I do this with my Alpha 9500. But differently than K9YC. I use the two antenna ports on the K3 and an Alpha Delta 2 position switch. Antenna one on the K3 goes to the KPA500 input. Antenna 2 on the K3 goes to the 9500 input. The output of the KPA500 goes to position one on the Alpha Delta switch. The output of the 9500 goes to position two of the Alpha Delta switch. The common of the Alpha Delta switch goes to the antenna switch. When I want the KPA500 the K3 is on ANT1 and the Alpha Delta switch is on position one. When I want the 9500 the K3 is on ANT2 and the Alpha Delta switch is on position two. Since the K3 remembers power by band and antenna, when I'm on the KPA500 regardless of band it has the correct power setting to give me 500 Watts or 200 Watts on 30 meters. When I'm on the 9500 the K3 has the correct drive power for the 9500 for that band. That is how I do it and it works for me.

I'm considering adding a bigger amp to the shack. I'd like to continue to use the KPA/KAT combo for quick hits and the bigger amp if/when needed. So I'd like to make it convenient to switch between them. The people I've talked to so far actually move coax to make the switch. I'd like to avoid that. I'd need to switch the K3s output from the KPA to the AL1500 and obviously switch the outputs as well. Obviously I'd also need to set the non-KPA power out of the K3 to the per band power needed by the AL1500. I seldom run 100w so that wouldn't be a big deal. I'd love to hear from anyone who has done this without screwing/unscrewing UHF connectors. Extra credit for idiot proofing. ;-) 73 jim ab3cv ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to markmus...@sbcglobal.net ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
