Wayne, Thanks for the response. I waited to respond until the KPA1500 manual was published to see if there were any PF1/PF2 functions out of the box. What I'd like to see first is much less fancy than interacting with external relay-based antenna switching like you mentioned. How about initially providing a second set of ATU segment memories to allow a /manual/ external switch? The amp can't know or control which antenna is selected but it would be very handy to have a PF function key the operator could use to toggle between ATU segment set one and two, for example, when the manual antenna switch position is changed.
I envision it like this: ANT1 \ Manual Switch \--: Antenna 1 (Manually select ATU logical segment set 1 with PF1 tap) \--: Antenna 2 (Manually select ATU logical segment set 2 with PF1 hold) ANT2 \ Manual Switch \--: Antenna 3 (Manually select ATU logical segment set 1 with PF1 tap) \--: Antenna 4 (Manually select ATU logical segment set 2 with PF1 hold) Just a manual logical segment set change in support of manual external antenna switching. Is that do-able? I imagine I'm not alone in the use of manual antenna switches and needing to accommodate more than two antennas without the ATU experiencing a high-SWR-triggered re-tune hunt each time an external switch selects a different antenna.
