This is strictly firmware, and can be changed.

RE: K3 Main/Sub audio routing

Without the second rcvr, is there a way to get a different level of audio on two channels?

With the second rcvr, can do, I think.

I have, LIKE SO MANY OTHERS MY AGE, a hearing loss in one ear and need a "balance"

control on the K3 to compensate (or find a nice headphone with vol. controls on each ear).

Re: K3 Main/Sub audio routing

Charles
In a mono audio situation, you could connect a 100 ohm pot
as a balance control fairly easily. Connect the hot leads to each
ear piece to the ends of the pot, and connect the hot lead coming
from the radio to the pot's wiper. Now as you vary the pot, more
audio will appear in one earpiece or the other. If you have a lot
of audio power, you might want to use a pot good for a watt or more,
just to keep it from being heated by excess audio power. For
headphone
use, I wouldn't think this too likely though.
Good luck and 73
