[Elecraft] KPA-1500 antenna selection

[Andy Durbin]

"I'm wondering if it's possible to select the default antenna for when the
power to the KPA is switched off? I'd be fine with "last used", and it
looked like that was available in the KPA Utilities setting, but as soon as
I de-power the KPA, it reverts to ANT-1."

If the KPA1500 uses relays for antenna selection then nothing set in software or firmware can change the state of the relays when there is no power available to energize the relay coils.  With no power to the box all the relays (unless mechanically latched) will have continuity between the normally closed (NC) contact pairs.

What is it about your setup that would prevent you from swapping the connections between ANT-1 and ANT-2 so ANT-1 is used for 6 m and ANT-2 is used for HF?
