[Elecraft] Multiple radios with KAT500/KPA combo

[Richard Lawn]

I have a setup with 4 different radios on the bench and I'd like to use
them all with my KAT500 and KPA500. One of the radios is a K3. The others
of course all have PTT outputs. I suppose there is no way to do this short
of making a switch box with all PTT lines from the 4 radios and a single
output to the PTT in on the KPA500. If I'm missing a possibility please let
me know.
