America's Car Industry Seeks to Crush AM Radio. Will Congress Rescue It? (msn.com) 262

The Wall Street Journal reports that "a motley crew of AM radio advocates," including conservative talk show hosts and federal emergency officials, are lobbying Congress to stop carmakers from dropping AM radio from new vehicles: Lawmakers say most car companies are noncommittal about the future of AM tuners in vehicles, so they want to require them by law to keep making cars with free AM radio. Supporters argue it is a critical piece of the emergency communication network, while the automakers say Americans have plenty of other ways, including their phones, to receive alerts and information. The legislation has united lawmakers who ordinarily want nothing to do with one another. Sens. Ted Cruz (R., Texas) and Ed Markey (D., Mass.) are leading the Senate effort, and on the House side, Speaker Mike Johnson — himself a former conservative talk radio host in Louisiana — and progressive "squad" member Rep. Rashida Tlaib of Michigan are among about 200 co-sponsors...

A spring 2023 Nielsen survey, the most recent one available, showed that AM radio reaches about 78 million Americans every month. That is down from nearly 107 million in the spring of 2016, one of the earliest periods for which Nielsen has data... Automakers say the rise of electric vehicles is driving the shift away from AM, because onboard electronics create interference with AM radio signals — a phenomenon that "makes the already fuzzy analog AM radio frequency basically unlistenable," according to the Alliance for Automotive Innovation, a car-industry trade group. Shielding cables and components to reduce interference would cost carmakers $3.8 billion over seven years, the group estimates.

Markey and other lawmakers say they want to preserve AM radio because of its role in emergency communications. The Federal Emergency Management Agency says that more than 75 radio stations, most of which operate on the AM band and cover at least 90% of the U.S. population, are equipped with backup communications equipment and generators that allow them to continue broadcasting information to the public during and after an emergency. Seven former FEMA administrators urged Congress in a letter last year to seek assurances from automakers that they would keep broadcast radio available. The companies' noncommittal response spurred legislation, lawmakers said.

Automakers increasingly want to put radio and other car features "behind a paywall," Markey said in an interview. "They see this as another profit center for them when the American driving public has seen it as a safety resource for them and their families...." He compared the auto industry's resistance to the bill to previous opposition to government mandates like seat belts and air bags. "Leaving safety decisions to the auto industry is very dangerous," Markey said.

Lawmakers have heard from over 400,000 AM radio supporters, according to the president of the National Association of Broadcasters.

But the article also cites an executive at the Consumer Technology Association, who says automakers and tech advocacy groups have told lawmakers that requiring AM radio "would be "inconsistent with the principles of a free market.... It's strange that Congress is focused on a 100-year-old technology."

        Yes, those are all the business reasons not to have an AM radio. Everyone is aware of that. That's why car companies are openly talking about not having AM radios.

        The potential regulation is to force companies to do something that's not strictly for profit but for the public good.

    AM carries better though it also tends to get more interference. It's dead simple for someone with electronics knowledge to make an AM radio with materials and tools that are probably far more basic than you'd expect.

    If you want to put out an unencrypted signal in the worst conditions and expect the most people to get it, AM would be the way I would suggest to do it. For that reason, I think it'd be nice if AM was kept around as an emergency backup if nothing else.

    • For emergency backup you're welcome to throw a $20 battery + crank AM radio in your glovebox. Not sure why people insist that the automaker has to build it in to the car itself if it's really just meant for emergency purposes.

      HD Radio on most AM stations happened well over a decade earlier than 2020. What eventually happened is that the stations now turn off HD Radio after dark because the "AM skip" effect corrupts the digital signal making it unlistenable.

      To add insult to injury, most AM broadcasters also turn off their HD Radio signal when broadcasting live sports because of the minimum 20-second delay inherent to HD Radio. It turns out people still listen to baseball games on the radio when in the stadium.

    The money behind this doesn't give the slightest crap about emergencies. They're just using that as their lever. They care about all the money they've sunk into AM. The people arguing for this are right wing talk radio. (Clear Channel, Salem, etc.)

    And it's frustrating because the straw man they are using is actually RIGHT. I really hate to agree with them, especially when I know they're not acting in good faith.

    BUT we could solve everyone's issue here (from an emergency standpoint) but just making a reliable emergency carrier, on a few chosen AM frequencies. The car companies wouldn't have to get all AM frequencies working, or even support analog signals. The emergency carrier could send out analog on one frequency in the AM area, and digital on others. You could use old AM radios to get the analog one (or two or three with a good spread for a little more reliability/avoiding interference) or buy a new radio for the same info (plus maybe pictures, downloads, etc) on a slow digital signal, also in the AM spectrum.

    The car companies would only support the digital, which is fine, since it means they don't need to keep AM un-noisy. People could still use old AM radios, and companies could make money selling trivial digital radios for clear (lo-fi) AM data. The same emergency data could also go out on FM, as that will work most of the time, anyhow. Everyone wins. ... except right wing talk radio. Screw them.

In the past, it took almost no effort to get AM radio working in car. Newer vehicles have more electronics that interfere with the AM signal.

    In places on the eastern seaboard, the highways are already signed with the AM frequency to tune to, for both traffic (i.e. on tunnel bottlenecks) and also specifically for emergency information about hurricanes and floods (and how the lanes will be used during those events). Those are local area dedicated transmitters. Not to mention that the government (since the 40s or 50s) already has a commercial AM-radio based national emergency broadcast system. (They can access smartphones, too, but what is still working when the cell towers and stuff are down? AM radio, that's what.)

    If the public is as technically illiterate about this as is evidenced here on /., maybe the system needs more clueless-user automation. Maybe the legislation ought to mandate AM radio receivers in all cars that automatically alert the driver when an emergency recognition tone is detected on any AM band. Make it a required safety item in the USA, no need for the user to know anything more than "push the AM button that is flashing, if you aren't already getting better information on the screen in your car or phone". No need to manually tune. Although if you think it's entertaining, you can also dial/scan around and listen whenever you want.

    Where I live, FM radio is almost worthless during a natural disaster. I'm in hilly terrain, so the stations I can receive are limited, and the selection of stations with intelligible reception may change every few miles. Virtually all of those stations are part of nationally-owned radio networks, which means they're playing content from a central, national studio. There's nobody in the local station; if there's a "local DJ," chances are they prerecorded their schtick for the week on Monday.

    In a regional emergency, the best one can hope for from the FM stations is that they'll start playing the audio feed from an affiliated local TV station. This isn't very useful, because the TV people are working for their TV audience, who can see what they're talking about. They don't always describe what they're broadcasting. In an emergency, you need clear communication of information, and "let's just use the local TV station's audio feed" doesn't provide this.

    While AM radio is increasingly centralized as well, for whatever reason the AM talk stations are more likely to have at least one live body near a microphone in the office, and some vestige of a news organization. That means AM radio is more likely to break into the national programming with local information. I can't recall the last time that happened on FM radio around here.

    If the US wants to get rid of AM radio in cars, we need to address how radio consolidation has all but eliminated useful, timely local news on FM radio first.
