P3 SVGA

[k9mx]

The SVGA adapter for the P3 is a lot more sluggish than the P3 display
itself.  Whenever I move the tuning knob, the display flattens out at the
bottom of the screen and then recovers.  A few days ago I managed somehow to
freeze the P3 display.  When I did, the SVGA display suddenly started
working beautifully, maintaining nice displays even when I tuned and with a
lot more resolution than the P3 (which is what you want).  Unfortunately, I
managed to "fix" the frozen P3 display so now I'm back to the SVGA display
as it was before.  That suggests to me that the processor can't manage both
displays at the same time.  But whatever the cause, is there a function I
didn't realize that allows me to freeze the P3 display to improve the SVGA
display?  If so, I'd sure like to know what it is.

Hi David,

What are the versions of firmware in your P3 and SVGA boards? (you can find this out by connecting the P3 utility to the P3.)

It sure sounds like you have some early firmware, the flattening out of the spectral trace when moving the VFO knob was fixed some time ago.   BTW the SVGA is going to be slightly slower refreshing as compared to the P3 since it is performing twice the FFT points and is displaying up to 4 times the display pixels.  If you need help, please email me directly.  My email is pauls at elecraft .
