I love DCF77. All my clocks in my home synchronize with it and are always spot on, without requiring a network connection. Never have to check whether they are still accurate and no hassle switching between summer/winter time!
I even used to have a wrist watch which was able to synchronize with it.
- Avamander 5y agoI tried to have the same, but I'm barely out of the signal's range unfortunately.
- zh3 5y agoTry moving the clock to face a different direction. Also the reception varies a lot throughout the day (bad near sunset and sunrise); most radio clocks rely on gettings the occasional good reception and running in the conventional way the rest of the time. So it can be a case of waiting a day or two for the clock to get a good time reception.
- Avamander 5y agoYep, that's what I've done and why I think I'm barely out of range. It's a bit tedious with wall clocks.
- liotier 5y agoSame here, the kitchen wall clock and all my alarm clocks use it. It just works, much more efficiently than NTP over a whole network stack, so an AA battery easily lasts a year.
