COMMUNICATION FOR SURVIVAL
© 2006 RogueTurtle.com


Two tin cans and a string. It still works. But in a survival situation, you just might need something a little more modern. The ability to receive information in a timely manner will greatly increase your chances of survival in almost every scenario you can think of. There are many different ways to get information. More than you're probably aware of. You just have to plan ahead to have the necessary equipment with you. Yeah, once more we're back to the 6-P's: Proper Prior Planning Prevents Poor Performance.

Communication requires three parts: A sender, someone talking to you; a mode of transmission, telephone, for example; and a receiver, which is you. Talking face to face is always the best form of communication, but when you and your friends and family are scattered to the winds, this is impossible. You have to rely on some form of electromechanical means to assist you. I'm going to examine most of these systems so you can decide for yourselves which system will be best for you.

COMMUNICATION SYSTEMS
When the Power is OFF

1. TELEPHONE

The most obvious first choice is the telephone. Mr. Bell's little invention that changed the world. We all have those ugly black wires hung on our houses, running through the walls. Now, the newest rage is the "cordless phone". Pick it up and walk anywhere in the house to talk. No more dragging a curly and tangled cord behind you. I have one that has two handsets. Actually, they are a very small, limited range radios, broadcasting around your house. But, when the power is off, so are the cordless phones.


The older rotary dial phones and push-button phones don't use radio to transmit or receive signals. They don't even need household electricity to work. Your house can be totally blacked out and the phone will still work. Why? Because the phone companies' power is still ON. Most phone companies have backup generators. The real trick is finding the ringing phone in the dark.

The limitation that the telephone has is that it is still tied to a hard-wired plug-in jack and the cord only goes so far before you have to stop moving. We've all pulled these phones off the desk or off the wall by tugging just one more inch of reach out of the cord. The other limitation is that there are only just so many phone wire (pairs) available for anybody to use. Once they are in use, nobody else can talk until a line comes open. This has caused many a customer to have a dialed number fail to connect.

A. UNDERGROUND UTILITIES

A newer trend in modern neighborhoods is to free up the landscape from unsightly poles with wires strung all over the place. So, they bury them all in the ground. Looks good. But, the first time someone digs a hole, they are bound to cut the wires. I think it's a law. The second problem is that anything buried gets drowned when it floods. Electrical wires, TV cable wires and telephone lines buried underground will short out when flooded. This is also a law. Underground service vaults (where the connections and relays are located) fill up shorting out the whole thing. Until these dry out, you are out of luck.


B. ABOVE GROUND UTILITIES

"Damned if you do, damned if you don't". Above ground lines are even more susceptible to damage from other sources. Hurricane and tornado strength winds blow down trees and short out everything. Cars and trucks crash into them. Crazies blow them up. Forest fires burn them up and avalanches crush them. All utility lines are vulnerable to be damaged or destroyed. At least underground, they won't burn up.

C. FAX MACHINES

The facsimile machine is just another type of telephone. Only this one needs even more electricity to run than the telephone itself. It is actually a type of mini-computer tied to a phone line that received digital "codes" to make an accurate copy of something somebody sends you. So, if your house power is off, the fax is also off.


2. CELLULAR PHONES

Cell phones operate within cells, and they can switch cells as they move around. Cells give cell phones incredible range. Someone using a cell phone can drive hundreds of miles and maintain a conversation the entire time because of the cellular approach. The problem with the cell concept is that at the center of each cell is a tower that is powered by electricity. Without electricity at the tower, the entire cell phone system falls on its collective behind. No electricity – no cell phones.

Of all the competitive communications systems out there, the cellular phone business has got to be at the top of the list.


3. SATELLITE PHONES

A satellite telephone, satellite phone, or satphone is a mobile phone that communicates directly with orbiting communications satellites. Iridium was the first satellite phone company. Depending on the architecture of a particular system, coverage may include the entire Earth, or only specific regions. The mobile equipment, also known as a terminal or earth station, varies widely. A satellite phone handset has a size and weight comparable to that of a late 1980s or early 1990s cell phone, but with a large retractable antenna. These are popular on expeditions into remote areas where terrestrial cellular service is unavailable.

The advantages over the land-based cellular phones is obvious. You talk and receive phone calls on your hand-held equipment that uses rechargable batteries. The satellite has its own source of power, the sun. It is the ultimate alternate energy project so far. All satellites are, for that matter. You don't use household electrical power EVER to use this system (except to recharge the battery). You can also recharge the battery off of a plug into your automobiles' electrical system. As long as your batteries keep a charge, you can talk anywhere in the world...almost.

The "almost" means that if you call somebody on a standard cellular phone, it still won't work if the power is not working around the cellular phone. It takes TWO satphones to guarantee communication. All other type phone systems will eventually fail when all power is lost...except the satphones. They just keep on, keep'in on.

Sat Phone companies will lease you a telephone and charge by the minute just as they did if you were around when cell phones first came out. As competition increases, the rates will go down. One company has 66 satellites up there for world-wide coverage.

THE SATELLITE PHONE IS BY FAR AND AWAY THE MOST RELIABLE OF ALL THE ELECTRO-MECHANICAL SYSTEMS AVAILABLE TO THE SURVIVALIST. While there are moderately high-end monthly fees, the safety and protection they provide are head and shoulders above any other means of communication.

4. AM and FM Commercial Radio

All the countless radio stations in the country will NOT all go off the air at the same time. A disaster in your local area will probably not affect a town 25, 50 or 100 miles away. That means that they will be broadcasting news and weather to you, provided you have a radio to hear it. For a national level emergency, the start will be from the EMERGENCY ALERT SYSTEM.

The EAS system was established by the FCC in November of 1994 with the approval of Part 11 EAS rules. The EAS replaced the Emergency Broadcast System (EBS) as a tool the President and others may use to warn the public about emergency situations.
All participating commercial radio stations in the country, in times of national crisis will be issued an EMERGENCY ACTION NOTIFICATION MESSAGE:
"This is an emergency action message requested by the White House. All broadcast stations will follow activation procedures in the EAS Operating Handbook for a national level emergency. The President of the United States or his representative will shortly deliver a message over the Emergency Alert System."

All licensed radio stations receiving this notification must then make the following announcement:
"We interrupt our programming; this is a national emergency. Important instructions will follow."

The next announcement (for participating manual operations...that is, there are people there working and not a pre-recorded program) will be:

"This is an Emergency Action Notification. All broadcast stations and cable systems will broadcast this Emergency Action Notification Message. This station has interrupted its regular programming at the request of the White House to participate in this Emergency Alert System.
During this emergency, most stations will remain on the air providing news and information to the public in assigned areas. This is (station call name). We will continue to serve the (EAS local area name). If you are not in this local area you should tune to stations providing news and information for your local area. You are listening to the Emergency Alert System serving the (EAS local name) area.

Do not use your telephone. The telephone lines should be kept open for emergency use. The Emergency Alert System has been activated.

We will also be acting as a message distribution and relay source to other broadcasting stations."

The priorities for Emergency Action Messages to be broadcast are:

Presidential messages to be carried "live".
Local area messages
State messages
National Information Center (NIC) messages


Termination of the Emergency will be almost a repeat of how it started, but the final notification to the radio station will be:

"This concludes the Emergency Alert System. All broadcast stations may now resume normal programming operations".

Stations then will return to "normal" programming however they see fit.

It is also important to know that this same Emergency Alert System can be activated at the local and state level for local emergencies, not just "national" emergencies.

ALL THESE FEDERAL AND STATE LAWS MEAN NOTHING UNLESS YOU HAVE A GOOD RADIO TO RECEIVE THESE MESSAGES. YOUR LIFE COULD DEPEND ON IT.

5. Citizen's Band Radio

"Breaker one-nine for the Rubber Duck" ... Movie lore is full of the uses and abuses of the CB radio. Truckers have for years installed these radios in their trucks to keep them alert on the road. Any citizen of the United States can purchase and install a CB radio without needing any license or permit. Outside the US, there may, or may not, be restrictions.
The FCC has set aside a band of frequencies for CB use: All frequencies are MHz.

CHANNEL  FREQUENCY
01                 26.965 MHz
02                 26.975
03                 26.985
04                 27.005

36                 27.365
37                 27.375
38                 27.385
39                 27.395
40                 27.405


Channel 09, in red, is the emergency channel, but to be honest, it is not monitored very much by anybody.

Channel 19, in blue, somehow got adopted as the unofficial truckers channel. If you monitor this one, be prepared for all sorts of graphic traffic conditions...language varies.

The primary use for CB is while traveling to and from home, either by talking to a home base radio or from car-to-car. CB radio allows you to keep informed with up to the minute status of the occupants in the vehicles and the condition of the vehicles (fuel status, etc.). You can coordinate group efforts between vehicles, such as a mutual place to stop for fuel or food.

The other use for CB is to monitor the road conditions both ahead and behind you. The truckers will let you know about the traffic delays, and usually graphically describe how long they have been stuck in stalled traffic. Time is money to them.

From a lot of years of experience with CB radios, I can tell you without hesitation that "going cheap" will be a really BAD IDEA. Cheap radios do not transmit or receive very well. The radios are limited to 12 Watts of power ONLY and you won't even get that with a cheap radio. At the maximum, most CB radios (unmodified) will only get from 3 to 5 miles range. This, of course, depends a lot on your pocketbook.

CB MOBILE UNITS

Some expertise is needed to wire up and install a CB radio without shorting out your ignition and battery system. All the units sold in the USA use 12 volt, negative ground systems. The more powerful the radio, the heavier the power wires have to be. Here is the radio I use:

Cobra 148 GTL CB Radio $159.95

12 watts power SSB RF output increases range capabilities with SSB operation. 4 full watts AM RF power output. Dual converstion AM receiver - maximum frequency response and spurious rejection. Professional driver-requested improvements include a front panel microphone connector, tactile controls (for added convenience and safety when adjusting functions).
Includes microphone, mounting bracket, mount knobs, & power cord.
Approximate Dimensions:

Height - 2 3/8"
Width 7 7/8"
Length - 9 1/4"
Add approx 1" for knobs on front & 1/2" antenna connection on back.



