The GC-1000 was the Most Accurate Clock. This new GC-1006 is Most Reliable without mentioning accuracy.
The ad says that the standby oscillator can be calibrated by pushing some buttons on the back. Wondering how they do that almost makes me want to buy a simple clock that is $100 per pound. Perhaps there is a motor that turns a tuning capacitor to make the standby oscillator match the line frequency. More likely software changes the number of counts of some inexpensive XO per cycle. I have an alarm clock with 2" seven segment LEDS that I can read without glasses. Its backup oscillator is LC, and somewhat faster than the line. It has carried me through the short outages I've experienced. There's not enough info on what's behind the Santa Cruz rebirth of Heathkit. If I thought they were solid, I'd buy a kit to help prime the pump, so to speak. As it is, I'll be looking for neon-colored seven segment arrays a bit taller than those in the GC-1006. No doubt, there are many schemes for disciplining 60 (or 50) Hz oscillators with 1 PPS. TIA for any helpful comments.
