American vs. Canadian Radio Stations

“American vs. Canadian Radio” — drawn by bing.com/images/create

A couple of years ago I was asked on Quora, “How do American radio stations compare to Canadian stations?” This was my answer


Mostly the differences are regulatory. But some are also geographic. Examples:

  1. The Canadian government has a national network, the CBC, much as does the U.K. with the BBC. And, like the BBC, it’s very reputable. Both are “royal” entities, for which there is no U.S. equivalent. (And no, NPR doesn’t qualify, since it’s independent of the federal government and almost entirely—last report, 98+%—paid for by member stations, sponsorships and underwriting.)
  2. Programming is more highly regulated, especially around music, in Canada. For example, the Canadian Radio-Televsion and Communmicatons Commission (CRTC) has Canadian content requirements for music on Canadian radio, which requires that commercial, community, campus and native radio stations “must ensure that at least 35% of the Popular Music they broadcast each week is Canadian content.” The percentage for CBC stations is 50%.
  3. The CRTC is committed to sunsetting AM broadcasting, while the FCC is not. While there are still some CBC stations still on the AM band, many signals have either gone dark or have been sold off. Here is a list of the remaining CBC AM signals.

Despite Canada’s slow rollback of AM broadcasting, its prairie features an AM station with the largest daytime* coverage in the world: CBK/540 in Watrous, Saskatchewan. While there are lots of 50,000-watt stations in the world (and that’s the max allowed in the U.S. and Canada)—and a handful cranking out up to two million watts—CBK’s 50,000-watt transmitter sits on some of the most conductive dirt in the world, giving the station coverage that reaches from the Rockies in Alberta to the west, the shores of Hudson Bay to the east; and north across the borders of the Northwest Territories and Nunavut, and well into Montana, North Dakota, and Minnesota to the south:

One of those two million-watt giants is Transmitter Solt, for Kossuth Rádió, Hungary’s national radio station. While its signal is immense electronically, its daytime* coverage, while very large, is limited by relatively nonconductive ground. Still, in a way, Transmitter Solt is also Canadian, since the transmitter itself is made by Nautel, of Nova Scotia, which in recent years has become what some regard as the preeminent maker of broadcast transmitters.

*Note that coverage by day and night is vastly different for AM (aka MW) radio. That’s because in daytime the lowest (D) layer of the ionosphere absorbs signals in that band, and at night the same signals bounce off the next layer up (E) for distances typically of several hundred miles. Or, in cases like Transmitter Solt, thousands of miles. As a somewhat separate matter, shortwave signals bounce off the higher F1 and F2 layers. Check that last link for particulars.

On Infrastructure’s Absence

January 2nd, 2024 · No Comments

Joshua trees shot in pano mode by a phone in a moving car.

I’m making lemonade here. The lemon is erroneously putting an album of photos shot at Joshua Tree National Park into my Flickr site devoted to infrastructure rather than the one for everything else. The lemonade is giving this blog some juice in the form of a useful topic: absence of infrastructure. There is a lot of that in the world, and this park is an okay example.

I say okay because it’s not Antarctica, the middle of the ocean, or the Taklamakan. There is a paved road, on which tantalized visitors can gaze through car windows before they hike off on foot to look at wildlife, climb rocks, and enjoy other adventures. There is also some cell coverage, even though the park says there is none. We could get online most of the way to the Wall Street Stamp Mill ruins. Two days earlier we took a hike to Barker Dam, which also featured a bit of cell coverage.

Just off the trail nearby are the remains of a windpump style windmill, that supplied water for the mill and the ranches nearby. Not sure what anyone ranched there, but the windpump made a degree of civilization possible. And I suppose that’s what infrastructure is: a minimum requirement for the kind of life we call civilized.

Thoughts welcome.
