My KPA500 puts out 600W - 675W (I've seen occasional peaks of 700W without faulting) into a reasonably matched load on the HF bands (1.5:1 or better), and 560W on 6M into a load of about 1.4:1. If the match gets to about 2:1 on the HF bands, it might fall back to 500-550w. No issues with nuisance faulting. 73, Jim K9YC ______________________________________________________________ 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
