Regardless, Kriss, at this point either he posts pictures or gets no help. And if he is using sdrsharp, going over to the "airspy" group on groups.io would be his best bet. I'd missed the reference to sdrsharp in his message. Sorry 'bout that. I think I simply presumed he was using both SDRC and SDRSharp or something. If he is using SDRSharp he may be facing an image mixing response in his TecSun. There is almost no way it could not be there with the other signals normally present as expected. He may have found some bad gain settings and the 105.4 signal buried. Um, I am presuming he is not in the US. There is no (legal) signal on 105.4 MHz anywhere in the US or Canada (or Mexico).

OK, 105.4 MHz in Britain is a digital station. SDRSharp and SDRC both will not process the digital modulation and provide audio. Case closed.

Joanne, there are no digital radio stations in the UK in the regular VHF FM band 88 to 108 MHz.

All digital radio broadcasting on the UK "DAB" digital system takes place in Band 3, 174MHz to 240MHz.

105.40 MHz is used by several analogue FM stations here in the UK.

Yes, had I read the topic properly I would have suggested it was a matter of getting the RTL gain correct.

I seem to remember that too much or too little could result in no reception with these devices.

This is from Wikipedia. I stopped reading at the first sentence.

Regardless, I'm not addressing this topic again until I see proper images of what the complainant is seeing.
