CHU is a time signal radio station operated by the Institute for National Measurement Standards of the National Research Council of Canada.
The signal is broadcast on three frequencies:
- 3330 kHz (3Kw)
- 7850 kHz (10kW)
- 14670 kHz (3 kW)
The station was started in 1923 by the Dominion Observatory in Ottawa, Ontario, Canada, with a call sign of 9CC on an experimental basis until 1928. In 1938, the call was changed to CHU.
Below is a short video of my recent reception of CHU on 14670 kHz. and an earlier video from 2022 of my reception of CHU on 7850 kHz.
