DCF77 Emulator

A radio wave for electric wave clocks (DCF77) is offered.

Attention: There are a lot of people this application requests, so it's made. But there is no environment that a maker tests. Operation guaranteed won't be done.

Note

It can not correspond to the atomic clock. Please adjust the NPC time with other apps.

Correspondence in this application is not planned.

We will receive more emails requesting radio clocks from other countries, but since you can not create it without materials, please attach the clear material you need.

How to use

Place headphone speakers by the atomic radio clock's internal antenna, with the volume as high as possible before it starts to distort. Or, place the clock’s internal radio antenna as close as possible to the smartphone speaker. Again, with the volume as high as possible before it starts to distort. When time sync receive mode is active, the clock will sync within 2 to 3 minutes.
