of Henry Radio.. yes, the amplifier or transmistter was a common Ham
unit with a new paint job and military style knobs.

Several pieces of gear, Henry, Collins, Drake and more, came in civilian
and military versions. The only difference was the olive drab paint and
the military style knobs and an "A" for Army (or some other designator
to indicate the cosmetic differences)

As recently as Viet Nam they were still using ham gear in the Military.
� Good Solid KWM-2's in fact

The Collins KWM-2 (all-frequency-band maritime version) was used for
MARS under the AN/FRC-93 designation through the Vietnam War. No
change in color or knobs or much of anything else. For reference, see
TM 11-5820-554-12 for the "set-up-and-operate" TM. This is essentially
the Collins document under DoD wrapper. Date of TM is June 1976.

There have been a great number of civilian fixed station equipments that
have been designated as "military" (by the addition of a sticker/label)
as far back as 1953 without any special tests, physical or
electronic, without any changes or additions in appearance. None of
these were intended for field use up to about 1980 or so, therefore they
would not have undergone full environmental testing. Consider them
"COTS" (Commercial Off-The- Shelf) equipments as described by Hans.

Those of us who have served in the USA military usually
define "military" as those equipments which have gone through full
environmental testing and are used in the field or afloat. MARS is not
normally part of the standard tactical communications used by the
military even though such equipment may have military or NSN (National
Stock Number) designations for procurement purposes.
