I've recently acquired an AN/URQ-10 frequency standard and would like to borrow a manual to copy (or pdf to download). NAVSHIPS 0967-053-7010 This gadget was used shipboard as a master source for synthesized radio and RATT gear such as AN/WRR-2, AN/WRT-2, R-1051/URR, AN/UCC-1, etc. http://www.navy-radio.com/freq-equip.htm thanks, Nick K4NYW
