Hi Lyn, Thanks for your report. Your KAT500 is a later serial than mine so I doubt R7 is fitted. (Mine was a kit build and I don't know if factory units are in the same serial number series)
I don't know the source of my Rev C schematics. I received some of my KAT500/KPA500 from Elecraft support and some by an internet search. I assume there must be a later version that documents the elimination of R7. 73, Andy, k3wyc ______________________________________________________________ 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]
