Four Letters Re: EMP Preparedness and Countermeasures

Dear Mr Rawles: I have been enjoying your SurvivalBlog very much. I am new to these kind of web sites but have been of a preparedness/survivalist mindset all my life. I served in the US Navy for seven years as an Avionics Technician on both fixed wing (FA-18 Hornets) and rotor wing aircraft. Part of my training encompassed electromagnetic pulse (EMP) and its effects on aircraft and how to properly maintain and repair them so as to not compromise their ability to withstand EMP should it occur. Now that I have been out of the military for some time I …


Letter Re: Cell Phone Coverage Maps as a Tool in Choosing Retreat Locales

Greetings, Jim: Several times you have mentioned using “lights of the night sky” [satellite] pictures to show where people are centralized ([assuming that a greater concentration of] people = trouble) in choosing where not to live/retreat. I have another suggestion: the maps of cell phone companies of their cell coverage. Cell phone coverage means lots of people or major travel routes. if a person wants to find a place to get away from people then looking on the no coverage area of cell phone maps is one tool to use. thanks for a great web site and great books. – …


Letter Re: Who Can Supply Sturdy Headsets for FRS Transceivers?

Mr. Rawles; I am having problems finding reliable headsets for Family Radio Service (FRS) radios. Do you know anyone I can ship mine to and have something made that will last and work? I got Radio Shack models and the headsets do not last a year of steady use. I got one model you cannot get headsets for anymore. The headsets cost $25 each and having to continuing purchase them is getting ridiculous. Even with Radio Shack warranties, if the SHTF you cannot run to them to get replacements. I am willing to pay for quality headsets to last in …


Reader Poll Results: Your TEOTWAWKI Resume — 100 Words and 100 Pounds

Some of these stretched the 100 word limit. (I skipped posting one that rambled on far beyond the limit.) The poll’s premise in a nutshell: “If someday you went to the gates of a survival community post-TEOTWAWKI and pleaded the case for why you should be let past the barricades and armed guards to become a valuable working member of the group, would you get voted in? Taken objectively, would you vote yourself in?”   I am a shoe maker (not just a repairman) can repair saddles tan leather have done ranch work mechanics weld gardening skills set a broken …


Letter Re: Hidden Retreats Versus Open Fields of Fire/Visibility

Hello; Thanks for your efforts and the structure of your blog. I appreciate the lack of flaming and demeaning commentary. Wanted to get more input on this subject ” Hiding retreat versus open fields of fire/visibility”. We are leaning towards camouflaging, as much as possible views of our home from the road. However, this conflicts with my Army provided training, where on fire bases, we have open fields of fire and high visibility. I believe we need a compromise. As a less than visible retreat will avoid [confrontation with those who are] the less observant. But open fields of fire/ …


Letter Re: Running a Laptop from a Jump Pack in a Short Term Emergency

JWR: Through a minor power disruption event, I made some discoveries that I thought I would share. A laptop computer can be run by an inverter of proper size. A laptop can be powered by a jump pack with a 12 VDC power port. The jump box can be recharged by a hand crank 12 VDC generator. We were able to continue e-mail and business communications, since the wireless towers are generator backup powered. This is good to know in local or short term disasters. – JG JWR Replies: Thanks for mentioning that topic. In my experience, running a laptop …


Letter Re: The Importance of Proper Hearing Protection

Jim: Regarding the [recently mentioned] Peltor tactical 6S (sound trap) [electronic earmuffs]: While the battery power for these is somewhat of a concern, they are well worth what you might spend keeping a few extra sets of AAA rechargeables (two for each ear) around. I, too, have been running these muffs for a number of years and really like them, especially under a helmet. The radio part works well too. On the qualification range with all the M4s going off, you can hear a hammer fall. So here is my quandary and request for advice. I’ve tried NiCd and NiMH …


Letter Re: Great Results with MURS Band Handheld Transceivers

Sir: I got two MURS radios from Rob [at $49 MURS Radios] and I am very pleased with these radios. They are in great shape and even though I live in the mountains of Western NC they have an excellent range, five times more than the GRMS radios that I have. Rob was excellent to deal with and answered all my questions. I would encourage anyone who is looking for short range communications s to consider Rob and the MURS radios. I will be trying the radios later on at my In-laws home because they live in the piedmont region …


Letter Re: Potential Range of Nuclear Weapon EMP?

