I believe PSDR reads the offsets for each different filter and automatically
corrects, although I have not used PSDR in nearly 3 years so I could be
wrong. Skimmer only uses a single offset entered in the Setting Menu. The
information about different filter offsets is available in the K3's output
but Alex does not use it. I also wish he would lift the 24 kHz limitation
for the Software on IF mode used with the K3 but so far he hasn't.
I use Skimmer directly with the K3/LP-PAN (no PSDR) since I much prefer its
waterfall. PSDR is nice but overly complex for what I need.
