Senator Urges Automakers to Keep Making Cars with AM Radio (boston.com) 320

The Boston Globe reports that U.S. Senator Ed. Markey just sent a letter to more than 20 car manufacturers asking them to continue including AM radios in future car models — including electric vehicles: Some EV manufacturers have raised concerns even as far back as 2016 about how the battery power of an EV can interfere with AM radio signals. However, Markey addressed these concerns saying, "car manufacturers appear to have developed innovative solutions to this problem."
"The last time I listened to AM radio was in the late 1970s," writes long-time Slashdot reader non-e-moose. "And then it was mostly because there were either no FM stations in reception range, or I was riding my bicycle and only had a transistor radio."

But the Senator sees it differently: AM radio has long been an important source of information for consumers. Before the COVID-19 pandemic, nearly 90 percent of Americans ages 12 and older — totaling hundreds of millions of people — listened to AM or FM radio each week, higher than the percentage that watch television (56 percent) or own a computer (77 percent).... Moreover, 33 percent of new car buyers say that AM radio is a very important feature in a vehicle — higher than dedicated Wi-Fi (31 percent), SiriusXM satellite radio (27 percent), and personal assistants such as Google Assistant (12 percent) and Amazon Alexa (9 percent). In other words, broadcast AM and FM radio remain an essential vehicle feature for consumers.

Moreover, broadcast AM radio, in particular, is a critical mechanism for government authorities to communicate with the public during natural disasters, extreme weather events, and other emergencies. AM radio operates at lower frequencies and has longer wavelengths than FM radio, so AM radio waves more easily pass through solid objects. As a result, AM radio signals can travel long distances, making them well-suited for broadcasting emergency alerts....

Despite innovations such as the smartphone and social media, AM/FM broadcast radio remains the most dependable, cost-free, and accessible communication mechanism for public officials to communicate with the public during times of emergency. As a result, any phase-out of broadcast AM radio could pose a significant communication problem during emergencies.... Given AM radio's importance for emergency communications and continued consumer demand, I urge your company to maintain the feature in its new vehicles...

    The tuner chip is probably 50 cents and does both anyway.

    Personally, I'd be down with making the DIN slot great again. Provide a standard sized slot for the audio equipment, provide a standard interface to the steering wheel/voice/screen controls, allow the customer to be able to add what they need at will.

    The trend of integrated everything, run by the same screen or (worse), crappy-ass capacitative controls that are useless in cold weather, needs to die gurgling. That's one of the reasons why I prefer the Bolt EV (not EwwwV) over offerings from Tesla or VW -- it still has an interior without the ergonomic sins of those cars. Make a normal car that's electric; stop trying so hard to be fashionable or modern for the sake of modernity.

    • Modular is best indeed.

      My husband's 2017 Bolt EV features an external audio input, also. Just 1/8". No DIN. But it allowed for the installation of an aftermarket CD player. The car of course supports AM and FM from the factory.
      There are a lot of bugs in the infotainment unit, though.

        The problem with that is money -- as it the automakers' money. They can't rip you off in five years selling you an entirely new car with an entirely new infotainment system (or OTA updates) if you have an option to "opt out."
        • GM isn't doing OTA updates on the Bolt. There are dealer software updates, but they are only for major stuff like recalls. I haven't seen any infotainment bugs fixed. The most annoying bug has to do with radio presets, actually. Sometimes you get duped presets, and you can't switch preset with the physical paddle, only with the touch screen. Only seems to happen with classical KDFC on FM. Other stations work fine.

          That doesn't seem to be the case, given that most of them support Android Auto and Apple Carplay.

          Those two are the new DIM slot. People just want a screen that their phone can display on, and use their existing cellular plan with instead of paying a subscription to the car manufacturer.

          I'm sure they will be happy to sell you over-priced updates, but once you have Android Auto/Carplay there really isn't much incentive to spend any money updating the built in system.

