Faraday Shields for Preppers

FARADAY  SHIELDS

By Charles Henry

Everybody throws around the term “Faraday shields” or Faraday cages, but let’s be specific about what it is and how it is a must item for preppers.

Named after an expert in electricity, Mr. Faraday, the Faraday shield is a highly important item that is easy to build and vital for the protection of your delicate electronic equipment like radios.

Modern electronics, like a walkie talkie or the ignition system in your new car,* operate at very low voltages inside the box of circuits.  The electronic parts inside, like chips or integrated circuits, can not survive large electrical pulses—conditions as simple as high static electricity and as complex as strong electric fields and especially EMP pulses like that from an atomic explosion or CME radiation from a storm on the Sun.  Delicate electronics, and that means everything today, must be protected from strong electric fields.  One exposure to a big discharge or pulse, and POOF your extensive collection of radios are turned into junk.

Whatever item you have that has delicate low-voltage parts inside—radios, cel telephones, bugs and bug sniffers, televisions, video and digital cameras, and computers and the like—must be protected.  Dangerous pulses travel through the air like radio waves, are invisible, and not detectable in advance.  You will not feel them.  You can not reliably guess when pulses may come;  they travel near the speed of light and provide no advance warning.  Thus, you must store your electronic items inside a Faraday shield.**

A Faraday shield can easily be made by you at home.  The goal is to make a box of metal that completely encloses all the delicate items you have.  A simple example is to build a frame of wood or metal, say a two foot cube, and wrap that frame totally in copper window screen, the copper kind of screen that keeps flies out of your home windows.  Include an opening lid.  Tightly nail or clamp all joints so there are no gaps in the screen.  Be sure the lid closes and makes tight contact around its edges with the screen around it.  Attach a AWG 16 copper wire tightly to the screen to create a ground wire (long enough to attach to a ground rod).

The result you want is to have the screen block incoming pulse.  You put your electronics inside the shield and leave them there.  You may use a small wire to penetrate the shield to use to charge up the batteries while in the shield cage, but making any opening must be very small and sealing around it is necessary.   The shield can be stored anywhere dry.

Test your Faraday shield by putting a walkie talkie inside the shield with it on receive.  That is, the walkie talkie should be making background noise.  Nearby, transmit with another walkie talkie to see if the one in the shield receives the signal.  If the radio inside the shield hears nothing, your Faraday cage is done.  You can also use a portable AM radio, tuned to a station.  If the AM radio stops playing when inside, then the shield is ok.  The grounding of the cage is an added step sometimes not necessary but a precaution.

Some preppers will use a new metal garbage can as a Faraday shield.  That should work good if the lid makes total electrical contact with the can all around the edges.  The point is to enclose the electronics completely with metal.

You could wrap individual items in metal, like the copper screen but not thin foil, but because the item must be totally covered, it will not function.  A prepper may think he could wrap the body of his walkie talkie, but with the antenna sticking out, the radio will be killed by the kinds of pulse we are talking about.

Old tube-style radios and very old cars or trucks are less delicate for pulse attack.  Those items have their own draw-backs as you should know, but at least they have a fighting chance of surviving pulse.

There is no escaping the damaging effects of pulse unless you are underground or in a shielded building.  You will just have to have a Faraday shield to prepare for that awful future day which we all pray will never happen.

*Modern vehicles, your car or truck, have electronic ignitions and other wiring that is in danger of being knocked out from an electrical pulse.  Most studies say that the car will be completely disabled—it dies, it will not start, it will not run—and the damage is permanent.   The car battery will still be useful, but the car is dead.  Shielding a vehicle is not easy;  it would involve placing it inside a Faraday shield that totally encloses it—top, bottom, and all sides.  Too, if the vehicle is in use and is hit, you can strip it for parts, but its electronics are fried forever.

Some concern needs to address your motor generator, the thing that has a gasoline motor that generates 120 volts of AC that can run your appliances.   Like a non-electronic motorcycle, a generator is very simple and not likely to be affected by pulse.  However, attached electric extension cords can act as antenna to feed pulse back to the generator, so it is better to have it unplugged and turned off to be super safe.  See the irony noted below.

**An ironic fact is that if your electronic device is IN USE and thus out of your Faraday shield, it will be damaged.  This fact provides the prepper with a real dilemma.  Inside the shield, the items will not function.  Outside the shield and in use, the items are in danger of pulse destruction.  Thus, it helps to have back-up copies of your electronics, one inside the shield and one in use.  It is highly unlikely you will receive more than one pulse, so once the pulse flashes, you can take all the gadgets out for full use.

