I would like to come back to this topic with an update after still experiencing the same issue.
I now use my ZS6BKW with a 1:1 current balun between the twin line and the coax. I have tried a 70' and a 30' length of coax to the rig. If you think it will solve the problem, I might even try a 5' length and smolder in the sun! My battery shows 11.4 V during transmit on the KX3's PS meter. SWRs are never higher than 1.3:1 after tuning. PA temperatures are never very high (sitting in the shade). I have tried lower W settings, like 8W, which, on some bands, hold for a while. On other bands, they too revert back to 5W. So, if this is all normal, I don't understand why the KX3 is rated at 10W. Or asking in a different way: what needs to be present to keep the transmitter from reverting down from 10W, and how can I achieve that state with my setup? Please keep in mind that I don't have any antenna analyzing instruments other than what the KX3 provides. Thank you and 73, Arno K7RNO ______________________________________________________________ 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
