Title: T-504 Test Set Can You Identify THis Mystery Rig Post by: AB3L on January 18, 2012, 08:11:41 PM I have looked around some Mil equipment lists trying to find out what it is and what this might be good for. I have been offered two of them, both not complete. It has a video jack as well as rf in. It is housed in a brute force military enclosure with a screw on cover. The boxes are about 20 inch by 20 inch, maybe the same depth. Anybody have any idea what these are? The old professors bought a lot of mil surplus for their labs. This Doctor died a few years ago so I guess his supply is gradually being sorted thru and tossed.
Thanks, Bob Title: Re: T-104 Test Set Post by: Opcom on January 19, 2012, 08:31:43 PM Pictures?

Title: Re: T-504 Test Set Post by: W7TFO on January 20, 2012, 05:38:24 PM We sure build beautiful equipment in this country when we want to.
That look to be very application-specific, so may best be reduced to components and used again. 73DG Title: Re: T-504 Test Set Post by: K9PNP on January 22, 2012, 07:39:09 PM This one really got my curiosity up. Looked through every old [1965 and earlier] reference I have on old military equipment. There is nothing in the Army or Navy references. Air Force references after 1950 are short here, so not much help there. I'm beginning to wonder if it was a DOD item or not.
It is interesting that it apparently belonged to a 'laboratory' from the front panel stamp. Either that, or some lab had done work on it. Also, the fact that the transmitter and receiver have 'arm' switches is rather different. Almost makes you wonder if it was for an R&D or prototype item for some high energy device.

I do not find it in my Jane's here. Title: Re: T-504 Test Set Post by: Rob K2CU on January 27, 2012, 12:26:30 PM Probably a radar test set....L band.
Title: Re: T-504 Test Set Post by: W3RSW on January 27, 2012, 06:50:14 PM Hmmm, "clearly" stamped Atomic (?) Physics Laboratory in yellow.
And yet it has a 2C39 beast and tumble cavity decent to. Low freq. crystal Osc. Curiouser nd curiouser. Title: Re: T-504 Test Set Post by: WD8BIL on January 27, 2012, 07:11:52 PM Quote 2C39 in a cavity? Might be a 6161. Hard tellin'. Title: Re: T-504 Test Set Post by: AB3L on January 29, 2012, 05:16:49 PM Maybe a R-390 will bolt into the rails.
I can check back there tomorrow if there are any requests to look into. Maybe I'll grab one and take it back to my shop at work where I can investigate more. I would hate to trash anything that is significant. Title: Re: T-504 Test Set Post by: Jim, W5JO on January 29, 2012, 05:30:14 PM Atomic and Plasma Labatory. Could be from over near White Sands or Los Alamos.

I do not find it in my Jane's here. It has a ML-2C39-AM in the cavity. The lid has breathers on either side with tubing fittings inside directing to brackets that look to have held bottles or cylinders of some sort. Also has a 1kc frequency standard in it. The work on this thing is amazing from the harnessing to the hardware. Even has the hard to find original tuning tool..... ARO and MAB lettering with the Atomic and Plasms Physics Laboratory labeling. A tag on the back says it went thru Letterkenney Depot. |