Additional Features:

40 CB Channels
Front Panel Mic Connector
Full RF Power Output
Dynamike Gain Control
RF Gain Control
PA Function
1 year warranty*



But, you're not done with the expense yet. Every good radio uses a good antenna. Without the antenna all you have is a brick. Here's the one I use:

High Power Ability To Handle 5,000 Watts AM, 20,000 Watts SSB (ICAS) Made with high impact Mobay Thermoplastic 6 gauge solid copper silver-plated wire Exclusive low loss coil design 62" 17-7 PH Tapered spring stainless steel whip Frequency range 26 MHz to 30 MHz Weather Channel Ready Available in Roof Top, Trunk Lip, or Magnetic Mount Removable coil for safe storage & garage entrance Weather Cap included to protect mount when coil is removed 2 year warranty.
Price: $99.95

You may be asking yourselves why I use an antenna capable of handling 5,000 watts when the radio only puts out 12 watts? The answer is that I could "expand" my capability beyond what the factory and the FCC says I can use. I won't admit to anything, but there are ways to "boost" or "kick up" your power for transmission. Since telling you exactly how to do this would be skirting some law or another, all I can say is that if you get with a group of CB knowledgeable people, someone will know how to do it. Inside some handheld radios, there is a capacitor that can be "clipped", boosting the output power from 2 or 4 watts to 12 watts. From there, the outgoing signal can be further boosted by adding a LINEAR AMPLIFIER that goes to the antenna. The going rate (used to be) about a dollar and a half per watt output. A 400 watt amp would be around $600.00 (new). You can get better deals on Ebay, if you know what you're doing.

CAUTION: Not all amplifiers work on CB. Find an expert and find out EXACTLY what you need.

CB BASE RADIOS

These radios attach to a much larger antenna than the mobile units. It can, therefore put out and receive much better. They usually are supplied with a 120 volt/AC power source, but almost all of them can be connected to a 12 volt/DC battery and still work very well. As always, the charge in the battery is the limiting factor. Any radio, however, could be a base radio, it is just installed indoors, instead of in your car.
I have a couple of base radios I can use, but right now they're not in service. Here's an example:

RANGER'S NEWEST 10 METER RADIO $ 279.95

Features:

10 Watts AM, 25 Watts SSB
Adjustable Dual Echo (Not Just On-Off!!)
Selectable Talk Back, Roger Beep and Mic/RF Gain
6-Digit Frequency Counter
6 Position Band Switch With +10KHz Offset




Cobra power mike - 4 pin. Good for Base or Mobile radios. $19.95
Wired for Cobra, Connex, Uniden, Galaxy, General, Ranger, 4 pin models only and the Magnum and Cobra 148 (new) 4 pin version
RogueTurtle and clan each use one of these and they are terrific.
Has a 9 volt battery to send a "boosted" signal into the radio before it ever gets transmitted. Improves the broadcast of your transmissions and adds clarity to the spoken word.



Since it's attached to your house or shelter, the base antenna can be much larger than the mobile antenna. This helps collect weak signals from long distances, and greatly improves the power output of any base radio.

The MACO Comet $239.95 plus coaxial cable (extra)
A long-distance 6-element base station with 12.5 dB gain and dual polarity. This antenna is designed for CB'ers who want a booming base station, but space is a problem. And, it has the MACO 2 kw power handling capability!



This is just a "teaser" on CB equipment. If you are serious about getting a Citizens Band radio set up, you need to sit down with an expert and tell him or her what you need. Mixing incompatible components will be costly and could damage sensitive radio equipment, putting you out of business before you even get started. There are uncountable combinations out there, but they are NOT all compatible with each other.

For car-to-car information, you can't beat the hard-wired CB radio. It has a range of 12 to 30 miles depending on your "improvements", and is a very reliable form of communication.



6. AMATEUR (HAM) RADIO

Ham radio operators are a special breed of enthusiasts who take their radio skills and craft very seriously. Broadcasting on a relatively small range of closely controlled radio frequencies, they virtually police themselves. In some advanced CB radios, using a SSB or Lower Side Band setting can bring your CB dangerously close to the frequency used in the 10 meter or 12 meter bands. I have been chewed out on the radio more than once by Ham operators who felt I was infringing on his sacred bandwidth. I, of course, apologized and changed channels immediately.

Unlike CB radio, all Ham operators are licensed by the FCC as well as their local clubs. Many frequencies are dedicated not only to Ham operators, but are restricted to a certain class of license that is eligible to use the channel. I'm not a Ham operator, so I don't know all the details, but in order to get a "full ticket", that is, fully qualified in all channels, takes years and years of work and study. There are a series of tests administered to determine skill level in the operators. They take great justifiable pride in their skill levels, and (unfortunately) many look down on the "lowly" CB people as some sort of sub-species. At least I'm not a geek.

Unless you're willing to get into a local radio club and study your brains out, Ham operations should probably be avoided. Their equipment and antennas are very expensive, and each bandwidth is monitored, somewhere in the world, by an egomaniac.

The advantage of Ham Radio is their vast world-wide (capability). Depending on atmospheric conditions, Ham operators can talk to anywhere in the world. Talking city to city in the USA is easy...talking to Japan or Germany takes a better radio than CB can offer. However, most Ham operations are fixed, not mobile. They make it hard to "bug out". I cannot recommend Ham Radio for survivalists. It's not flexible enough.

7. MARINE RADIO

A marine radio is mandatory for all boats over 65.5 feet, and optional for all those smaller boats out there. Marine radio is in a very small frequency band that is always crowded on even a good day. They have one frequency called a "hailing frequency", and when you are answered you are directed to another, lesser used channel. With a line-of-sight range of only about 35 miles (barefoot, or non-amplified), the marine radio has limited use. Inland from either coast, marine radios could be used, but there are better uses for your money. I can't recommend using a marine radio for survival purposes, unless you are surviving on a boat. In that case, you should have TWO radios, in case one breaks.


