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.
Thanks,
Dan
