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.

I would run the single PTT to the ATU rather than the amp, and a single PTT line to the amp from the ATU.  The KAT500 needs to be able to break the PA key line to tune (switch small relays) at less than the full output of the PA.
