Thanks.  Deoxit on both connectors seems to have "fixed" it.  I really 
wish my P3 had a ground screw, just on general principles if for no 
other reason.  I think I'll make up a piece of RG-58 with a BNC on one 
end, and the braid pigtailed on the other and connected to my single 
point ground.  I can then plug it into the IF OUT jack on the P3 for 
grounding.

I'm fairly certain whatever is causing the problem is at the "far 
display end" of the P3 receiver chain, the entire "receiver" part seems 
to be unaffected, it's just the baseline.  Noise and signals go up the 
little "baseline hill" just as they do when it's horizontal.  If you see 
this, lay your hand on the top of the P3.  For me, that returned a 
normal baseline.