      Most of the vendors that used to make AM receiver chips have stopped and only sell FM receiver chips now - so it's a good thing no chips are required to make a good AM receiver.

      There's actually a dirty little secret here: The FCC has, as a basic justification for its existence, the duty to protect the AM, FM, and TV transmission bands from interference, and this is actually what killed some computer lines like the Radio Shack TRS-80 series. Back in the late '70s to early '80s the FCC upped its enforcement and regulations and both the Apple II and the TRS-80 interfered too much. To see what Atari did to pass the tests, get a look at all the metal under the hood of an old Atari 400 - prepare to be stunned if you've never seen it. Apple went to the Apple IIe (with RF coating added to the inside of the case) to get into compliance, but Radio Shack did not get their systems into compliance (probably lacked funding to do the engineering). Remember, THOSE computers were only running at a couple of MHz (NOBODY then was even imagining a microprocessor at gigahertz speeds). The modern PC is a far worse offender, but the huge PC makers came up with a work-around for the regulations (NOT an actual honest solution) - they have the clock circuits on modern very fast CPUs jitter about the desired frequency, thus scattering the noise enough to get through the specific FCC tests, but this scheme does indeed leave the PC cluttering-up the AM radio bands. There's also loopholes in the regs for digital noise emitted by circuits aboard vehicles (which cars ARE, of course). As a result, it can be hard to get a good AM signal near a modern PC or near the computers in cars (which makes it hard to make a good AM radio receiver in a modern car). Car makers would love to eliminate these receivers, in part because it saves a tiny bit of cash in a low-profit margin business, but also because it's difficult to make and integrate a good one that will not produce consumer complaints. Oh, and the FCC has essentially ignored the PC clock jitter scam because an entire industry which is vital to the nation has no practical work-around and is TECHNICALLY in compliance even though it is in violation, in spirit.

        You're about half right.

        It is often stated that Radio Shack was forced by the FCC to recall the Model I. That is incorrect and based on a misunderstanding of the FCC rules. The new FCC regulations applied only to hardware manufactured after January 1, 1981. Any non-certified product manufactured before that date could still be sold until July 1, 1982 as long as it displayed [a disclaimer] label:

It has very broad coverage (especially at night) and receivers are already present in most all cars on the road. Our society has become so accustomed to the Internet working everywhere that we've forgotten about the simpler, more robust ways of getting messages out.

          It would actually be a good thing if a few mega-outages like that would happen sooner rather than later. A lot of our infrastructure is being kept alive with bandaids and small fixes. I get it, it's the cheaper way. But a lot of severe weather is coming down the tubes and half our population has been programmed to disbelieve any possible change to our weather. The sooner that the red states see a few serious catastrophes, the sooner they'll start adapting. Not that the blue states are much better. They talk more reasonably about the issue but California's power grid is a mess and nobody wants to make the hard decisions.

          But it can't be some little hurricane that causes a weeks outages and a few billion dollars of damage. That'll be forgotten 24 hours after the power is restored. We need major infrastructure going down- affecting entire states - for like a month or more. That's the only thing that'll get people's attention.

    This isn't about hearing talk radio or some sort of nostalgia kick. This is about emergency communication.

    AM is simple (that's why we had it first). It's simple to transmit and simple to receive. Though few remember, a graphite pencil, a safety pin, a razor blade, and an old piezo earphone will work if that's all you can get.

    Basic spark gap transmitters present few requirements if you don't care about staying on your assigned frequency or in any sort of fidelity (or just do CW). In an emergency, that's fine.

    It's also easy to transmit for a long distance (for example, from outside of the disaster stricken area).

That's why there are traffic signs that say "Tune to AM 1250 for traffic info"...

