[time-nuts] AN/URQ-10A standard docs

[Walter Shawlee 2]

Does anybody have the manual for this old standard?  mine works, but is 
a bit high, and needs internal adjustment, and a new battery pack.  
pretty good condition for this old unit, and the 5MHz output is only 
4.8Hz off after heaven only knows how many years in a dark corner. it's 
only been running for 12 hours, so it might drift in after 30 days at 
the oven temperature, but my offset adjustment is maxed out.

I have had good luck converting the older 5Mhz standards to 10Mhz using 
a cheap chinese doubler board off ebay and a 10Mhz bandpass filter. the 
results were great (although about 6dB down from the original level), 
and made them a bit more useful around the shop as an external reference.

Any PDF would be appreciated.  All my web searches were total dead ends 
so far.
all the best,
walter
