Correct, Dan- nothing received-still interested though, if something pops up. 
Unit is still here and a friend has a sidereal version but no data.

Subject: [time-nuts] Datametrics SP-100 Time Code Generator

Hello,

I'm looking for a schematic and/or service manual for a Datametrics SP-100, a 
1970s-era rack-mount IRIG time code generator.  According to the Time Nuts 
archives, Dave Brown (ZL3FJ) was looking for this information back in 2005 but 
as far as I can see received no reply.  I have found references to its use in a 
timing distribution system but haven't found service information that would 
allow component level repair.

Does anyone have, or know of a source for, technical information on this unit?


Thanks!


Cheers,

Dan

Re: [time-nuts] Recommendations for Mains Power Monitor / Logger (

Here's a couple of shots of a Venner version of a similar clock -a combined 
synchronous motor movement  and pendulum.

A friend of mine has it. It was used in a power station environment up until 
only a few years ago. He paid a lot of money to have it restored.   It is 
apparently quite rare.

Year ago we used to sell a quartz clock and a 60hz clock mounted on a panel for 
generator stations on small islands in the Caribbean.

This is the way it was done in the 1930's

Ditto- still chasing a couple of guaranteed good 12 GHz ones at reasonable 
rates.

Scott,

Do you have any plugins for the 5245Ls?
