EMP Reminder: Faraday cages. Plus Communications After EMP
Howdy GLP,

Lots of talk of EMP. Remember to keep your electronics protected in Faraday cages. AM/FM, SW, (smaller) HAM radios, laptops, solar chargers (if possible), and so forth.

Metal garbage cans, steel gun safes and old surplus ammo cans are quick and easy Faraday cages. DIY Faraday cages for larger/specialized equipment.

Loose topic so add in anything related that you want. Just a heads-up, especially for those of us new to HAM radio and post SHTF.

Look into solar power for recharging.

A solar flare would send us back a few hundred year for about a year as the entire world loses electricity.

That is if the world can get their shit together and fix the power.

If not it would set us back for longer than a year.

My guess is a huge percentage of the population would die.

And we're due a solar flare.

Be sure to ground the faraday cages.

Wired to an outlet box

Drive a 3 foot conductor into the ground and clamp a wire to it

Some plumbing are grounded. As long as there were no PVC inserts from a repair on the conductive pipes separating from earth ground

Gas lines are grounded


If you have a ham radio you certainly should have a good ground available.

True that!

A lot of HAMs will take a hit, as I’m not sure repeaters etc. are EMF protected, but if ‘locals’ keep their basic HAM equipment EMF protected at least you may be able to get a tip off on something coming, link up with like-minded folks for protection, and so on.

 Quoting: zestor


You're talking about small solar flares.

I'm talking about a big one like the one in 1859.

On Sept. 2, 1859, an incredible storm of charged particles sent by the sun slammed into Earth's atmosphere, overpowered it, and caused havoc on the ground. Telegraph wires, the high-tech stuff of the time, suddenly shorted out in the United States and Europe, igniting widespread fires. Colorful aurora, normally visible only in polar regions, were seen as far south as Cuba and Hawaii.

Earth's magnetic field normally protects the surface of the planet from some storms. In 1859, the planet's defenses were totally overwhelmed. Over the past decade, similar but less powerful storms have likewise busted through, giving scientists insight into what will eventually happen again.

 Quoting: Tennessee Patriot


Open voice comms may be a problem, the groups I work with are concentrating on digital radio.DMR is much more efficient since it uses a fraction of the bandwidth of FM voice. The extra steps needed to program a DMR radio helps throw road blocks in the path of anyone trying to eavesdrop.

That said, security through obscurity isn't good enough, and many of these cheap chinese made DMR radios have encryption available. Using encryption over amateur radio is not allowed, but if things go hot and the rule of law isn't to be found I doubt anyone will be giving anyone else a hard time of the use of encryption.

Many people thing DMR is to be used over the internet and fumble around with hotspots and such to wormhole through the interwebs, but the real power comes from being able to hide your signal in plain sight.

Check out the radiooddity GD-77, DMR with available encryption for @ $80. They are decent little radios, a little more than the common boefeng, but worth it for the extra features.

Be sure to ground the faraday cages.

Wired to an outlet box

Drive a 3 foot conductor into the ground and clamp a wire to it

Some plumbing are grounded. As long as there were no PVC inserts from a repair on the conductive pipes separating from earth ground

Gas lines are grounded


If you have a ham radio you certainly should have a good ground available.
 Quoting: Nonentity

I disagree with this advice in the strongest possible terms. The telluric currents induced in the earth by an NEMP are considerable, and anything connected to a ground rod may well be affected by them. Simply placing equipment in a cardboard box and wrapping the box with several layers of aluminum, then taping it securely, is sufficent. There is no need to ground it. Commercial/industrial faraday cages are indeed usually (but not always) grounded, but they are not designed to deal with an NEMP that can induce strong ground currents.

I've actually buried a metal trash can into the ground, sticks up only enough to put the lid on. This is inside a metal shop for double protections.

I keep 3 transceivers, along with their associated accessories in the box. I've also got AA, and C,D cell batteries, a windup radio, and a small solar charger stashed away in there. I've tried to standardize USB connections for charging wherever possible.

What else should I be protecting?
