[Elecraft] firmware suggestion for k3

[Gary Lee]

I would like some sort of audible indication that a reasonable match has 
been obtained with the autotuner.
I sugggest "k" for a match, and "s" for swr alert.

Failing that, and maybe easier since you have the switch tones in place, a 
high pitched beep for good match and low for no good.

Being totally blind, this would sure increase my confidence operating the 
k3.

What you all think?
