Hi David & Group, I did find the spec for the input SWR in the manual - it's listed as < 1.5:1, so my amp is well within spec. I'm going to forget about it. I guess I'm used to old tube amps with tuned inputs you could adjust on a per band basis. This is my first SS amp, so I'm learning.
Sorry to hear about your troubles and I'm sure they'll soon be fixed. Fortunately, my amp functions just fine and my SWR observations are symptomatic of nothing other than my own obsessional nature. Does anyone know the design reasoning behind using the twisted wire pair, rather than coax, for the RF output connector on the KPA500? There must be one, but I wondered what effect that would have, if any, on the impedance of the RF path through the amp. The RF input connector is coax. 73, John VK7JB ______________________________________________________________ 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
