AN/TRC-170(V)2 & 3…
Y
our radio terminal set AN/TRC-170
(V)2 or 3 needs a strong defense
against desert sand. Part of that defense
is having on hand a good supply of air
and gas particle filters. But some of the
filters in TM 11-5820-934-23P-1 and
-2 have changed NSNs.

GBS TGRS…
T
he global broadcast service (GBS) transportable ground receive suite (TGRS)
models AN/TSR-4 and AN/TSR-7 are being replaced by the internet protocol ver-
sions, AN/TSR-8 and AN/TSR-9.
Until this replacement is done, repair parts for the -4 and -7 must come from
you.
New parts are no longer being made, so old, failed parts must be refurbished and
reissued. This can’t be done unless you turn them in!
The parts needed most are components of the asynchronous transfer mode receive
broadcast manager and the ground receive terminal.
Here are the parts needed most:
