In a follow-up to my original comment Bob answered off list and I suggested a ground problem. He replied:
"Ron, you hit the nail on the head. Problem turned out to be old ground connections at the towers and the ground rod outside the shack.

What does seem strange is that the K3 was unaffected, but the KPA500 running only 50 watts would fault (high swr) and shut down. 73, Bob" It does underscore just how rig-specific and installation-specific such problems can be. Also, "Connections that look good might not be" Hi! 73, Ron AC7AC ______________________________________________________________ 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
