Re: [time-nuts] AN/URQ-10A standard docs
The URQ 10 was a reference that drove a distribution system that then provided the receivers and transmitters with a very stable reference. These were used with the T827 and R1051 synthesized radios. If the radio was off by 1 hz something was wrong. If the signal wasn't heard it wasn't there. Not because the radio was off frequency. On the ship I was on we had 3 HF 2KW +transmitters and 20 R1051s. Circa 1973. A r1051 at the time was $27,000. These radios did have a oven reference that was ok nothing like the URQ10. One of the maintenance procedures was to zero beat the internal to the external reference every month. Just in case the URQ 10s went missing. Thats my bit of history.

I'm guessing for tweaking the frequency of radios as their crystals drift. How many radios does a WW II battleship have? How many after various upgrades? (The URQ/10 manual said 1966.) Does it matter if a radar set drifts off frequency? I'm assuming that the transmit and receive side would be locked together. -- These are my opinions.

Hi, Go to www:navy-radio.com/freq-equip.htm. A complete manual including schematics for the AN/URQ-10A resides there.
