I understand exactly what you are talking about -- my case #2, but I 
also realized that what K3TUF and N6XI are talking about was my case 
#1.  Your birdies and noise are from OUTSIDE the radio.  Their's are 
only INSIDE the radio.  I experience both.

Notice that Phil says  "Must be on the IF because it is never heard even 
when it is in the
apparent bandwidth window."

These INTERIOR birdies also get MUCH stronger when you have the SUB RX 
turned on.  During the VHF contest, I split my time between CW and SSB, 
with the SUB RX listening to whichever one I wasn't transmitting on.  
The thing that's a PITA about this is that you think that these are 
signals that you can work, so you switch from SSB to CW to work them, 
but they aren't really there.  There are also some fairly weak 
birdies/noise peaks that look like weak CW signals, but are not.  And I 
worked nearly a dozen weak CW signals that looked like those 
birdies/noise peaks, and as you tune to work them, they also disappear.
