39.620 and 37.900
Are there still antennas on the vehicles for these bands?
Or do you think these are handhelds being used inside vehicles?
Although many of the cities and townships just go ahead and renew the licenses when they come up, I didn't think ANY police or fire was still actually using freqs that low anywhere in Metro Detroit.
This MAY be strickly communications at one location, like a DPW yard or a city hall. Curious if you only hear it during normal working hours. One city downriver did that for a while, used old lowband (I can't even remember what the freq was, somewhere in the 42-46 mhz range) mhz handie talkies to keep track of each other inside the buildings, after the parks and recreation went to 423 mhz.
Could also be communications at a parade or a high school football game. Old radios don't always get tossed, they just get handed down.
