Letter Re: Observations on a Tour of a Telephone Company Central Office

Hi Jim, I just came back from a tour of one of our local phone company’s central office (CO) and this is what I learned: Besides finding out how our phone lines work, I found out that the hardware there runs on 48 volt DC power. There is a large battery bank in the basement and the batteries are charged by the grid. It is made up of large clear cylinders and you can see the acid level and the plates inside. In the case of the grid going down it has a generator back up. Many of these offices …


The Precepts of My Survivalist Philosophy

In the past week I’ve had three newcomers to SurvivalBlog.com write and ask me to summarize my world view. One of them asked: “I could spend days looking through [the] archives of your [many months of] blog posts. But there are hundreds of them. Can you tell me where you stand, in just a page? What distinguishes the “Rawlesian” philosophy from other [schools of] survivalist thought?” I’ll likely add a few items to this list as time goes on, but here is a general summary of my precepts: Modern Society is Increasingly Complex, Interdependent, and Fragile. With each passing year, …


The ABCs of WTSHTF, by Mark B.

The ABCs of When the Schumer Hits the Fan (WTSHTF.) aren’t what you have prepared, acquired or stowed but even more basic in the preparation processes that we sometimes take for granted. The A is the ability to learn, to adapt and to try. No matter how many classes we take or how much we have stored away there is the potential that we might have missed something or prepared for one scenario and ended up with another. We may be in the middle of TEOTWAWKI and not be fully ready but guess what, we aren’t scheduling it. Ability is …


Letter Re: Alternative News Sources When The Grid Goes Down

James In the early 1990s–before Internet was ubiquitous–I remember a well-connected VHF packet remailer network that was nearly on par with the old Fidonet dial up network. Unfortunately while many hams played with packet 15 years ago, the complex mailbox routing networks are now mostly replaced by the Internet. I don’t expect any data network resembling the Internet to evolve if the grid goes down. This is not to say that local networks using sound card data modems on CB or FRS radio or with Wi-Fi gear might not spring up, but it would be a low priority in both …


Letter Re: Surplus Ambulances as BOVs

Dear Mr. Rawles, Perhaps an overlooked, but wonderful option for a BOV is an ambulance. You can often find used ambulances on eBay or at [fleet dispersal] auctions. They often have fairly low miles, have been well maintained and are most often diesel. They come with lots of storage compartments and equipment built in, as well most have propane fuel systems, generators, inverters etc. There is usually at least one “bed” in them as well. The outside storage compartments are often ready to go for the prepper as they are often diamond plate on the interior and have webbing for …


Letter Re: Alternative News Sources When The Grid Goes Down

Sir, I have been hooked to your blog for weeks now and have a topic suggestion for you. The only news I can trust comes from independent blogs with communities of users working together to bring critical information to light. Web sites like The Housing Bubble Blog have saved me tens of thousands of dollars by being months ahead of the mainstream media (MSM) and by reporting honestly. With the internet we have the means to organize grassroots efforts to support candidates like Ron Paul. We can be kept up to date with the latest injustices and know when our …


The “Come as You Are” Collapse–Have the Right Tools and Skills

When the Second World War broke out in September, 1939, the United States had nearly two full years to ramp up military training and production before decisively confronting the Axis powers. In the late 1970s, looking at the recent experience of the 1973 Arab-Israeli War, the Pentagon’s strategic planners came to the realization that the next major war that the US military would wage would not be like the Second World War. There would not be the luxury of time to train and equip. They realized that we would have to fight with only what we had available on Day …


Letter Re: AA Cells and Mobile Power

There was a discussion about batteries a few days back on SurvivalBlog. The writer advocated using AA NiMH cells almost exclusively, with adapters for devices requiring C and D cells. While I do agree that this is a good approach for some devices, there is certainly some merit to having full size 10 Amp Hour (10,000 MAH) batteries in high [current] draw or long term use devices. Not only is capacity significantly higher on larger cells, but the maximum safe current draw is higher too. Good NiMH C cells have 2-to-3 times the capacity of AA cells, and NiMH D …


The Big Picture — Grid Up Versus Grid Down–Oil, Soil, and Water

Before selecting retreat locale, It is crucial that you decide on your own worst case scenario. A location that is well-suited to surviving a “slow-slide” grid up scenario (a la the deflationary depression of the 1930s) might not necessarily be well suited to a grid down situations. As stated in my post on August 15, 2005, a grid down situation will likely cause a sudden onset variation of TEOTWAWKI with a concomitant mass exodus from the big cities resulting in chaos on a scale heretofore never seen in modern memory. My own personal “best case” scenario is an economic depression, …


From the SurvivalBlog Archives: Start With a “List of Lists”

Start your retreat stocking effort by first composing a List of Lists, then draft prioritized lists for each subject, on separate sheets of paper. (Or in a spreadsheet if you are a techno-nerd like me. Just be sure to print out a hard copy for use when the power grid goes down!) It is important to tailor your lists to suit your particular geography, climate, and population density as well as your peculiar needs and likes/dislikes. Someone setting up a retreat in a coastal area is likely to have a far different list than someone living in the Rockies. As …


Letter Re: Gauging Interest in Dakota Alert MURS Radios

Hi Jim, I am looking to gauge interest from your readers for the Dakota Alert MURS Base and Handheld radios. If there is enough interest in a special group purchase, I can offer the M538-BS MURS base station for $69 (plus shipping) and the M538-HT MURS hand held for $74 (plus shipping). Interested readers can e-mail me if they would like to be part of this group buy. (see the MURS Radio web site.) Thanks! – Rob at Affordable Shortwaves


Letter Re: Constructing an Improvised CB Radio Antenna

Jim, Regarding the recent blog article “Constructing an Improvised CB Radio Antenna”, here is a site that has good construction info and a few graphical images of custom built CB antennas This site by Signal Engineering adds some antenna theory for those inclined to learn more about CB antennas. If you are into experimenting with antennas, I recommend getting an antenna analyzer from MFJ. They are fairly inexpensive (as far as test equipment go) yet will yield very helpful tuning and optimization information. You can purchase one for use in nearly any radio service (ham, CB, VHF/UHF. etc).- Rob at …


Constructing an Improvised CB Radio Antenna, by Dim Tim

I have put a great deal of the info I have gleaned from SurvivalBlog to good use in my own preps. To reciprocate, the following is one of hopefully many bits of survival information that I plan to pass along to all the readers, in the hope that it will help someone else. A short time back I read a few posts on some survival communications issues, and found them to be very helpful. They also got me to thinking about something that I did back around the start of the eighties, that I believe would be a great piece …


Sources for Free Survival and Preparedness Information on the Internet, by K.L. in Alaska

Recent comments in SurvivalBlog provided excellent advice on using the public library. You can gain lots of knowledge with no expense, then purchase only those books you want to keep on hand for personal reference. Also, many colleges and universities loan to local residents, so you can use them too, even if you aren’t a student. If your local libraries participate, a great resource is Worldcat. It lets you search for books from home, then go check them out, or get them through interlibrary loan. What will happen to the Internet when the SHTF? There’s no guarantee it will survive. …


Letter Re: Communications in Times of Crisis

Hi, Jim: As a licensed Ham and (ever since the 1970s) a licensed CBer (those were the days when CB licenses mattered.) I had to go quickly back and check the Communications in Times of Crisis posting one more time, and sure enough I did find a couple of small errors/omissions which need mention. First, the 12 watts output mentioned by the author for CB radios only applies when operating in SSB mode. If in AM mode, you are still limited to 4 watts out. Yes, I know some folks run “foot warmers” (illegal [linear] amplifiers); but, remember that those …
