Question to Mike, KK7ER:

What is the DigiKey p/n for the PCM1804?

Same here, Dick.

I even took the rig outside just to be sure I was not picking up something in the house.

The new PCM1804 just arrived from Digikey.

And my rev 1 QCX Mini taught me how to replace SMD audio op amps of similar size.

Hopefully, this one will go more smoothly than that (where I ended up lifting a PCB trace in the process)!
