The RT-58/ARC-12 looks like a neat set. I've got the manual,
but not the radio. It used all the same support components
as the AN/ARC-1 did, except for antenna. I suppose the idea
must have been to be able to pull out the RT-18/ARC-1 and
replace it and the antenna with AN/ARC-12 units, leaving
rack, cable, and control box installations intact.
I remember Fair Radio was selling these in the mid-1960s.
I wanted one, but couldn't afford it or shipping on a junior
high school student's income. I've not seen one offered anywhere
since.

Which is exactly what, IMO, makes them "classic." The earliest
contract date I've seen on a RT-178/ARC-27 was 1952, so this RT
was one impressive piece of electronic and mechanical engineering
for its era. I know some were still flying more than 25 years
later. The common use of the AN/ARC-27/55 is sort of like the
AN/ARN-6 ADF, which also was found in almost everything that flew
during the -27/55 heyday.
I prefer the unpressurized version, the AN/ARC-55. It is a lot
easier to pop the top cover and admire the works inside than is
the AN/ARC-27.
Here's an unrelated question: What was the difference between the
AN/ARC-1 and the AN/ARC-1A? I've got manuals for both and I've
not been able to detect any difference between the RT-18 and the
RT-18A, nor in the remainder of the system.
