Re: [time-nuts] US Army Frequency Standard
Well done Ziggy, I for one am grateful for your efforts, I commented previously on the high standard of construction but I couldn't believe that the angles of the screw slots at the corners of your schematic are identical to those in the lid of my TS65!

Re: [time-nuts] US Army Frequency Standard
Amazing, the things that can be picked out of the noise. I have one of these frequency standards, but it belonged to the US Dept. of Commerce, during the period 1965 to 1970 when the DoC was given the weather bureau, named Environmental Science Services (ESSA). It was last calibrated 9-27-72, after ESSA became NOAA. The schematic on the cover of the cable box, inside the door, has the schematic for "Frequency Standard TS-65C/FMQ-1" The box contains two cables, one with a PL-259 and one with a BNC connector. The name tag says "Type 2509-2 Ser 140" made by American Time Products in New York, licensed under Western Electric patents. ATP made timing chart devices for setting the correct rate for a wrist or pocket watch. Google has nothing for ATP, but a search for "TS-65C/FMQ-1" has one by Newton Time Products, which had negative search results. My device works, 60 Hz reads 60.06, which is 0.1%, but the 10 and 20 Hz ranges unaccountably have no output. Abe Books has a manual for $5. Since I'm cleaning out, this mechanical marvel is yours for the cost of shipping 24 pounds in a 12x12x20 box from Minneapolis 55438. It goes on the scrap truck Thursday if no one wants old stuff, as usual.

Re: [time-nuts] US Army Frequency Standard
Thank you everyone for your comments, and if I've got it right Brooke, if you paste this into your browser: http://www.flickr.com//photos/75ohm/sets/72157629019710615/show/ you should get a quick tour and a movie! This is indeed a tuning fork driving a synchronous motor that has a perforated disc on its shaft. The whole unit operates as it should and the quality of manufacture is superb, so I'm reluctant to pull it apart but I am curious as to the type of photocell it uses. It seems very small and the dates on many of the components suggest manufacture in the mid to late 1950s so what was around to do the job at that time? There is no cathode bias on the "voltage amplifier" that it feeds which suggests it s Photovoltaic rather than Photoconductive. Thanks again for your replies, John H.

Re: [time-nuts] US Army Frequency Standard
If it is the instrument I remember, the tuning fork was used to generate the drive for a synchronous motor. The motor drove a disc with hole patterns at different radial positions. The frequency control moved a photo cell assembly to pick off the different frequencies from the disc.

Re: [time-nuts] US Army Frequency Standard
It appears to be a Test Set for the FMQ-1 Radiosonde Receiveing system. Radiosondes used audio tones to encode temperature, pressure, and humidity as audio tones and transmitted those tones to a ground station where they were demodulated and recorded. Interestingly, this thing apparently used a tuning fork to run a synchronous motor with a disk with holes punched in it to generate the tones. I've only been able to fing the -24P manual, which is an illustrated parts list.
