[GPS_Standard] Using the VE2ZAZ Controler with an Robidiun Stadard ??

[Michal]

Hi Stig and All,

Loop control of VE2ZAZ design assumes either 1Hz or 10Hz tuning range 
depending of configuration setting.
Applying directly your Rubidium Standard  into 1Hz control means 30 
times higher loop gain and may even cause loop instability.
So if you will not get better advise, simplest solution is to use 
passive divider to change 1Hz/5V tuning slope to 0.03Hz/5V.
I have made same step with HCD-81 OCXO with far more than 10Hz tuning 
slope. If anyone needs details please e-mail me.
This is hardware solution.  How to set user parameters with Rubidium 
Standard it is another story and I hope someone will give you advise.
