Don, I tried your experiment but it had no effect. I just grounded point A because it is damn hard to jumper Q7. R28 measures good and is well soldered. It has -0.25V or so on the base side and 5.5V on the other during transmit.
I also tried reducing the drive pot and, while the signal definitely declined in amplitude, the sidebands were still present. Could this just be an artifact of using my K3/P3 to view the waveform? If so, why would the 40m signal be so different? ----- 73, Stan - KR7C -- View this message in context: http://elecraft.365791.n2.nabble.com/New-KX1-low-power-and-20m-oscillation-tp7531133p7541505.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
