The other morning I powered up the station to have a listen but left the KPA500 off. The rear panel power switch was left on and I had powered the amp off the night before by the front panel switch.
There was no signal getting from the antenna to the K3, evidenced by absence of band noise on 160 m. I turned on the amp with the front panel switch and then it connected the antenna. (Why did I turn the amp on, you ask? I was going to poke a band button and try a different antenna.) Somehow the KPA500 had "powered down" with its T/R switch in the wrong state. I put "powered down" in quotes because it's a software state, not an actual physical disconnection of power. I suspect that if I'd powered down at the rear panel, I would have had an antenna. But I'll never know unless it happens again. 73, Carl WS7L K3 #486 S/W V4.48 KPA500 #750 S/W V1.11 ______________________________________________________________ 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
