I'm pretty sure we're talking about two different things.  The sort of 
broadband "hump" [maybe 6-10 KHz wide] I see moves all by itself, 
usually from high to low frequency, and at a very stable, constant rate. 
  It just makes a pass through the screen, and I've never seen it with 
no antenna.  If I'm in a contest and thus on the air fairly steadily, I 
might see it about once every 90 minutes on average.

The PP at Beale AFB is a phased-array radar and looks all over the place 
in milliseconds.  It's not far above sea level, we're at 1,800 feet, and 
I hear it on 70 cm every now and then.  I don't think that's the source 
of the above, however.

As I mentioned, my P3 is somewhat "case-sensitive."  Getting good 
contact at all the screws, and tight screws, seems to be important.  The 
paint masking on mine looked really good, so I skipped the "sand off the 
paint mask points" instruction.  In my defense, it seemed like a good 
idea at the time.  I do wish there was a grounding screw on the back of 
the P3 that I could bond to my single-point safety ground.  Other than 
that, it is working super and has added several new ones to my DXCC total.
