So what I'm getting out of all this is that's best to program as many MIl-Air frequencies as possible, not just the ones that RR's database shows in use for a particular area? That being said if you simply use the airband search on say a Uniden BCD996P2, will you search all of them and negate the need to actually program them all?
Breaking things into scan lists could help. List by state, distress, and nationwide, as an example.
Since you are a fellow Troll, don't forget the MOA over Lake Huron, and Camp Grayling range, that are often used in conjunction with Alpena CRTC. Plus anything over Ontario, as the Canucks do stuff all the time, too. (For any non-Michiganders: Troll means that we live below the bridge.)