CMEs from the Sun do give warnings which scientists can tell people about.  However, the damage of huge CMEs is so great that storing electronics immediately upon any warning is a very good idea.

Thermite: I invented it

In the advanced chem high school class, I wanted to create some rocket fuel.  I tried number of things, like a good scientist, until I came up with a combination of ingredients that did what I wanted… long hot burn.

I had to use a magnesium ribbon to light it.  It was a yellow powder.

My h.s. friend helped.  We put it in a toilet paper tube, stapled one end shut, and lighted the ribbon.  We ran away and hid behind a tree and watched the ribbon burn into the inside of the tube.

It seemed to have failed and gone out.  So he held his mother’s glass coal oil lamp under the tube, on a concrete block, while I pushed the cardboard tube over the flame with my hand.

That is when it exploded.

Molten magnesium burned dots in my eye glasses and we both had our hair singed and eyebrows.  His white shirt looked like buckshot hit it and a drop burned thru his leather shoe.  My hand was burned.  Worse, we both could only see bright orange in our eyes.  I was sure that was to be my permanent vision for my future.  Our eyes recovered.  We brushed the burned ends out of our hair.

We knew this was a great memory.  But we were too close to see the actual explosion and burning.  If only I had known then what I had invented.  Oh, well.

The Real Nature of the Universe

HOW THINGS REALLY ARE:  Trying to be Awake in a Sleepy Era

C. Harpole, Feb. 20014

In 1958 at the age of 15, I asked myself about the nature of the universe.  I decided that the big bang theory was correct and not the steady state one.  I asked where did the universe/matter and energy come from.  My answer was that “there is a strain on nothing to become something.”*   Quantum mechanics has confirmed the latter and other science has confirmed the big bang.

In later years, I kept thinking about the details of the extension of what science, then, was puzzled about.  I found no help in current science and was very skeptical of the ultimate power of mathematics to solve these problems in ways that would always transfer to the experimental arena.  But, because I saw that every new breakthrough in math and science changed or negated what came before, I knew that Einstein’s theories were only partly correct and that the next breakthrough would change or even nullify the scientific giant of our times.  It is obvious, for example, that the speed of light can be called a constant for a math formula needs, but it does not really exist at a fixed speed.  But, I also knew that this aspect of my thinking was only scratching the surface.*

I started to read about Buddhist ideas back in my teen years.  Returning to these ideas over my next thirty years, I kept being fascinated by the stories from Buddhist legends that the highly advanced, “highly realized,” monk/meditator masters could make footprints in solid rock, could travel in time and to other parallel universes, could actually exist in more than one place at a time, and, overall, knew areas of science much better than science of that day did.  In 1998, I got to see some of those stones with the footprints.  By that time, I had formed my theory of how things really are.  Now, twenty years later, quantum mechanics is filtering down to television shows and something like popular consciousness.  Now, some Western scientists in quantum physics are finally reaching toward what the Buddhist masters knew (and do now know) back even at the latest incarnation of Buddha himself, centuries ago.

I came to know then what quantum physics is now beginning to assert.  That is that, of course, matter and energy are interchangeable but also that matter can act like a wave of energy and that matter/wave energy can be in more than one place at a time, and further that time itself is not what we ordinarily think of.  I felt then and now that everything that was/is/will be is all “happening now.”  That is, that “events” are not located in “one time,” but that they always ARE.  This explains how the Buddhist masters could perceive past and future by disabusing themselves of the idea that all this is impossible, but instead by simply looking and being able to “see” these “always are” events back or forward in time because these events actually “always are” and are there to see.  Then, it is but a small step while looking into the past or future to go there, too. 

This can be understood if we see what quantum mechanics is now suggesting and that is that conceiving is creating.  Einstein said that he believed that the Moon was still there even when he is not conceiving of it nor sensing it.  Einstein was wrong.  To conceive/sense a thing or an idea is to make it manifest;  not to conceive/sense means those things/ideas are just not “there.”  Of course, this issue remains solely within the human realm;  there are other realms which may function in other ways. 

[To add a note here, it is very important to know that what anyone thinks is impossible will almost always keep him from seeing the possible.  The Buddhist masters simply came to be sure that what is normally called impossible is indeed both possible, and for them, ordinary.  Their situation then comes about when the limits of ordinary reality are deeply and genuinely removed.]

