[ARC5] UHF Aircraft Radios Giveaway

[Mike Morrow]

Welcome to the list, Nick.
 
FWIW, the AN/ARC-57 RT-unit that I own has a tan front panel and no case because it mounted in a shelf that was part of the aircraft.  It has nomenclature plates on the chassis, but no JAN nomenclature plate that says "ARC-57" on it.  It was part of the B-58 Hustler, not the B-57 Canberra.  Interesting unit, not many made.  Did you get yours to work?
 
I'd be interested to know if your unit had a JAN nomenclature plate...just for comparison.

My first post here.
 
I started monitoring UHF (and VHF) aircraft coms when I was in junior
high.....and just never stopped. Kelly Field (San Antonio) was always a vey
busy place in those days. My first job was at Kelly in 1962 as an
engineering intern designing the depot level avionics repair facility for
the B-58. Over the years I've collected a few MIL UHF radios that will
either go to someone who will love them or metal recycle.......I'm moving
from Austin to Tulsa quite soon, packing like a maniac, trying to get
light(er).
 
Radios:
ARR-39. A receiver used in a G/A data link to provide intercepting pilots
data on the unidentified intruder. It is a repackaged ARC-34?(the
transceiver that used submin tubes)receiver that used an external power
supply. Two available....one converted to 6V filaments and a home-brew
control head. Fun toy!
 
ARC-57. I think this is the UHF radio used on the B-57. No case, but
otherwise intact. The cooling air inlet is ~1/2 to 3/4 diameter so obviously
they used cooled bleed air from the turbines. I think it must have been
bleed air because the weapons officer's radar display, which used a couple
4CX250's as deflection coil drivers, the radiators of the tubes would melt
off the tubes, slide down the tube body and do grievous harm. It was a
common problem when one started the radar before cooling air was available.
Have the control head, no manuals.
 
ARC-53X. Someone lifted the 243 Mc monitor receiver......maybe another
module missing....I don't remember. I MAY have the manual???
 
ASQ-19. A repackaged version of the ARC-52/53 (???) used on RF-4's operating
from Bergstrom AFB in Austin. I found parts of what must have been a test
bench at a junk yard that included a UHF control head and a cable that fits
the radio. The PA tube (metal ceramic) is missing. Power supply for the ASQ
system was external. Have full manual....copied.
 
APX-6. Fresh from SAAMA depot. Not much else to say, but it IS clean! Kelly
was the depot for these boxed in 1962!!! Original manual.
 
APX-7. An airborne interrogator for above. Modern compared to the
APX-6.....like crystal controlled. Use unknown......maybe refueling ops?
 
No charge, but no shipping. Too busy packing.
I am located just outside of Austin.
Must be gone by ~April 8th.
