I once had this problem too. I traced the problem to the routing of the ribbon cable from the K2 to the KPA100.

I've just completed the initial testing and alignment on the KPA100. Everything checks out fine. All resistance and voltage measurements are within spec and I'm getting 100+ watts out on all bands. However I'm getting some annoying noise from the RS-232. My software polls the K2 every 250ms (4 times per second) and it generates noise on all bands every time it's polled. It's coming through load and clear. It wasn't there with the KIO2, so I suspect I may have a problem somewhere in the KPA100 RS-232 circuitry. Is this a known problem, or do I have something wrong? I can't find anything searching the archives. Thanks.. -David W4SMT _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
