Re: Stopband Critical and Attenuator Fail Notifications
Yes, I did more than once. Tests still fail. Based on what I have seen while researching, I think I have somehow damaged at least part of the attenuator circuit. Don't know how, but if it is that

Re: Stopband Critical and Attenuator Fail Notifications
Something I just tried changed the results. I did a factory reset and then set the frequency range to 100 - 150 MHz and reran the test. Only Test 12 Attenuator failed.

Indeed, you only need to update tinySA-App.exe and you can keep the current tinySA-App.ini
No other files are needed.