Remember Buddha said only that he was “awake.”  All the profundities are capsulated in that one word.  He was/is awake to these factors—including that “to conceive is to make” and that ordinary human rejection of the supposed impossible hamstrings humanity to an erroneous view of how things really are.  There is more to be “awake” to;  see below.

A piece of this discussion must involve what quantum physics now calls “quantum entanglement.”  This idea, articulated in a way in Buddhist lore for centuries, says that two particles (I substitute several or many particles, but that is another story) can be observed to behave in correlation to each other.  These entangled pairs exhibit opposite characteristics but the oppositions are directly correlative one with the other.  Neither one of the pairs determines the other, no boss, but both definitely and simultaneously exhibit correlations which are complete (if opposite, one + and the other -).  That is wondrous enough, but the experimentations go on to show that the two in the pairing are directly correlated regardless of the space between them.  Thus, a change can be introduced to particle A and its entangled partner, B, will be in a correlative sameness (that is, B will change in response instantly–absolutely no delay—and actually must be said to be a correlative same).  Because A and B can be vastly separated in space (time apparently not an issue), communication of information (and exchange of particles) over gigantic spaces is possible and instantaneous.

Then, if a Buddhist master wished to “be” in his correlated or entangled other in the paring, he would be there, not just travel there, but be there and likely is there all the time.  Thus, he could be in two places, at least, at once.  The theory goes, in fact, that the master would live in both places at the same time.  However, he may be an “opposite” (whatever that means) over in his other pair self.

Today, the quantum entangled pairs are only single tiny bits of matter, electrons, but it seems more than likely that single tiny bits of matter, the pair, could be chunks of bits or whole human beings (or other things larger).  It seems reasonable that if one tiny bit of matter exists in this way that size should not really be a limiting issue. 

I postulate that quantum entanglement occurs among many bits of matter.  This idea explains how I can be in two parallel universes (or who knows how many parallel universes) at the same time.  So far, I have only been able to sense two universes, but that could be my self-limiting—my thinking of only two at first and then maybe I have difficulty of adding more.  Perhaps I only was provided two in my plane of existence.  Otherwise, it could be that two is the limit of quantum entanglement pairs.  But then, I always doubt limits.

I do not doubt my two parallel universes “visits.”  I am completely puzzled at how and why I have awareness (consciousness of) of only one at a time.  I also wonder about my paired self over there in the other universe.  I guess we exchange places simultaneously.  It happens when I am not in my conscious not-sleeping self which could be expected to be self-limiting (again, as above), but during sleep the transition must be easier.  I am working unsuccessfully so far at being awake during the change over.  (I am also not aware of being in two places at the same time.)

More, quantum mechanics today postulates that there are many universes and that changes in one are not necessarily reflected in oppositional duplicate in the others.  This is definitely part of current quantum theory, but it does seem to contradict the quantum entanglement idea of “pairs only” and pairs always in oppositional relation.  That is why I postulate that the parings can be multiple, perhaps infinite in number.  Beyond this topic is the supposition that the universes are only levels of infinite other layers of other “places/times” that either contain or live next to our idea of our own one universe. 

Add in the Schrödinger’s catreasoning which seems to say that I could be dead in the other universe.  Or, at least, at one moment of space or other, I am both dead and alive.  Then, events occur so that I either die or don’t die.  If I have understood the Schrödinger’s cat thought experiment, I could not really visit the other universe, especially on the chance of being dead there, because this thought experiment seems to limit the cat and I to one continuum of time/space and limits the possible futures, dead or alive, to only two options, either of which are determined by past events.  I say, my idea, that the cat is either “already” dead or is “already” alive because of the idea of a continuum of all events/times—the idea that all things are and are all the time of past, present, and future (as stated above).   I am not sure if Schrödinger’s cat’s “arena” has parallel universesor just two possible futures and one becomes “the one and only.”

Returning to the previous paragraph—“in oppositional duplicate”—there is a possible extension of thinking that relates to Buddhist cause and effect and to the idea that time is a continuum with all pasts, presents, and futures all present to any one powerful master observer at once.  This extended idea is called “retro-causality.”  This idea says that like “the past can affect the future,” the future can affect the past.  This idea has support in quantum theory where a projected particle, an electron, seems to go back in time when an event happens to it (exposure to photons, in experimentations) in a specific way.  Importantly, when the event happens to it, at that moment the particle is in its future relative to its later retrograde action.  Thus, the particle’s future affects its past.

It will be interesting to test if Buddhism is concerned with the future, or even the present, affecting the past.  This situation would “reverse” cause and effect where the effects would modify the causes and would do so actually rather than in the realm of saying, “Yes, what happens now can change our perception of its causes.”  The actual causes would be changed by effects happening in the future.  Buddhism and thinking of all kinds are ripe for consideration of this matter.

