[Elecraft] Multiple radios with KAT500/KPA combo

[Dick Dievendorff]

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.
