How to Select Two-Way Radios For an Off-Grid Emergency

When there’s a wide-scale disaster like a hurricane, earthquake, or flood, how do you communicate with others to get help? How do you reach out to family and friends to check on them and to see if they need assistance? During these catastrophes, the power grid may go down and cell towers may be inoperable. In such cases, you might not be able to rely on your cell or smart phone or landline.

That’s where two-way radios come in. They’re one of the most reliable means of communication not only during emergencies, but also when you’re off-grid in the middle of nowhere or outdoors.

Two way radios, then, are also necessities when you’re hunting, backpacking, or fishing, as well as other recreational activities where you can’t control the environment.

During these emergencies or outdoor sports, two-way radios may be the only devices that function.

Packing these radios in your survival or emergency kit will give you security and peace of mind. All you need to do is turn your radio on, push the talk button, and you’re ready to instantly communicate with a loved one or friend.

What are Two-Way Radios?

They are radios that have the ability to both receive and transmit a signal, allowing someone to have a conversation with multiple people who are on the same radio frequency. This is unlike a cellphone where you can only speak to one person at a time.

Two-way radios are relatively inexpensive and able to take a beating. They carry no user or roaming charges, contracts or monthly plans.

Two-Way Radio Features


Two-way radios are usually powered by NiMH rechargeable batteries. Most also accept alkaline disposables, which are inexpensive and extends your battery life. During emergencies, these back-ups can be a lifesaver.


Your radio should be weatherproof, able to withstand rain. However, waterproof devices are better. They won’t malfunction even after they’ve been submersed in water. You might also want a radio that can float. The buoyancy allows for easy retrieval if dropped in water.

Weight and Size

It’s more comfortable to stow your radio in a backpack or survival kit if it doesn’t weigh much. And a compact radio means you’ll be able to carry it in your hands.


Manufacturers often claim their ranges to be around 30 miles. Then, when you test the radio, you might only get a mile and that anything over is just static.

Ranges can never be achieved in the real world. The high estimate is based on optimal conditions, when the radios are in the same line of site, and without obstructions. Trees, rocks, hills, and mountains will impede your range. Climactic conditions, metal surfaces, topography, walls, buildings and houses will also impede your range.

Family Radio Service (FRS) bands have shorter range (around 5-6 miles) but don’t require a license.
General Mobile Radio (GMRS) bands, which are more powerful, with a range between 8-25 miles, require a license.

Emergency features

Radios with Emergency Alerts send an emergency signal to other radios in your group.

Radios with a flashlight are helpful in emergencies, like when there’s a power outage.

Voice Activated Transmission

You don’t always have hands free. Voice operated transmit (iVox/Vox) turns your radio into a speakerphone instantly, allowing for hands-free communication.

Weather Alerts

Weather updates or a built-in NOAA (National Oceanic and Atmospheric Administration) weather radio from the National Weather Service is essential during disasters like winter storms and flash flooding.
