I have recorded 621 kHz [PMR] from 2 until 9 AM last two nights to monitor just in case there would be changes, Radio 1 Plus was audible with old soviet schlager music and clear ID in the early morning. Very low audio and short digital drop outs. however, NO trace of TWRs program on this frequency before or after. Not even the very destinctive interval signal was heard there.
Obviously using VERY directional antenna pattern towards East – or they were just not on. Power of 621 is quite less then 1413/999. And feeder signal of Radio 1 Plus certainly via webstream.
