[Elecraft] KPA500 AUX Cable and KRC2

[n5ge at n5ge.com]

Problem found!

With the help of Paul at Elecraft support we found the problem.

If the PR6 is activating DIGOUT1 Of The K3 KPA500 while when the K3 is in
transmit mode.

This will require (hopefully) a firmware modification to one or both units.

Many thanks to Dale Farmer at Elecraft Support for helping me sort it out via
phone.
