Someone hit the "emergency stop" switch by accident ;-) But at least 20m seems to be slowly recovering now ...

I have never seen this before. See attachment. This is also an opportunity to look at PLC interference at the lower bands, which is normally covered by signals. I checked it on 3 different antennas: mini-whip, loop and hf-doublet. 73, Roelof, pa0rdt Middelburg, JO11tm
