WW II US Army Air Force – T-30 V THROAT MICROPHONE – TANKS & ARMORED VEHICLES

The T-30 throat microphone was a commonly used tank microphone and a standard of the US Army Air Forces in WWII. This carbon microphone was strapped around the wearer’s neck, with the two 1-inch round pickups made of black rubber contacting the wearer’s throat near their Adam’s apple. It was anchored around the wearer’s neck by an elastic strap. These pickups transmitted vocal vibrations as the wearer spoke allowing speech to be heard over background battle noises.

The T-30 microphone had a two-pronged PL-291 plug, which was connected to a JK-48 jack on a SW-141 push-to-talk switch.  It was produced in over twenty variations by different manufacturers, indicated by a suffix code letter.
