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 …


Preparedness for Digital Doomsday, by David W.

One subject I’ve not seen mentioned recently is that of data recovery and security. As a proponent of various disaster recovery plans for large companies during my tenure as in information technology auditor I’d like to propose a few ideas to the readers to increase the chances of keeping data post-TEOTWAWKI. No one plan works for everyone and your mileage may vary. First off we all generate lots more data then we think. The most common insurance against loss of a home PC is regularly maintained backups to some form of storable media like DVD-r’s. However, in a post-TEOTWAWKI world …


Letter Re: Another COMSEC Warning on Social Networking Web Services

Jim, I worked in Network Security in both the military and civilian sectors for quite a few years. The thing I would recommend is not to use any social networking site. Due to the terrible security embedded in the new web programming technology they are rampant with malicious software that can be downloaded to your computer. Your computer would then be owned by some goon who would use it to attack others and steal your personal info, such as your bank account number, and so forth. But you say, hey I have the newest router, firewall and anti-virus. The companies …


Letter Re: Another COMSEC Warning on Social Networking Web Services

James, This is a communications security (COMSEC) warning: Readers may wish to think about the networking tools used to communicate between friends and associates – Facebook, Linked-In, Jaiku, Pownce, Yammer, and others – and realize that not only do they pose a serious threat to the security of their personal information, but some of them are now apparently being used to bring new people into the non-secure comms environment by falsifying “invitations” from others to join. While tools such as Outlook, AIM, Yahoo Messenger, Gmail, Hotmail, Flickr, and MySpace should also be used with caution to limit the damage that …


Letter Re: Securing Bedroom Doors Against Home Invaders

Dear Mr. Rawles, I will try to keep this short. Hopefully my question might come in handy for a number of your readers. First, thank you for your site and your publications. I am almost finished with “How to Survive the End of the World as We Know It” and am about 50 pages into your “Rawles Gets You Ready” family preparedness course. So far I am loving them both. I am reading quickly through them first and next my wife and I will study them thoroughly together, adapting the information and creating our “list of lists.” Now, I have …


Letter Re: Parabolic Dish Shoutcasting

Mr. Rawles, Regarding Skyrat’s and other SurvivalBlog.com readers that may be interested in obtaining large C-Band dishes for Shoutcasting, I have a potential free source: I work in the satellite industry and often receive calls requesting that decommissioned and obsolete C-Band dishes be removed from the roofs or ground mounts of hotels throughout the country. When the hotel management receives the estimated cost for the removal, more often than not, they reluctantly decline to have the eye-sores removed. Some enterprising readers may be able to negotiate a deal with a local hotel manager to remove a dish at no charge …


Letter Re: Parabolic Dish Shoutcasting

Mr. Rawles: I had thought I had seen mention of it on Survivalblog, but have been unable to find it. “It” is a commo system for line of sight communications, which could be employed between adjacent homesteads. The technique is to situate two dish type antennae, as in the “C” or “Ku” band (roughly 1.5-2 meter) earth station antennae used for rural satellite television reception, pointing at each other. With gain on the order of 30-35 dbi, they provide roughly 8 to 10 fold amplification of the signal inputted into it. Now, if I were to face the dish, pointing …


Letter Re: HF Radios and “Shoutcasting” Parabolic Dish Communications

Dish Communications Jim: [In response to an earlier letter,] a HF network is a good idea. A local network also has its merits. There are lots of methods and frequencies for local area usage. Some use military surplus equipment, some CBs, some ham, some TA-1 field phones with wire, some use Wireless Fidelity (Wi-Fi) access points (a great idea if you’ve planned ahead for electricity and it actually works.). Shoutcasting I know three people in Colorado who use old solid [metal-coated fiberglass or sheet metal–not expanded metal mesh ]satellite dishes to be able to stand on their hills and talk …


From David in Israel: Off Grid Alternatives to Utility-Supplied Electricity

James One of the most troubling things I see when speaking to people about going off grid is how badly they want to keep all of their electrical appliances and just spend many thousands of dollars on a battery bank more appropriate for a U-boat and solar cells or generators to keep them topped off. Having had a minor role in a micro-satellite system design proposal one thing you learn when confronted by limited power supply is to either economize or do without. The appliances you own for on grid use are not efficient. They are built to be inexpensive …


Two Letters Re: Maintaining OPSEC in a Geographically Extended Retreat Group

James, An idea for maintaining security: One could setup and run their own IP telephone server and use encrypted IP phones to communicate amongst their group. Asterisk is an example of an open source telephony server that runs on Linux. The server must be connected to the internet and has to be made specifically aware of the particular encrypted phones that the group uses. The phones must also have Internet connections. The entire comm channel is encrypted. If the server can be kept secure, then I think there is no point in the channel that is subject to monitoring. If …


Letter Re: Maintaining OPSEC in a Geographically Extended Retreat Group

My Dear Brother in Christ, Before I get to my question my wife and I would like to express our sympathy (a overused word I now but heart felt) at the loss of your partner and our sister in Christ. I know there is joy to be had for her being with Jesus but the loss is still felt by you and your kids and our prayers are with you. Now my main question. Do you have any ideas regarding security with it comes to putting a group together where the potential members are separated to the extent that it …


Letter Re: Retreat Commo and Monitoring Suggestions from a Ham Operator

Mr. Rawles, I would like to hopefully answer some questions on retreat communications.  I have been a ham radio operator since I was 11 and am the third generation of hams in my family.  I was recently asked by multiple people to help them come up with a list of equipment that they could buy to have decent communications in there planning.  These people are not hams and don’t know much about radios.  After giving it some thought I have come up with a list of things that can be purchased on today’s market that should cover basic communications needs.  …


Letter Re: Using Direction Finding on Looter Bands

Dear Mr Rawles, I’ve just finished reading your latest book [“How to Survive the End of the World as We Know It: Tactics, Techniques, and Technologies for Uncertain Times”], and let me begin by thanking you for writing it. I have just one small quibble in Chapter 9, Communications and Monitoring. This is something we both missed, and it didn’t occur to me until after reading this chapter. While I agree with you that looters are unlikely to have the inclination, hardware, and talent to do direction finding (DF) on a retreat’s radio transmissions, the reverse is not necessarily true. …
