As the world becomes increasingly more reliant on technology, the threat of an EMP attack looms larger. An EMP, or electromagnetic pulse, is a burst of electromagnetic energy that can fry electronic circuits, rendering them useless. A powerful EMP could take out all of the electrical grid, leaving us without power, telecommunication, transportation, and all the other things that make our society function.
If you’ve done much studying into what will happen after an EMP attack, you’ll have quickly found that the short answer is “no one knows.” While there has been extensive research on the topic, and many educated guesses, no one really knows for sure. But, this article will guide you through some basic details of an EMP event that will allow you to know how a CB radio can still work during these times.
So, what would happen if an EMP struck? Would our CB radios still work?
CBRadios work by sending and receiving radio waves. These waves are not affected by an EMP, so CB radios would still be able to communicate after an attack. However, the power grid would be down, so CB radios would need to be powered by batteries or generators.
While CB radios would still work after an EMP attack, they would be limited in range and power. Without the electrical grid to amplify the signal, CB radios would only be able to communicate with other radios within a few miles. And without power, batteries would only last for a few hours.
In the event of an EMP attack, CB radios would be an important lifeline for communication. However, they would be limited in their range and power. It is important to have a backup plan for communication that does not rely on electricity, such as ham radios or shortwave radios.
What happens to electronics after an EMP?
Many of the devices that you own, including home appliances may fail after an EMP attack. They fail because the semiconductors built into these devices heat which causes damage to the electrical components. However, to help protect these expensive items you can buy surge protectors.
Does surge damage electronics?
A power surge can damage any electrical component or appliance in your home that runs on 120 volts or less. Any cord or cable on an electrical component could also be damaged, which can cause spark and fire.
Will a power surge damage my hard drive?
Yes, a power surge will damage your hard drive. Unplug any external hard drives. Disconnect any USB devices, SD cards, or flash drives. Detach any printers, scanners, or other peripherals. Power down your computer and unplug it from the wall. Open up your computer case and remove the data cables from your internal hard drives.
Can my TV explode due to a power surge?
Even if the surge only lasts for a microsecond, it can leave long-lasting damage. If the voltages get too high, your TV can malfunction permanently. With a power surge, your TV can turn on and off, or be entirely unresponsive. Even when you plug it back in, your TV may not display an image.
How do you discharge a power surge?
Unplug Electrical Devices To Bleed Off The Power Surge. The most straightforward way to control a power surge is to remove all electronic devices when the lightning starts. Leave your computer, televisions, washer, and dryer off until the storm passes.
How do you communicate after an EMP?
The best option would be investing in a radio (short and long wave) like this CB radio here or a HAM radio, or both. Paired up with your more basic walkie talkie for short range communication, you should do just fine with communicating after an EMP.
How can you test the quality of inductors?
For the best measurement of inductor quality, the impedance must be measured at frequencies covering the DC through the RF range. The Wheatstone Bridge is the embodiment of inductance testers. It is versatile. The only drawback is that its accuracy can drop at the extremely high or low ends of the frequency range.
Final Thoughts
So, in summary, if you’re looking for a way to keep in touch with your fellow homesteaders and friends following an EMP attack? Well, CB radios are the obvious solution, but it’s good to know that they will also work after the electromagnetic pulse has destroyed the electronics of your country.
