[arm-allstar] UV-82 No audio/DTMF input

Fri Jul 12 00:04:53 EDT 2019

  Doug,

  Yeah, I dont understand this one either. Everything is working as 
it should without the 2N7000 with COSFROM=USB. I was watching 
simple-tune option V while listening to stations and PTT shows 
'KEYED' when people talk and goes back to CLEAR when they stop. When 
I talk, COS goes from CLEAR to KEYED and back to CLEAR when I am done.

  I talked to a couple different people for an audio check and both 
said audio levels sound fine.

  This has been a strange one to say the least.
