Not sure what qualifies for agency. I am a firefighter, but my radios can't do P25 so I don't use them for "work".
I have 2 HTs, and when I first got them I carried them more. They kept falling off my belt, and now they both have rubber bands keeping the batteries on. I got a SignalStick for the UV9P, so it isn't really a "carry" radio anymore.
It is nice to have them in the car to monitor 2m call, local repeater, and sometimes hear fire/EMS page outs for my county. Usually no one on VHF, so no reason to carry on person.
