[Elecraft] K3 MON feedback question

[KD3TB]

I found a similar problem and would like to add my "2 cents" for a future
firmware update. 

Currently the Mic+Lin (Menu) setting is either on or off. I would like to
see an additional option that mutes the Lin In audio, when audio is picked
up on the Mic Input. This would prevent audio feedback from getting into the
TX signal (and Monitor audio)from the Lin-In when using the Mic to transmit.
To date, no one has said that this "noise audio" is being transmitted on my
signal. I do find that when recording a message in the K3 DVK, the audio
from Lin In will bleed over into the recorded message.  

Thanks,  Irwin KD3TB
