Checking at 20:30 UTC, and 549 is no longer carrying the super power Ukrainian Radio. I can still hear them on 873 at fair/good level with President Zelensky speaking at 20:49, cochannel to a Quran station. I hear no other Ukrainian transmitters on MW (via Hungarian SDR).

Here in Finland I can hear UR also on 657 (strong, but QRM) and 1404 kHz (weak) with QRM and Armiya FM 809.4v kHz.
