Motorola used the Mitrek Casting for many other projects
like the mentioned and Loran C receivers. They were quite
up to special projects using a quiver of tried and true
equipment models.
The color of the PC Board (red vs green), the style and
circuit design can tell you a lot about it. Many of the
special projects were made in Texas.
If I saw a picture of it, I could probably tell you more
about it. If it was a special production, the agency
or company for which it was made would now/might be the
only source for the manual, which was supplied as an
"as built" with the equipment.
If you don't know who it was made for... a search of the
frequencies off the channel elements might give you a clue.
