[Motorola] Vintage Motorola Trans. / Rec. separate Chassis....30D???

[Jack Antonio]

Can you provide any more clues?

Are there any markings on the chassis, ink stamped, that start
with a TU or TA, or P? This unit is probably too early for
the TRB-xxxx and TTB-xxxx style numbers.

Tube lineup in receiver or transmitter?

Is the 6146 original, or was it a later modification? A lot of
the older low band units used an 807, and I've seen some that
were modified to take a 6146 instead. Not sure if Motorola
ever "officially" did that.

The same with the AC supply, is it a modification, or was it
factory built that way?

How big is it? Dimensions of the transmitter and receiver unit?

Possibility of a picture?

No matter what it is, I hope someone would endeavor to restore it
rather than part it out,

But............

I am in the process of putting together an AN/VRC-2, which is
a low band "coffin box" set built for the military. I have the
receiver on 29.6 and have the transmitter tuned up on 29.6, but
using signal generator instead of a crystal. I am going to try
to use one of the QRP Labs ProgRocks as a crystal substitute.

Biggest item I need to finish the set is a bottom plate.
I'm pretty sure the transmitter and receiver plates are the same.

The other issue I have is that I have a close to period
correct Motorola speaker, but it is square, and not round.
