The B94MSB-1106A is identified in the Motorola catalog as a 275 watt UHF
Upright Base Station with tone remote control. The word "Motrac" does not
appear in the description. Although it is no longer in print, the manual
that covers this station is 6881011E75.
The C75RCB-6105AT is identified as

In the 1980's I had the following setup:
1978 Camaro with:
100 watt Micor (12 freq) on 10 meter FM
50 watt Motran LLT CHiP radio on 52.525 MHz
Icom 50 watt 2 meter radio
police/fire scanner to keep tabs on local activity
CB radio
All radios individually wired directly to battery
100 amp alternator
Yeah-the SECOND iteration of the Industrial Disaster, er, Dispatcher.
The Ford plants here had a bunch of them on tow motors. ugh.
The FIRST ones were germanium PNP's in the rx, and mostly quick-heat
filament tubes in the tx. For VHF, either .8W or 5W with 2E24 final.

Thanks Mike. I knew that if I was in error, someone would correct me.
Decoding older Motorola stuff is not my "strongest" area. ;-)
But at least I got it right as far as it being a Motran, yes?

I don't remember ever seeing those! I saw lots of U74MST's th

The 43MSN high band mobile was the first all solid
state Motorola mobile transmitter. It was the first
radio labeled Motran and was a direct swapout of the
Motrac - same cable, same head, same everything.

Generally, on Moto model numbers you can go to

If I am decoding the model numbers properly...
The first station is most likely a 250W UHF MOTRAN base station, but has a
tube in the final PA.
The second station is a high-power continuous-duty 800 MHz (or possibly 900
MHz) MICOR. (Check the channel elements for the exact freq.)
