11:41 nothing here

1153 trying on Weston SDR : bursts of signal, that's a 3rd order intermodulation,
so find (2*F1 - F2)=6975, with strong signals on F1 and F2

edit : could be also a 2nd order intermod, formula F1+F2 or F1-F2

Weston does suffer from strong signals from the Washford tx site on the Somerset coast - there are a number of mixes I am aware of (like 6363) - but not sure about this one.  Some of those mixes also cause the Kiwi SDR to block. I've seen that happen on the 48mb quite a lot.

These mixes usually present themselves as BBC programming, but I do check for that to make sure the audio isn't the same.

I live close to Droitwich and we have similar problems caused by 198 / 693 / 1053 / 1215 etc...

Others on the chat heard it in Germany - so I'm happy to stick with the UNID.
