Making Amplitude Modulation GREAT Again!


« on: April 06, 2017, 09:48:12 PM »

So, I scored a big pallet of stuff for little money and a shit ton of shipping :-)

I'm going to post some pics of what I got.  A LOT of this is boat anchor.  A LOT of B&W miniductor, an entire box of oil filled caps, a bunch of plug in coils, full set of matching Westinghouse meters, etc.

I do not know what it all is.  So, I'm hoping people can take a look see, and maybe figure out what it is.  Like, the full set of Westinghouse meters (freq, 120 volt AC and 300A AC meter and shunt!....  But I've no idea what the other 3 Westinghouse relay looking items are.

Also, if someone sees something they need, speak up.  The stuff isn't for sale, was purchased to help my junk box, etc. But, this board and its members have helped me, and I hope I can give back.

Anyway.....  Here's the first load I brought home.

I'll take a better pic of the relays later.  I'm wondering if they aren't time delays or timers of some sort.  They do have a dial inside you can set.

Definitely some shelf queens lol!

This entire purchase came from a 7 land SK in the Reno, NV area.  I've no idea who, purchased from. An estate sale.

It does have the box for a 4cx3000, but alas, the box contained a HUGE variometer.

That 'K' series Westinghouse AC ammeter wouldn't use a shunt, rather a current transformer with a ratio of 60:5

The relays most likely are overload jobs, with an adjustable range.

Manly overload relays for manly transmitters!

How huge a variometer? Those are good for loading adjustments but not so may people know how to use them and they have definite frequency ranges.

Dennis,

Your exactly right, and I have the CT for the meter! I was stoked to see that included in the box.  There are also at least two Weston (edited because of autospell mangling) box type meters.  All in all, between 1.6k lbs and a ton.

Looks like the relays are timers.  I popped one apart (they have screw on fronts, behind glass!  BUZZARDLY!!!

Pat

The variometer is receive only.  Wrapped with a huge amount of wire, I'm guessing LF is what it came from.  It's in a box still at work.  Have a forklift there, cheaper on freight shipping, but then I have to pack rat it home a couple boxes at a time.

Need more shelves.


Pics enclosed.

I'm not real hip on the older military and other anchor equipment, but I do know some takes plug in like these...  Hence why I said if someone needs something, say it...

  The stuff in your first pictures looks like it came from an old substation, the relays look to be old fashioned protection relays. I remember a protection technician I worked with showing me some of the protection relays that were used in an old substation, the stuff was made in the 1930's but looked new and had been in service for 70 years. This was about 15 years ago, all that stuff has since been replaced with modern equipment.

 That old stuff was good but if there was a fault resulting in a trip there wasn't a way one could analyze what had occurred, the new stuff logs the info and you can download it onto your PC, progress!!!

S,

You may wish to consider disconnecting one side of the B&W coils, or more to the point, unscrewing and  lifting. The plastic coil separator has a habit of "drying out" and shrink, thereby cracking the ceramic jack bar they are mounted to. Don't bother asking me how I know, you probably know how I know, you know.

kudos to you fer getting a nice stash. Your probably making Vortex Joe or Pat jealous.

I have that exact Westinghouse AC meter.  It has long terminals on the back.  I use it to meter the incoming AC voltage to the shack.  The amp meter uses a current shunt xfmr, hopefully you have it.  You need the one that goes with that meter.  Although the meter is not too practical because of the 300 amp range.

You keep collecting stuff like this and it won't be too long before your QTH will look like mine.  Wall to wall parts and pieces.

Never had me a modulation transformer....  Not anything worthwhile, at least.

Guess it's time to build a plate mod rig.

Any ideas for tube lash up?

(edit) OK, I get the 2400 ohm output is the rf stage, right?  The 600 ohm windings are for a speaker I'd assume (placing this in a txcvr not just a TX, and the altitude rating I'd say possibly aircraft)..

What would the 50v output be for? Would that be a 50VAC output at full modulation....  Mod meter or mod light?

Shane,

   I think that mod transformer was used in a UHF AM transmitter. The modulators were 811's. The turns ratio is fixed, but impedance wise it will scale up or down.

I used one of the exact transformers in the 1980's. With a modulation choke to carry the DC current, and a 4uf coupling condenser, this transformer was wonderful. I ran a quad of 808's in P-P-P at 2250v plate, and made an easy 600 watts audio. The low end was strong down to 100hz or a bit lower. With a couple of big triodes in the RF, I ran 1 KW input (2500v @ 400ma), and had headroom for some nice positive peaks. I wish I still had that rig....put out an 850 watt carrier.. :-)

I remember using a resistor dummy load on the modulator, and running up the power for prolonged sine wave and music tests. That transformer never even got warm.

So the madness begins.  Luckily, I scored quite a bit of those cardboard parts holders we see at all the surplus shops, so that's helping with sorting and assigning.  

Spent yesterday building shelves into a shelving cabinet I had.  Made a dent.

I have meters.  And oil filled caps.  

And still have another box of oil filled.

Hoping to start on the wire wounds soon.  And rheostats.. Have lots of them!  

Good news on the transformer!  The only choke I have is small....  But at least now the transformer is begging to be used.  So many projects...  And when the most pressing project is sorting the stash 😀

 The West Coast Military Radio Collectors Group Meet is May 6th and 7th at Camp San Luis in San Luis Obispo you might enjoy it. They have a website or email me.
