AM Radio Has an Emergency Argument. The Industry Keeps Ignoring It.
The fight to keep AM in cars isn't just nostalgia -- it's about what happens when everything else fails.
When the AM For Every Vehicle Act started making the rounds in Congress a couple of years ago, a lot of people in the broadcast industry treated it like a lifeline. Here was a piece of legislation that would require AM radio receivers in new cars -- including electric vehicles -- and the industry rallied behind it like it was going to reverse twenty years of decline.
The bill had bipartisan support. It had backing from the National Association of Broadcasters. It had testimonials about emergency broadcasts reaching people when cell towers failed. It was, by the standards of federal media legislation, a genuinely serious effort.
It also mostly stalled out. And the reasons it stalled tell you something useful about the gap between what AM radio could be and what the industry has actually made it.
The core argument for AM in vehicles has always been emergency infrastructure. AM signals travel farther than FM, penetrate buildings better in some conditions, and don’t depend on internet connectivity or cell network uptime. When a hurricane comes through and knocks out towers, a 50,000 watt AM station can still reach people across a wide geographic area with information that keeps them alive. That’s not a metaphor. There are documented cases of AM being the last working communication channel during major disasters.
The EAS -- Emergency Alert System -- runs on AM and FM, but AM’s range advantage is real in large-scale regional emergencies. FEMA’s IPAWS system and the Integrated Public Alert and Warning System both lean on terrestrial broadcast as a redundancy layer precisely because it doesn’t require the infrastructure that digital systems need to function.
So the infrastructure argument is legitimate. It’s not manufactured nostalgia. It’s an acknowledgment that broadcast radio, and AM specifically, fills a gap that no streaming service or smartphone app fills reliably when things go wrong.
Here’s the problem. The industry made the argument with one hand while undermining it with the other.
The same corporate groups lobbying for AM receiver mandates in cars were simultaneously petitioning the FCC to go dark on AM stations. iHeartMedia. Audacy. Cumulus. All of them have filed or supported silent station requests on AM properties over the last several years. The logic is straightforward from a balance sheet perspective -- an AM station that generates no meaningful revenue is a liability, and the license can sometimes be sold or repurposed. But you can’t simultaneously argue that AM is critical emergency infrastructure and quietly drain it of the local stations that make that infrastructure functional.
A mandate that cars contain AM receivers is worth very little if the stations those receivers pick up are running automation from a server room in another state. Emergency value comes from local, live, staffed broadcasting. It comes from someone in the market who knows the roads, knows the shelters, knows which bridges are closed. Voice-tracked content piped in from a hub facility 800 miles away doesn’t serve that function. It serves the appearance of local radio without the substance.
This is the tension that the AM For Every Vehicle Act never fully resolved. The bill protected the receiver. It said nothing about what the receiver would actually pick up.
Congress got close enough to the issue to understand the infrastructure argument but not close enough to see how thoroughly the industry had already compromised the thing they were trying to protect. The mandate would have required the hardware. It couldn’t require the staffing.
KNX is a useful case study here because it’s one of the stations that actually makes the infrastructure argument hold up. A 50,000 watt all-news station in Los Angeles, staffed around the clock, covering local emergencies in real time -- that’s the version of AM radio the legislation was written to protect. The signal covers the entire metro and beyond. When something happens in Southern California, KNX is genuinely useful in a way that a lot of AM stations no longer are.
The irony is that KNX’s decision to go AM-only happened at the same time the AM infrastructure conversation was getting real traction in Washington. Whether Audacy thought about that framing or not, a major market all-news operation recommitting to AM sends a signal -- intended or not -- that the band still has serious operators on it.
The stronger version of the AM preservation argument isn’t “require the hardware.” It’s “require the function.” If you want to claim emergency infrastructure value, operate like emergency infrastructure. Live local programming. Staffed during severe weather. Actual knowledge of the market you’re serving. That’s what makes an AM station worth protecting, and it’s also what most corporate groups stopped doing on AM years ago.
The mandate without the function is just a receiver sitting in a dashboard tuned to a station that’s playing the same satellite-fed content it played last Tuesday.
What actually happens to AM over the next decade probably depends less on legislation and more on whether any of the remaining operators make a real decision to treat it as infrastructure rather than a declining asset to be managed toward zero. KNX staying on 1070 and staying all-news is a data point. One data point. But in a landscape where most of the news about AM involves companies trying to exit, a station actively occupying the band and doing actual journalism on it is at least evidence that the argument isn’t entirely hypothetical.
