This could have been either an AT-7 or AT-11, both advanced training
aircraft based on the Beech 18 airframe.  They were used for
navigation, bombing and gunnery training.

Yep, it do.  While the SCR-A*-183/-283 was incapable of CW reception
without an external BFO like the BC-**-183, a key button was still
present for CW (MCW?) transmission.

The TCS was widely used in a number of installations including LTA
patrol craft.  It was/is a pertty neat - and versatile - rig.

Dunno about tanks (Did the Corps have Shermans?) but the GF/RU was
used in Marine SP guns.  Robert, check me on this, but I think it was
the GF-11/RU-16.
