[Skimmertalk] Skimmer Frequency Calibration

[Ed G]

Hi Folks,
     Could someone summarize the recommendations made related to Skimmer
frequency calibration?  When using Skimmer to link to N1MM (using Skimmer as
my telnet source) the Skimmer frequencies are about 800 Hz off, so
point-and-click doesn't work very well.  The "calibrate" option in Skimmer
is grayed out.  I'm using a K3 as the main rig, with SDR/IF also running.
Thanks for info...
