EMP attacks—that is to say, electromagnetic pulse attacks, in which charged particles like electronics charge accelerate abruptly and quickly, generating a shock of electromagnetic energy—make it impossible for electricity to work, in addition to batteries. Thus, should an EMP attack happen to you, you won’t be able to call for help, nor consult the Internet for information. You won’t even have the power to see, and depending on how strong it is, you might not be able to use your car. EMPs are a very real possibility: they have happened in 1962 and 1989.
In cases like these, how can you communicate during—as well as after—the attack? The first tip is that you should have a backup plan already in place, including all the equipment you’ll need to power through the attack. Such equipment includes weather alert radios, transceiver radios, and AM/FM radios. Depending on the strength of the EMP, AM/FM radios might still be working. As for transceiver radios, these devices can both send and receive information, which makes them highly useful when you need to coordinate with those nearby to prep together, gather your resources, and find anyone who might have gone missing. You should also have handheld scanners; these pick up traffic related to fires, police cruisers, and ambulances, and they also keep you informed on how events are progressing in your area.
You can also set up certain forms of two-way, short-distance communication: the Family Radio Service (which is compatible with store-bought walkie-talkies) and the General Mobile Radio Service (radios on this system are similar to those on the FRS, but have more range). If you’re interested in using the GMRS system, please be aware that you must get an FCC license for this; you can’t just own one.
You can also purchase a marine radio, CB radio, or HAM radio. However, be aware that CB radios tend to have a limited range, and as such might not always be ideal. You can also use a satellite phone, which is a phone that connects to satellites in the sky, rather than cell sites on the ground. Although these are pretty expensive, they can come in handy. Please be advised that they might not work in every environment; they don’t work inside, for example. EMP attacks have taken out satellites in the past, so this is also something you should be aware of. As for HAM radios, these are some of the best possibilities for limited communication that are available on the market. They do require an FCC license for operation, though—but you won’t regret getting one, since these devices are so useful.
When all’s said and done, we hope this info will help you in the (hopefully unlikely) event that an EMP attack strikes you area. But don’t forget: keep faith; keep each other safe. Your faith in each other will help you work better, coordinate your affairs more efficiently, and ultimately help you survive better in cases of disasters like these.
