Heard talk on this TG during the last few months when it was snowing. It sounds like it may be City of Ogden Public Works at the Ogden - Hinckley Airport. Heard snow plows clearing Alfa and Delta, along with a hanger area.
The biggest thing I have heard on It has been the snow plows. I have about 4 UNK Talk Groups in an old PRO-94, that I just let scan to try to pin down who they are and this is one of them. I'm hopeing to get more info on it soon.
