●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.

●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
You can select 44.1kHz or 48kHz.

●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)
*Emits a high frequency sound similar to so-called mosquito noise. Please be aware that the loud volume is simply not audible.
