Re: MSF or DCF clock module instead of GPS


What I would really like to see is an RTC interface so my U3s don’t loose the clock setting when switched off. I have several units and it is right pain having to manually set all the clocks to the nearest second every time I power them on. As Alan says, you can calibrate out the errors in the uP xtal, so is the 1PPS really needed?
