We seem to have come full circle when it comes to in vehicle and handheld communications devices. In the 70's in Montana we used 100 watt FM radios on 39.82 Mhz in our patrol cars. That's low band not too far from CB radio frequencies.
In the winter when skip was in we couldn't talk to a deputy 20 miles away, but we could hear LAPD put out their stolen car report every morning. In the 80's we changed to VHF radios and the problem went away.
Later cell phones came to law enforcement and officers carried phones. The specialized units started using specialized cell phones with PTT, push-to-talk. These used the cellular network rather than repeaters on mountain tops.
