Matt, 

Got a note from Art/KA9ZAP and he suggested that I check the NaP3 Config box 
labeled "DC Block". I did, and that resolved this issue.

Thought I replied ALL on my reply to him but I'm not seeing it on the 
reflector, so I might have accidentally clicked on simple reply. Anyway, the 
problem is fixed, at last!!! :-)

73, Jim / W6JHB
