Thank you very much for your information.
I checked my winradio DDC file to see the frequency.
Surprisingly, V28 was on that frequency at 1341UTC.
Below is my recording.

At this time, what do you think V28 is coming from?
Most Korean dxers think V28 is transmitted from North Korea army.
My recordings also show V28 on that frequency at that time, that is why I suggested you look on that frequency for it. Because the signal is very weak here I am less likely to catch new frequency usage than anyone in Asia, but I still try to look.
The 3116.88 kHz frequency came on the air after 3689.8 kHz finished their messages, so it is possible that transmitter was retasked after completion at 1339 UTC. There were 4 frequencies used in total that I can find on Dec 16, 3054.65 kHz (1332 to 1342 UTC), 3116.88 kHz (1339 to 1342 UTC), 3276.87 kHz (1330 to 1340 UTC), and 3689.8 kHz (1330 to 1339 UTC). So 4 frequencies, but never more than 3 signals on the air at one time, and I have seen this activity several days.
I have no proof as to where V28 is coming from. It is too far away from me for my receive bearings to be of any real use to determine source other than in the general area of the Korean peninsula. However I tend to believe it is from North Korea. As time goes on I am less sure it is a traditional spy numbers station though.
Look at the activities. 3277 kHz is normally on frequency +/- 0.2 kHz, so that is pretty good, but the other frequencies are all over the place, and seldom the same frequency 2 days in a row. In the around 3055 kHz region the frequencies used have been 3039.17, 3047, 3054.85, 3063.75, (all of these freqs are approximate, there have been large variations) with no real cycle seen to date, just every day is on a different frequency. In the 3690 kHz region the frequencies seen have been, 3687 3689, 3690, 3691, 3692, 3694, and 3699 kHz (all of these freqs are approximate, there have been large variations).
With such day to day frequency excursions with no apparent defined cycle, unless the next days frequency is part of the proceeding days message it would be hard for an operative to make sure they get the message each day. And this is poor trade-craft because if the person listening misses one day they essentially become "lost", and must find the message by just tuning around.
With one frequency always being usably close to the same frequency and all the others varying across wide ranges I have to wonder if only one source has any real meaning, the 3277 kHz source. Also with the pauses, mistakes, drop outs, etc, seen on the other frequencies, along with the frequency variations, I almost wonder if those other freqs are for training purposes?
Also, this station feels rather like the Chinese VC03 / 05 and related stations, possibly less "spy" and more military oriented, maybe military training oriented.
Of course that is just speculation on my part.
T!
