You won’t find an AM radio in a Tesla Model X. You also won’t find it in other electric cars, such as the BMW i3. One reason is that AM reception is trashed by electrical noise, which computing things constantly cause. Another is that the best AM reception requires a whip antenna outside the car: the longer the better. These days car makers hide antennas in windows and little shark fins on the roof. Another is that car makers have been cheaping out on the chips used in their AM radios for years, and the ones in home radios are even worse.
Demand for AM has been waning for decades anyway. AM doesn’t sound as good as FM or digital streams on laptops and mobile things. (Well, it can sound good with HD Radio, but that’s been a non-starter on both the transmitting and receiving sides for many years.) About the only formats left on AM that get ratings in the U.S. are sports and news, and sports is moving to FM too, even though coverage on FM in some markets, relatively speaking, sucks. (Compare WFAN/660am and 101.9fm, which simulcast.)
AM stations are back in the pack at best in the ratings. In Raleigh-Durham, WPTF/680 ruled the “the book” for decades, and is now the top of the bottom-feeders, with just a 1.0% share. KGO/810, which was #1 for a lifetime in the Bay Area, is now #19 with a 2.0% share. Much of KGO’s talent has been fired, and there’s a Facebook page for disgruntled fans. Not that it matters.
In Europe, AM is being clear-cut like a diseased forest. Norway ended AM broadcasting a while back. Germany killed all AM broadcasting at end of last year, just a few days ago. The American AFN (Armed Forces Network), which I used to love listening to over its 150,000-watt signal on 873Khz from Frankfurt, is also completely gone on AM in Germany. All transmitters are down. The legendary Marnach transmitter of Radio Luxembourg, “planet Earth’s biggest commercial radio station,” also shut down when 2016 arrived. Europe’s other AM band, LW or longwave, is also being abandoned. The advantage of longwave is coverage. Signals on longwave spread over enormous territories, and transmitters can run two million watts strong. But listening has gone steadily down, and longwave is even more vulnerable to electrical noise than MW. And running megawatt transmitters is expensive. So now Germany’s monster signal at 153KHz is gone, and France’s at 162KHz (one of 2 million watt ones) is due to go down later this year. All that’s keeping BBC’s landmark Radio 4 signal going on 198KHz is a collection of giant vacuum tubes that are no longer made. Brazil is moving from AM to FM as well. For an almost daily report on the demise of AM broadcasting around the world, read MediumWave News.
FM isn’t safe either. The UK appears to be slowly phasing out both AM and FM, while phasing in Digital Audio Broadasting. Norway is following suit, and killing off FM. No other countries have announced the same plans, but the demographics of radio listening are shifting from FM to online anyway, just as they shifted from AM to FM in past decades. Streaming stats are only going up and up. So is podcasting. (Here are Pew’s stats from a year ago.)
Sure, there’s still plenty of over-the-air listening. But ask any college kid if he or she listens to over-the-air radio. Most, in my experience anyway, say no, or very little. They might listen in a car, but their primary device for listening — and watching video, which is radio with pictures — is their phone or tablet. So the Internet today is doing to FM what FM has been doing to AM for decades. Only faster.
Oh, and then there’s the real estate issue. AM/MW and LW transmission requires a lot of land. As stations lose value, often the land under their transmitters is worth more. (We saw this last year with WMAL/630 in Washington, which I covered here.) FM and TV transmission requires height, which is why their transmitters crowd the tops of buildings and mountains. The FCC is now auctioning off TV frequencies, since nearly everybody is now watching TV on cable, satellite or computing devices. And at some point it becomes cheaper and easier for radio stations, groups and networks to operate servers than to pay electricity and rent for transmitters.
This doesn’t mean radio goes away. It just goes online, where it will stay. It’ll suck that you can’t get stations where there isn’t cellular or wi-fi coverage, but that matters less than this: there are many fewer limits to broadcasting and listening online, obsoleting the “station” metaphor, along with its need for channels and frequencies. Those are just URLs now.
On the Internet band, anybody can stream or podcast to the whole world. The only content limitations are those set by (or for) rights-holders to music and video content. If you’ve ever wondered why there’s very little music on podcasts (they’re almost all talk), it’s because “clearing rights” for popular — or any — recorded music for podcasting ranges from awful to impossible. Streaming is easier, but no bargain. To get a sense of how complex streaming is, copyright-wise, dig David Oxenford’s Broadcast Law Blog. If all you want to do is talk, however, feel free, because you are. (A rough rule: talk is cheap, music is expensive.)
The key thing is that radio will remain what it has been from the start: the most intimate broadcast medium ever created. And it might become even more intimate than ever, once it’s clear and easy to everyone that anyone can do it. So rock on.
