Just for testing, did you try putting each channel in its own favorite and scan them?
How about trying the IFX?
I think I did. I will try it again tonight. As for IFX, I saw that lastnight but I am not sure what it is/does. It looked like some kind of interference thing and I really don't think this issue is interference because the scanner receives the transmissions with no issues. In Quick Search the transmissions come through clear with no issues at all. It's only scanning Favorite List that it won't work at all anymore.
