Thank you very much for the good information.  And yes I have things wired 
up correctly and no RFI issues are apparent.  I looked over your tutorial 
briefly and will go back over it again.  I've downloaded HRD as well as the 
DXLab and am currently trying to get them set up correctly to decide which 
works best for me.  I've still got a lot to figure out, but will get there 
eventually.  Another program I have tried is Commcat.  It also seems to work 
well, but not free.  I had it working fine, and then it simply quit reading 
the radio.  Checked for wiring issues, and found none.  I may go back to 
that one and go through the setup again, but it looks like DXLab is 
currently in first place.  I need to settle on one and dig in.
Thanks again,
David Drake