8. AIRCRAFT RADIOS

An aircraft radio becomes very expensive whenever the word "aircraft" is attached to it. It could be the same Radio Shack components available in a $100.00 radio, but when it's an "aircraft radio" the cost doubles or triples. Aircraft radios are set up to use aircraft-compatible antennas that may not be appropriate for your vehicle. I know you can't drive as fast as an aircraft can fly. Many aircraft radios use standard aircraft (24 volt) power supplies not available in most cars. Since the possibility exists for you to interfere in the orderly flow of aircraft traffic, DO NOT USE AIRCRAFT RADIOS. Let the pilots get along with their own problems without you adding to them. Can you tell I used to fly in the Air Force for a living?

Exception: If you are using an aircraft for your bug out, by all means use the installed radios to follow all the required Air Traffic Control regulations governing your flight. Survival means keeping you and your family safe. If the airwaves are not cluttered with misused radios, your flight should be as uneventful as possible. Flight = hours of boredom followed by moments of panic.


9. SPECIALTY RADIOS

These are special radios or radio frequencies you don't normally think about during your normal daily life. Most of the following items are available at a relatively low cost, or are a free service provided by the Federal Government.

Global Positioning Satellites

(GPS) Over 50 satellites now cover the globe since their first launch in 1978. Handheld and fixed receivers in vehicles now are taken for granted by many car buyers. Accuracy has now improved so much that the GPS signals can guide you through crowded city streets over open and rough terrain. First designed by the military for foot soldiers (who get lost easily), this service is now free for civilian use. However, in time of WAR, the military could just adjust their GPS satellites so that only the military version would be accurate. This takes away the use of GPS by the enemy. It makes sense.

As far as I know, there would be no way to tell exactly when the military decides to make this move. It would, for sure, be during a time of national emergency and/or an imminent threat to our troops in other parts of the world. I suppose that reading your GPS in your front yard in Indiana and finding out the GPS says you are in Alaska would be a very good "clue".

For all other type emergencies (short of WAR), GPS will continue to work on its own power sending signals to earth, to your receiver.

There are now hundreds of models and styles of GPS receivers now in use. Many cell phones have allegedly had a chip installed in them so your location can be followed by "somebody". (Big Brother???) Cars routinely come off the assembly line with GPS services, as well as other costly aids to navigation provided when the warranty is up.

I like GPS. Its fun to use, particularly walking at night, under the clouds, with no way to tell where you are except for the GPS and a compass. Again, if your batteries die, so does the GPS. Use it for a weight to catch fish.

A. NOAA Radio

The National Oceanic and Atmospheric Administration (NOAA) is part of the US Department of Commerce. The National Weather Service is part of NOAA. Since the National Weather Service has a primary responsibility to monitor severe weather, such as tornadoes and hurricanes, they have their own severe weather warning radio system.

By tuning into the local NOAA radio stations, you can keep up to date on the progress of severe weather that is going on NOW, and forecast for the future. It gives a whole lot of weather information that could be critical to your safety. Many manufacturers now produce small, desktop radios that only turn on when NOAA sends out its warning signal for local area bad weather. This system has now been refined down to warning only the radios within a certain geographical area. In the past, NOAA warning radios would go off for a tornado in Cleveland, even if you lived in Tampa. Now, only the Tampa area gets a warning when the weather is bad in Tampa, not Cleveland.

Special radios are for sale that are easily carried in a pocket while you are in the bush. If you think that bad weather is approaching, turn on the radio and get the official version from NOAA.


B. WWV, Fort Collins, Colorado

A little-known, but much used in the military, these frequencies give you the exact date and time. Based on the atomic clocks, this station sends out a synchronous time signal and verbal time announcements 24/7/365. If you are in doubt as to the exact time, remember that the time given is Universal (Greenwich) time and you have to adjust it for your own time zone. GMT, or Greenwich Mean Time (called "Zulu" time in the military) does not change for seasons or local politicians. It does not care if you're on daylight savings time or not, it just gives out the most accurate Universal time possible.

C. WWV FREQUENCIES:

The station broadcasts simultaneously on five distinct frequencies: 2.5 MHz, 5 MHz, 10 MHz, 15 MHz and 20 MHz. Many newer model radios have the capability to receive time signals in this area of the radio frequency band not covered by AM or FM radio. If all you own is the AM/FM radio, you cannot receive WWV radio signals.


D. SATELLITE TELEVISION

"Direct TV", for example.

Another source of information. Most of the hardware and electronics that power the satellite TV receivers is 120 volt/AC current. This is not battery voltage and must be supplied by a generator while in the woods. A lot of campers now have the little dishes mounted on trailers or on tripods that sit by the campfire. All satellite TV dishes must have a clear, unobstructed view of the southern sky because that's where the satellite hangs out. As long as you have gas for the generator, your satellite TV will still work. When your out of gas, the satellite TV goes OFF. I don't use the satellite TV any more, it got to be just too much trouble and went out whenever it rained. Others swear that the rain never affected the signal. I know it did on my set up. I switched back to land-based, ugly black wire cable.

E. SCANNERS

Scanners are another source of information that can be used to search for where the action is. It is important in using scanners that you have some idea which section of the radio band you really want to search. If you spend a lot of money on a scanner, but search in the wrong band width areas, it will appear not to work. Companies such as Radio Shack, sell guides on scanner frequencies that include Fire, Police, Ambulance, Civil Aviation, CB, etc., etc.

