[Milsurplus] Help with identifying an R390-A

[R. Dennis Gibbs]

Michael,

 

This is very interesting.  I looked at all of your pictures.  The only ones I found unusual are the ones of the front panel id plate.  All the other pictures appear to be normal for an early production R-390A.

 

Assuming the id plate is the one that came with this radio (in other words, it wasn’t swapped from another radio), I’d say you have a pre-production R390A on your hands.  I have never seen a label exactly like that before, and I have seen many R390As.

Hi all,

 

I have the Collins R390-A up and running. That burning smell was the variac (first time turning it on). The smell went away the second time I used the variac.

 

The R390-A sounds good and picks up broadcast AM, 40m, 11m with just a 2m/70cm antenna. I haven’t really tried a whole lot more. 

 

However I don’t know who manufactured the radio. There are several Collins components with one or two Motorola components, and there are some stamps/silkscreens that I can’t identify. I think one logo used in a few places might be an old CIA logo. I figured someone here might know. There’s also very little info on the front tag.

 

I don’t think I can attach pictures so I posted them to my personal site. Links are below.

Root directory for all radio images, in case any of you want to check out the rest of the R390-A:

Any assistance is very much appreciated. Thanks!
