[Elecraft] K3 Beta firmware rev. 2.67: Main/Sub AF balancecontrol; AGC-off AF limiter

This is an excellent feature improvement.

Assuming its possible in the hardware, I still like the concept of dual L/R 
audio for VFO A and injecting Sub Rx from VFO B to the R channel (e.g., DX 
in both ears, calling stations in right ear only), provided that the 
addition of such a feature does not otherwise compromise Rx performance; a 
concern rightfully voiced by W4TV.  However, since these mix/balance 
functions are occurring at the AF level, I suspect that degradation risk to 
Rx-to-Rx isolation is low.
