I knew it was like a simple chat type channel but never actually looked for it. I just picked up a new BC125AT just to keep tabs on Selfridge ANGB and misc. aircraft activity and it became active. I couldn't document what was being discussed as I had my landscaper on the phone at the time.
I get a lot of small aircraft, commercial airlines as well as MilAir over my home near 25 Mile Rd & Romeo Plank Rd in Macomb Twp.