There is a Standing Wave in all of everything. 

 

Along the way, as a senior in high school, I invented thermite, but that is another story.  Also, see “strain on nothing” in another essay.

Preppers use of Ham Radio

HAM RADIO AS A PREPPER TOOL
By Charles Henry, K4VUD, ham radio operator

Many preppers want communications options during times of vast calamities that shut off normal cell phone and other means for a long time. Often, ham radio is suggested for this use. Ham radio is not simple, like a walkie talkie or cell phone, but it can have a vital place during smaller or world-wide catastrophes.

Ham radio, amateur radio, is a hobby as old as radio itself which today is practiced by over a million people world wide. Often self-taught in electronics and radio functions, hams vary in activities from building their own radio sets to experimenting with satellites. Each ham must pass a government test to be legal to transmit. The ordinary use is to try to reach many places on the globe as an accomplishment or to just talk in an informal chat with an interesting person nearby or far away. The point is to use the hams’ knowledge of voice, Morse code, TV or data transmissions to communicate anywhere to fellow hobbyists. Ham radio has a long history of providing vital communications in emergencies where all other methods have failed.

Emergency communication is the aspect preppers should know about.

Preppers need two kinds of communications needs in times of calamities: contact among the immediate prepper family or group and contact with other preppers and with officials that may provide help or vital news.

Contact among family…. Unless the family is wildly disbursed (like hundreds or thousands of miles), prepper family/ group members need what is called INTERCOM. Intercom is short range (couple of miles) radio system which will keep all members in contact with all other members all the time. This system can be the little ear phone and microphone devices you see on police or military in movies (the MISSION IMPOSSIBLE folks have that) or just a walkie talkie for each person. There is a wide variety of walkie talkies which work on various radio bands—business band (like seen on a big construction site) or personal bands which include or are new versions of the CB system or the ham radio bands.

INTERCOM units need to be very portable, reliable, all be identical in bands covered, and have easily recharged batteries (removable is best). They must be simple to use with a volume control and a push-to-talk button. An ordinary system allows only one person to speak at a time, but allows all to hear the speaker. A group of excited people all pushing the talk buttons at once will jam the system, so training is a must. Two-channel units can be placed with the main bosses of the location so that the leaders can talk privately away from the group channel. Commercial business band walkie talkies are best because they are rugged and made for rank novices to use. Their frequencies are color coded, often by the case color. These type units will work well for group INTERCOM.

Whatever type of INTERCOM is selected, the danger is that others can listen to all that is said over them. Thus, if junior is crying for his Mother and disclosing his location, anyone within the short range of these radios can listen in. Too, business band radios have a few very common bands, so finding you on your INTERCOM is easy. See below for discussion of how to avoid this problem.

The other communication that may be needed is LONG RANGE radios. This is where ham radio comes in. LONG RANGE radios can work over many miles or around the world. The distances they work on can be controlled to avoid broadcasting to areas of danger, but whatever is said over a ham radio can be heard by anyone with the proper receiver. People can talk in some kind of made up code for a bit more privacy, but using standard Morse code does not automatically provide total privacy, but gives some because few people know Morse. LONG RANGE radios must exist at both ends of the communication channel.

Ham radio sets do have long range. The sets include a receiver and a transmitter in the same box. Having a receiver is an excellent prepper survival tool because listening is possible to any news or other calls which gives excellent intel (intelligence information like spies do), but just listening does not give away the location of the radio set. A short wave receiver set will do this same function with no transmitter included. All radio transmissions can reveal the location of the transmitter, either by special “sniffer” equipment or by some mistaken comment from the person speaking. Advanced radio finding equipment, likely owned only by the military, is very sophisticated, but an ordinary ham can only get a general idea unless very close to the transmitter being sought.

LONG RANGE transmissions need to be short and identified by recognition of voices or some simple code (a transmitted voice just calls himself George). Basically, LONG RANGE transmissions should be limited to people inside the family or group. Talking to strangers by radio can bring trouble. Thus, unless one group has a familial bond with another group at a great distance (over five miles), LONG RANGE transmission should be kept at an absolute minimum. Exceptions could be dire emergency transmitted calls, for example, but he danger of that has to be evaluated.

If two or more bonded groups wish to use LONG RANGE communications, they must use some kind of coded talk, keep transmissions short, and work on a predetermined time schedule. The latter two items also hold down on electricity needed.

