Title: Seeking info on mobile FM set I used in ~1971
Post by: W4EWH on May 12, 2019, 06:06:44 PM
In 1971, I trained at the Army MP school in Fort Gordon, Georgia.

We used a vehicle-mounted FM transceiver which ISTR was called a "VRC76." It had a carbon mike, and used Dynamotor power, and covered (IIRC) ~25 to ~76 MHz. A few of our jeeps had an additional receiver which mounted with the transceiver.

Does anyone have any info on what that set was actually called, where I can get more info on it, etc.?

Thanks in advance.

73,

Bill, W4EWH

 Would think it was a AN/VRC-46 and with companion receiver it was the AN/VRC-47, take a look at:

the field version was the AN/PRC-25 and later PRC-77, that family of radios was one of the longest running line of field radios ever used having been interduced in the mid sixties and was still in use as late as Desert Storm, up until a couple years back a company in Isreal was still manufacturing spare sub assemblies for it.

Thanks for the URL: I spent a couple of hours on the site!

But, I didn't find the radio I used in training.

I'm sure that:

  • It had a dynamotor for power
  • It was FM-only
  • It used a carbon mic

So I guess I'll keep looking. I appreciate your help!

Before the VRC-12 family there was an all vacuum tube family of FM tactical radios like the RT-67, RT-68 and smaller sets like the RT-70 along with their companion receivers like the R-108 If you watch the YouTube movie on the VRC-12 they show that family of radios that were the GRC-3,4 and 5
They were introduced in the fifties and were mostly removed from service buy the late sixties with many surviving in National Guard units until the seventies. Take a look at:

And see if that looks familure. Maybe they kept them around for training that late?

It may be of interest to check out old Fair Radio catalogs......
