- This video covers 10 things you gotta know about the amazing TA-1/PT military field telephone from the 80's and 90's:
1). The system is voice powered / no batteries required to operate
2). Voice is transmitted and received with Carbon Transducer mouthpiece and earpiece
3). Because no powered amplification, these work pretty quietly
4). 4 mile range over two-wire WD-1wire
5). Each unit has a generator to ring other line (80V)
6). Volume control on the bottom of the unit is for the ringer volume only
7). A yellow call indicator provides visual alert of incoming call
8). Daisy chainable with multiple units
9). Half-duplex communication -- only one person can talk at a time
10). Comes with a rugged carrying case for transportation

When I was in the army, those were usually carried by the wire commo guys for testing the wire runs they pulled between locations.....everyone else had TA-312 phones.
I have a couple of the TA-1 models and several TA -312s and even the switchboard with the headset.
I just bought a TA-1/PT! I only have one and hooked it up to a TA-312 to test. When I am communicating from the TA-1, I hold down the push to talk button during the whole conversation. If I let off to listen I hear nothing. I thought this was push to talk, but mine works like a regular phone if I just hold down talk button. Is this normal between these two phones?
@Christopher Williams I'm stupid. I discovered my TA-1 was missing the receiver. I got one from Ebay and have a fully functioning field phone that does communicate just fine with the TA-312.
@Christopher Williams I don't have a switchboard. Wish I did. Maybe someday. I bought my TA-1 on Kijiji from a private seller in Manitoba Alberta. He only had the one.
thank you on the tip mine sound much better now, I heard they could 5 miles with the proper wire , 4 is still a pretty good distance, plan to use them on a ranch
I have a pair of these and to get them to work, you have to hook them up and then send a 80 volt ring charge to each unit. I think that wakes it up. If you just hook them up and try to talk, nothing happens (in my case) so a quick ring and they become operational.
More on ta1 excellent video thanks give use more
We used these in the Fleet Marine force back in the 80's
A good thing! Looks like the Soviet TA-57, characteristics I do not know, but it looks like. Interesting video, thanks!
They came out in the 60s i have a unissued set of 1968 dated ones.
Other than that, very good vdieo!
The microphone used is not a carbon microphone. This is because it's a voice powered system, and carbon microphones need an external power supply (either DC line voltage of a battery).
Dynamic microphones generate a voltage when you speak into them - carbon microphones only vary their resistance, but don't generate voltage.
Very well explained.
Can you buy a modern version of this to outfit a retreat?
Can these talk to a ta-312 ?
I made a lamp out of one just like that
