[Elecraft] KRC2 + K2 + XV + PC = cabling confusion

[John D'Ausilio]

Heya Jack ..I took the "easiest" path and just connected on the PC
side of the KRC2 .. 2,3,5 to the PC, 6,8,9 to the XV and added
necessary jumpers (all but ALC). Only thing I'm worried about is the
total cable length on AUXBUS, from K2->KRC2->XV is about 4 feet ...

I'll know later today when it moves off the bench and into the jitney :)

thanks
jd
