Sure.

I have a TV HAT attached to my Pi picking up Sutton Coldfield perfectly. Do you know your transmitter?

I got it working!
The premade muxes are outdated so I had to google a lot to find the right settings for my area!

Hi Phil,

I am only able to find 7 channels - can you point me in the right direction to where you found the info requuired and how to set up? I am a complete noob to all this... Tnx.

Which city are you in? I have the same gear (RPi3 + uHat) and have been desperataly trying to scan channels from the Stockholm-Nacka transceiver. Occasionally I have managed to get channels for Teracom Mux 1 (490 MHz), e.g. SVT1, SVT2, etc.

So far though, I haven't been able to stream anything from those channels. Today I exchanged my RPi2 for a RPi3, but now I get only failed scan from the 490 MHz band.

Any ideas?

Turned out to be a faulty antenna cable.