WARNING: The scanner must NOT be ON when you are broadcasting from a radio in or around the scanners' antenna. I blew out a perfectly fine scanner in my own truck when I forgot to turn it off and it scanned around to the frequency I was using to broadcast. I burned the poor little thing to a crisp. Lesson learned...an expensive one for me. I now use a less expensive hand-held scanner.

A lot of scanner fans keep close records of the active frequencies in their local area. If you can find one of these folks, have him/her copy it for your use. Now you don't have to wonder who's voice it is you're listening to. Roger? Ten-four. Over and Out.

F. SATELLITE RADIO

The newest radio on the block, Satellite Radio has its broadcasting antenna high above the atmosphere. It can reach almost anywhere a normal line-of-sight radio receiver can get a signal. You can listen to the same station driving from Los Angeles to New York. Curiously, many controversial radio personalities have signed up for Satellite Radio, but I'm not sure why.

Due to their newness, I don't know if these stations are participants in the Emergency Alert System (EAS) I talked about under AM/FM radios. I hope they are. Their use during a national emergency would be of tremendous assistance to those people trapped outside reception areas where the power is out to the local broadcasters. I'll try and find out. If anybody out there knows, let me know so I can update my site.

Satellite radios operate on a frequency not available on normal AM/FM radios, so a special radio has to be purchased just for this system. As long as your batteries hold out, you can get music, news, and (controversial) talk shows. I would monitor the kids use, however, while the naughty ones are on the air.

G. WALKIE-TALKIES

Today's miniaturized walkie-talkies are a far cry from the 20 pound monsters carried by our troops in Vietnam. Kids run around with them in amusement parks keeping parents up to date on their latest mischief (don't we wish). Most often, its parents looking for their kids. These little items use frequencies in a very limited band width, and are very low powered.

There are, however, some pretty good hand-held CB radios around that can be used to augment base and mobile radios by people in your party out of the vehicle for any reason. You can keep track of them while in public areas or off in the woods. Their range is usually about 1/4 to 1/2 mile, so you can keep pretty good track of them as long as they don't wander too far off.
Their limited range and low power output make them only good as an augmenting radio to an existing system, such as mobile or base CB radios.

More expensive and more powerful, VHF and UHF walkie-talkies are available, but usually operate on commercial frequencies such as public utilities, business channels, or taxi frequencies. Most people I know don't use these as during the day they are very busy with business traffic.

H. SATELLITE INTERNET

This access may be worth considering. It's ideal for rural Internet users who want broadband access. Satellite Internet does not use telephone lines or cable systems, but instead uses a satellite dish for two-way (upload and download) data communications. Upload speed is about one-tenth of the 500 kbps download speed. Cable and DSL have higher download speeds, but satellite systems are about 10 times faster than a normal modem.

Firms that offer or plan to offer two-way satellite Internet include StarBand, Pegasus Express, Teledesic and Tachyon. Tachyon service is available today in the United States, Western Europe and Mexico. Pegasus Express is the two-way version of DirecPC.

The key installation planning requirement is a clear view to the south, since the orbiting satellites are over the equator area. And, like satellite TV, trees and heavy rains can affect reception of the Internet signals.


Some systems are specifically designed for mobile use, including the Mobile Universe system shown on the left. The dish automatically tracks the satellite as you drive giving you uninterrupted internet access while on the move.
Their stated price is $139.00 per month.


Laptop computers now range in prices from $600 to $1500 each and many are now wireless compatible.

As I write this article, almost all the information is already obsolete. Advances in computer technology are moving so fast that by the time a product reaches the market, it is "old fashioned" by some newer, faster technology. There is no such thing as "state of the art" computer systems. I cannot recommend these systems for emergency use unless you have really deep pockets and everyone in your party has access to the internet. One system, set up in the final shelter may be a great idea, but I would rather have a satellite telephone than a satellite computer. Nice toy but not back-pack friendly.


10. PORTABLE TELEVISIONS

I grew up during the entire development of television, from its inception in the 1940's and rapid growth through the years. Today, you can get tiny little television sets – in color – for a relatively tiny price. A far cry from the heavy, round screen TV's of the 1950's.

For example, the Casio 4" Handheld TV (EV4500) is sold at Radio Shack for $199.00. It uses either AC power or 4 AA batteries. It has a headphone jack as well as a built-in speaker.

For survival purposes, this type TV would be a pretty good choice, provided you have some way of replacing or recharging your batteries. They say a picture is worth a 1,000 words, and its true. Visualizing a problem is much easier when you can actually see what's going on.

Most TV stations are part of the EAS system so they will all be involved in broadcasting news about whatever the EAS guru's tell them to. The LOCAL news, however, may be of more use to you since that directly affects you in your travels, or at your survival site. If pressed, I couldn't say no to one of these toys without wondering what bit of information I would miss if I didn't have it.

I have a portable TV in my truck that plugs into my 12 volt system. It has a CD and video tape player to keep the kids happy, as well as "rabbit ears" for local news. However, its too heavy to back-pack. I would have to go with the small one if I had to "beat feet" out in the bush.

The major use I see (for me here in Florida) is to follow the track of hurricane winds in my area. If, for some reason, I have to leave my vehicle(s), I would definitely like to have a little set like this to see which direction to travel to avoid the high winds and storms.

