txtempus

As I wrote: it does work great where it does work. I'd definitely have gone that route if it worked where I live. It's just that the marketing that it works "all around the world" falls pretty short, IMO. I kinda wish the German transmitter had more range (like the US one does) but even the blog I linked to, you can see someone in the continental US who needs to hang their watch from their window blinds for syncing to work reliably. I even looked into hacking my own transmitter (https://github.com/hzeller/txtempus) before giving up and just buying one of the models with bluetooth phone sync.

We’ve come full circle. https://news.ycombinator.com/item?id=46952384 https://github.com/tanvach/clocksync https://github.com/kangtastic/timestation https://github.com/hzeller/txtempus WVB: A Tiny WWVB Station - https://news.ycombinator.com/item?id=13258631 - December 2016 (49 comments) https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...

You can use one of these to act as a local personal WWVB station amongst other things. See https://github.com/hzeller/txtempus and https://github.com/GOTO-GOSUB/Txtempus-Passive-Antenna

That's a cool clock. Do they make one that is radio controlled by US transmitters? If not, maybe txtempus[1] and a Raspberry Pi Zero W can help. Or pico_dcf77_tx[2] and a Pico W. 1: https://github.com/hzeller/txtempus 2: https://github.com/elehobica/pico_dcf77_tx

Related thread with local transmitters of time signal: https://news.ycombinator.com/item?id=27769403 https://github.com/hzeller/txtempus (A DCF77, WWVB, JJY and MSF clock LF-band signal transmitter using the Raspberry Pi) ios and mac app: https://forum.audiob.us/discussion/49109/pips-a-radio-time-s... (time sync over rf is super cool; I would be super interested if anyone has links to field surveys of time signal availability, potential gaps in coverage, and maps of said data.

Something that might be of interest: https://github.com/hzeller/txtempus I live in an area without decent WWVB reception. So one of these days, my plan is to build a house range WWVB antenna so that I can get all the radio clocks in my house working consistently.

https://github.com/hzeller/txtempus I made one for my Citizen RF synced watch. It works.

Ntp synced emulator for rpi which I use in Australia to sync my citizen skymaster I didn't write this code. It has about 10-20cm of useful propagation distance (this is a transmitter and may breach local RF regulations) We're outside the footprint of jjy, wwvb or dcf https://github.com/hzeller/txtempus

And if you live outside reception distance of JJY or WWVB or DCF77 there's a raspberry pi local transmitter model and it runs off ntp. Using it to sync my citizen watch in Australia. https://github.com/hzeller/txtempus
