I suggest you shut down the Raspberry Pi using the shutdown menu option on the home screen.
Hi Evan. Thanks for the reply. I booted the board a lot in the last 24 hours and I don't thinks its the WM8731 because I can see noise and intermodulation artefacts in the scope and waterfall. But nothing else. That should be an indication that at least the audio converter part is working??? ( Maybe :-) ) ?But the receiving part seems to be completely deaf. I started to probe the RX signal path and it seems that anything before J7 is dead. If I probe J7 I get at least an increase in noise level. My problem is that I am not used to debug HF electronics so it's hard for me to make an educated guess where the problem might be. Any help is greatly appreciated. Cheers.
