[time-nuts] FE5680 Frequency adjustment voltage range

[Bob Camp]

Hi

There is a lot of data on the small FE rubidiums out there. They appear to have re-packaged the same basic electronics into several different packages. You may want to dig into some of the other models to get a complete idea of what's going on with your unit. 

I would not worry a lot about the trim range until the unit has been on power for at least a month.
