The K.I.S.S. Principle and Transceivers – Part 2, by Tunnel Rabbit

17

(Continued from Part 1.) UHF Business Band Transceivers This is a more versatile radio than the Midland MXT400 that can access off the beaten path frequencies, and provides much better COMSEC (Communications Security). These can use the same antenna, cable, and adapters detailed for the GMRS transceivers. This type of radio can be programmed per your instructions by BuyTwoWayRadios.com, and the radio is easy to use and rugged. Our choice of frequencies are limited by the radio to the UHF band, and the limits of the antenna that covers only a section of the UHF band. We can also purchase …


The K.I.S.S. Principle and Transceivers – Part 1, by Tunnel Rabbit

64

Editor’s Introductory Note:  Because of the length of this detailed article, it will be serialized into five parts. — I’ll begin with a note of warning for those who would delve into, or recommend sophisticated radio equipment.  The learning curve can be steep, and it requires a significant investment of time to become competent. I recommend using the “Keep, Simple, Stupid” (K.I.S.S.) principle. The apocryphal originator of the K.I.S.S. principle was no simpleton. He was the aircraft design genius Kelly Johnson, and we should heed the advice. It is likely that simple-to-use equipment is the best choice for most. Here …


A SSB CB Thrift Store Score!, by Tunnel Rabbit

42

My advice is to keep checking the thrift stores. I went to town to sell eggs, and turned some of the egg money into a single-sideband (SSB) Citizen’s Band (CB) radio ($5), and 100 feet of new 75-ohm coaxial cable ($2.50). I can now get on the air for only for only $8.50! If I land one more of these, then I will consider modifying my Kenwood 830S 10-meter rig to 11 meter. I would then have a 100-watt rig with SSB capability to talk to my mobile SSB CBs. Having SSB mode CB would give me yet another redundant …


Gear Review: Three Hand Crank Radios, by The Novice

26

Many years ago, in a small town near where I live, a young family was gathered in their home. The weather had begun to look threatening, and they were concerned. Then, a growing rumble shook the earth and sky, like the approach of an impossibly large freight train. The family sought what shelter they could find. As the oncoming tornado shattered their house, the young father shielded his family with his own body. His family survived. He did not. One of the children whom that man protected grew up to be an acquaintance whom I greatly respect and admire. Many …


Sign Language as a Survival Skill, by B.R.

21

When I see and read all manner of survival books, magazines, online articles, I’ve noticed a major issue important to me that is never talked about at all, for the most part. What is this issue? In any survival situation how do the healthy, hale members of any society or culture communicate treat and work with our handicapped people/family members? For this article, I will concentrate on the deaf/hard-of-hearing citizens of our own country. As a being profoundly deaf man since the age of four, I have experienced numerous good and bad situations throughout my life. Sometimes the situations were …


Bypassing Internet News Censorship, by M.F.

41

In late 2019, I completed the ham radio Technician and General tests and to be honest I’ve yet to get started on the Extra Class test. if you are new to ham radio, then check out hamexam.org and sign up, it’s free. You can take your tests on a phone or tablet until your hitting 90s and then go schedule to take the test at a local comm center or ham club. They charge just $15 to test, and they often let you also take the next higher level test free of charge. I managed to buy and set up …


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

20

(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 …


Tactical Technology for TEOTWAWKI – Part 4, by J.M.

(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 …


Tactical Technology for TEOTWAWKI – Part 3, by J.M.

10

(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 …


Tactical Technology for TEOTWAWKI – Part 2, by J.M.

(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 …


Tactical Technology for TEOTWAWKI – Part 1, by J.M.

[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

34

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

32

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

34

(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 …