SUMMARY

My first recommendation for survival communication will have to be for the satellite telephone. All the forms of communication I have mentioned require battery power, so I have to assume I can recharge my batteries, or will have spare batteries available for whatever I choose.

Next, I would set up mobile CB units in all the vehicles to be able to talk back and forth, and keep updated on traffic conditions. There will be a CB base station set up at the shelter. First occupants in set it up and turn it on, assisting others still on the road.

Without electrical power "from the grid", many services we take for granted today will not be available. Shelters must have some sort of generator system to be able to recharge batteries for prolonged survival.

But, before you rush out and purchase ANY system, be sure that everyone in your select group is willing to also foot the bill or share the expenses. None of these communications systems are worth a plug nickel unless everyone has one with them. Proper Prior Planning (and Purchasing) Prevents Poor Performance.

Eggs, Eggs and more Eggs

I thought I'd share some product information on eggs. You're ideal egg would be from your chickens in the backyard. But that isn't always "ideal" if you live in high rises. There are some wonderful new products out there for long-term storage and also for day to day baking needs. Heck, even for breakfast.

Also, a couple months ago I talked about how you can preserve fresh eggs. Click here to review that blog post again.

Now Is The Time To Look For Winter Clothing

Believe it or not, now is the time for us to be looking for winter clothing. For those of us in the Rockies, we are well aware of what winter brings in temperature, snow and wind. Those of you in more temperate climates, feel lucky now, but be aware that as things deteriorate in our country, you may be forced to move into those beautiful snowy mountains. Here are some thoughts about warm cold weather clothing.

Insulation is nothing more than providing dead air space for heat to be stored. Therefore, higher bulk clothing is more insulating than thin clothing: Wool is better than cotton, nylon, rayon or any other clothing fabric except for maybe polypropylene There are always exceptions to the rule, but for the most part this is a pretty good rule. Therefore, it figures that a high loft down parka, as long as it is dry, will provide the wearer with excellent insulation.

There was a key phrase there. Did you pick it out? Well to remind you, the key phrase was " as long as it is dry ". Snow seldom wets down,only because of the nylon fabric that is used as the outer windbreaker surface and most if not all down parka manufacturers use water resistant material for this purpose. But, if it gets wet, it is absolutely useless in the cold weather.

So, what other types of fabrics provide good insulation. Again, bulk is one key. The next is the type of filling that is used to provide the insulation. After the dawn of the synthetic age, Dacron and other synthetic batting became very popular. It provided good loft, and the synthetic nature of the batting meant that even if wet, it would provide some insulation. Over the years the materials have been specially designed so that the moisture would freeze in the fiber, and then could actually be broken off of the batting, by simply a hardy shake. This was a great selling feature when I was selling sleeping bags at the local sporting goods store. Down was great, but the synthetic fiber was more popular.

The military went one step further by including down, feathers and a synthetic batting for their sleeping systems. The idea being that if the down got wet, the feathers would still provide some loft, and adding the synthetic batting would also provide the loft necessary to be able to stay warm enough not to freeze.

Back in the days of my youth...just about the time that dirt was created, when I went skiing we relied mostly on cotton thermal underwear...the white waffle kind, and then a good pair of down snow bibs, and a down parka. No layering, just a good coat we felt was all that was necessary.

I always seemed to get cold anyway, and so the next year, I'd purchase a bigger coat, until I looked a lot like the Pillsbury Dough Boy. The reason? We didn't take into account the fact that our bodies were sweating, and the good old cotton underwear became moist, lost it's loft and actually became a better conduit for cold than our own bare skin.

Enter layering.

As time went on, we found that if we could stop the wind from penetrating our coats, and we were wearing some sweater type insulating material, the bulk problem disappeared. Then the thin parka/windbreaker became very popular. It was long, and reached nearly to our knees. It had zippers on the sides, and in the front that could be adjusted upwards so as not to encumber our legs and arms while skiing, and we could also regulate the amount of air that got inside the coat. Unfortunately, we were still wearing cotton for the underwear, and it still got damp from our sweat.

We then discovered that wool. It seemed that wool was the best type of under garment to use, because it would not get wet, and the bulk was still there for greater insulation. However, wool itches and can become very uncomfortable for some people to wear close to their skin. Eventually, polypropylene was invented, and with it a breathable, water wicking underwear became the rage.

Open cell foam is an excellent insulator. It is breathable, and allows the moisture to pass through, and still hold the heat in. I was on a winter camp a few years ago. We were ice fishing at a mountain lake, not far from home. The weather was clear, and in the winter, this usually means COLD. Especially at night when there are no clouds, all of the heat escapes skyward. The temperatures dropped to about forty degrees below zero F. A year before, I learned a lesson not to sleep on top of the snow. You have to remove the snow down to the bare frozen ground. I don't remember a more uncomfortable night, as I continued to roll like I was on a spit...but no fire, just ice.

I read about a man named Jim Phillips, who had tested many different materials to see which one was the best insulator. He found that 1" or 2" layers on top of a sleeping bag was the most efficient way to stay warm. Underneath the sleeping bag he used a 3" or 4" open cell foam pad. I tried his system that year when the temperature got so cold. I was surprised at how warm I stayed using this simple system of newspaper, plastic sheeting, foam under pad and a 1" foam cover over the sleeping bag; then wrapping myself up like a mummy in the plastic sheeting. My son and I literally had to open our bags because we got too hot. Most of the others were in their cars with the engines running, trying to stay warm with the car heaters. In the morning the plastic sheeting had the moisture from our bodies frozen on it. A matter of a shake or two, and the water vapor turned ice was gone. We actually breathed in the plastic sheeting. Note, this is not like thin dry cleaners plastic, but heavy visqueen material.

