Well I'll be darned. I just pulled that cable out of the K3 and it is
indeed redundant. I must have missed that in the manual. Thanks, Bob.
While I'm on the subject, I wish that Elecraft would clean up their
terminology - their use of "Key" to denote PTT is confusing. See the
back panel of the K3, for example, which has PTT IN and KEY OUT jacks in
the same row. I believe this usage originated with CB.

Connect the KPA-1500 via the ACC cable and thus free up the PTT
output. The system is very smart and works exceptionally well. I use
this method with my KPA500 and KAT500.
The PTT Out is connected to the VHF transverter.

I need to be able to disconnect the antenna to my SDRs when
transmitting. This used to be easy but now my PTT Out jack is
committed to the KPA-1500. I'm looking for suggestions of how best
to accomplish this - I don't believe sequencing is required, just a
second PTT output.
Ideas?

….thanks to comments and suggestions from K9ZTV and W2CS.
My K3 has the Sub Receiver installed, and I have been playing around
with
diversity reception, using a random wire connected to the sub-receiver
antenna input BNC connector. Apparently the carrier operated relay
that
protects the receiver from overload is being triggered by lots of RF
coming
into that random wire. When I disconnect the receive antenna, no more
clicking. Now that I know what it is, I'll just ignore it. Or maybe
someday
I'll rig a manual T-R switch arrangement to disconnect the sub receiver
antenna except when actually using it.
Thanks, gents!
