End of CHU time station.

As of June 22, 2026, the shortwave broadcast of the official time signal of the NCRC will no longer be available.

Three frequencies were used: 3,330 (3 kW), 7,850 (10 kW modified from 7,335 since 2009-01-01) and 14,670 kHz (3 kW).

These frequencies came from one of the three atomic clocks in the emitting station.

Each frequency used its own antenna. All the electronic systems of the transmitter were doubled for greater security and were powered by a protected source by an accumulator and a generator. The generator could also power transmitters.

The transmission mode, single-side-band upper with re-inputed carrier, provided an hourly signal without the need to use a single-side band radio and also offered three standard frequencies.

Station identification is very easy: the announcements were made by a talking clock using digitally recorded voice.

The voice in French was that of Simon Durivage (from Radio-Canada) and the voice in English is that of Harry Mannis (former CBC host).

CHU Station is located 15km SW of Ottawa at 45° 17'47"N and 75° 45'22"W. It was the property of the National Research Council of Canada (CNRC).
