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. Contact information: Please contact me if you have any use questions *QQ: 3364918353 *Email: [email protected]
