Hi Ashley, Reading between the lines, are you trying to subsitute a 1pps output GPS for use in the G3RUH 10kHz GPSDO design? If this is the case youwould be better off "biting the bullet" and going for a design that uses 1pps directly. An example is the classic Brooks Shera design, http://www.rt66.com/~shera/index_fs.htm While it's simple to build, there are limitations to the G3RUH design. Adding extra circuitry to generate the 10kHz is most likely to degrade the perfomance. A good overview of GPSDO's can be found here, http://www.ko4bb.com/Timing/FrequencyReference.php Timing grade Motorola Oncore GPS's are availble cheaply on ebay. Regards, Robert G8RPI.

If so, maybe a link or two please , or some info .
