Master Handbook Ham Radio Circuits

Imagine with me that for the duration of one night in the not too distant future the unimaginable happens, a flash of light lit the sky and you wake up to see what has gone wrong. You check yourself all over and don’t have any averse affects, but you observe quickly that lights don’t turn on, so you check your phone and it’s out too. How with regards to the cell phone? Nope, doesn’t work and neither does your TV. You try your car radio, but it is dead and your car, strangely doesn’t even start! Now panic is starting to flood your mind! You flush your toilet, but no new water runs in! You talk to your neighbors, but no-one seems to recognise what has happened! What now? An electromagnetic pulse or EMP bomb was exploded but not anyone knows it! Pandemonium breaks out! This kind of attack is in itself non-lethal to persons but highly detrimental to all electronic equipment. Transistors and circuit boards have been fried! Ranging from low level attacks that could disable instrumentation over a half to three mile radius to ones that could knock out all electronic systems and even the electricity grid over the whole country, this weapon provides both factor of surprise and devastation. Even altho these weapons may not yield any direct hurt to humans, consider the possibleness that all airplanes lose control and power instantly! Cars would stop working, traffic signals not even blinking, TVs black, hospitals would go dark, water deliverance schemes stop, trains stop or crash, farms stop producing, and everything relying on electricity and unprotected would without any delay die. The nation would be totally brought to it is knees and life would without any delay revert to horse and buggy days. Communication schemes down and circuitry fried, persons would be totally cut off from each other and survival would depend upon a person’s capacity to re-establish life without elements we depend on today. Can you imagine the effect of such a bomb attack on the psychology of a persons who have lived their whole lives without taking into account their dependence on the electric grid, the natural gas and water schemes that operate in their home. Just think of each household appliance and how dependent you are on it. No coffee pot, no dishwasher, no clothes washer or dryer, no vacuum or even an electric toothbrush. Few of us even store candles! Interestingly, old technologies, such as vacuum tube devices, stand a better chance to survive such a pulse. Storage batteries would not be affected. Flashlights might still work and concede for you to send flashing light Morse code over line of sight for the duration of night hours. If you are a ham radio operator or just a radio buff, you might consider fabricating a “Faraday Case!” It is a huge case made of ΒΌ” steel and lined with a copper grid. It will have to be grounded with big wire to a cold water line. This case ought to store a little 12 volt transceiver, a Morse code key, and solar cells competent of keeping your 12 Volt car battery charged. Your dipole antenna must survive, but store extra wire and coax just in case. All this could effortlessly be contained in a little retired refrigerator. Although this idea has not been tested, we believe an old refrigerator with an extra lining of steel and copper screening inside and all grounded would serve utterly and be huge sufficient and cheap sufficient to do the job. After the EMP bomb, assemble your rig then go on the air and check to see how spacious the harm is. Who knows, you might be the only connection to the world remaining in your area. Your lifeline may prove to be important to the survival of your family and that of your community. Like the Boy Scouts say, “Be Prepared!” |
