I have the same problem with mine, too (SN#0250). What I do is switch back and forth between a couple of bands with the band buttons and then it's fine.
I made it into a habit whenever I turn the amp on so I can QRV as soon as I want to and not have to fiddle with it when trying to snag a DX station. I suspect sticky relays; wish there was a good and easy fix for this annoyance! 73, Jeff NH7RO -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA-500-no-RF-until-power-cycle-tp7017734p7029998.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
