Tnx for the comments, Ken.
The IF is well calibrated; in fact I have good sources through 10Gigs so 
that is not the issue.
When you mentioned "adjust the SQUELCH on/off and level slider"  I had 
an 'ah-ha' moment; clicking on the 'SQL: xx' box turns on/off the 
squelch. I had forgotten that was a control, but it does exactly what I 
needed.

Maybe I should just RTFM.