Now, Jim Phillips has designed a foam clothing system that can be used underneath a windbreaker. He also designed foam gloves, hats, boots and other accessories. They do work, but with heavy use, they have a tendency to break down. So, it is wise to either purchase extra clothing, or get the patterns and make some extras.

I have found that if you can find merino wool, this is one of the best layering natural fibers. The merino wool is short stranded, and does not cause itching found in regular wool clothing. The one bad thing is the cost. It is similar to cashmere in it's feel, and it also doesn't pick up the sweaty smell that other wool products do. You can layer 2 or 3 sweaters, and find yourself in non-bulky bliss. I find that if I continue to look for merino wool sweaters and pullovers in the second-hand stores this time of year, most times I can pick it up for about $5.00 a sweater. Also, merino wool socks are excellent for boots as they don't itch, pass moisture, and wear very well.

Try and stay with natural colors like brown, tan, light green or other natural color. Blue and red are not natural colors!

High Speed CW for COMSEC

I know many of you are saying to yourselves, "Why do we want to use HSCW". Well, the reason is quite simple. It's called "COMSEC", and it is one of the best ways barring actual encipherment to communicate with others within your group.

The reasons are:

1. It is so fast, that unless one is looking for the transmission, all one hears is a "ping".

2. It can be sent under the noise level, so it is very difficult to find the transmission.

3. The message is usually very reliable, and correct.

4. One can send a reasonable message so fast, that unless the other party to the conversation doesn't have time to engage the program before the message is sent and the transmission turned off. This makes good sense especially when one party is under scrutiny by opposition forces.

Take time to search out the programs available for this mode. It will be well worth the time and effort. One downfall is that the "ping" is so fast, that both stations MUST be pretuned. Take some time to learn how to use this tool. It may save your life, or the life of someone important to you.




All you never wanted to know about High-Speed CW MS Operation

WHAT IS HSCW?

HSCW (or HSMS) is the technique of using very high-speed CW Morse code to communicate and exchange of information.

SO JUST HOW FAST IS HSCW? IS IT MUCH FASTER THAN SSB?

Here are some typical examples:


(1 word = 5 letters) [lpm, letters/minute; wpm, words/minute].

Typical CW 25 wpm 125 lpm

Fast CW 50 wpm 250 lpm (Limit of most "regular speed" MS operation)

Fast-talking SSB 100 wpm 500 lpm
Slow HSCW 200 wpm 1000 lpm
Kinda slow HSCW 400 wpm 2000 lpm
Faster HSCW 800 wpm 4000 lpm (common speed)
Still faster HSCW 1200 wpm 6000 lpm
Very fast HSCW 1600 wpm 8000 lpm
Ultra fast HSCW 3200 wpm 16,000 lpm

You can see that even slow HSCW is *much* faster than most SSB operators can talk,except maybe for those whose occupation is auctioneering! And receiver tuning and signal strength requirements are not as tight.

SO JUST HOW SHORT CAN THESE "PINGS" BE AND STILL GET USABLE INFORMATION ACROSS?

Very short! In fact, for HSCW, pings or bursts longer than two or three seconds are exciting but are almost a nuisance! We'll leave it up to you do the actual math. But a 1/10th second ping can propagate a complete set of calls at the medium or higher speeds! This wouldn't even produce a full syllable on SSB!

YOU CAN'T COPY THAT BY EAR! AND THE CW DECODERS I'VE SEEN COULDN'T HANDLE ANYTHING LIKE THIS. HOW DO YOU DO IT?

Right. The idea is simple. Use a device to slow the code down to something readable. Then copy by ear what has come through. Now days we have software programs that are set for HSCW, and make it very easy to encode and decode

SOUNDS TOO SIMPLE.

How do you modify a tape recorder to encode and decode HSMC?


For the past 20 years the European CW operators have been modifying standard audio-cassette recorder motors so that their speed could be varied. This worked well enough for speeds up to about 1500 lpm. Now there are computer programs that will do the same thing much better and at much higher speeds.

SO THE MACHINE DOES ALL THE WORK?

Hardly! It takes the incoming signal, saves it, slows it down, plays it back at a slower speed (and probably heterodynes it to a higher pitch for easier copying). The operator must still do the actual decoding of the signal. The computer or other device slows the speed down, but it is still up to the operator to dig it out of the noise and actually copy it. This is a skill that does not readily lend itself to a machine! While a machine could possibly be built to do this, the technical requirements would be very tight. The brain substitutes for all of this expensive and unavailable equipment!

I HAVE TROUBLE WITH 5 WPM CODE. GUESS THAT LEAVES ME OUT.

Not necessarily. Using CoolEdit, a .WAV file editing program, it is possible to display and read the code visually off the screen. By using MSDSP, you can slow it down by 60 times.

