BPM (time service)
From Wikipedia, the free encyclopedia
BPM is the People's Republic of China's national time signal service, operated by the Chinese Academy of Sciences.
It broadcasts at 2.5, 5, 10, and 15 MHz.
BPM is idiosyncratic in that it transmits UT1 time between minutes 25 through to 29 and 55 through to 59, which creates an odd click-beep effect when heard below a stronger time signal station such as WWV.
