Use in places where JJY standard radio waves cannot reach or are difficult to receive when setting the time on a radio clock.
You can set the time even in the basement of a building or overseas!

●Description
This app is an app that pseudo-simulates Japan Standard Radio JJY.
By connecting your smartphone's speaker or earphones, it will send a simulated radio wave to set the time of your radio clock.

Turn your smartphone to maximum volume and place the smartphone speaker next to the radio clock, or attach earphones and wrap the cord around the radio clock.
Then, when you set the radio clock to receive mode, it will synchronize in about 2 to 30 minutes.
*The time at which the time is synchronized depends on your environment.

●Equipped with time difference correction function
If the time is set incorrectly even when using radio waves due to the specifications of the radio clock, you can use this function to adjust the time.
The correction value can be set between -24 hours, 59 minutes, and 59 seconds to +24 hours, 59 minutes, and 59 seconds.
It can also be used to set summer time.

●Supported transmitting stations
40kHz (Fukushima Prefecture, Tamura City, Miyakoji Town)
60kHz (Fuji-cho, Saga City, Saga Prefecture)

●Harmonic order
2nd harmonic and 3rd harmonic can be selected.

●Output sampling rate

●Notes
*There may be cases where the time cannot be set due to combinations of smartphone models and radio-controlled clock models. note that. (This is not an app bug)
