I discovered a problem this afternoon where the KPA500 is faulting on 20, 17 and 12 meters. Set up here is the K-line, K3/KAT500/KPA500. Everything had been working fine until this point. I get a hard fault (error code 9) on the three bands which means excessive SWR even though it has tuned fine before switching from standby. Antennas: 6BTV vertical and Inverted Vs for 17 and 12. The Vs are fed from a common point. The KPA500 works fine on 80 thru 10 on the 6BTV except 20 of course. I tried turning down the power when on 20 (via the K3 drive) but the SWR runs up and faults.
I checked the Elecraft website but no schematics for the KPA500. My guess is the LPF units for the bands in question have gone TU. 73 de Ed ______________________________________________________________ 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]
