The Kalundborg LW transmitter on 243 kHz:
“Signal was on-off here permanently, on irregular basis. Observation on Sunday, Jan. 30th around 18:10 CET. Radiation power seems to be reduced as well, usually this is booming in here at the Baltic Sea (I can even catch Kalundborg FM transmitters some time). Disappointing signal strengh this afternoon, and many drop outs.”
Two other observations from Sweden and Denmark tell the same story.

A severe storm passed the country from Saturday till Sunday noon and it could have caused some problems. The storm may have put a fine layer of salt over the power supply components (just my guess).
