As Prime Minister Mark Carney’s Liberal government has been tightening its belt on the public purse (while simultaneously making huge promises that push the country’s budget back in the red), various federal departments have been looking at things they can cut to save money. The most obvious targets for such cuts are things that (a) cost a non-trivial amount of money, (b) use old technology and are hard to maintain, (c) have cheaper alternatives, (d) are not used by a public that isn’t even aware of its existence, and (e) don’t employ a large number of people.
So it probably shouldn’t be surprising that this year is seeing the end of two government-run radio services that you probably didn’t know existed.
Weatherradio
On March 31, Environment and Climate Change and other buzzwords Canada’s Weatherradio service shut down for good. The network of more than 200 transmitters across the country broadcast automatically-generated English and French audio weather reports on VHF frequencies (162.55 MHz in Montreal) that could be received by anyone with a receiver tuned to those frequencies (which, in practice, meant amateur radio operators and people who had AM/FM radios that offered a “weather” option).
Besides some radio and weather enthusiasts, there was little reaction to the decision to shut down the service.
The government argues that other, more widely adopted technologies make Weatherradio obsolete. Most communities within the reception areas of these stations can access the internet on their phones and use the WeatherCan mobile app to get their forecasts. Emergency weather information can be transmitted through wireless public alerting and through emergency alerts on AM and FM radio stations, that people are more likely to be listening to anyway. And sailors will still have access to the marine VHF channels run by the Coast Guard.
Opponents to the shutdown talk about how unreliable the cell network is, particularly in more remote communities, and particularly in a weather emergency that might, say, knock out power to cell towers. While it’s a good point, it’s hard to make a case that an automated system that few people have the technology to receive would be better than (or must be paired with) a system that uses AM and FM radio stations, cellphone towers, TV stations and TV providers to all simultaneously broadcast emergency messages when ordered by the government to do so.
CHU
The other radio service being shut down is Canada’s shortwave time signal station, which operates under the callsign CHU.
The station, which broadcasts from Ottawa on 3.33 MHz, 7.85 MHz and 14.67 MHz, gives you the current time, and emits a tone every minute on the minute so you can synchronize your clock to it.
CBC radio listeners may remember when the stations emitted a tone at 1pm so people could synchronize their clocks (until they stopped doing it in 2023 in part because many people listen to the radio in ways that make it inaccurate). This is a similar service.
Run by the National Research Council, the broadcasts were ultra-precise, boasting an accuracy of under a millisecond based on atomic clocks.
But most people don’t set their clocks by radio these days. Computers and other internet-connected devices use the Network Time Protocol, and NRC is keeping its NTP servers going. Mostly, the time signal is used to test shortwave radios, or as a curiosity for someone who hasn’t heard it before.
And, though “don’t rely on the U.S.” has been a slogan of late, people who want to listen to a time station will tend to tune in to the broadcasts from WWV (Colorado) and WWVH (Hawaii) on the sexier and easier to remember frequencies of 2.500, 5.000, 10.000, 15.000, 20.000 and 25.000 MHz.
The news of CHU’s shutdown, set for June 22, has generated even less buzz, with a few hobbyists lamenting its nearly 100-year-old history but not much else.
I’ve listened to both CHU and Weatherradio over the years, and I will miss them. But if that’s the price to pay to finally get high-speed rail between Montreal and Toronto (it will, of course, actually cost way more than the price of these services), then I’ve reached the stage of acceptance that this era of automated radio is behind us.
Goodbye, soulless number-reading machines.
