If I go into service types on my scanner and shut off law tac and interop then the "departments" titles "statewide interoperability" which is a Interop and "Zone 1 Interoperability Metro" which is a Law Tac disappear. However, there are TG's such as PS COMM (4920) TG that Scott County has that is listed as "Interop" still remains even though I have Interop shut off. Same for Law Tac, any of these C2C Tg's or tac TG's (which are all under Law Tac) will still show up in the scanner even though I have Law Tac shut off but the Zone 1 Interop Department heading will not show up at all, probably because the entire group is a Law Tac. That is what I was saying when I said the TG's that are interop or law tac service types that are mixed in with other service types within a department will still show in the scanner even though I have those service types shut off but if a entire "department" is of the disabled service type then you wont see it in the scanner.
L Tac is definitely interesting at times and you can get things from all over the state. I am by Shakopee and a week or two ago I got a pursuit on L Tac 1 that was in Becker County, it went on for awhile and finally ended in Detroit Lakes. S Tac is another good one, they seem to use that for ground units to communicate with medical helicopters. Metcom is kind of quiet, once in awhile I'll hear something on there but maybe I am too far from the cities to hear everything on there
