Sitting in the parking lot at the airport in Milwaukee, WI, earlier this week I heard what I believe to have been the TSA on 172.1500 NAC 2 in the clear. The content of the traffic was consistent with it being TSA, e.g., "Red sweater, center lane".
I also heard what I believe to have been encrypted TSA on 169.300 NAC 9 from the same location. Sounded like someone with a mouthful of marbles.
From that same location I heard an analog transmission on 406.5375 in the clear which I believe to be the USPS. There is a major USPS facility near the airport.
From a different location I heard a 2:00 p.m. net rollcall on 406.200 NAC 201 which I believe to be the Federal Protective Service. Also on 409.9375 NAC 482 I heard what I believe to have been an encrypted USPS transmission. Also 167.2250 PL 162.2 in the clear -- DHS?
