Preparing for a Dam Breach, by A.B.S.

Many of my fellow Tennesseans awoke to headlines the other day that two of the Corp of Engineers dams in our area that are supposed to protect the people from floods and provide water and electricity are in danger of failure. Built more than 50 years ago, the Wolf Creek Dam and the Center Hill Dam overlook several hundred thousand people in central Tennessee, and are leaking significantly. The Wolf Creek Dam has been classified as being at high risk of collapse. The Wolf Creek Dam is located on the Cumberland River 190 miles up stream from Nashville. The dam …


Two Letters Re: Disseminating Local News and Information in a Grid-Down Societal Collapse

Jim, I think Brian raises a good question and your suggestion about using manual typewriters and mimeograph machines is a great idea. Here’s another one. While watching the the first season of Jericho DVDs, I noticed that in an episode titled “Black Jack” some of the characters went to a barter fair called Black Jack. They had to travel 200 miles to get to this town. The town’s fairgrounds were used as a barter fair location and in the middle (I assume the middle) was a tall board with a platform and a big roll of newspaper on the top. …


Letter Re: Disseminating Local News and Information in a Grid-Down Societal Collapse

James: I haven’t seen much information about this, so I ask you: How do you plan on “Getting the word out”? Once the ink/toner runs out of your printer, what will a survivalist group do? We’ve nearly lost the ability, and knowledge, to operate hand-presses. Moveable type suppliers are long gone, and there’s precious little available on eBay. Certainly not an entire printing press. You might find some blocks of moveable type, but not enough to actually make an entire flyer, book, or other piece of information, such as a book or even a Bible. And we can’t rely on …


Letter Re: Novel Recommendation–“Solar Flare” by Larry Burkett

Mr. Rawles, I have read your novel Patriots and passed it along to several people that I know. Most of them now own their own copy as well and it has been a big boost in helping them see the need for making preparations for the times ahead. It is with great interest that I have read the recent discussions about solar flares on the blog. The novel that first piqued my interest in survival and preparedness was the book Solar Flare by Strategic Air Command veteran and former NASA employee Larry Burkett. The premise of the novel is an …


Two Letters Re: Some Transceiver Antenna Questions

Jim, A few pieces of additional information about antennas: Quarter wave antennas are traditionally used for portable radios as they match the radio’s output impedance of 50 Ohms. By matching this impedance with an antenna of 50 Ohms you get maximum energy transfer. A 1/2 wavelength long antenna (twice as long as a 1/4 wave) has an impedance of several thousand Ohms and is not a suitable radiator unless you add some sort of impedance matching between the radio or the antenna. This can be in the form of a coil and capacitor or an antenna tuner. One advantage a …


Letter Re: Solar Flare Spike in 2012?

Jim:Regarding your recent interview on Fox Business about the significance of 2012: When I was a teenager, it was the Mayan 2012 [calendar] event that got me interested in preparedness. I ran with a bit of an impromptu Boy Scout like crowd (we weren’t Boy Scouts but our parents encouraged us to hunt, fish and camp). It was fun imaginary scenario when we were kids. I grew out of my Mayan 2012 phase. As an adult, I am preparing for a solar 2012 event. Essentially, a couple of years ago, I came across some research by a guy who was …


Letter Re: Some Transceiver Antenna Questions

Jim; By purchasing a 60-inch collapsible antenna, I was able to get a lot more range out of my hand-held transceivers, but that’s all I know. Can you give a short tutorial on antennas? What is a ground plane, when is it necessary? Would full wavelength be better than 1/4 wavelength? For a base system, would you recommend Yagi or something else? Thanks, – SF in Hawaii JWR Replies (Updated): To begin, one-half wave antennas are theoretically the most efficient. Shorter fractional wavelength antennas (quarter-wave, 1/8th-wave, et cetera) are used primarily for compactness and lower cost. I was told by …


