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.
