LF: Re: Unknown signal

[André Guyé <andre.guye1@aliceadsl.fr>]

Hello friends. Just an idea :

 

Listen on CW. If you copy “BIA”, that is the Poland NDB in locator KO10BC. It is transmitting on 473 kHz with + / – about 1 kHz double modulation.

Hello Dave!

Thanks for your piece of information. Now, I have switched my RX on and the strange signal is on the band again. Hmmm. It must be really big TX, because the signal is  audible across The Europe.

I can hear it here also. It's not local to me - it exhibits slow QSB. It might be a defective Navtex TX.

Same signal here in JO42, quite strong but with the usual QSB.
Sounds a bit like a PSK 'idle' signal, but distorted. Or RTTY.

Hello Friends!

There is a strange signal on 473.9kHz - see the capture:

 

 

 

I can see the signal on Stefan´s MW grabber as well. Any idea about this one?
