[ARC5] AN/ARR-47, AN/ARC-48

[scottjohnson1 at cox.net]

All-

I have two pieces of equipment that are undoubtedly rare, one might even be
unique.

 

The unique one is an ARR-47, which was removed from a C-97 by me perhaps
fifty years ago when I was a lad.

It is a transistorized (very early Ge transistors) BC band receiver, with
four pushbutton presets. It resembles a very high-grade auto radio, with
permeability tuning, and a preset mechanism similar to an auto radio.  Four
digit odometer type digital readout.  It is very compact, Dzus rail mount,
only 2 ½” High, and 5 ½” deep.  Powered by 28VDC, with line level audio out
via a 7 contact Winchester type plug.  Antenna connection is a BNC.  The
Aircraft it was removed from was a SAC command aircraft, which may have been
assigned to Gen. LeMay, but I am not certain.  Manufacturer was Sparton.
Question- Does this little receiver ring any bells, especially to old SAC
warriors out there?

 

The second radio is the ARC-48. Which seems to be a very early 4 channel UHF
radio that was installed in H-1s and perhaps other early light helicopters.
It is very compact, output about 1.5W and has 3 crystal-controlled channels,
plus a guard channel at 243.0, The frequency coverage is 235-290 MHz.
Receiver is a regen, and the same circuit serves as TX, this is repeated 4
times, with common audio circuitry.  Miniature and sub-miniature tubes,
power is from an ARC-5 receiver type dynamotor. Completely self-contained in
a 12” deep x 5” wide x 8” tall case.  Manufacturer was Telephonics Corp.  I
have a preliminary factory manual, but I would like to know whether it was
used for training aircraft or might have seen use in Korea.  Developed
around 1951.

 

Any information would be very appreciated!
