Hi Group,
?
I took the plunge today and installed the second SSB beta FW on my 80-20m QMX.? Did the calibration and tried it out.? While I do hear myself well on my nearby Flex 6400M with no antenna, I also hear a fairly high pitched tone and the spectrum (outside of the TX voice passband) looks like "long, slow downhill slopes" if you will.? See picture below of 6400M spectrum/waterfall.? At first I thought it was the mic(s) I was trying, but then thought to try my Behringer XM8500 with the proper wiring to the QMX Paddle input.? Seeing the same thing on all mic's.
?
Is anyone else finding strange sounding audio (audio with high pitched tone) and/or very wideband noise outside of the voice passband?? Maybe I am doing something wrong in my setup or testing thus far given the positive reports I read here?? Thanks for any advice, I'd love to be way wrong in what I am seeing!
