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 …

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 …

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.  …

James, I was glad that a reader mentioned the Hallicrafters S-38 series of radios. I had forgotten to mention that the All American Five (AA5) type of radio was also sold in a multi-iband version by Hallicrafters. These are still often available for under $100 in working condition. I have a Hallicrafters model 5R10A, which is a lot like a [Hallicrafters] S-38D. It’s an AC/DC design like the AA5 radio that can be run on nine or ten car batteries wired in series with no inverter. (In a test, I found that nine fully-charged “12-volt” batteries wired in series provide …

James Wesley, A Zenith Trans-Oceanic (T-O) is hard to beat, especially if you could snag a [rare] R-520 militarized version. This has a spare tube rack, uses no wax paper capacitors, is fungi proof, et cetera. The T-O definitely the world’s greatest portable radio (this side of the AN/GRR-6!) the G & H 500s and the 600 series as well as the R-520 all used the 1L6 converter tube which has become expensive and just about un-obtainable. You can clip a pin out of a 1R5 as a substitute but shortwave performance usually conks out around 7-8 MC. The earlier …

Mr. Rawles; I have been monitoring the latest posts on vintage radios–pro and con–and decided to offer more information and a possible solution for SurvivalBlog readers considering vintage electronics. M.E. is spot on in his post about the relatively anemic performance of crystal radios versus superheterodyne (as all “American Fiver” sets are known) tube radios. The biggest issue with crystal sets is their absolute lack of range. During a severe crisis, local radio stations will most likely be forced to regurgitate propaganda resulting in little, if any, useful information. As is generally known, news from afar (Canada, Australia, Europe, etc) …

JWR, While the concept and idea of a Crystal Radio for TEOTWAWKI (no battery or external power) sounds ideal, in practice the execution leaves much to be desired. Many ignore the fact that if a grid down situation occurs (or worse an EMP attack) that most radio stations in the affected area will be down and out for the count. In a best case scenario if the transmitting station’s components aren’t damaged, how long will their source of backup power stay up? Many modern stations rely on satellite feeds or long line telephone circuits for their program materials to be …

Mr. Rawles, Thank you for including the recent article on amateur radio in SurvivalBlog. I have been an amateur radio operator for about 35 years and have been playing with radios for over 40 years. I am amazed with the depth of knowledge of the readers on your blog. In many of the topics covered, I know very little. I have one criticism of amateur radio operators concerning “emcon” or emergency communications. Many hams like to participate in the organized drills with their local Emergency Government officials. This is a big mistake in a SHTF scenario. Think of yourselves, your …

Jim, Something I’ve often wondered about prepping, but have never seen addressed is the use of Crystal Radio sets for after TEOTWAWKI. Small, portable, and they don’t require any electric source. There are some high performance sets out there that get not only AM [broadcast band 560-1700 KHz], but also shortwave. I’d love to have some input from a knowledgeable individual as to the “best” unit from a prepping standpoint. The variety and cost spans the spectrum from under $10 at Radio Shack, to antique reproductions for over $500. Confusing to a novice, to say the least. But the technology …

In the modern world, there are few things as critical as the propagation of information. Anytime, day or night, we have access to news, weather, and interpersonal communications. When that information is unavailable whether due to a misplaced cell phone, internet disruption, or other factor, we begin to panic, feeling cut off and isolated. When disaster strikes, up to date information could be as vital to your survival as food, shelter, or a means to defend yourself. We can all make plans for our retreat and relocation, but without a means of contacting one another when the time comes, all …
