Thanks all for the replies!
I have a basic understanding of the ADS-B system and I did return the Sagetech unit which was a dual band receiver. This could be my issues with not seeing any commercial traffic, although I think I remember seeing some with the iLevil SW... Oh well chaulk it up to old age!
Thanks Walter, I left shortly after I called to repair an item at my business so the phone went to fax (home office line).
I think this answers what I had questions on.
Cheers everyone!
Paul
