I recently acquired a used PX3 and am quite pleased with it. I am, however, having a difficult time with the carrier null procedure. If memory serves, I had a problem trying to do the carrier null on an SDR I built five or six years ago too.
I never could quite get the signal generator in the PX3 to get to -40. It stayed around -45. I did write everything down and did try to adjust the nulls but I’ve either got too much noise in the shack or I just don’t know what in the world I’m doing. Right now, I’m listening on 75 m and I can see the center carrier plus mirror images of each side of the carrier. The span is set to 50 kHz. Any certain way I’m supposed to “hold my mouth” or “stick out my tongue” while I do this? :) I’ll bring home a service monitor from work tomorrow and hope it tunes down as low as I need it to go. 73, Joel - W4JBB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
