Keeping Your Communications Private, by F.J.B.

In this age of continuing disregard for an individual’s privacy, it can be difficult to keep your communications private. Warrant-less phone taps, postal service mail tracking, RF scanners,  and random roadside searches will appear fairly tame once the strip-searches start at the mall. Of course, this is their goal but even non-government snoopers are out there scanning your ID, listening to your phone calls, and trying to hack into your email. Going somewhere? Who knows your schedule? Did someone overhear your plans? How can you know? What has happened to our right to privacy? Many people today are so beaten …


Dressing for Self Defense, by A.Y.

This is a review of considerations for civilian dress for basic self defense in most areas. Be advised some of these suggestions may be illegal where you live, follow all laws when dressing defensively. The goal of this article is to re-think basic aspects of normal street clothes and minimize any possible negative aspects of normal street clothes for purposes of self defense. An important consideration to this task is understanding your own personal Threat Matrix.  A Threat Matrix is the likely risks you personally have to face in your day to day life.  Are you an ordinary citizen in …


Letter Re: Listening in to the Joplin Tornado — and Other Disasters

Jim — Thanks for all that you do and the many able contributors to your site.  This evening, Sunday, 05/22/2011, I am listening to the “live audio feed” of the Jasper County and Joplin, Missouri, law enforcement scanner traffic.  As I am listening, the various agencies are dealing with the aftermath of a deadly tornado that hit Joplin.  As a former police officer I have been through this sort of event. However, listening to their radio traffic is eye-opening, even for me.  I am getting a new perspective on many of the nuances of dealing with a catastrophe of this …


Letter Re: Warning of Massive Solar Flares?

Jim: After reading several articles on EMP in the form of a CME/solar flare, my understanding is that we would have hours or even days in which to prepare for such an event. Although I imagine that a massive CME would still cause damage to our electrical grid, I would also think that many homes could be disconnected from the grid and electrical equipment shielded in metal containers before the CME reached us. Any thoughts? JWR Replies: Yes, there will be 12+ hours of warning, but do not depend entirely on the mass media. At times, they seem clueless about space …


A Real World Test of My Preparations, by Daisy in Canada

Last week my city was taken by surprise by a terrible windstorm.  There were some weather warnings but nothing prepared residents for what would come.  Winds reached 110 km per hour and the damage to property was extensive.  Several people lost their lives due to flying debris and downed power lines.  While some were without power for only a couple of hours, others were without for up to a week.  Although we got our power back after 48 hours, we still suffered sporadic outages for two more days. It was with a completely different attitude that I met this storm.  …


Two Letters Re: Using Your Smart Phone as a Survival Phone

James; When the cell phone network is down, telephones expend energy constantly searching for a connection. This can increase your battery drain. If you are in a situation where you know the network is not functioning, I recommend you set your smart phone to “Airplane Mode”. This disables all radio communication functions of your phone and allows it to act as a hand held computer thus no longer wasting power trying to contact a network that is not functioning. – Mike in Kentucky   Dear Jim: Being a techie/having worked in a cell store, I enjoyed Kelly’s article. What I …


Using Your Smart Phone as a Survival Phone, by Kelly H.

When preparing for any large-scale emergency or disaster scenario our initial tendency is to seek out the most basic necessities for survival: food, water, shelter. Those serious about survival expand these necessities to include protection, first-aid, mobility, etc. I believe one of the most important tools to include in any survival plan is a smart phone capable of offline card storage.   In my profession, I am attached to my smart phone. I depend upon it to work as much as my Leatherman while backpacking. I also know that during a large-scale emergency or a TEOTWAWKI scenario, a cell phone …


Letter Re: RC Aircraft Possibilities

James Wesley: I fly radio-controlled (RC) aircraft, and the Switchblade is a definite possibility. As you can tell from the video, there is a lot of computer generated “help” going on there, but the concept is solid, the technology to do this is already readily available and has been for some time. It’s just a matter of time until somebody completes the package. The problem is, for an aircraft that small, the maximum payload I could see might be around a pound, maybe slightly less. But a pound of C-4 could put a distinct “dent” in your day! Lately, the …


Prepare While You Can, by W.L.

