[Elecraft] K3 SUB AF - NOR or BALANCE?

Barry,

The problem for me was having the balance control on the outer concentric 
ring of the knob set.  I modified my K3 so that the top knob set is 
configured for MAIN AF/RF Gain, with MAIN RF Gain on the outer knob, and 
MAIN AF Gain on the inner knob.  The SUB AF/RF function is now located on 
the bottom, with the SUB RF Gain on the lower outer knob, and SUB AF 
Gain/BALANCE on the lower inner knob.  The ergonomic difference is like 
night and day.

When I activate split, I can manipulate the lower inner knob between the DX 
station and the called station.  I really detest having to manipulate the 
outer ring to balance between stations.  The propensity for disrupting the 
alternate knobs is much greater.  Further, at the suggestion from someone 
else on the list, I replaced both knob sets with Alcoswitch black anodized 
types through Mouser.  The inner knob extends just slightly more, making the 
DX split experience even more enjoyable.

The mod is easily reversible and requires swapping pot leads on the Main DSP 
board.  An even better solution could come from Elecraft through firmware. 
Since the pots are all of the same resistance value, a firmware command 
could be used to swap these functions.
