[GPS_Standard] can't get frq std to lock

[Bert, VE2ZAZ]

Hi Talmadge,

My website provides two sets of parameters as a starting point. You should
have no problem disciplining an OCXO with these parameters. First implement
the "System in Initialization" parameters. This should bring the system to a
lock. Then transition to the "Stable" condition parameters. The system
should stay in lock.

What oscillator are you using? Did you set the tuning slope (X) parameter to
match you OCXO? What GPS are you using? Does its 1PPS signal have a 5V
swing? How clean is your 5V supply? These are the most common reasons for
problems. I am quite sure that it is something simple.

Regards,

Bert, VE2ZAZ
