I just got home with a ''radio'' of sorts. A friend of mine called Me and asked if I wanted an old radio that has been partialy parted out after He heard that I was going to build an EDM. I said I'll be right over , thinking I'd find a couple of boxes of various gear.
Well it was more than a couple of boxes to say the least.

It is about the size of a small truck-bed style camper:eek: I don't know exactly what I have except it is old and incomplete and diss asembled. I have about a hundred printed circut boards ,at least three power supplies and some racks of tuning ''stuff'' that looks to be intact.
Of course it is all weird 400 cycle power .

I don't know much (if anything) about the workings of a short wave ,but there are a few pcbs with crystals about half the size of a cigarette pack on them. So befor I start shlt canning stuff that I know that I'll never use,are any of the components like the crystals in it of any value to any one? Or is it mostly scrap?
The radio cabinet has been 90% gutted and is still waiting for Me to move it this weekend. It looks like it would make a nice one man hunting shelter, it has a wall mounted heatpump and looks to be weather tight.

Pictures!

There's lots of stuff that is hard to get now like variable caps, variable and fixed inductors, fun stuff for making antenna tuners, frinstance.

I know, I know, it was raining and getting late. I'll try to shoot some pics Tuesday.

Did you get the S250 Shelter? looks like a mini camper...

Many different sets/kinds of radios/teletypes/crypto went in them..

PC boards means fairly current 60's or later..

Wow! Sounds like you have been gifted a COMEX. Those slide in communications shelters are really neat to make into a mobile ham shack. Some of my friends are big into public service communications (ie: hurricane emergency operations) in which they have to go to an effected area after the storm passes and set up basic communications. Before retirement, when I still had money and could afford to volunteer, I would have loved to got my hands on one of them. I have the M-715 Jeep truck that would haul it. Oh well, I am not up to all the hardships any more that are a part of being on a jump team involves. Still, there are lots of good things in one of those units. Contact the local ham club and you might be able to sell or give away the stuff you don't want.

WOW, that is a signal jamming set, and with lots of the goodies still intact...

Will also send normal HF transmisssions too..

Must've come from the Army Depot or McClellan. Everything protable in the military runs on 400hz. All of their gensets are 400hz. As far as scrap goes, all the conductors and coils in the RF section are silver plated. They used pretty thick plating. I'ld bet any PA tubes would be sellable. Or you could make one heck of a linear amp for your CB! There'ld also have to be a ton of copper in the wiring. Lots of wiring in a shelter. I used to work on'em.

Those glass doo-dads with the copper bellows in them, in the first photo, are vacuum variable capacitors. They are quite sought-after by ham radio folks building high power amplifiers, tuners and transmitters. They can fetch a fair amount of money from the right buyers. They are very costly if purchased new. You may be looking at a decent "new tool fund" with all of that stuff right there...

Nice score!

The Air Force and Aircraft use 400 hz (less metal required for motors/gens = Less weight)

The Amplifiers are worth plenty left alone, and sold complete. Quite usable as is with a new power supply added... Or just hooked up to a dirt cheap 400 hz Mil Surp gen set, that no one can use...

Some of the monitoring and jamming gear will go for nice $$ to collectors..

(mostly old guys that used to run the stuff)

Yes the bits and pieces can be sold off, but that is a VERY special unit... Not that many made, and fewer yet sold complete...

Depending on whats in that, I bet almost a new Bridgeport worth of gear...

I opened up a few panels and had a surprising look around, evidently all of the circut boards were not spares they were pulled from every slot that could be pulled. And it gets worse from there. several bundles of wires have been cut and removed. It looks like the only thing not messed up seems to be one power supply and the little scope thingy.

I don't know if some of the dammage was intentional by whoever abandoned it originaly, or if it was vandalized ,or a combination of the two:mad: .

The vacuum variable caps have all been carefuly removed along with some other fragile items:) .

So I'm thinking maybe a new Bridgeport handle or two:D

Most equipment of that type is supposed to be "de-militarized" before it leaves government control.

Most things prepared by the military for public use that I have seen is very obvious, hammers and axes type work . This was more subtile ,it looked good on the surface no dents or gashes or even broken meters or knobs (kind of what ya see on flea-bay) but the inside tells a whole different story.

Those vacuum variables and what I believe to be a vacuum switch
would have been worth a small fortune in the 1950 to 60 when
I was building high power transmitter. The printed circuit bds. though
date it fairly recent.

Lew, I have not found a ''born on'' date yet. But I did find a brass plate that states it was overhauled in the mid 70's in Texas.

I was admiring those, too. Makes me wonder what the final amp is in that bad boy.
