And the auto-off feature turns the radio off after 90 minutes of play to help stretch its battery life. Most post-1932 commercial radios were superhets, and this technology is still in widespread use in radio receivers today, implemented with transistors or integrated circuits. The seven NOAA Weather Radio frequencies are preprogrammed on a separate dial for fast access during bad weather.

The AC/DC and USB chargers are useful for day-to-day use, but the Voyager really shines when the power goes out. A telescoping antenna helps ensure the best possible reception of FM and NOAA signals, while an internal antenna receives AM frequencies. Enjoy the durability of the MMR-88 while experiencing some of the key features that help make this part radio, part emergency beacon.I sold two complete sets of HVLP equipment a few years ago and I guess it's time to start looking for another set. Weather radios provide communication from the outside world and multiple other options like flashlights, phone chargers, and more to keep users prepared for almost any situation. Pick up this easy-to-use radio and you’ll be adding tons of versatility to your survival kit and setting a solid foundation.

This Philco car radio model was the first tubeless auto set in history to be developed and produced.As the designer of the TETRA security algorithms, ETSI does not consider that this constitutes a ’backdoor. Other farm radios were designed to run on 32 volts DC, from a bank of lead-acid storage batteries charged from a gas powered generator or a wind-charger. The fact that it works with conventional AA batteries makes it a bit more flexible than most of the other radios we tested, although the charge from AA batteries cannot be used to charge other devices. Still, it’s fair to say there are some poor-quality models on the market, so reading reviews and trusting a brand with certification from an organization like NOAA or the American Red Cross adds additional reassurance to the product. Even if the ER210 doesn’t contain a dog whistle for that extra level of shrill emergency sound, it has enough features to keep you engaged and learning.

Thanks to Trevor, we're now blessed with a simple device that still thrives, and serves countless uses today.

It can come in handy while you are camping, or you can sneak a listen to the big game out in the yard. We set up testing scenarios to simulate the types of real-world events, such as severe storms and power outages, that hand-crank radios are designed to meet. Still, people with questions can find a long list of local meteorologists and others who have created YouTube videos to answer any additional questions you may have.
