KAT500 leaves unselected antenna ports open circuit and defaults to port 1 when power is removed. The relays are not latching.
I don't have details for the KPA1500 but the ATU board photos available here - https://fccid.io/UTR-KPA1500 - have high enough resolution to trace the output signal paths. I have been told these photos are of a prototype and may not represent the production configuration. 73, Andy, k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
