A Scanner for TEOTWAWKI – Part 3, by Tunnel Rabbit

(Continued from Part 2. This concludes the article.) External Antennas, Detecting Potential threats at greater distances When using a scanner to sweep the band, or scan a list of frequencies, the scanner is much more sensitive and hears weak signals as well as strong signals. When using the Close Call feature that also sweeps the band, only strong signals that are very nearby (within 100 to 200 yards), might be detected. Some brands of scanners other than Uniden, may also have a similar Close Call feature, and might have more a sensitive receiver Sofware Defined Radio (SDR) frequency counter or …


A Scanner for TEOTWAWKI – Part 2, by Tunnel Rabbit

(Continued from Part 1.) ‘Sweeping’ a Band If one can afford to buy several scanners, then that would be optimal. We should have at least three, given the old adage: “3 is 2, and 2 is 1, and 1 is none.” We can keep one spare scanner in a Faraday cage, and store it elsewhere. Then use the other two scanners: One to scan from a list, and the other to sweep the band, or particular parts of a band. Each scanner will have an operator’s manual to help. If I could only sweep one band, then it would be …


A Scanner for TEOTWAWKI – Part 1, by Tunnel Rabbit

Introduction: Why Should We Use A Scanner? To most people, scanners could not be any more sublimely unimportant, and boring, and completely irrelevant pursuit of yesteryear. Especially as we have aged, and because the age of digital radio is here. Apparently, our old dusty scanner is obsolete. So why bother? Because security will be job #1. Scanning provides a golden opportunity to improve our situational awareness. We must do all that can be done to remove the element of surprise at a survival retreat. A simple scanner is one of those low-cost options that is a significant force multiplier. It …


Radios for Emergency and SHTF Use – Part 4, by Rufus King

(Continued from Part 3. This concludes the article.) A friend of mine suggested that I include some discussion of less costly MURS radios for those prepping on a modest budget. There are not nearly as many options for MURS radios as there are for GMRS. A bit of research reveals that a Hong Kong-based firm called Retevis offers Chinese-made radios that it markets for MURS use. Their model RT21V is available in a two-pack for $44.99. They are CTCSS capable, but they do not come with any tones already set up. The Retevis units have the five MURS channels ordered …


Radios for Emergency and SHTF Use – Part 3, by Rufus King

(Continued form Part 2.) General Mobile Radio Service (GMRS) GMRS is a personal radio service that uses the same frequencies and channels as FRS, but more power is allowed, and there are greater equipment options. The FCC defines GMRS as “A mobile two-way voice communication service, with limited data applications, for facilitating activities of individual licensees and their family members, including, but not limited to, voluntary provision of assistance to the public during emergencies and natural disasters.” 47 CFR 95.1703. Note that unlike FRS or CB, GMRS requires a license. 47 CFR 95.1705. There is no test, and the license …


Radios for Emergency and SHTF Use – Part 2, by Rufus King

(Continued from Part 1.) Back to the matter of radio spectrum: It is regulated by the government, and it pretty much has to be. No matter how libertarian you lean and no matter how dim your view of government power, somebody has to regulate the spectrum, or it would be completely useless, with would-be users interfering with each other left and right. Every developed nation has a government agency that allocates radio spectrum to different uses, and in turn countries cooperate internationally via various treaties and agreements. In the United States, this responsibility has been delegated by Congress to the …


Radios for Emergency and SHTF Use – Part 1, by Rufus King

I have been interested in radios since I was about 12 years old. Long before cell phones were ubiquitous, the adult leaders in my Boy Scout Troop all had CB radios installed in their vehicles on road trips, and I witnessed them being used to good effect for communication between vehicles. I know now that the 11 meter band and the AM operating mode of those radios is a suboptimal choice for that kind of short-range voice communication, but it was the practical choice when CB was about the only unlicensed radio service available. A couple of the scout leaders …


