You’re staring at a dead phone screen. The power went out three hours ago, the cellular towers are bogged down because everyone else is also trying to refresh Twitter, and your "smart" home is currently a collection of expensive bricks. It’s quiet. A little too quiet. This is usually the exact moment people realize they messed up by relying entirely on the cloud for information.
Honestly, we’ve become obsessed with high-speed data, but when things actually hit the fan, the humble AM FM battery radio is the only thing that consistently works. It’s old school. It’s analog. It’s basically a box of magnets and wire that pulls information out of the literal air.
People think radio is dead. They’re wrong. According to Nielsen’s 2023 Audio Today report, broadcast radio still reaches 82% of Americans every single week. That’s more than smartphones, more than TV, and way more than any streaming service you’re currently paying $15 a month for. There is something fundamentally "uncancelable" about a radio wave. It doesn't need a 5G handshake. It doesn't care if your ISP is having a bad day. It just plays.
The weird physics of why AM and FM actually matter
We should probably talk about why you need both. AM and FM aren't just two different ways to hear the news; they are entirely different animals when it comes to physics.
AM, or Amplitude Modulation, is the workhorse. These waves are long. They’re slow. They can literally bounce off the ionosphere—a layer of the Earth’s atmosphere—and travel hundreds of miles at night. It’s called "skywave propagation." You could be sitting in a cabin in the middle of the woods in Pennsylvania and pick up a clear signal from a 50,000-watt "clear channel" station in Chicago or Cincinnati. This is why AM is the king of emergency broadcasts. If the local infrastructure is gone, the distant signals still get through.
FM (Frequency Modulation) is the opposite. It’s line-of-sight. The waves are shorter and more robust against static, which is why your music sounds better on FM. But FM doesn't bend around mountains well. It doesn't bounce off the sky. It’s great for local high-fidelity news and weather updates, but if you’re in a deep valley, your AM FM battery radio is going to be leaning heavily on the AM side of the dial.
Why batteries are better than built-in lithium packs
Here is a hill I will die on: Stop buying "emergency" radios with internal, non-replaceable lithium batteries.

I get the appeal. You plug it into USB, it charges, it’s sleek. But lithium batteries have a shelf life. They degrade. If you leave that radio in a drawer for three years, there’s a massive chance that when you actually need it, the internal cells will have bloated or lost their ability to hold a charge.
A traditional AM FM battery radio that takes AA or D-cell batteries is superior for one reason: shelf life. High-quality alkaline or lithium AA batteries can sit in a package for ten years and still be at 90% capacity. In a real-world disaster scenario—think Hurricane Ian or the 2021 Texas power grid failure—you want a device where you can just "swap and go."
- AA Batteries: Easy to find, cheap, and you can scavenge them from TV remotes if you’re desperate.
- D-Cell Batteries: These are the heavy hitters. A radio like the Sangean PR-D4W uses D-cells and can run for literally hundreds of hours. We’re talking weeks of intermittent use without a battery change.
- Solar/Crank Backups: These are okay as a third-tier backup, but have you ever actually tried to crank a radio for 10 minutes just to get 2 minutes of audio? It sucks. It’s exhausting. Buy the batteries.
Picking the right hardware (Don't buy junk)
Most of the radios you see in the checkout aisle at big-box stores are garbage. They have "drift," which means you tune into 101.1 FM, and ten minutes later, the signal has wandered off and you’re listening to static.
If you want something that actually works, you look for DSP (Digital Signal Processing). Even on a manual-dial radio, a DSP chip helps lock onto a signal and filter out the electronic noise generated by your neighbor’s cheap LED light bulbs or your own microwave.
Companies like C. Crane and Sangean are the gold standard here. The C. Crane CC Radio 3 is widely considered one of the best AM performers ever made. It’s expensive, sure. But it can pull in signals that other radios don't even know exist. If you’re on a budget, something like the Sony ICF-P27 is a tiny, pocket-sized AM FM battery radio that costs less than a pizza and will probably outlive most of your modern electronics. It’s simple. One dial for volume, one for tuning. That’s it.
The "Information Blackout" myth
People assume that if the internet goes down, the radio stations go down too. That’s rarely the case.

Broadcast stations are part of the Emergency Alert System (EAS). Most major transmitters have massive diesel generators and enough fuel to stay on the air for weeks. They are designed to be the "last man standing." During the 2003 Northeast Blackout, which took out power for 50 million people, radio was the primary way people found out what was actually happening. While cell networks collapsed under the weight of "What's going on?" calls, the airwaves remained clear and informative.
Dealing with interference in a digital world
The biggest enemy of your AM FM battery radio today isn't a lack of stations; it's "RFI" or Radio Frequency Interference. Your house is a noisy place. Your laptop charger, your smart fridge, and those "energy-saving" light bulbs all spit out electromagnetic interference.
If you’re trying to listen to a distant AM station and all you hear is a buzzing sound that sounds like a swarm of angry bees, that’s RFI.
The fix is usually low-tech:
- Move the radio closer to a window.
- Get away from the "wall warts" (those big square power plugs).
- If you’re using a portable unit, physically rotate the radio. AM radios have an internal ferrite rod antenna. The direction the radio is facing matters. Sometimes a 90-degree turn is the difference between static and a crystal-clear voice.
More than just emergencies
I don't just use my radio when the lights go out. There is a psychological benefit to "linear" media. When you stream a podcast or Spotify, you are in a bubble of your own choosing. It’s an algorithm.
Radio is different. It’s communal. You’re hearing what everyone else in your city is hearing at that exact moment. There’s something comforting about a local DJ talking about the traffic on the I-95 or a high school football score. It grounds you in your physical community. It’s "slow media." You can’t skip the ads, you can’t fast forward, and honestly? That’s kind of a relief. It forces you to just listen.

Actionable steps for your home setup
Don't wait for a storm to figure out if your radio works. If you're serious about being prepared—or just want to enjoy some local broadcasts—here is what you should do right now.
Buy a dedicated unit. Don't rely on a "multitool" that has a flashlight, a compass, and a radio all in one. Those are usually mediocre at all three things. Get a dedicated AM FM battery radio from a brand that specializes in audio. Sony, Sangean, and C. Crane are your best bets.
Stock the right juice. Get a 12-pack of Energizer Lithium AA batteries. Unlike standard alkalines, lithium batteries won't leak acid and ruin your electronics if you leave them in the drawer for years. Keep them in the original packaging next to the radio.
Map your stations. Take 20 minutes on a Sunday afternoon to scan the dial. Find out which station is your local "LP-1" (Lead Primary) for the Emergency Alert System. Usually, it’s a big AM station. Write that frequency on a piece of masking tape and stick it to the back of the radio. If things go sideways, you won't want to be hunting through static to find the news.
Test for RFI hot spots. Walk around your house with the radio on. Notice where the static gets louder. You'll probably find that your kitchen is a dead zone because of the appliances. Knowing the "quiet" spots in your home now saves you frustration later.
Radio isn't a legacy technology. It’s a resilient one. In a world that’s increasingly fragile and dependent on complex server farms, having a simple battery-powered receiver is the ultimate hack for staying informed. It’s cheap, it’s reliable, and it works every single time.
