CHU – Shortwave Time for Canada 7.850MHz

This is the first time I have seen this sort of format – a station transmitting in a four segment transmission.  A carrier, a voice segment slightly higher, a tone segment slightly higher than that, then a data segment beyond that.

They transmit the time in English and French, with a tick beep for seconds, and every minute they send a digital encoded time.

I will have to see if there is a decoder for this or other time stations to synchronize clocks as a project.

This station was fairly easy to find information on, https://en.wikipedia.org/wiki/CHU_%28radio_station%29
