buzz type). The
transmitter of that station has never been good anyway, but it was also further
up the coast too and likely aimed at Japan since it plays Japanese programming
early in the daytime. >>>
The 621 transmitter did have a buzzing sound similar to 60 cycle hum, but a
pretty potent signal on most nights. Since I understand conversational Japanese
it seemed to me like the announcers were pretty robotic. I never noticed any
jammer on the frequency, but 621 was a real zoo in Kona, with the exotic Radio
Tuvalu holding the frequency until around 0800, when NHK1, China and the Voice
of Korea would derail it, and fight it out among themselves.
<<< And 801 was broadcasting on 802-805 for the longest time to avoid the
South Korean jammer, not to mention it was drifting, as can be seen on the SDR
images I had previously posted of it. I am surprised of the jammer you posted
on there. Either the power has been boosted, or this proves that it really is a
powerful jammer, which I hadn't expected. You're hearing the jammer in
Hwaseong. >>>
Thanks. The 801 jammer showed up about half of the time, in an irregular
pattern. Although the audio format was similar to the old 1053 beehive, there
were pauses in between the beehive audio, and sometimes the "bees" took a
break, or went QRT. I also noticed an 819 jammer similar to a video game
zapper, but it never had the power to seriously challenge the monster KCBS
signal.
<<< And for your logs, please note your typo on 819. This is the flagship
station of the KCBS network, not Pyongyang BS. >>>
Yes, I know that now. I'm not surprised that it is the KCBS "flagship," since
only a handful of other TP signals were in the same league (the NHK2 stations
on 747 and 774, and 981-CNR1).