But here's a real, example: Cathy, licensed about 18 years ago, came for a visit. She didn't like code, had only half a dozen CW QSO's as a Novice. Her real interest was emergency/public service work. But seeing HSCW at work here fascinated her. She learned to use MSDSP in 15 minutes and also discovered that she still remembered some of the code. In three schedules, she made three HSCW QSOs (at 5000 lpm - 1000 wpm) because she could slow the code down. Since the signals were often down in the noise, she could also play back a ping a second time to be sure what she had copied. (On her third schedule, she transmitted at 8600 lpm and received at 8500 lpmHOW DO YOU GENERATE CODE AT THAT SPEED? MY KEYER GOES UP TO ONLY 99 WPM.

There are several computer programs that will generate HSCW code. Programs commonly used for transmit-only at HSCW speeds include MSSOFT, CWKey, and PCKEY. MSSOFT can be found on the OH5IY Web site (this program has many other parts besides the transmit portion and is needed for any type of MS operation). This is used by many of the European HSCW operators.

HOW DO YOU KEY THE TRANSMITTER? I DIDN'T THINK RIGS COULD BE KEYED AT THOSE SPEEDS.

Few rigs can be keyed in the standard fashion at much more than 100 wpm (500 lpm); some won't sound good even that fast. The standard practice is to key a pure 2000 Hz audio tone and inject this into the mike jack.

SO IS THIS ACTUALLY SSB PHONE OR MCW OR WHAT?

If properly done, it's CW, but with the zero-beat frequency offset from the dial reading by 2 kHz (with a 2000 Hz tone injected into the mike jack). Recall that on SSB, a single tone simply gives a steady, pure carrier output. Key this tone and you have a CW signal! In fact, this is the way a number of older SSB transmitters generated a CW signal! (By the way, this is actually designated as J2A emission).


HOW LONG HAS HSCW BEEN AROUND? I HAVEN'T HEARD MUCH ABOUT IT BEFORE.

It actually started clear back in the 1950s. They would transmit at higher speeds, record bursts onto reel-to-reel audio tape, then slow it down for playback. This was limited to a maximum of only a 2-times speed reduction, however (or 4 times, for those who had a 15-ips machine). This was too cumbersome and never caught on. Then about two decades ago the Europeans pioneered the technique of modifying the motor speed controller of a cheap audio cassette recorder. Because of the availability of SSB, this never was done much in North America. But in 1997, with the appearance of several computer programs that would emulate and go far beyond the capability of the modified audio recorders, HSCW suddenly surged into prominence.

WHAT KIND OF RIG AND COMPUTER DO I NEED FOR ALL THIS?

The equipment is much the same as needed for any other type of VHF DX operation. If you can operate SSB MS, aurora, or tropo DX, you probably have enough radio equipment for HSCW MS. A common setup would be a multi-mode two-meter transceiver, 150-watt amplifier, and medium-size horizontal beam. (All DX operation on VHF is done with horizontal polarization). Of course, more power is helpful. But HSCW has been successfully done with less than 10 watts into a medium-size Yagi at each end!

For the computer, a '386 or better with the usual peripherals should work. However, all of the software available at this time does require Sound Blaster audio board.

SO HOW MUCH DOES IT COST TO GET ON HSCW?

Like most other aspects of Amateur Radio, this depends upon what you presently have. If you are capable of operating MS, aurora, etc., you probably have a rig that is suitable for HSCW. Nearly all Hams have a computer, and many use it in their routine operations. The one critical piece of equipment at this time is a Creative Labs Sound Blaster stereo audio board or it's equivalent. Most (all?) DSP programs of all types (and there are a number) utilize the Sound Blaster audio board for the conversion. The current HSCW programs are either freeware or shareware.

HOW DO I SLOW DOWN THE CODE TO A USABLE SPEED?

For twenty years the Europeans have been modifying cassette audio recorders. This works OK for up to about 1200-1500 lpm. (This would appear to be a simple, inexpensive method of receiving HSCW, but the conversion can be difficult on some cassette players. And you are limited to a maximum speed of about 1200 lpm. But it has worked for many years in Europe. If you have a computer, this is the recommended method at this time.

How to Set a Trotline


Trotlines have as many as 25 hooks.

Trot lines are a productive tool for catching large numbers of fish at one time. The device consists of one main line, and shorter, hooked lines tied to the main. River sets are most common for trot lines, which are stretched from shore and submerged in the water. Trot lines are most commonly used to target catfish, but are effective with any species of fish.

Difficulty:
Moderate

Instructions
Things You'll Need

Trot line
Weight
Floats
Bait

1

Find a suitable spot in a river to set the trotline. Catfish habitat in rivers includes holes, log jams, submerged brush and undercut banks.
2

Secure one end of the trot line on the riverbank. A tree, heavy weights, concrete blocks or a pole driven into the ground are viable options. The anchor object must be heavy enough to withstand the pressure of multiple fish thrashing about at the same time. Tie the end of the trot line to the anchor object.
3

Motor out from the spot on the bank from which you anchored the trot line; allow the the trot line to play out as you move. Bait each hook as you come to it. Nightcrawlers, shad or cut minnows are effective on trot-line hooks.
4

Tie a float -- an empty milk jug works well -- to a piece of line. Attach the float line to your main line; attach it about one-quarter of the way between the bank and the end of the main line. The float line should be long enough to suspend the hooks 1 or 2 feet off the river's bottom.
5

Motor across the river until you have dropped the floats and all the baited hooks. Attach an anchor to the end of the trot line using a 2-foot piece of rope. Cinder blocks -- or 1-gallon buckets filled with concrete -- make good anchors.
