You're certainly not wrong about what you call "grounding" and I call pin 1 problems. :) I do have an HP 3590D spectrum analyzer sitting in the shack, and put a simple loop on it to look at 2nd harmonics from my Ten Tec 425 amp and 160M vertical. It was about -44 dBc when I started, and I got it down to the rated -50 dBc by doing nothing more than changing coax jumpers. Now, I trust your engineering, and your measuring may be better than mine. :) 73, Jim K9YC ______________________________________________________________ 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
