Hi Evan,
I created a small test amplifier on a breadboard to test the uBitx LM386 in isolation.
It still works fine. It was an interesting learning experience to build this test circuit:

With or without antenna I can not hear anything other than noise and a slight clicking
noise when I tune to different frequencies. I can increase/decrease the volume of the
noise with the volume potentiometer.
This probably means the RX problem is located somewhere before the audio amplifier.
I did find a 'uBitx diagnostic guide' (written for the uBitx v3, is there a version for the
uBitx v5?). I will try to determine how much of this guide is still applicable to the uBitx v5:
