4. OCXO 10 MHZ reference clock

OCXO was purchased from one of Chines Ebay sellers for ~30$, I mounted it together with power supply IC on simple wire-up PCB. This solution is perfect functioning and has nice stability, what else I need? There is only frequency drift after power-up till reference Oscillator’s Oven heating up to needed temperature. This OCXO has frequency voltage control input that is not used by me present time that can be used used in the future for GPS base frequency looking/calibration.

 

I’m finishing on this point..
