I have all 8-pole filters in my K3. I've always noticed a slight audio response difference between LSB and USB positions. Read some list history on the topic. I do have a wideband noise generator and spectral analysis software, but have been too lazy to get everything set up. So I did a quick and dirty, just equalizing the receive response aurally on all of the installed filters.
Ended up with -0.12 on the 2.8, +0.06 on the 1.8 and -0.05 on the 400. I'm curious wether the experts around here think that's close enough for government work, or if it's really worth going the spectrum analyzer route. Could these results just be due to unequal skirts, and maybe I should just "don't worry, be happy" and leave the 8-pole offsets set to zero? Thanks ...
