I finally had time to disassemble the circuit board from the heat sink on the KPA100. I haven't yet found anything suspicious on the 10/12/15 LPF, but what I did find was a 'hot trace' on the +12PA line going to the collector of Q4 (provides the bias to the power transistors). I wiped the trace with my finger and it peeled off the board.
I can fix the trace with a white wire, but it makes me wonder if I have more than one problem... 73, AJ4TF -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-100-low-power-15m-only-tp7558733p7559187.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
