While getting ready for the Elecraft net today my KPA500 would not transmit. In bypass mode swr is 1:1. When placing in operate mode I get no output with my K3 showing high swr. Tried my loop, vertical, and Hex beam. All show low swr on the K3, KAT500 and the KPA500 in bypass. I took the KAT out of circuit and no change. Unhooked all antennas and then reattached one at a time, no joy. Ran a new coax between K3, KPA500, and then just between the K3 and KPA500 and got the same thing. Can run 100 watts out with K3 with low swr on all my hf antennas as long as KPA500 is bypassed. When I put it in operate I get no output and K3 shows high swr. It has been working flawless on all bands and modes. Usually run 28 to 32 watts input for around 500 out. Anyone have any ideas on what might have happened. Thanks for any thoughts.. 73, Don, W4CBS Sent from Yahoo Mail on Android ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net
