Tactical Technology for TEOTWAWKI – Part 6, by J.M.

(Continued from Part 5. This concludes the article series.) Pilot of the Airwaves Another area where mobile electronics can provide some useful tactical functionality is communications, even if cellular networks and the Internet aren’t available. There are a lot of good articles here on SurvivalBlog.com about radios, so I’m going to focus on other areas. One very useful option for communications is a goTenna Mesh paired with each mobile device on your team. They’re around $180 a pair, but goTenna frequently has them on sale for 20% or more off. It’s a small device that you clip to the outside …

(Continued from Part 3.) There’s an App for That The ability to run thousands of different apps is where the power of a mobile device really comes into play. It allows you to have access applications, files, sensors and other things in the palm of your hand. One of the most obvious app uses for mobile devices in field operations is maps – you can use them to figure out where you are, plan you need to go, note your findings, etc. I’ve standardized on mapping apps that utilize Open Street Maps (OSM) data files and support GPX files for …

(Continued from Part 2.) It’s All in Your Hands The core component of my field technology system is what most people would call a cell phone or smartphone, but I prefer to call a Mobile Information, Communications and Control System (MICCS), or just mobile device for short. Why not call it a cell phone? – because the cellular network will most likely be one of the first things to go in a TEOTWAWKI scenario. Granted, you could potentially create your own cellular network if you have the money and expertise, but for the purposes of this article I’m going to …

(Continued from Part 1.) You Can’t Stop the Signal! Much of the gear I’ll be discussing utilizes wireless communications for remote control and data exchange, so there are a number of dynamics that need to be understood to maximize their use. First, there are the factors that impact every radio signal: Transmission power – The more power used to transmit, the stronger the signal and the further away it can be received. In the US the Federal Communications Commission (FCC) sets limits on how much power can be used to transmit. Antenna – The more closely the antenna is matched …

[Editor’s Introductory Note:  This lengthy and detailed article will be serialized into six parts.] I’ll admit it: I’m a techno-geek. Ever since I programmed my first computer in BASIC using punched paper tape many (many) years ago I’ve been fascinated by computers and electronics, and I’m always finding ways to leverage technology to improve various aspects of my life. I use RFID chips on many of my preps so I can locate them quickly, I’ve created an extensive database of all of my preps that includes type, quantity, location, storage bin, expiration/rotation date and lots more, and I’ve created a …


The Reality of Aging and Prepping – Part 2, by Muscadine Hunter

Now, let’s talk more about ham radio: Beginning in February, 1991 the FCC, in their infinite wisdom, did away with the Morse Code requirement for Technician Class Operators. What that means is there are nolw a lot of ham radio operators who do not know Morse Code. Why is this important? It takes a lot less technology and output power to successfully transmit a message using code. And if you have developed your own alphanumeric code for your group (as we have) then it is even harder to break if sent in Morse code because so many people now days …


The Reality of Aging and Prepping – Part 1, by Muscadine Hunter

To one extent or another I have been a prepper since I was in junior high school, 50 years ago. My dad was an avid outdoorsman who taught me to fish when I was old enough to hold a pole and taught me to shoot when I was 6 years old. By age 15 I was shooting skeet in state competition and began learning the art of reloading. I started bowhunting with a recurve bow when I was about 13 and had learned to make my own arrows, using blank shafts, by the time I was 15. Also, during my …


The Semi-Prepper – Part 2, by Francis

(Continued from Part 1. This concludes the article.) In addition I stress myself at the range by exercising when I get there (running, pushups, jumping jacks.)  The idea is to degrade my performance by tiring and winding myself, which will show me how I will shoot under stress. Since I’m now in my 70’s, I feel the best home defense weapon is a rifle. Semiautomatic pistols are great but a rifle with its’ longer sight radius leads me to be more accurate. Also as I get older I am concerned about the complexity of the “manual of arms” for the …


