Personally, I do not understand what the benefit is of using the mains frequency. I always use a 4.194304MHz Quarz and so far all my clocks' accuracies are very satisfactory.
The benefit WAS that the Hydro Utilities always averaged out the frequency to avoid long turn drift, so that the clock would stay on time for months. It is hard (but not impossible) to get a crystal source that will stay to the same level of accuracy.
Now of course the "way forward" is to use GPS or WWVL methods, or even NTP. -- Charles MacDonald Stittsville Ontario [email protected] Just Beyond the Fringe http://www.TelecomOttawa.net/~cmacd/ No Microsoft Products were used in sending this e-mail. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
