## Description

I have a Casio G-Series radio watch, but it is always unable to receive radio waves from time signal station, so I started to write an application to solve this problem.  
  
After some research, I finally wrote this application, which can perfectly simulate the timing signal and happily calibrate the time.  
  
Usage method:  
1\. Adjust the volume of phone to the maximum.  
2\. Switch the radio controlled watch / clock to manual wave receiving mode.  
3\. Click the "start" button.  
4\. Place the watch / clock near the phone speakers.  
5\. The synchronization process generally takes 3-10 minutes, please wait patiently.  
  
Matters needing attention:  
1\. Please try to use the software in a quiet environment to avoid signal interference.  
2\. The volume of the mobile phone must be adjusted to the maximum. It's too small and the effect is not good.  
  
Characteristic:  
1\. Supports simulation of all types of Time Wave Signal:  
\* China BPC  
\* USA WWVB  
\* Japan JJY40 / JJY60  
\* Germany DCF77  
\* British MSF  
2\. The unique "Beast Mode" provides higher frequency simulation signals and faster sync.