Working From Home: A Forced Sabbatical, by D. Glen

I work for a Fortune 100 company in the Midwest and work in the area of Research and Development (R&D). Late during the week of March 8th, we began to hear rumors that our facility and other staff locations throughout North America would be closing soon due to the CV-19 outbreak that was beginning to spread across the country. During the afternoon of Friday, March 13, the rumor was confirmed in that my supervisor stopped by to inform us that our facility was closing immediately and would remain so for three weeks until April 6th. Per the rumor, the closure …


Useful Transceivers for Most Preppers, by Tunnel Rabbit

Preamble The goal of this article to provide readers, the average preppers radio operator, with useful choices that may be capable of meeting a required level of performance. These are some inexpensive, or low power radio options that do not require an Amateur Radio License in the U.S.. Antenna choice is a very important to the part of providing reliable communications within a 10 to 20 mile radius using low powered radios. Terrain also plays an important role. If one located 50 feet higher than the average elevation of the surrounding terrain, the distance it may transmit and receive is …


Ready for TEOTWAWKI: What’s Bringing Us Along – Part 1, by K.G.

As we age, we need to understand our new limitations and be able to adapt to them, overcome the ones we can and add new skills commensurate with our abilities. The timeless adage “if I knew then what I know now” is quite applicable to my prepping and survival journey. The focus of this article will be on adding new skills that will complement our existing skill set so that we can still be of service and not just survive but thrive in a TEOTWAWKI scenario. The Importance of Family and Like-Minded Friends Having a wife and family members that …


Practical Survival Radio Communications – Part 2, by G.H.

CONTROL THE AIR Controlling the air often means transmitting, when necessary, large quantities of information accurately in poor conditions in a short amount of time. Even operators that are interested only in the hobby side of radio may fall into an emergency with the radio being the only source of working communications. Communications in an uncomfortable situation or actual emergency requires a much different style than “ragchewing” with friends on the radio as a hobby. If an emergency is the first time an operator faces a communication challenge, the likelihood of successful communications is poor. Practice, Practice, Practice Radio operators …

Like many families, the miles between me and my brothers are many. Fortunately, we hold a conference call every Wednesday evening to stay in touch. We have been doing this for nearly a decade. Realizing how important communications are to all of us, and from my role as the Logistics Chief for our County during major emergencies, I accepted the assignment of finding communication tools that will ensure communications no matter what. It did not take long to realize that radio communication works when all others fail. I obtained my amateur radio license and have the honor of recognition by …


Cold Weather Considerations – Part 6, by JM

20

Editor’s Note: This is the concluding installment in this article series. Firearms No article on prepping would be complete without some discussion on firearms, and using them in winter conditions can present some unique challenges. Firearms are precision machines made from metals and polymers, and cold weather can have some big impacts. The materials themselves can become brittle at extremely low temperatures, so you should avoid sudden sharp impacts if possible. Shooting a firearm can heat up the barrel and other parts pretty quickly and cold temperatures can cool them back down rapidly, which can cause weaknesses in the materials, …


Powering Tube Radios with Batteries, by Brian H.

DISCLAIMER: USE THE INFORMATION PRESENTED HEREIN AT YOUR OWN RISK. HIGH VOLTAGE DIRECT CURRENT, SUCH AS DESCRIBED BELOW, CAN BE LETHAL. IN ADDITION, EVEN SMALL GEL-CELL BATTERIES CAN PRODUCE HIGH CURRENTS WHEN SHORT-CIRCUITED AND QUICKLY MELT WIRE, DESTROY COMPONENTS, AND START FIRES. IF YOU ARE NOT FAMILIAR WITH ELECTRICITY, THEN ASK SOMEONE QUALIFIED TO CHECK YOUR WORK BEFORE ENERGIZING ANY OF THE CIRCUITRY DESCRIBED. Older vacuum-tube radios are popular in the prepper world (and rightly so) for their resistance to EMP damage. One useful fact about them that is often unrealized is that many of them can be powered by …
