U-229

The U-229 type microphones are all dynamic types. Separate web page for U-229 Audio Accessories, U-229 Pin Out

Handsets & Mikes

Hint: It's very important that you check which handset you use. Some of these will NOT work with military radios as a handset!!! (guess how I know this). Some handsets are designed to work with military simplex (Wiki) radios and some are designed to work with duplex (Wiki) telephone systems. Still others are designed to work with cryptographic equipment. These three are not mutually compatible.

Bail Out Connectors (Aviation Headsets)

The idea is to have a connector between a headset and radio that will separate without any intervention by the person wearing the headset. They just get out as fast as possible and a small amount of tension on the cable causes the bail out connector to unplug. These are commonly either 4 or 5 contact plugs that are 0.281" diameter at the electrical connection shaft.