Many of our family and friends have teased us about my husband’s and my desire to live as independently and as far away from others as we possibly can. They have often scoffed at our (as one relative called it) “end of the world pantry”. These are of course the same family and friends that love to vacation at our place. The very same that called immediately after 9/11 and asked if the violence and terror reached near their homes could they come and stay with us. These same people have begun calling in the days since the massive earthquake …


The Power of Three, by Jerry S.

Since we have all been reminded of the principle the “two is one and one is none”, it brings me to the conclusion that being prepared is really about “having a backup for your backup”.  So if “two is one”, then “three must be two”.  That has led me on a quest to discover at a minimum, three different ways to approach the problems we’ll face in a disaster situation.  If you are new to prepping or just want a different perspective of looking at things, maybe this will help.  To get us started, the first thing you should be …


Letter Re: A Review of Inmarsat’s IsatPhone Pro

Jim, I recently bought an Inmarsat IsatPhone Pro satellite telephone. I had set some requirements for a satellite phone (“satphone”) , including true worldwide operation, good reliability, and reasonable price, and the IsatPhone Pro (introduced in 2010) was not just the best deal, but the only phone that met all my my requirements. I shopped around for a few months and eventually bought the IsatPhone Pro Emergency Kit from GMPCS, a Florida-based retailer. This kit is priced at $821. It includes the phone (normally around $600 from online sellers), one year of “Emergency” service priced at $150/year with 60 minutes of airtime, …


Letter Re: Battery Options for LEDs and Small Electronics

Jim, I have read and enjoyed both your books. I have told all my like minded friends about them. Regarding LED flashlight batteries: I have a flashlight from Sportsman’s Guide that uses two of the CR123 batteries, it will also use the #18650 lithium ion battery. One of these takes the place of two of the CR123 batteries, and last much longer, and is rechargeable. The charger can use either 120 VAC or 12 VDC input voltages. I have a system set up that uses the Harbor Freight 45 watt solar panels. I bought mine on sale for $149 and …


Letter Re: Understanding Digital Ham Radio Modes

Dear Editor: Some SurvivalBlog readers are really into ham radio; some are not. I think you’ll all find this YouTube video link very interesting as it concerns various modes of digital radio transmissions that ham radio operators use daily and enjoy. It shows you, and lets you hear, what a digital mode is like if you come across it on your shortwave receivers, or your ham transceivers. There are advantages in recognizing that what you’re hearing is a digital message, and knowing the type of transmission. If you have a shortwave receiver that can discriminate the frequencies you can even …


The Backup Plan to a Backup Plan for Telecommuters, by Tamara W.

Assumption: “If it snows or storms, I can work from home and telecommute.”  Assumptions are not always correct. The major ice storms at the end of January and start of February 2011 prompted creating this plan for my husband and myself. (Or first backup plan was alternate transportation routes.) Lessons learned day by day: Day 1 When power goes out at the house, such as during the first day of the storm for about 6 hours, the only way you can work from home is by using precious generator  fuel or laptop batteries. Due to my husband’s higher pay rate, …


Letter Re: Low Cost EMP Protection for Electronic Gear

Jim, While working on my preps I found electrical specifications in the data sheet for the mylar-foil bags I was investigating for my food storage.  This reminded me that many computer components (e.g., motherboards, hard disk drives, and expansion cards) are packaged in mylar-foil bags for ESD protection.  I reasoned that since the ESD protection is provided by the conductive foil layer in the bag one should be able to use the same mylar-foil bags as Faraday cages to protect electronic devices and components from EMP. One of the perks of my engineering career at defense contractor is that I …
