Back in the Cold War days I was involved with uk civil defence. In my loft space I had a large aluminium EMP proof case containing …… I do not know. When the Berlin Wall fell, a few months later it was crushed without me ever knowing.

I find the American obsession with surviving war totally laughable. I’m sorry, but people are really building nuclear bunkers, and wrapping their Baofengs in foil and burying them in the garden? The trend seems to be people want dirt cheap radios, costing as little as possible, but are now trying to keep them working after somebody drops a bomb? Really? If I advertised a radio here in the UK, saying buy this radio, stick it in an EMP enclosure and hide it away just in case a war started I’d be on National TV as a loony, and the ■■■■ of a million jokes. Does average Mr America believe EMP damage soon is this likely? It makes America and Americans look a bit er, xenophobic and panic stricken. I’ve mentioned ‘go bags’ to people here and nobody has ever heard of this kind of protectionism. The vast proportion of UK residents live within overnight fallout distance from a USAF air base, and even our loony left politicians don’t even talk about bombs. Sorry guys, but you really are suffering from paranoia.

Perhaps insults should be left for off-forum communications.

Insults? Let’s not go woke. My point is that we have got to the stage where hobby users, because I don’t see business users talking about the doom and gloom that is really approaching paranoia levels. Perhaps my a British levity around all things bad is not appreciated, and for that I apologise. Firms in the US are making end of the world products and people are buying them. The magnitude of EMP is such that we could line a Jiffy bag with tin foil meant for turkeys and sell it as a product to put your Baofeng inside to save your radio. In most countries we don’t have ‘preppers’. In the UK you will sell your lined Jiffy bag if you advertised it for keeping your car key fob safe from the crooks with receivers to steal your car, but market it as a product for EMP protection and you’d go bust. I’m old enough to remember the Cold War, and how close we came. Nothing now reminds me of this. I’m sorry folks but the US has gone mad. I had to google SHTF which I heard in the podcast. If, people believe a nuclear war is about to happen, I’d suggest people might like to engage their brains. Our press think every American has at least two or three metal ammo boxes under their beds, so the entire point of using a Faraday based screen is to prevent RF getting in or out with a low resistance path surrounding the devices being protected, with any gaps smaller than the wavelength of the field. With an all metal ammo box this is pretty simple to achieve.

If you really want to protect your equipment it’s not that hard. The trouble is when you do protect it, what will you use it for? No electricity to charge batteries, no repeaters, so you can talk to other like minded souls within a few miles of you. What exactly would you be talking about ? EMP devices, detonated in the air mean any protected devices wont be that useful as the services in general within the area wont be working, so comms isnt that useful.

I’m saddened nobody is seeing the funny side of this discussion. Keeping in mind what training I had in the 80s, I should be wrapping radios up, and I have hundreds in boxes in the store. I suspect two way radios could also stand in their warehouse and be loading all sorts of their stock into EMP proof storage. From the undercurrent of the podcast, I suspect they are not.

Viewed from abroad, the people in the US have been viewing Mad Max as a documentary. Nothing I read makes what they do even understandable. It’s brilliant of course for the people who build nuclear bunkers!

No offence is intended against the majority of folk who have balanced views on the world, but Dr Strangelove is alive and well it seems.

I am probably the least woke person you would ever meet. I was in the military during the 70’s and visited the UK several times. As far as being prepared, well, maybe our country has a few different thing to be concerned about. Two years ago the state I live in had the largest wildfire in our history. I live in a small mountain town. The utility company shut off the power for safety reasons and it stayed off for a week. We were in a evacuation “warning” area as were my oldest daughter and her family . after a couple of days the cellular service went down. We were able to keep in touch with our family using GMRS radios. Had we not been prepared with store food and water we would have been in a bad way. When we were forced to leave our home by mandatory evacuations orders we were able to communicate with the family until we were out of the mountains and had cell service.

Since that time The utility company shuts off power when there are high winds multiple times. One of those times we, again, lost cell service. During those times without power there were unscrupulous people breaking into houses and looting homes. Not much of this made the news. So when you refer to people who discuss EMP protecting they are the ones who prepare for the other stuff as well. They are the people that might be able to help others whether it be during wildfires, earthquakes, hurricanes, and yes, even something as outlandish sounding as an EMP.

