P3SVGA Display Pan Level Change When Turning VFO A or B

[W6NEK]

Hello fellow owners of the P3SVGA Display Board,
I must be missing a menu setting.  Whenever I tune either the main or sub VFO the external VGA average pan display trace drops from -120 dbm to -135 dbm all the while the VFO is changing frequency.  This makes it all but impossible to visually tune to a weak CW signal by just watching the VGA pan display as you tune the VFO.  Each time I stop tuning the pan display jumps back up to the -120 dbm reference line and all the weak signals once again appear in the pan display.  This does not happen on the small screen pan display.  Is there a separate menu adjustment that prevents the VGA pan display level from dropping -15 dbm when the either receive VFO is tuned?  I just know I have something set up wrong in the menu system.

Any input welcome,
Frank - W6NEK

I've noticed the same thing -- in tracking mode, but not fixed mode. I don't know the
reason for it and I'm pretty sure that there's nothing you can do about it. You might see
if you like fixed mode, which I greatly prefer.

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

Do you have the P3 in Tracking or Fixed mode?
