[Milsurplus] M-113 APC Radio?

[Bill Strangfeld]

It varied.

The M-113 ACAV at the Patton Museum at Fort Knox has one RT-524 and one
R-442 auxiliary receiver.  (AN/VRC-47?)  There is also a VIC-1 intercom
system (AM-1780 amplifier and various control boxes) which is hooked into
the radios and the driver, TC, and gunners' positions.

The M-113 antennas include one AS-1729 for the RT-524.  The AS-1729 has a
MX-6707 base with AS-1730 lower element and AT-1095 upper element.  The
MX-6707 has motor-tuning that works automatically when the RT-524 frequency
is changed.  There is also a fixed antenna for the R-442 which uses the
AB-15 (?) base and MS-116, 117, and 118 elements.

The M-577 command track at the Museum has two RT-524s (AN/VRC-49?) and a
VIC-1.  These are located on the left side of the rear compartment.  The two
antennas in that one are AS-1729s.  There are two more unused blanking
plates on the top armor deck which allow antennas to be added.

The M-577 also has brackets on the front left corner which permit the RC-292
antenna system to be installed when the vehicle is parked.  The RC-292 is a
field portable ground plane antenna on a 30 foot mast.

Both the 113 and the 577 have MX-7777 transient suppressors.

These appear to be the original systems in these vehicles (no leftover holes
from other radios) and they are working.

Some M-577s had GRC-106 sets with rtty installations.