Mr. Rawles: I’m confused. Some things that I’ve read say that the maximum range of [nuclear weapon electromagnetic pulse] EMP is about 60 miles, but others say 200 or 250 miles. Which of them is right? Wouldn’t a terrorist bomb at ground level have shorter range EMP than a nuke touched off at high altitude or low orbit? (With a wider horizon.) Thanks, – Lance in Nebraska JWR Replies: You aren’t the first SurvivalBlog reader to ask about the greatest potential effective range of an EMP-optimized nuclear detonation. I first discussed this in SurvivalBlog back in October of 2005. The …


Letter Re: Question on LEDs and EMP

Hi Jim: Your blog is the best I’ve come across on the Internet. Very useful information. Regarding the subject of [Electromagnetic Pulse] EMP, are the new Light Emitting Diode (LED) flashlights more, or less immune to EMP than those using conventional incandescent bulbs? Modern solid-state circuitry is in grave danger of terminal damage in the event of an EMP occurrence. LEDs are composed of a semiconductor junction, similar to transistors and integrated circuits. Do modern LED flashlights have enough of the right characteristics to pick up sufficient EMP burst energy and become permanently useless? Your comments please, and thank you. …


Letter Re: Advice on Where to Learn Practical, Tactical Skills

1

Dear Jim: As my confidence in the dollar depreciates and my desire for skills increases, I’m wanting to convert FRNs into hands-on knowledge. What weeknight or weekend workshops would you recommend? Are there any places where you can learn Army Ranger skills without joining the military? Animal husbandry, and so on? – Spencer JWR Replies: There is a tremendous wealth of free or low-cost classes available–enough to keep you busy every weekend of the year if you are willing to drive a distance. If you have time and just a bit of money, you can get some very well-rounded training …


Book Excerpt: Patriots: Surviving the Coming Collapse

SurvivalBlog reader L.C. recently asked me: “What’s your novel “Patriots” like? Is it like the Jerry Ahern [“The Survivalist”] books?” My novel “Patriots” is hard to describe. It is a fast-paced novel, but it is not at all like Jerry Ahern’s novels. I did my best to weave a lot of practical and tactical information into the storyline. To illustrate, here is an excerpt from one of the later chapters in the novel (titled “Radio Ranch”) that shows the style: Edgar Rhodes had just turned 72 when the Crunch hit. He had lost his wife two years earlier, to cancer. …


Letter Re: Free Shipping Special on MURS Radios

Hi Jim, I have been fortunate to acquire another batch of $49 MURS radios. In honor of Patriots Day and the wonderful support from your readers I am able to again offer them a special deal. With the purchase of two or more radios you will get free shipping. Please see this special ordering page for details. This offer will expire when supplies have been depleted so don’t delay. These radios are ideal for spring and summer outdoor activities as well as for use in “hard times” communications. Thanks! – Rob


Information and Communication Capabilities for Preparedness, by NC Bluedog

Dear JWR: My wife and I use a “thinking process” concerning preparedness that I would like to share with you and your readers, as well as expand upon one of the items. We organize our thoughts and actions along the line of tiers of necessity for survival. This is analogous to the oft-quoted “beans, bullets and band-aids” strategy. The first tier is absolutely critical for survival and consists of air, food, water, shelter and security. This not only includes physical items such as stored food and weapons for security but also knowledge such as gardening and tactical/strategic planning. The second …


Letter Re: Practical Information on EMP Protection for Home Electronics

Sir: Thank you for your hard work. I am not sure if this was covered here before and, in the case it has not, I wanted to supply the following information to help suppress fear regarding electromagnetic pulse (EMP) and specifically, its effects on communications equipment. I am tired of reading “seal the radio in a metal ammo can, place the ammo can in an old microwave and place the old microwave in an old refrigerator, which is then buried under 8 feet of earth,” et cetera. Here is the reference for a four-part article in Amateur Radio Relay League …
