[Elecraft] P3SVGA Display Pan Level Change When Turning VFO A or B

[W6NEK]

Hi Vic,
Many thanks for the feedback.  Yes, Fixed Mode works FB.  Guess I'll just 
have to get used to using this mode when the VGA display is enabled.  Must 
have something to do with the processing power available to redraw the 
entire spectrum compensating for continuous frequency updates in Tracking 
Mode.  LP-PAN/NaP3 displays properly in tracking mode but then again I have 
a Intel I7 powered PC doing the heavy lifting ;-)

Thanks again for the info,
Frank - W6NEK
