The TA -312 Field Phone (LEGENDARY) WE CALLED THE BATTERIES BA 30S
The analog, 2-wire, battery operated TA-312/PT replaced and will interoperate with the World War II and Korean War EE-8 field phone. The rugged and reliable TA-312 was used from the 1950s through the 1980s before being superceded by the TA-838 analog field phone. TA-312's continue in use throughout the U.S. forces as well as many allied countries.
The TA-312/PT is a two-wire, battery operated field telephone. It has a
range of 38 km using WD-1 wire, and was a successor to the EE-8 field
phone used during World War II and Korea. Primarily used from 1950-
1990, it was replaced by the TA-838. It's typically stored in a canvas
bag. An optional TA-955 dual tone multifrequency (DTMF) adapter
allows push button operational interface with automatic analog switches.
To install the TA-312 telephone:
* Strip away one-half inch of insulation from each strand of the WD-1
wire line.
* Depress the spring-loaded line binding posts and insert one strand of
the wire into each post. It doesn't matter which one goes where.
* Adjust buzzer volume control knob to LOUD.
* Turn the INT-EXT switch to INT (Internal). The TA-312 has the
capability of either using the standard H-60/PT handset (INT) or an
external H-144/U headset (EXT).
* Turn the circuit selector switch to LB. (Local battery).

* Insert the two BA-30 batteries into the battery compartment (one up
and one down). Two D-Call batteries work just as well.
* Seat the handset firmly in the retaining cradle.
* Turn the handcrank rapidly a few turns. Remove the handset from the
retaining cradle and wait for the other operator to answer.
* Depress the push-to-talk switch to talk. Release the push-to-talk
switch to listen.
The Technical Manual used for the TA-312 is TM 11-5805-201-12.

Originally a 31N before going on to medic and nurse. This field phone rarely worked, was so heavy and occasionally shocked me!

The EE-8 was what I was trained on in 1951. Laying a land wire line that was easily taped into or cut wasn't the smartest move in combat, I felt.

DIVARTY barracks had one going from the CQ desk up to the female floor. That was a couple years ago. Also a staple on our section MTOE.

You certainly know your equipment!!! I actually saw one or two in Basic Training in 1983! Think part of our EOC test was communicating utilizing this device and the appropriate com communication! Great Share! Impressed with your knowledge!

I used the ta-312-pt to communicate from the radar set to the control tower in 1966. Now I use
the field phones with my 2 great grand sons

It was still 31L when I was in. I wish I had more old pics of running cable, installing and repairing phone lines, gaffing equipment and climbing poles, cleaning the cable and the reels etc. It wasn't easy work but I enjoyed being able to get outside and get dirty. I only wish there had been better job opps when I got out. Thanks for this pic, Miss those days.