I read your replies and your threads and I enjoy your humor. I was told once that every time someone makes a joke there is a little bit of truth in it. This post was not the first time you have questioned our sanity over here, even if in jest. Go ahead and count me with those loony Americans.

Thanks for taking the time to reply, and I do understand the natural disaster point. Oddly, we did actually have an official from every regional area of the UK tasked as the emergency planning officer, who liaised with CB groups, hams, St. John ambulance and the Red Cross, plus marine groups to offer emergency services for natural disasters, and they did get used, but this person’s status was reduced drastically from the Berlin Wall removal. Councils now have this job still on the books, but staffed by recent graduates at just over McDonalds pay levels, often a shared role. If we have real disasters, it will go badly wrong and the links to volunteer groups have largely gone, and are untested. When the US were stationing weapons all over the UK we had big very loony ( in my opinion) groups opposed to it, but now these bases are closed, even these groups have virtually shut up shop. Nobody under 25 has ever heard of them. Maybe it is the size of the US that makes these things more vital, but I take the emergency point you made and see how that fits in.

I suppose, jokes out of the way, I wonder why the massive threat of the time up to the Berlin Wall collapse hasn’t reduced concern. I accept that the world would make the detonation of a bomb by radicals possible, but the delivery systems mean it’s world powers of super size who are the only real threat to all of us. People who live in very sparsely populated areas were not targets anyway, unless near one of the ‘problems’ like armed forces bases and the nuke sites. The radicals wouldn’t focus on those areas anyway, and if you live in a city, you seem to also be the kind of person who doesn’t dig holes and build up arsenals of weapons.

What we outsiders see is a powerful country with a lot of people upset about the way the world is, including their own government. You have laws allowing one person to own more weaponry than the county I live in has! We see the crazy ones use it too, then we see others so worried about war doing their stuff. I keep trying to think how we would feel if our country had these thinks and I can’t. I see a country scared of war but quite keen to protect themselves from one by making other people think they wan5 to start one?

That is an outsiders viewpoint based on what I see and read. Of course I have no way to know how common these views are, or what an ordinary American even is now. One of my ex-students and good friend lives in California. Over ten years he has changed, drastically. He now thinks differently.

I don’t want to annoy anyone, so I’ll not comment any more on this kind of stuff because I don’t want to annoy you folk, but now it’s spreading to two-way radio and their customers are buying EMP proof gear, that really worries me. It’s good for sales of course, so they’re giving customers what they are asking for so I don’t blame them, but the people buying the stuff concern me. If people have a genuine concern that makes them buy products for the doomsday scenarios, with nukes flying everywhere, something is wrong. Should us Brits worry about what is going on in our USAF bases. Nobody does at the moment. You guys on here I think are level headed and normal, whatever that means, but if you do see nuclear issues as likely and possible, and are not nutters, then us outsiders have missed the signs and signals you have used to form your opinions. Probably just a cultural thing so we can’t really ever understand each other. Keep safe folks. I’ll leave it now.

To be fair, prepping is certainly not an “American obsession”, nor is it an interest limited to America alone. An unofficial estimate of the size of the prepper community here in terms of percentages is well in the single digits. However, considering current events, it’s not surprising that interest in disaster preparedness is probably growing. It’s a large country with vast expanses of rural areas, particularly in the west. Many have experienced localized disasters first hand, and those who were fortunate enough to prepare beforehand were quite thankful they did.

It is certainly not the exclusive domain of Americans, either. I understand Australia has a fairly large prepper community, as does New Zealand. This is certainly understandable, as most of Australia is pretty wild territory and requires some prep and survival skills to navigate and manage. New Zealand has had more than their share of disasters and emergency events, so it’s no wonder their prepper community exists.

Sure, paranoia does exist in the prepper world, but the assumption that all preppers fall into that category is a bit of an overstatement. Having ridden through a number of hurricanes myself, I can assure you that there is nothing wrong with being prepared for “the big one”.

As I said in the podcast, I’m not as concerned about a nuclear “doomsday” scenario, but I think that natural or cyclical events such as extreme solar flares, which have and will occur from time to time from a scientific point of view, and which have been proven to cause some disruption historically, are practical reasons to at least consider a preparedness plan.

After all, as the sayings go, an ounce of prevention is worth a pound of cure. Better to have it and not need it, than need it and not have it.
