Dear Half-Mast,
Part of a good PM program for the SINCGARS radio system is testing
for power out and reflected power between the radio and the antenna
matching unit using the AN/PRM-34 test set, NSN 6625-01-094-
5646.
Unfortunately, this test set is no longer being made. Someone told me an
AN/PRM-35 would soon be available. Is that true? If not, what can we use
to make this critical power test?
SGT P.T.M.
Dear Sergeant P.T.M.,
You’re right about the AN/PRM-34 no longer being produced. However,
production of the AN/PRM-35 was cancelled due to changes in requirements.
All is not lost, though. Agilent Technologies, Inc., has made a substitute called
the PRM-34B. This new
tester provides the same functions as the PRM-34, but is
fully automatic. Just hook it up and turn it on and it makes all the measurements
simultaneously. You can check out a radio and antenna in less than 30 seconds.
The PRM-34B can help in Feld troubleshooting other tactical radios if you
tune the radio to operate in the PRM-34/SINCGARS radio spectrum (30 MHz to
88 MHz). The PRM-34B is much smaller than the PRM-34 (it Fts in your cargo
pocket) and uses the BA-5372 6V lithium battery, NSN 6135-01-214-6441.
You can order the PRM-34B as an off-the-shelf item from GSA for around
$3,500. Go to the GSA website:
Once there, enter PRM-34B in the search Feld and the ordering
info will come up.
A New Test Set
for SINCGARS!
Here’s
the new
test set!
Put your
SINCGARS

Are you
ready to
pass my
test?
I sure
hope so!
me,
too!