Seodon FRS Handheld Radios, by Pat Cascio

Ever since I was a little kid, and built my first walkie-talkie (CB radio) – and the darn thing actually worked – I’ve been fascinated with radio communications with other folks. Of course, CB radios, are mostly a thing of the past now – everyone has a cell phone – but a good two-way radio certainly has its place for Preppers. I spent considerable time searching for what I hoped would be an economical set of fairly reliable compact two-way radios, that would serve my purposes, during a SHTF scenario. Of course, price is always a consideration for me. We …


U.S. Military Field Phones, by Ken in Michigan

If you are looking for a secure communication system for your farm, ranch, or retreat, then look into a military phone system. You can create an ideal communication system, any size, from two positions overnight to multiple positions in a large permanent retreat. Military Field Phones (“MFPs”) do not require external power. They are designed to operate in adverse conditions and most importantly, do not emit any electronic signal. MFPs cannot be overheard by radio scanners or radio direction finders. MFPs keep your location undetected by electronic surveillance, unlike today’s radio communications that can be overheard and DF-located using today’s …


RF Scanning for Preppers – Part 2, by R.W.

(Continued from Part 1. This concludes the article.) — Scanner Models When radio systems were still purely analog, there were many manufacturers vying for your attention to buy their scanning receiver. With the costs of developing digital-capable receive technology and a dwindling user base, the market has collapsed to just two manufacturers of multimode (analog and digital_ scanning receivers: Uniden and Whistler. Uniden, having been one of the pioneers in consumer electronics developing dozens of models over the past 40 years, currently has twelve scanner models available while Whistler offers six. For those who might want to dip their toe …


RF Scanning for Preppers – Part 1, by R.W.

Sir Franics Bacon is attributed with saying, “Knowledge is power.” And nothing could be more true than when it comes to prepping for emergencies and SHTF situations. When the forces of nature or the whims of men (or women) turn life upside down, we need to have a plan for reacting. If you’re reading this then you, more than anyone else, understands how true this is. For those who are unprepared it can literally mean the difference between life and death. Shortly after I began writing this article the people in Texas were put to the test with massive loss …


Basic Computer Privacy and Security, by Liber T. Y.

First of all, a few disclaimers: 1. I am not a computer geek and I am not good at coding. I am merely a layman who has found some useful tools for computer privacy and security and knows a thing or two about computers (I’m also not a lawyer so any legal ramifications should be talked about with a legal professional). 2. This article is about what a layman can do to secure their computer and browse privately in the Windows operating system (OS). As such, not all of the products listed herein may work in an Apple or Linux …

(Continued from Part 4. This concludes the article.) ANTENNA SELECTION Mobile Antennas Selection, and Mounts The following list is very short list as most antennas on the market require the installer to tune the antenna with an SWR meter.  Often this fact is omitted. Fortunately, both these antennas do not need to be tuned and are more than adequate.  There is not much need to look further. Both of these antennas have NMO bases, and there is a variety of heavy to light magenetic mount with various cable lengths available that have MNO fittings.  Magnetic mount bases are very popular, …

(Continued from Part 3.) The Quad Barreled Cannon, The Wouxun KG-UV980P, $310.00 The Wouxun KG-UV980P Quad Band Base/Mobile Two Way Radio is a quad band, with cross band repeat, a 50 watt transceiver, that transmits using FM only in these frequency ranges: 26 to 29 MHz, 50 to 54 MHz, 136 to 174 MHz, and 400 to 480 MHz.  It can generally be described in terms of Amateur Radio as a 10 meter, 6 meter, 2 meter, and 70cm, yet this unit transmits outside of these Amateur bands, and is much more than simply a Ham radio.  For example, it …

(Continued from Part 2.) Editor’s Note: The following section of the article describes some high power and out-of-band transmission modifications that are not legal under most circumstances. In an absolute disaster situation, anyone can operate outside of normal bands/channels without a license and probably without any legal repercussions. But doing so in normal times will surely get someone arrested, their gear seized, and some hefty fines. Beware! BACK TO THE FUTURE, CB RADIO IS BACK! Although Citizen Band (CB) might not be a part of our primary radio communications plan, we may need to operate a CB to talk to …
