[ARC5] R-24/ARC-5 - Yet Another Mysterious Function

[Scott Johnson]

This reminds me of another oddity.  I can't put my hands on it right now,
but I have a small Dzus rail mount receiver, with 4 or 5 pushbutton presets,
that appears to be nothing more than an airborne AM entertainment radio.  It
has an AN/ARR-xx nomenclature, looks to be late fifties solid state, eight
transistors, line level audio out.  Tunes 550-16700 kHz, same panel size as
a 618T control box.  Anyone ever see one of these things in service?  It has
a permeability tuner, and the pushbutton mechanism looks to be automotive,
but it is built to very high standards.

In the B-29 Combat Manual I have they mention that a certain number of
B-29's were equipped with the optional low Freq (O-16 and O-17?) oscillators
so that they could transmit signals that could be picked up by ADF receivers
carried in all of the aircraft.  This enabled some aircraft to serve as
beacons for rendezvous purposes.

Like Mike Morrow, I have wondered for some time why the ART-13 would need
that LF capability.  This is one explanation and might be one reason the
ARC-5 MF sets were built.