    It might seem like an irrelevant technology, but rural communities and in particular Native communities depend on radio, especially for emergency management. The non-profit, Native Public Media, states: Native radio and television stations play a vital role in promoting the safety, sovereignty, and stability of Native communities. These broadcast facilities provide vital information upon which Tribal citizens can make informed decisions. Stations share this information through storytelling, hyperlocal news, civic engagement, and emergency communications for predominately rural and remote tribal lands. Fifty-eight Tribal radio stations, and three television stations, benefit from NPM programs in regulatory compliance, governance, technical assistance, training, policymaking, and operations development. https://www.nativepublicmedia....

      The ionospheric propagation of the MW band is more of a drawback than an asset though, as it ensures you can never entirely get rid of interference merely by being far away from a station. The main benefit of AM is that the receivers can be dead simple (though they often aren't, now). FM requires a bit more skill to demodulate, and SSB needs very tight tuning to be tolerable. Neither one is terribly difficult now, but if there was something like another Carrington Event, it would be a lot easier to hack tog

    I was involved with development of an infotainment for use in the Air Stream RV about 6 years ago. During the product specification phase there was debate over the inclusion of AM. While the cost is not high it is not zero and there is technical risks around noise, such as that from switch mode PSUs inside the system.

    In our discussion the common view was almost no one uses AM anymore. That was certainly the case here in New Zealand where the project was undertaken. However the counter argument was in the USA that AM was still used for the broadcast of local sports, such as what they call football there. As result it was seen as product requirement and was included. Suitable consideration and testing was taken to ensure it worked with reasonable performance. The extra cost per unit was near nothing but it did add to the product development time.
    • by Mal-2 ( 675116 )

      If you're marketing primarily in North America, including AM is a good idea. An RV in particular is likely to end up in an area where there's no FM reception, but they can still get AM. However, if you make the head unit replaceable, it's not really that big of a deal if it doesn't do everything for everyone. People change the stereos in their cars all the time, I don't see why an RV would be any different.

        The replaceability side is driven by the vehicle manufacture, in Air Stream's case Mercedes. To Mercedes' credit they did allow different stereos but the reversing signal for backing cameras was only on a CAN bus, not a physical line, so general after market units would usually be feature limited. Also the plastics need custom made to suit the existing plastics if you wanted it to look reasonable. Basically just a hassle.

    Predictably, plenty of voices here saying that AM is an obsolete cesspool of (mostly right wing) politics. They're leaving out that it also has local traffic, news, and will break in for anything truly earth-shattering like a disaster. The reach of AM signals is also farther than FM, even though the quality might not be as high. Receivers are so dirt simple, every kid who's interested in electronics builds one with a few simple parts--a "crystal set" doesn't even require power to pull in some stations. Transmitters are not that much more complicated.

    At any rate, I defy anybody to tell me that the SNR for AM radio content isn't generally better than the Internet. If anything, the Internet fed the trolls on AM radio, not the other way around. You might just live in a sucky market, too.

    There are plenty of towns with established AM stations pumping out vital information, as well as the occasional local sports play-by-play. Don't be so quick to throw it all away.

    If nothing else, its simplicity makes it immune from the kind of walled garden locked-downs or suckscription models you get with other media. We're supposed to fight that, aren't we? AM is AMmunition against such control.

    Emergency preparedness at least in the USA relies too much on vulnerable "high tech". And I don't mean the cell phone alert system - I mean that emergency services for "real" disasters rely too heavily on satellite communications. That "silly" scene in "Independence Day", when the Americans Morse code other nations that they are planning a counter offensive is not all that silly. If you think about it, it takes a few more brain cells to operate a radio (voice – I am not necessarily advocate using Morse code) than operating a satellite phone, but even if all infrastructure is gone, you can establish radio links, even if it means hand cranking a little generator. So, from that point of view, keeping radio communication capabilities wide-spread may seem quaint, but it is also smart. For disclosure, I usually listen to FM - better sound quality. And no data plan required ;-) But I also own some shortwave receivers, so call me biased.

    Just my 2 cents.
