Anyone ever have a 2970 DX lose amplification out the speaker? Seems to
have good audio still when you transmit but no receive audio out internal
speaker or external speaker. Microphone has been checked and is ok. I can
here it but its like its not being amplified just very low level.

How this happened: I was connecting the radio up to power and my external
speaker was grounded and it seems the radio ground through that.
