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,
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,
Timing grade Motorola Oncore GPS's are availble cheaply on ebay.

Hi.....has anyone experiemented with programming a PIC to get 10khz out of 1pps GPS pulses ? If so, maybe a link or two please , or some info .
