CHU – 7850 kHz

At about 0831 UTC on Thursday, 31st July 2025, I tuned in to CHU time signal station, CANADA, transmitting on 7850 kHz.

CHU is the call sign of a shortwave time signal radio station operated by the Institute for National Measurement Standards of the National Research Council, in Ottawa, Ontario, Canada.  (Wikipedia 2023)

Three frequencies are used: 3330, 7850, and 14670 kHz.

The station commenced in 1923 with a callsign of 9CC and was used on an experimental basis until 1928.  In January 1929, regular daytime transmissions commenced under the callsign of VE9OB on 7353 kHz.  At the end of 1929, continuous transmissions commenced on the 90m band.  The station’s callsign was changed to CHU in 1938.  (Wikipedia 2023)

Below is a short video of my reception of CHU.
