Your amplifier should be close enough to a 50 ohm drive impedance that the bypass mode in the K3 is easily usable when driving the amp. If you need an ATU to drive the amp, it is a problem of some sort with the amp tube, its input circuitry or connecting circuitry. I have seen a bad 3 foot piece of coax between a transceiver and amp make the amp appear undrivable.
What is the indicated SWR on the K3 display when driving the amp? If it's not 1.5 or less, got work to do on the amp. 73, Guy. ______________________________________________________________ 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
