[Elecraft] New K3

[Lyle Johnson]

> Mic gain should NEVER have any influence on Vox gain.

Mic Gain should always be adjusted to provide 4+ bars of "ALC" 
indication on the K3.  This indicates sufficient audio level for proper 
operation of the transmitter, including VOX, CMP, AM modulation and FM 
deviation among other things.

The VOX system gets its audio signal after the Mic amplifier, so this 
setting also normalizes the VOX system.  Thus, one VOX setting is all 
that is required no matter which audio source (FP MIC, RP MIC, LINE IN) 
or microphone you are using.

If VOX Gain was not taken after applying Mic Gain, you'd have to adjust 
Mic Gain *and* VOX gain every time you used a different microphone or 
other transmit audio source.  We have many users who routinely use 
different microphones on their K3s, so normalizing the VOX system gain 
was a deliberate system design decision.
