[Elecraft] Adding PTT Out Switching to a K3

[N4ZR]

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?
