NRC CHU Time

International frequency allocation changes are causing NRC to seek suggestions and/or support for the impending changes to CHU 7335 kHz transmissions, and maybe even CHU's future. If you are a user of those time signals, have a look at the website:

CHU Time
Service Time accuracy superior to telephone time accuracy is available throughout Canada and in many other parts of the world by means of NRC's radio time signals broadcast continuously from short wave radio station CHU. If corrections are made for the propagation delay from CHU to the user, and for delays in the user's receiver, an accuracy of better than 1 ms can be obtained. Signal availability at a user's location depends on ionospheric conditions. CHU also broadcasts a time code which can be decoded with common computers and modems.
