My issue was similar, but with the 50 watt calibration. A recent firmware upgrade required a 5W and 50W re-calibration. I hadn't done a calibration since the early days of the radio back in 2008. The radio has worked fine all this time. It is on almost every day.
With the tuner in bypass, I failed the 50 watt calibration on 52 MHz with an SWR >2 to 1. I finally got the calibration to pass by connecting the dummy load directly to the K3 antenna connector, without the cable. The SWR was still not 1 to 1 on 6 meters, but it was low enough to pass the calibration. I chalked it up to a tuner-bypass issue on that band. But I never went back to take a closer look. I seem to have a lot of RF in the shack on 6 meters now with my center-fed zepp. Perhaps better station grounding would help in that area. 73, John W2XS -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ 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]
