KOREA SOUTH. 4900, Korean Numbers Station V24, 1531-1545* UTC, on Feb 25.
Mixing with Voice of Strait (China) also on frequency; started out with both
stations with singing; at 1535, V24 went to numbers in Korean; both equal
strength. My audio at http://goo.gl/PdOxaY .

This Chinese station started using this freq, 4900 kHz, on 3 February. V24 has used the freq on 23 and 25 February, as per their habits before that. They will also probably use it at 1530 on 27 February.
Both stations are about equal strength here also, and it can be tough to pull V24 out. I can tell it is there, reciting its numbers, but not really what is being said. But, the V24 carrier is slightly below the BC station, the two stations are about 19 Hz apart, so you can look closely and see both transmitters online, even when you can't make out the audio clearly.

I was able to copy 4900 today, 2/27 at 1530 on 4900 via a South Korean SDR on globaltuners, but it was rough with Voice of Strait overwhelming it. The SDR may not be helped by its proximity to V24's Tx, which might have placed it at the fringes of the skip zone. I forget how far away the operator told me he was from Seoul, but it wasn't all that far.
