Letter Re: Critical Capabilities for Retreat Defense: “Move, Shoot, and Communicate”

Dear James, A couple of things to ponder: IR Cyalume sticks are costly and have a limited shelf life. High intensity IR LEDs can be easily built into an “intrusion illumination” system that can be actuated by a number of means (trip wire, seismic, passive motion detection, command, etc.) LEDs are cheap and a simple, reusable, battery powered unit with indefinite shelf life can be cobbled together for a few dollars. Visible and IR LEDs can be made into lights for a variety of uses including illumination and signaling. See: http://www.trailquest.net/TQaltgear.html#LED Years ago, I had an odd dream. I dreamt …


Letter Re: Zenith “Trans-Oceanic” EMP-Proof Shortwave Radios

Jim: I just realized something that some of the SurvivalBlog readers might find interesting: All the older Zenith Trans-Oceanic radios have replaceable (“socketed’) transistors. The Zenith Trans-Oceanic radios model 1000 and 3000 all have Sockets. I recently replaced a PNP transistor in a 1962 Sony with a new 2N3906 and the radio worked! So, if someone buys one of these older multi-band shortwave radios with the transistor sockets, then they should buy a bunch of cross-referenced transistors and place them in a small metal can to protect them from EMP.  See: http://www.transoceanic.nostalgiaair.org/3000.htm Open the PDF file and you’ll see the …


Rourke on: Establishing a Survivalist E-Mail/Cellular/Wireless PDA Alert System

How can you best avoid being caught in the egress gridlock of sheeple? The best answer to that problem is having the critical information first, allowing you to bug out prior to everyone else. If you are ready to go, or ready to do what you need to do, a few hours or even minutes may be all the edge you need. The information age is becoming the instant information age, but the problem becomes filtering out what you don’t want (too much information, then again you can just watch major media and let them filter out what they don’t …


Critical Capabilities for Retreat Defense: “Move, Shoot, and Communicate”

As an Army officer, I learned that in order to be effective, and army must have three key abilities: To move, shoot, and communicate. Take away any one, and you are ineffective. But if you get all three right, and you can absolutely devastate an opponent–even one that has superior numbers. The same principles apply to defending a survival retreat in a TEOTWAWKI situation. In the context of a static retreat position, movement is not as crucial, but don’t overlook the need to conduct commerce, and even the need to move between retreat buildings safely. And in an absolute worst …

On Expedient Shelter/Greenhouses:  You are right the human waste was to be baked and re-cultured before being introduced into the system guess most of us don’t have a small reactor to provide the unlimited heat/radiation as a Mars  expedition would have. I think there are enough collective brains amongst SurvivalBlog readers to design a concept pop-up settlement for vehicular bugout or being forced from your primary retreat. On Mobile Ham Gear: The ADSP2 is a good unit (only DSP unit I have used please suggest better) if you can find them at a radio shop, on sale they go as …


Letter Re: Expedient Field Telephones and Lightweight HF Transceivers

Mr. Rawles, I have been reading your blog for a few weeks now and I noticed that many references are made using the surplus TA-1 telephone. A household telephone can be used for a point-to point two-way communications by using 4 wire cable, a 9 volt battery (better 12 volts) a 300 ohm resistor, two momentary switches and two signal devices such as a piezzo device or buzzer. A 9 volt battery will furnish telephone comm. for several miles but have never used one over two miles. I am also a Amateur Radio Operator, (57 years) and if you must …


Two Letters Re: David in Israel on Mobile Multi-Mode Survival Communications

Jim: I would just like to point to a very nice (if somewhat costly) piece of radio equipment, The Buddipole from: http://www.buddipole.com/  It is an extremely flexible antennae system, which gives you coverage from the 40 meter band through the 2 meters – it is possible to tinker with a lot of different setups and it has a proven track record and is currently in use with your Special Forces teams as well as numerous hams. Budd Drummond who runs the company also has a very good customer service and is a great person to discuss antenna needs with. (Just …

Letter from Mark G. Re: The Army Aviator on HF Radios

Howdy Mr. Rawles, I have been reading your blog for the last week or two, and I also read your book [Patriots] last week (lots of good info, thanks!) I have a question regarding the post referenced in the subject line: Are the GRC-215 radios available surplus, or is there something similar available on the commercial market? Since I have been following your thoughts I have become more interested in communications (never thought too much about post-SHTF comm before), and I would like to eventually get something similar, although a SSB capable CB will probably come first, and I will …


Letter Re: More on Survival Communications and Six Meter Propagation Oddities

Howdy Mr. Rawles! One frequency [band] that I have had good results from has been 6 meters. This frequency is really unique. It may not be suitable for every situation, however its properties can be of use. It has the ability to become a national frequency when the E layer of the atmosphere is active. I have talked to HAMs from Washington state, to San Francisco, California down through Texas, the Cayman Islands, the Turks and Caicos Islands, Haiti, parts of South America, Vermont and above the Arctic Circle in Canada, [and] among adjacent states. Lets just say I am …


Letter Re: Amateur Radio in Survival Planning

Jim, I wanted to add that I think it is a great time now to test for Amateur radio license (“Ham” radio.) The entry level test is apparently quite simple and there is no longer any requirement for morse code (although that is a good skill to acquire.) [JWR adds: IIRC, that applies only to “No Code” license classifications, which have band restrictions.] I have been routinely listening to 75 meters at night, here in Coeur d’Alene {Idaho.] I here people as far as San Diego, California. Those broadcasting within 800 miles (Nevada, Oregon and all over the northwest) come …


From David in Israel Re: HF Radio Propagation and Improvised Antennas

Here is a good military level primer on HF radio propagation with some links on how to make improvised antennas. See: http://www.globalsecurity.org/military/library/policy/army/fm/7-93/Appd.htm For more fun, try Googling on the search phrase: “stealth, apartment, and wire antennas.”  There is an amazing science behind these home-built wonders.


Two Letters Re: A Dedicated SurvivalBlog Amateur Radio Net?

Jim: A good frequency for two-way radio communications is the little-used [amateur] FM radio band on 220 MHz. (See: http://wireless.fcc.gov/220MHz/)  Very few scanners cover it–only the most expensive scanners do which most people won’t buy. The reason scanners don’t cover 200 – 300 MHz is because its [mainly] used by the military. For example, the control tower at Moffett Field Naval Air Station is on 301.something MHz. In my research, I noticed that there are only two repeaters in Idaho that are on 220 and they are both in Boise. Outside of the big cities 220 is hardly used.  One …


From David In Israel: A Dedicated SurvivalBlog Amateur Radio Net?

James: It might be worthwhile to have a dedicated SurvivalBlog radio network. We could set up something on several HF bands. I am thinking it would be nice to have a way for SurvivalBlog readers to contact one another, even if and when the Internet and/or the phone system goes down. I think that there may be some interesting news will be coming from here [in Israel].  OBTW, the new year is 5766 from the creation of the world, the world is being closely judged for the next few days as Hashem re-coronates himself as the true King over kings. …


Letter Re: Inexpensive HF Transceiver?

Could you give me some advice/direction on purchasing a HF Transceiver for use in emergency communications events. Money is limited (like when is it not) but I want something that is a good all around investment. Most bang for the buck so to speak. I have background in radio/tv. Thank you so much! JWR’s Reply: Your best bet is a probably a “pre-digital” vintage rig from the 1970s–perhaps a Kenwood. Just make sure that it is set up to run on 12 VDC so that you can use a vehicular mount or run it from a retreat solar power/battery bank …
