I was continuing to investigate why I was having such poor result on my UHF station and noticed that my NooELEC SMArt was hot…very hot when it was plugged into my pc. After restarting it had a nice spike right in the centre of the frequency display so I have come to the conclusion its a bit knackered.
I was going to buy a replacement as they are pretty cheap and had thought about an Airspy mini but remembered some older conversations about the RPI not managing to to keep up with the sample rate. I did notice on their website that they support RPi .
Does anyone know if the issue has gone away?
