This radio timing module model is WVB-0860N-03A, which is suitable for US radio clock adjustment, not for other countries.
It is mainly used for radio clocks that require high-precision time synchronization, such as clock systems in homes, offices, schools, hospitals and other places.
The receiving module operates at 60KHz, which is one of the commonly used broadcast frequencies for US radio clocks.
It is specially designed to be compatible with US radio clock systems and can accurately receive and decode broadcast signals to adjust clock accuracy and time synchronization.
As a single-frequency module, it can only receive 60KHz signals in this frequency band.
