Title: Spectronics DD-1 Schematic Post by: KF9CM on July 25, 2007, 02:10:25 PM I've already Googled this and no luck, except for the operators manual. Does anyone have a schematic for a Spectronics DD-1 series frequency Display? I'll take a DD-1, DD-1C or DD-1T

They never issued any service related document. QST had a review of the DD-1 in 1974. However, I'll willing to bet you can take a typical early to mid 70's designed frequency counter and you would probably have most of the same circuitry. The main differences would be in the interface circuitry to the particular equipment.
