[ARC5] GP-x Transmitter, RAX Rcvr? + TU Wanted

[David Stinson]

Is there any documentation- or even a credible story-
of an "official" installation of the 
GP-x series transmitters with the RAX receivers?
I have no doubt that it was done at some time;
the boys used whatever they could get and cobbled-together
all kinds of interesting "sets-" but is there a credible case for this set?
I'm a "completeist" collector: one who seeks to  
find every piece for a particular installation.
After I get my shop built, I'm be forced to make some 
decisions about what sets to build and what to sacrifice to 
space and time considerations.  
I'd like to use the RAXs and the GP-7.  If there's an "honest"
configuration, I could build one set instead of two.
Don't want to duplicate the GP/RU because the RU is already part
of the GF/RU set.  The RAXs are "kosher" with the ART-13,
but I've already got an ATC in my AN/ARC-8.

I'm seeking a "D" range tuning unit for the GP-x transmitters.
I'd even settle for a TDE version for now.

Thanks.
