Sometimes old tech is the solution to your prepping problems. We know that all modernized militaries and governments have the means of homing in on a radio signal broadcasting location, regardless of incription or frequency hopping capabilities. So an old fashioned hard wire system might be the answer to setting up an undetectable LP/OP (listening […]
Dipole Antenna
So I have to admit I don’t have my HF/HAM radio yet, but it’s on my Christmas list. I have my eyes set on a radio a little more powerful than a handheld HF; so we’ll see what my wife says. However, I do have my dipole antenna ready to go (a little backwards, I […]
HF Band Segments
A friend of mine with great HF radio experience shared this info with me after helping him construct a vehicle mounted dipole antenna. The following is a breakdown of the HF band with a general description of the behavior of each segment. 2 thru 5 MHz: This band is useful during daylight hours for intermediate […]
Ham Radio Terms
I have a great interest in ham radios that has been a recent result of talking to friends and family; and I look forward to delving deeper into this communications world as soon as I can siphon the money out of my wife’s grasp. This can, but doesn’t have to be a huge hit on […]
Hand and Arm Signals
Hand and Arm signals are one of the most common forms of communication used by United States Army soldiers or group of soldiers when a radio silence is in effect or if the soldiers need to remain undetected. Hand and Arm signals also become useful in situations of overwhelming sound such as a vehicle motor […]
Morse Code
The other night my brother in law and I were sitting downstairs playing borderlands 2, or something like that, when we heard a long stream of “dits” and “dahs” manifest itself. Being quite curious as to who was using the code up stairs I went up to find my wife on the phone texting a […]
Signal Rescue Aircraft
Pulled these out of the FM 21-60 Chapter 5: Signals to Aircraft. These are internationally recognized signals that can be used with both fixed and rotary wing aircraft (planes and helicopters). Print these out and learn them if you have a few; the most likely symbol you will use in the civilian world will be […]
Rescue Mirror
There are different methods of accomplishing this; but this is what I learned back in wilderness survival in scouts. Any mirror works and it is nice to have one designated specifically for this purpose. My emergency mirror is a small pocket mirror. In the center of this I scratched a small hole in the reflective […]
