Confusion... this band is apparently too wide for us ;-))

Clemens mentioned interference on 475.2 - 475.8 kHz.
I pointed out the Hell signal which is really on 476.2 - 476.9 kHz.
 Stefan's reply refered to the four unstable carriers between 474.2 - 474.5 kHz. It is indeed remarkable that what looks like SMPS QRM is being carried that far - the source must be connected to some large "antenna".

Alll the best,

Indeed! :-)
But the chirpy signal between 474.2...474.6 is actually QRM. It is there since years and also visible on the DL3ZID grabber in noth DL, a few 100km distant.

I like the signal from DL6TY :-)

Hi Clemens,

HELL from DL6TY?

Hello MWers!

I see and hear a strange noisy broad signal sweeping between about 475,2 and 475.6kHz.
On the waterfall it looks like a jamming signal from a SPSU.
But I can see and hear it also on the remote perseus in Amberg.
So it can't be loacal.
Maybe someone can take a bearing?
