Letter Re: The S-250 Vehicle Shelter

Letter Re: The S-250 Vehicle Shelter Dear Editor: Now available from your local Federal Government through GovLiquidation.com is what is commonly known as the S-250 shelter. In essence, this is a highly sought after, well constructed, insulated truck shelter used by the military as a radio shack or electronics shelter.  [They were designed to be mounted in pickup beds, but more recently have been mounted on Humvees.] When looking online you’ll find most of those seeking these shelters at auction are either military vehicle collectors or those seeking a super heavy duty slide in truck camper.  Thirdly you’ll find some …


Letter Re: Passport to Worldband–2009 Will be the Last Edition

James: A heads-up for your readers: It has been announced that the 2009 edition of the book Passport to World Band Radio will be the last. I just bought one from the company that published it. They’re still in stock and significantly less expensive than the storefronts who still carry it at Amazon. – Del JWR Replies: Thanks for sending that news. That is disappointing, since the book is a great reference, especially the broadcast schedules. The frequency charts are bit less perishable, but I’ll be sad to miss out on the updates. I’m confident the on-line references will fill …


A Personal Journey in Preparedness, by Mountain Man

I’m fairly new to SurvivalBlog but now it’s an every day read. I wanted to write and share my own journey of preparedness with you and your readers. After living with three and a half million people for about 22 years, a move to the country was long over due. I made the decision to get out of the city back in 1999, when I starting to take things a bit more seriously with all of the talk about Y2K. I was really hoping that something would have happened back then so I could test my skills at being prepared …

Please ensure that you are familiar with any related laws before attempting any of the methods outlined below. They are therefore provided for information only: With regard to the recent article on semi-anonymous Internet access and the use of wi-fi, by Jeff T: I agree with many of the suggestions in this article, but also wanted to expand on these and identify a number of possible additional risks associated with using wi-fi connectivity. Ben from Tennessee is quite …


Letter Re: Semi-Anonymous Internet Access

Dear Editor: Is using a laptop with wi-fi from the library etc any better (in terms of OPSEC) than having a home Internet connection? We disconnected from our satellite ISP from home a while ago and now only go online from assorted wi-fi connections when we get to town. But is this any safer? What else should I be doing to keep a lower profile? Thanks, – Jeff T. #1 Son Replies: There are several ways that you can be identified over the Internet. First is though your IP address, and more significantly, through your Internet service provider (ISP). Information …


Letter Re: Infoworld’s Take on IT Doomsday Scenarios

James, The magazine Infoworld is a fairly trusted source in the information technology (IT) field. They recently posted an article titled, “Tech apocalypse: Five doomsday scenarios for IT”. Here is a quote: “What could happen [from a wide scale EMP attack]: Workstations? Dead. Data centers? Gone. Cell phones might still work, but the cell towers probably won’t, rendering them useless. Your car won’t start. A large enough attack will also shut down automated controls at power substations, leaving everyone in the dark. Think pre-industrial revolution days. In our scenario the New York Stock Exchange shuts down, causing shock waves to …


Letter Re: Some Notes About SCADA Software

James The pastor/programmer is somewhat correct about SCADA and Programmable Logic Controllers (PLCs), and his resistance of Windows based and “soft logic” is admirable. However, many SCADA systems installed out there recently have been implemented just as their name implies “SUPERVISORY CONTROL and Data Acquisition” in order to save labor costs by minimizing operator and maintenance training requirements on multiple different in- plant control systems. Most major power, refining, waste treatment systems etc. in recent years have utilized a DCS (distributed control system) as a SCADA base for overall and/or supervisory control often also monitoring or commanding smaller PLC systems …


Letter Re: Some Notes on SCADA Software

James: I have been reading SurvivalBlog for some time and have read your novel “Patriots“ and now reading “How to Survive the End of the World as We Know It”. Great job and love your work. I work as a SCADA programmer for water, waste water and power plants and was wondering if you had some background on this. I know you are somewhat hard on the system as an overall and it is well aimed. Most of the programs and programmer I am around take much care as possible to keep the Windows based computer as a window into …


Letter Re: Radio Communications for Retreat Intelligence Gathering

James Wesley: Ron Y.’s article posted on Sunday is interesting and helpful to those who don’t spend much time around radios other than, perhaps, their favorite music station. For those of us who have had a lifetime of radio listening and, in my case, work with public service units in times of disasters small and bigger, there are a few things I’d add. First is the scanner section of Ron’s information. My work desk has four scanners going at all hours that I am awake. Any one of them might flag something that is of interest or warrants tracking. Frequencies …


Incremental Preparedness: The Good, Better, Best Approach, by Jeff B.

For many, the idea of preparedness seems like an impossible undertaking. The amount of equipment and supplies needed is staggering. When I first came to the realization that I was under prepared, the gap between what I had and where I needed to be was too much for my public servant’s paycheck to bear. I would spend a lot of time discussing preparedness with a group that I would go shooting with, and all of these meetings would always gravitate to “which weapon do you plan for X meters?” or “how many rounds do you think I need for X …


Letter Re: How I Made My iPhone a Useful Survival Reference

Mr. Rawles: I loved the letter on the iphone. In addition to what LC listed there are also ballistics calculators for the math-challenged like me. (iStrelok is free and works pretty well). One caveat to consider with the mighty smart phone is the fact that it could potentially be used to locate your location and perhaps even as a bug to listen in on conversations. One work-around is to buy an iPod Touch. You loose the phone and GPS features, but you can still carry God’s word and all your multimedia in your pocket! Thanks again for all you do …


Letter Re: How I Made My iPhone a Useful Survival Reference

James, I depend on your invaluable books and Blog daily. I wanted to share with you and your readers my Archives Library system for when SHTF. I have an iPhone 3Gs ( and a spare one ). I feel that this is a more readily accessible and portable device as compared to a Kindle. I have loaded with many useful applications (“apps”) for survival and references. The main apps are : Carpenters Helper Photo Album and iTunes (for family viewing of pictures and my DVD collection DVDs ripped at 700Kbps VBR 2 pass h.264 is pretty good and saves on …


Preparing Your Church Congregation, by JSX in Virginia

My preparedness background started as a youth.  My father took us camping often and had an amazing gun collection; I’ve been able to teach my kids what he taught me – great memories both then and now!  In the 1970s, my mom and step-dad bought a little 2-acre farm in the middle of nowhere.  We kept a dozen or so chickens, had a few garden spots (that seemed to grow and multiply with each new season), homemade soap, homemade root beer (an acquired taste!) a “sewing room”, a small orchard, solar heating, our own 250-gallon fuel tank, and a year …


Letter Re: The Importance of Testing “Dead” Batteries Before Recycling Them

James- I wanted to share a money saving tip that applies to inexpensively preparing for TEOTWAWKI. With so many digital devices depending on batteries these days, most of us are conditioned so that, when a device like a digital camera or other smart gadget tells us the AA or AAA batteries need replacing, we simply toss out the “dead” ones and put in fresh batteries. But are the batteries really dead? Usually, not all of them are. I have a handy little Canon digital camera that we use around the house for insurance documentation, family photo opportunities at parties, pictures …


Four Letters Re: Preparedness for Digital Doomsday

Hello Mr. Rawles, The article by David W. on data storage raised excellent points, and is sure to get people thinking about an often-overlooked subject.. For the prepper on a budget, there are a number of avenues to secure your data that won’t break the bank. While it may be impractical to have several NEW laptops in your stash of supplies, there are plenty of good, used laptops available that will fit the bill nicely. You don’t need a powerhouse just to read your survival documents, and having one or more spares means fewer eggs in one basket. I’ll focus …
