Introduction In my recent SurvivalBlog multi-part article, Communications Options for the Common Man, I looked at how to use commonly available license-free radios in a way that provided a low level of communication security by following a few basic rules, by mostly untrained people. Included in that article was the use of field phones that are easy to use, and provide the highest level of communication security that could be available to both untrained and trained personnel. In this article, I will describe methods that could only be used by trained and disciplined personnel who can maintain higher standards, and …

(Continued from Part 1. This concludes the article.) I will devote the rest of this article to a USB “dongle” type radio receiver that I have on hand, and the amazing things you can do with it. I also intend to make mention of a device called a “Tiny SA” a signal analyzer that was made more for spectrum analyzing signals on the test bench but can also be used for SIGINT as well. The USB dongle I am currently using is the RTL2832U. This is a low-price unit costing just $40. But I do advise you consider buying the …

(Continued from Part 5. This concludes the article.) Field Phone Line Circuits: The Platoon Hot Loop This method can to be used if the layout of LP/OPs is favorable. This method of connecting phones is referred to as the Platoon Hot Loop, yet the connection can be made to string the phones together, not in a circle but all along a singe line be it straight or in a circular shape that resembles a perimeter. The ‘loop’ is actually the electrical path created the connections made in a series in the same way Christmas tree lights were once supplied with …

(Continued from Part 4.) The Swedish M37 field telephone is an example of a good middle-of-the-road approach that is relatively lightweight, affordable, adequately durable, and mostly found to be in good operational condition.  These are not as sophisticated and suitable for silent operation as either the TA-312 or the TA-1, yet they can be fitted with a 12 VDC grain of wheat sized red LED that pulses when an incoming call is made to the phone or a peizo buzzer that softly chirps and closely duplicates the TA-312 reduced volume ‘ringer’ merely by connect either to the terminals.  Disconnect the …

(Continued from Part 1.) I’ve busted other Ham buddies who were not FCC compliant with an embarrassing phone call.  It is a fun and a useful exercise and practice of a poor man’s version of what is referred to by the military as Signals Intelligence (SIGINT). Intelligence of any kind, from Human Intelligence (HUMINT) to SIGINT is needed, because intelligence gathering in general is essential to our security operation. Intelligence from all sources should drive our security operations.  I (and others) will be listening for radio traffic as that is the easiest form of intelligence available to the survivalist.  As …
