I personally don't think the K3 balance is that useful for contesting 
because the knobs are too small, concentric, and in a cluster. I strongly 
prefer switching on an external panel. The boxes on either side of the K3 
select audio lines and the particular antennas, the rotary circle on the 
sloped box to the left between the K3 and Yaesu controls directions.

The only time anyone needs diversity mode is when receiving weak signals all 
from the same direction, or perhaps on SSB/RTTY so receivers are always 
locked. The K3 already does everything we use in contests! Sometimes it just 
takes an extra external switch or two to do things right, fast, painless, 
and easy.
