CLE FIN1:n aikaan kuulimme kolleegan kanssa tunnistamattoman aseman CSO 520kHz. Se kuului kohtuullisesti miniwhipeillä, mutta melko huonosti lännen suuntaan olevalla 500m langalla.
Oli kuultavissa kahtena iltana peräkkäin, sen jälkeen ei mitään. Kukaan muu ei ollut sitä aikaisemmin raportoinut, kunnes nyt on alkanut tapahtua:

Still on air (1923z). At 520.403 with a fair signal and 1 in 7".
I have never seen it before. LSB surely covered by NAVTEX.

Hearing CSO-520 here, on 519.600 / 520.400 with 2s gaps. Signal rather prone
to deep fading at present 2000 utc. Can't get a decent bearing at this time.
Will keep a watch on channel.

UNID CSO-520 is audible here as well at 21:10 UTC
It suffers from fading quite a bit, so I think is not very close.
My guess is around 800 - 1000 km
It certainly is coming from the north.
My "static fighter" is on and eliminates the static from the south.
Maybe I can make a bearing when the static is a bit less.
It is very bad tonight.

CSO-520 – the loop seems to indicate the nulls are around NW/SE roughly so best direction seems NE/SW
But fading doesn’t help the check too much. Certainly don’t think it will be a daytimer here – will check tomorrow.
Fairly good signal at 2127utc.