Letter Re: Advice on Communications Scanners

Dear James, I was talking to my neighbor today and he showed me his Uniden Bear Tracker 800 scanner, a now discontinued model. That got me to thinking that I probably should get one for emergencies. But the thing is I don’t know what you should look for in a police scanner. Also I’m on a budget and I’m not willing to spend more than $100 on a scanner, but most cost quite a bit. That’s why I’m looking for a reasonably priced scanner, though I’m having problems finding one. Any recommendations or help would be gladly accepted. Regards, – …


Victory in the DC v. Heller US Supreme Court Decision–With Some Reservations

I was pleased to hear of the recent DC v. Heller US supreme court decision that affirmed that the “right to keep and bear arms” is indeed an individual right of all citizens. However, I was disappointed to see that the court used circular logic in their assumptions on what constituted firearms “in common use” Just as I warned back in March, (immediately following the oral arguments), the court relied on arguments made by Mr. Gura (the plaintiff’s attorney). In my opinion, Gura’s arguments were a disservice to American gun owners and “the militia at large”. (Which consists of all …


Letter Re: A Recent Fire Evacuation Experience

James: Last weekend my town was threatened by a pretty big fire. Dozens of homes burned, thousands of citizens were evacuated. My neighborhood was among those ordered to flee the advancing flames. (Drama!) My family was prepared to leave ahead of time and evacuated safely in large part because of the advice and encouragement I have found at SurvivalBlog. Thank you. I did learn a few things. Theory flies out the window when panic is in the air. What is organized and prepared ahead of time actually works, what is thrown together at the last minute tends to fall apart. …


After 10 Years–Some Observations and Lessons Learned by a Y2K-Era Prepper

It was June, 1998. Y2K was a salient topic of conversation. It got my attention. When the electricity went off and there would be no water to drink, and no fuel to move food to the JIT grocery stores, I could see things getting very ugly. I had been willing to fight for this nation as a member of the US Army. Now it was time to fight for my household. I bought a Springfield Armory M1A. I bought a safe to store it in. I bought another M1A (for the spousal unit of course!) I bought ammo. Lots of …


A Citizen’s Band (CB) Radio Installation Primer, by C.G.

Citizen Band (CB) radio requires no FCC license to operate so it is a good choice for local communication. If cell phones fail to work for whatever reason, it may be the best method for remote communication since its range is better than FRS and GMRS. When I installed my first CB in a vehicle, I was happy just to get it in and be able to transmit to my buddy who lived the next block over. I’ve matured since then and my tolerance for white noise is less than what it used to be. I’ve learned over the years …


Letter Re: Amateur Radio Frequency Bands and Licenses

Mr. Rawles, Concerning the mention under the “Communications Gear” category [in a recently-posted Profile]: “CB and base station with modified ham frequencies”. One bit of warning – if you don’t have a FCC Amateur Radio license, who do people think they are going to talk to on the ham frequencies? Amateur Radio is not the free-for-all situation that is commonly found on Citizen’s Band (CB). In addition to the FCC Rules & Regulations (Part 97), it tends to be very self-regulated. Even in an “emergency situation” you might find it difficult to find anyone willing to answer your bootleg transmissions …


Technology After TEOTWAWKI, by JLG in Texas

“A wise man has great power, and a man of knowledge increases strength; for waging war you need guidance, and for victory many advisers.” (Proverbs 24:5-6) Most survivalist planning focuses on physical needs—food, shelter, clothing, first aid, self defense. While the physical essentials rightly belong at the top of the list, there’s almost always some empty space left in the locker/bunker/trailer/back-of-the-truck for…something. What to put in there? Human beings are social animals, and we need each other; God has woven this into our genetic code. A “Lone Ranger” survivalist might have an edge in the short-term, but a group of …


Two Letters Re: Observations on a Tour of a Telephone Company Central Office

James: The batteries are why the phone still works when the power goes out. That is if you still have an old style (hard wire) phone and not all cordless phones. The cordless phones need 120 VAC power to run the base station. You should maintain at least one all wire somewhere in your house. I believe the [common design for COs is that the] whole building is built in such a way that it is a big Faraday Cage. It would take a pretty close proximity EMP to take one out. The EMP danger is in the above ground …
