Jerry,
I also would encourage you to look at the KRC2 for your solution. It
will provide BCD band output as well as individual outputs for each
band. Use whatever is compatible with you amp.
The K2 on its own does not provide external band data except by decoding
the propriety AUXBUS data. The KRC2 does that for you.
Your solution may depend on your programming skills and the amount of
time you wish to dedicate to the task. The KRC2 already has the decodes
and yes, it does cost $$$, but you have to decide how much your time and
effort is worth compared with the KRC2 cost.

Hi Jerry,
There is no simple access to band data in
the K2 unless you want to reverse engineer
the AUXBUS protocol.

async protocol, that might not be that hard.
Depending on how
your homebrew amp selects its lowpass
filter options, you may be able to pick up
the relay control signals for the K2's bandpass
and lowpass filter banks and use those
to encode a band data word in the format
used by Yaesu.
