That was with no RF out it bumps up to about -80 on the display with 17 watts out displayed under fldigi. DM780 has a spurs too. -100 on the display with 26 watts out on the display at 14.070. -80 on 7.035 with 21 watts actually on the air. I guess I am just overly concerned with what I can see.
I don't see a filter as a solution as it defeats the purpose of how PSK31 software works. You could be constantly modifying your filter where you should just be selecting a frequency with your mouse. Since radio is better the software needs to be better too.