LONG RANGE equipment has another huge draw-back—an outdoor antenna is a must for effective function. These antennas are not really small and certainly call easily visible attention to the preppers’ site. Antennas require maintenance and are easily damaged by attackers or even people just some doing malicious “fun.” It is very difficult to protect a good antenna on top of a 50ft tower, for example. If the prepper wishes to install a temporary antenna, made of wire, then there is the danger of exposure during the set-up and take-down. The rule is that the larger the antenna and the higher, the better it will work. Hams have written articles about making stealthy antennas, but the performance is limited (and will need testing). Lots of experimenting will be needed to discover just how small an antenna can be made and yet do an adequate job. In fact, it is the antenna that is most difficult for a beginner to deal with. Anyone can run a radio with minimal training, but installing, testing, and getting good results with antennas will take a professional or a ham operator’s help (and it is not a short job).

LONG RANGE radio equipment will most likely have to be from the ham radio market. Surplus military radios are rare and difficult to get manuals about. There are two kinds—tube type and transistor type. The good news about a tube type ham radio is that it is more resistant to EMP and operator misuse. However, replacement tubes must be found and kept on hand, and the radios are only old; all tube type radios are over thirty years old or older. There are virtually no units to be found that are new in storage. The Collins Radio Company made some very rugged short wave transceivers (receiver and transmitter in same box), model KWM-2, that were used in Vietnam and ham radio collectors often can refurbish such units to very good condition, but may end up costing a couple thousand dollars. The operation of these type units are not automatic and abusive or ignorant adjustments will burn the radios out. Training is required.

Brand new transceivers, and some newer used items, are “all transistor.” Transistors are more delicate, especially in EMP (note this includes all new walkie talkies, too). With minimal training, these units are easier to use, especially with a built-in antenna tuner, a must, which will automatically adjust the output transistors to the antenna. Many will run on a 12 volt car battery, but badly regulated generator voltage can damage them. Best to just charge the batteries disconnected to the radios, and then connect them.

At the height of popularity of the Citizens Band (CB) use, millions of these radio transceivers were sold. In their unmodified form, their 5 watts transmission power is only good for five to ten miles over open terrain. They fit in cars well and can have simple car antennas. Thus, they are very good to communicate car-to-car in a convoy, saving walkie talkies batteries. Many CB enthusiasts built modified, higher power CB radio systems. Getting one of these is cheaper than a ham set and has lots of transmit power; however, the CB radio has only 40 channels within one frequency band so it is easily spied on and many times limited in transmit range due to that band’s limits—regardless of transmit power of 1000 watts or more. Because so many survivors will have access to CB radios, the prepper must have one or two at least for listening.

Transmit power can be increased by ham radios and CBs alike with a second box called a linear amplifier. This device connects between the transceiver and the antenna and automatically boosts the output for talking. These are best used with the automatic transistor radio sets and need to be automatic also. The linear amplifier must, then, have a built in antenna tuner inside that amplifier to keep from having to know how safely to tune these items. Two common units with that capability are the Yaesu FL-1000 and the ICOM IC-PW-1 or similar ICOM models; both are now sold new or used.

Note that additional transmit power will not mean that you can hear better; only that you will be better heard. The higher power means that radio can be sniffed and found easier. The antenna still needs to be as good as possible for hearing purposes. Linear amplifiers take lots more electricity, like even 20 amperes.

A complete LONG RANGE short wave transceiver, amplifier if needed, and the necessary antenna can provide 24-hour communication to a variety of distances world-wide. It can be argued that the best use of this equipment is for listening. If there is a redevelopment phase after a huge calamity, this radio system could be of vital help in transmitting, too. A good working ham radio could easily be the center of reestablishing civil order and a return to some kind of post-calamity society. It is a good system to have on hand.

NOTES:

-DODGING LISTENERS
In using INTERCOM or LONG RANGE radios, operators can avoid being heard by snooping invaders by changing the frequency bands often and in a pattern only known to the inner group. For example, after a few words, a trigger word, like “change,” is spoken and all know to change to channel 2 in a pre-arranged order. Soon after on channel 2, “change” can notify all to go to channel 3 and so on. Probably written cheat sheets will be needed. One can see that as the complexity rises, problems of confusion also rise. A LONG RANGE radio operator pair would need this cheat sheet well before any calamity because they are widely separated.

