I think I found the culprit thanks to the mention of "no key cable connected when using the KPA-K3 AUX cable." (I already checked the TX:INH" item and it was OFF)
I had my key cable connected to both the K3 and KPA despite also having the AUX cable between the two. I had left it connected ever since I was initially having trouble with the amp right after I built it---that trouble was due to one of the ribbon connectors only being connected to one row of pins which I soon fixed. Thereafter, I forgot about having the key cable still in play. This morning I unplugged the key cable and turned on the KPA, hit the mic button and voila! The amp powers up 1st time on every band as it should! Aha! Hope this helps others who might be experiencing the same problem---it's not sticky relays in the amp it's sticky relays in my noggin! 73, Jeff, NH7RO -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA-500-no-RF-until-power-cycle-tp7017734p7032171.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
