Default Cold War Field Telephones

So, you've got yourself a settlement but the nasty OPFOR are monitoring your hand-helds? No worries, here's something to string between your bunkers.

Field Telephones.

Battery-powered hand sets appeared to all be able to run of external power, usually in the 3 volt range. Most phones seem to have a hand crank to enable ringing at the other end if not used with a switchboard. Nearly all these phones, you can probably assume it is all of them, are sound-powered. The only reason you need to use power is to ring the buzzer. If you don't have a dedicated switchboard, and let's be honest you won't, a simple task will be to rig up a series of switches that exclude or include lines for multiple use. In this case it's possible to have "party lines" of multiple phones.

One of the cool things you can do with field telephone is find an isolated barbed wire fence (they're all over the place in Texas), set up a prearranged time, hook your wires to the fence, unless there's break in the wire, you can easily get a signal to carry up to 5 miles or more, Start with the bottom wire and work up at a given interval until both sides have connection.

Just an FYI, having used the TA-312s a lot, you do not need the batteries, they just make it work better. With out them you still get a signal (just weaker), and it will still ring (just quieter). with out the batteries they are a it worse then the TA-1 (also used it a lot), but we used them lots with out the batteries. I believe that where it becomes a issue is when used over very long distances. I have never used them over more than a single spool of wire or two at the most (1/2 mile or less). I have never used the TA-43n so not sure if it is the same or not.

They're identical except for the EXT/INT switch and U-79/U Connector, which the TA-43 doesn't have. Some of the TA-312s were rebuilt TA-43s.
