Think about it, grasshopper. The receive circuits ("scratchy reception")
and transmit circuits (no transmission & loss of sidetone) are completely
separated in the audio panel.

What is the ONLY element in the chain common to both transmit and receive?
Do the words antenna/feedline strike a familiar note?

Okay, so it's not the radio..... ??? I took off with the TKM,
yesterday morning, and it failed within 20 minutes! Same symptoms!
Reception started to get scratchy, then no transmission with a loss of
side-tone...

I'm not sure if it makes sense to isolate the audio panel from the
radio, since we have confirmed that the radio works in another plane
and a working radio does not work in my plane???
