UA Suspilne movnik status update — several AM frequencies now in use.
Quick check upon the situation of Ukrainian Public Broadcaster – central program from last night (28 feb –> 1 mar) :

549 kHz good, especially strong after 21:00 CET
657 kHz fair, suffering from Rai which was active again last night after 1:00 although it was supposed to be off!
1404 kHz, strong but gets swamped out by RR Actualitati
873 kHz, vy. weak and only ID by compared with the others.
549 is running first, the others have a slight delay between 1 and 2 sec.

So I can confirm all four frequencies being on air!  (but 837 is off)
