Summary of this article: Canada’s time standard station on shortwave apparently is being shut down within the month, according to a brief notice on the Canadian government’s website. We detail the history of the station and tell you how to get a QSL card hopefully before it’s too late.

It’s hard to believe another shortwave station appears to be going silent. An official notice buried on a Canadian government website casts the obituary for CHU.

As a new shortwave listener in the early 1970s, this is the second QSL card received in the mail, shortly after a similar first QSL for U.S. time station WWV. The prized CHU QSL card verified a 1972 logging on 7.335 MHz on the author’s $40 Ross multiband receiver. | Photo from National Communications Magazine archives

The wording is short and to the point. The station that has been on the air since the previous millennium carrying official time signals across North America and the world is shutting down. Read below as we detail the closure, tell you how to get a QSL card before they go off the air and learn a little about the history of this station we all have tuned in.
