Re: [time-nuts] FS700 schematic
Paul, I am currently in a terrible hurry with my job. Must return to the FS700 later. Currently it runs completely ok on the W3DZZ with 102 dB receiver gain and 31 dB noise margin. I have connected the output of my Z3805 to the FS700's comparator input and the display says that ther is a delta-f of 1.9E-13 measured over a period of 117 hours.

Paul, You can do it in a common scanner in two parts, then using any graphics editor (i.e. Photoshop) rotate one of the files until they match and paste both.
