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).

When operating non-split you would hear the sidetone in both ears. When
in
split mode the sidetone would appear to come from either the left or the
right headphone to audibly remind you that you are in split.
If you are working a DX pileup split and you hear your sidetone in both
headphones....yell to yourself "UP! UP! UP!".
Any opinions / dangers / drawbacks to this approach?
