[MRCA] AN/TRC-1

[Ray Fantini]

All of this talk about frequencies and licenses makes me want to rant about one of the stranger projects that I want to do. For no particular good reason I want to build up a AN/TRC -3 four channel carrier phone system for use somewhere, maybe at Gilbert or wherever. For those of you uninitiated the TRC-3 is a pair of TRC-1 receivers and transmitters along with a CF-1 Carrier telephone terminal. Have seen lots of TRC-1 radios around for sale and no one ever appears to buy them considering that they are wide band audio and operate by crystal control in the 70 to 100 MHz range.
For years now I have wanted to attempt the challenges of locating all the parts like the telephone multiplexer, spiral four cable and the very mysterious TRC-1 antenna kit that I have never seen yet alone saw one for sale. But the biggest issue is the operational range being above six and below two meters. Think there may be some sort of pager operations or something like that in the 70 MHz band but not certain.
Also would be interested because this will be one of the rear occasions where I admit I don't know it all but was there multiplex carrier equipment for use with the VRC-12? I have a log periodic kit that its label implies that it's for a multiplex system in the 30 to 80 MHz band and maybe a Vietnam era system would be more appropriate to what I want to do.
At Fort Miles when I do things there they have a couple people that are into the wire line communications way of life and thought this would be a great opportunity to integrate wire line with radio beyond just doing a simple signal pair remote control. And there does appear to be a lot of that TRC-1 stuff around. Was any of it ever modified for two meters? I have no issues running wide band FM across someone's repeater input.
