Oh dear lord.  Please tell me more about this, or point me in the right 
direction.  We've got a KPC3 on the mountain someone gave us to use.  How can 
you possible f-up KISS mode?

I think the AT328 modem from here:
http://sites.google.com/site/ki4mcw/Home/arduino-tnc has great potential.  I 
can see doing this as a kit at a club meeting.
A TNC shouldn't cost more than $30.  All it does is convert sound to serial 
and back again.