-BEING LEGAL
Almost all radio transmissions are controlled by governments both to direct no over- populating the radio bands and to be able to trace illegal uses of radios (like drug traffickers). The first is done partly by having a test which measures the applicants’ knowledge of adjusting radios and of radio laws. Also, UN and other international treaties rules set frequency bands all over the world which keep police radios away from TV broadcasts, for example, and limit ham radio operations within set bands, too. Fortunately, the earliest telegraphers were trained to high standards of keeping secret the messages they passed and maintaining equipment in good order. This tradition of honesty has transferred over to ham radio operators who are very defensive of their bands and to improper uses of them. This tradition affects the prepper, as seen below.

All but a few bands for low powered citizen radios (and all cell phones which are also radios) are closely regulated and monitored by governments to enforce the radio laws. Because LONG RANGE radios will transmit over national borders, governments try to make their citizens obey the laws to avoid confrontations with neighboring nations. Enforcement, of necessity, means governments must know the location of radio transmitting operators and equipment (some governments also want to register all short wave radio receivers, too). A system of assigning call letters, different for each individual ham world-wide, to operators and the necessity of their transmitting those letters frequently helps identify the honest from the law breakers. The culture of ham radio is extremely scrupulous in obeying the radio laws, the operators protect and correctly use their call letters like their own names, and hams do extensive self-policing—correcting their own and even reporting bad apples.

Because hams are so well behaved, the law breakers, called pirates, are more obvious. A pirate will have no legal call letters which immediately shows him up. Hams help track law breakers often.

What all this legal stuff means to preppers is that the prepper needs to either obtain a license himself or be very careful testing his communication equipment illegally. American preppers can read http://www.arrl.org for the way to pass tests and get a legal license to use ham radio transmitters inside the ham radio bands. This is the ideal plan because having a real license opens the prepper up to help from hams, many who delight in helping a fellow ham (even putting up antennas, etc.). The ham license opens many bands to the licensee all the time. Using the ham radio sets and gaining experience with how radio waves behave will make the prepper better prepared.

In the USA, radio receivers require no license. However, if the unlicensed prepper tests his transmitting equipment, he must do so carefully with short test transmissions. He can escape the watchful oversight of hams by adjusting his own radio to transmit outside the ham radio bands. Too, the job of monitoring and enforcing all radio transmissions is overwhelming, as you can imagine. Pirate radio users on commercial fishing boats off Vietnam and Malaysia chat often. Rebellious military groups use unapproved bands to coordinate military attacks. Drug traffickers use radios to direct their travels. Catching them all would be like netting all mosquitoes at a backyard BBQ. Thus and sadly, many misuse the radio bands and the practice in the short wave bands is getting worse. Enforcement in these bands are not nearly as important as controlling military and commercial radio transmissions to and from satellites; satellite bands are well away in frequency from the HF short wave ham bands.

Note that most all ham radio transceivers can be adjusted to work outside the ham radio bands. No one should break the law this way. It is much better to simply pass the test and get a legal ham license.

-BEING CAUGHT
Because getting a ham license includes identifying oneself to federal and other authorities, including legal names and addresses, some preppers may be resistant to having such information on file. However, it could be argued that any calamity that stops the use of currency, food deliveries, electricity, and riots and so on—the real sh^t hitting the fan—will also stop government agencies taking the time to look in computer files (which no longer work) to find a lonely prepper hiding with his ham radio set. The idea that any part of the governments could organize and enforce mass round-up of radios and guns, for example, boggles the mind considering the many other truly overwhelming problems involved. Even military tanks can run only so far without fuel, and getting men to stay at their posts while their families and society are crumbling calls into question how “the government” can come and get you. Anything is possible, but it appears that in the event of a massive, world-shattering complex situation, government officials and military will be much more concerned with saving themselves. For example, it is one thing to fight in Europe (WW2) and an entirely different thing for a military to function with the whole world falling apart. A prepper must examine these factors and decide what is likely best for him and his group.

In sum, ham radio is an excellent part of the preppers’ preparation. It may not save the family or group, and it may be broken just when it is needed. It requires electricity and competent operation. The prepper is best using ham radio if licensed and thus trained in ham radio use. A good working radio should be a part of the preppers’ enclave or hiding place.

  1. With the rotator connector facing you, position the Rotation Limiter arm to the right until it just touches the right stop. FAILURE TO DO THIS CORRECTLY WILL DAMAGE THE ROTATOR

 

  1. Install the rotator top with the raised alignment mark on the top half of rotator case matching the raised alignment mark on the bottom half of the rotator case.

 

  1. Recalibrate the rotator and control box according to the instruction found in your Operating Manual.
