Mike,
I don't think I have seen this as a suggestion so far in the thread.
It is important that you dress the cables for the SVGA option exactly as
shown in the installation manual.
If they do not want to stay in place, use a ty-wrap around the cables.

Somehow I managed to lose my last post describing the attached photo.
suffice to say my Span is set for 14.000-14.104MHZ and my cursor is tuned to
14.029, but notice that the baseline noise level while near S-2 across most
of the band, shows a hump back at the center of the screen and the
I am almost overwhelmed by all the very thoughtful suggestions. Here's what
I know so far.
I had previously performed the idea of turning off all items in the room
except for the radio and P3, but the reported symptom remains. I then
switched my antenna switch to the grounded position, and the

Have you tried turning your monitor off? I've never had the issue

Mike,
You didn't mention if you had a large monitor connected but
consider that the noise you "see" may come from it or a TV

Do you see the pattern on the P3 also?
Watch the P3 screen and turn the large monitor off and see if
the signal disappears. Many of them do make a
I wonder if this discussion and suggested ribbon clips address my issue. I
acquired my K3 this past summer and then a P3 off of eBay shortly
thereafter. I installed the SVGA adapter a couple months ago and I have a
problem which sounds similar to what is described in this thread. For lack
of a
I've found some adhesive clips that will allow the ribbon cable to be dressed
along the left inside panel. They should be available by the end of this
week, by request, no charge (EPN: E980228). All future P3 kits and factory
assembled units will be getting them as well.
Thanks for all your
tie.

Hi Bob,

I just got a message from yet another P3 user who by moving the ribbon cable
away from the internal IF coax removed the extraneous phantom signal. He
did NOT have the SVGA.
Elecraft - I suggest providing a shorter ribbon cable or a means to dress
the cable in a straight line from front PCB to
Hi Bob,
We're taking a look at it now. A shorter ribbon cable is a possibility, but
maybe there is a simple way to dress the existing cable by folding it and
holding it with some sort of clip. Just thinking out loud.

I can agree with you regarding the IF oscillator oscillating since when I
approach the coax it changes the conditions stopping the oscillatoin. BUT -
if it was the P3's IF amplifier going into oscillation I would expect the
display to freeze as no IF signal would be able to pass. That does not

inside the P3. We both noted it started after installing the SVGA.

Is it possible the ribbon cable is as long as it is because it will need to
eventually be routed around something else to be added later?

There is (was) a known problem with the MMIC amplifier (comprising the IF amp
into the P3) oscillating.this instability could certainly manifest itself in
what you are seeing.
