I have 240VAC in the shack to run my legal limit Ten Tec amps, but I've never taken the trouble to add another outlet so I could use it for my KPA500. I'm running on a 120V/20A circuit that' probably about 50 ft of wire from the panel. I get 550W out on 6M and 675W on the HF bands. If the match were better on 6M I might get a bit more. If you already have 240V in the shack, all it takes to try it is to buy a new standard IEC line cord (but buy a #14 -- most standard IEC cords are #18) and stick a male plug on it that matches your 240V outlet. If you don't have 240V in the shack, I wouldn't worry about it. And there are instructions in the manual about how to change transformer taps if you need to for full power. FWIW, I don't think Ron's 60 ft of #14 is anywhere near worst case. In many houses you can have 100-200 ft between the panel and an outlet, often with multiple outlets daisy-chained, and with shared neutrals. 73, Jim K9YC ______________________________________________________________ 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
