[Elecraft] Audio mod for split operation

[W3FPR - Don Wilhelm]

Tom,

Audible indication of split is certainly attractive, but bear in mind that 
the audio is mono in the K2 and the sidetone is injected in the LM380 - 
output is a mono combination of audio and sidetone. Two resistors feed the 
headphones primarily so that mono headphones will not short out the audio.

Reducing the sidetone in one ear while retaining full receiver audio would 
require a complete redesign of the audio section - do-able, but it would 
take some design effort and space to install it.  At the present time, space 
is at a premium for the K2/100.

As an alternative, it should be easier to reduce both the receive audio and 
sidetone when split is active (break the signal to one channel of the 
headphone output).

73,
Don W3FPR
