I found the issue with my 10b sideband suppression. I needed to re-align L2
again. Before re-aligning it when I switch back and forth between sideband 1 & 2 positions and listening to say only LSB on my 75S3 with a 1200 hz tone fed into the transmit audio input I would see the same signal level on the receiver s meter. There is a definite null when aligning L2 that I missed. Now when I switch back and forth between the sideband positions I see a 3 to 4 s unit drop on the receiver. If I switch the receiver to USB I see the same drop when I switch from sideband 2 to 1 position. I have to say the audio does sound pretty good coming out of this little rig.
Thanks
