I saw alot of these stations back in the early 90's...I'm vearing off topic here....
The sheriff's department where I live had a Motorola Micor station that was their 39.58 receiver (and backup TX), but it was dual receive for 39.78 (and back up 39.72 TX), which was their 1/2 duplex car tx frequency, and then they had a MASTR II station which was the 39.72 TX to the cars, and 39.58 tx too. Reason - full duplex on the car to base / base to car..they could hear one car while talking to another (on separate stations), redundant 39.58 (statewide in those days), and mostly because the Motorola received better, and the GE had better TX audio. I think the Moto was 100 watts and the GE was 250 running about 175. They were on the same building, both on DB201 antennae and at different heights and sides of a water tower.
The cars had Micor mobiles and could TX on 39.78 to talk to the base, 39.58, and 39.72...because they also scanned 39.78, along with 39.58, and 39,72 (priority). Interesting setup.
Oddest station I ever saw was a UHF MSF that was a T4 4R configuration, and was a 12 watt station. It was used for a control base, 4 different repeaters, could TX to them one at a time, but hear all 4 anytime. It had preselectors, and a duplexor like a repeater. The rx audio from the repeater you were txing to was simply muted at the console, and the position you were using, to prevent feedback. It was for a fire dispatch.
And lastly i knew of a VHF IMTS that ran 330 watts, had a receive antenna at 180 feet on a 1800ft hill, and the tx was at 100 feet on that tower....that thing would talk. Once it was down to about 80 watts and no one noticed, but at that point only 1 Moto service guy in our shop still had a mobile and the company it belonged to had 5 or 6 and didnt use it much.
