[Elecraft] Remote control of KPA with the addition of a KAT

[Howard Sherer]

I recently added a KAT 500 to my K3 station. I modified the interface cable
to allow for remote power on off of the KPA via a macro key on the K3. Now
with the cable going from the K3 to the KAT and then to the KPA I have lost
the ability to remote the power on off of the KPA.

How have others retained the ability to remote power control of the KPA
while adding a KAT to their station?
