Anyone have info (a manual would be ideal!) on the early 1960's Manson RD-180A quartz oscillator? Hallicrafters bought Manson Labs, apparently during this instrument's production period so some later units are labelled as model CFS-180A and branded as "Hallicrafters / Manson Laboratories Division". Double-ovenized, oscillator AGC, and built-in battery bank to survive power outages. I have acquired a working RD-180A s/n 97 having the standard 1 MHz and 100 kHz outputs but 5 MHz out was optional. A very basic description was in the New Products column in Electronics of July 13, 1962. Later advertisements give a price of $2,400 and claim the instrument was used as a standard for "the Pacific Missile Range". David Frank VE3DMU FN25cg
