AN/GRM-122 Radio Test Set . . .Parts Shortage Looking Grim

The AN/GRM-122 is the main radio test set used for all SINCGARS, airborne radios and aviation platforms. Unfortunately, some of its parts are getting much harder to find.

So a major repair effort is now underway to fix as many of the AN/GRM-122’s AEROFLEX components as possible. The repair contract runs out in Aug 2016, so check your shops now for any of the following components:
