On September 5, 1977 NASA launched the Voyager 1 space probe from Cape Canaveral to study the outer Solar System. The little guy just kept on going into interstellar space, still transmitting out of its twelve foot dish antenna, blissfully unaware that QRP doesn’t work. Well, Voyager cheated a little, I do too sometimes, by using twenty three Watts of power, still almost 538 million miles per Watt. Imagine waiting more than thirty seven and a half hour to get a reply to your CQ! Sure, Earth has big ears, but let’s not tarnish NASA’s golden record; pun intended.

Back down to Earth, are we? Some amateurs use levels of power that if not your head, will make your electricity meter spin. How much power do we need? The FCC says as little as possible to make a decent contact. Some play with micro-Watts and get through; millions of miles per Watt. Transceiver manufacturers seem to have settled on one hundred Watts, a number most likely based on marketing and economical factors rather than real life applications. One hundred is a nice round number. I am a big fan of QRP, or rather, ultra-portable radios, usually five to ten Watts. My friend Ray and I used to experiment with reduced power down to one hundred milliwatts over more than eight hundred miles; CW of course. Why signal with a flashlight when you can use a laser pointer? I was making regular contacts to Eastern Europe from Florida using from one to five Watts to about six thousand miles. Power is expensive, in dollars, Amperes and kilograms.

The military figured it out long ago. They deal with life-and-death communications from the field, portable man-pack operations in HF, which is still in use, just not the only option anymore. My RT-320 outputs about twenty five Watts, as do most military portable transceivers.

Power does help, nobody can deny it. There is however the law of diminishing returns. When the ionosphere isn’t cooperating no amount of power will get through. When it does, you don’t need much to be heard. A good resonant antenna and some knowledge will go a long way. I bet inadequate antennas radiating only a few Watts rather than the hundred coming out of the transceiver are the norm rather than the exception.

I suggest any new Hams to save their money, study antenna designs and spend an afternoon at the hardware store. Amplifiers are mostly used for contests where the goal is not to make contact but crush the competition. Better chase losses, hunt for noise sources, use better aerials and more efficient modes like CW or PSK-31.

I believe the magic numbers are five Watts CW and twenty five Watts SSB. You can go on a nice DXpedition for the price of an amplifier. If someone doesn’t believe how well they hear your five Watts, tell them the story of the little probe that could.

We’re all supposed to get along right? Sharing the same space, in this case amateur radio bands, in an atmosphere of respect and friendship… Until a contest is on. A Ham contest, for those who don’t know about them, is a weird hobby, a bit like train or plane spotting. People get on the air and make as many contacts as possible over a week-end. A contact lasts only a few seconds, just an exchange of call signs, and that’s it. There is no conversation taking place. There is no human interraction, so to speak. If that was all there was to it, it would be fine. People do what they want, it’s none of my business. Until their hobby is infringing on mine that is. Infringing in this case is too light a word. Until it obliterates mine for a whole week-end that is. They do this regularly.

Contesters think absolutely everyone loves contests and participates. So they park themelves on calling frequencies regularly used for low-power operations and call every few seconds for hours-on-end using hundreds of Watts, trampling on every other signal. It’s a contest, a free-for-all Roman arena, and damned be anyone who want to chat with their friends or make new ones using a respectful few Watts of power. They drool over their microphones or Morse key with bloodshot eyes. They need those points to win a new plaque or certificate for their trophy room. If the Ham radio contest was a touring rally, they’d run pedestrians over with their cars.

You would think contest organizers would police, or at least educate their members, but no. Because contest organizers are also contesters. The biggest culprit is the ARRL. Their station, W1AW monopolizes QRP (low-power) calling frequencies for hours with incessant calling using high power, and damned be anybody else. They to this all the time outside contests. How could we expect them to police contests? They even broadcast their Morse code practice daily on multiple bands. While I think that is actually useful, although I wish they used classic books instead of technical articles, it is against the law. But the ARRL is above that. Why should they worry about mere mortal radio operators using little home-built radios not manufactured by their corporate sponsors?

Contesters will also say that non-participants can go the the WARC bands, 30, 17 and 12m. Well, not everyone has those or an antenna to accomodate them. Don’t piss on me and tell me it’s raining. Why don’t we have one contesting band and you guys can all go to it where you won’t bother everybody else? How does that sound? They also say contesting is the Godsent gift to Ham radio. As if amateur radio would collapse without them. I don’t think so. I was also told “if you can’t beat them, join them.” Nope, not going to happen. Just like I wouldn’t sit outside an airport writing down airplane tail numbers all day or go to a cross-dressing furry swinger’s party… Not my cup of tea, although I’d choose the furry party over a Ham contest any day. To me, contests are pointless and weird, and that’s it, so no, I won’t participate, I’d rather watch paint dry.

Bottom line is, when a contest is on, way too often, I might as well go fishing or something, because turning my itty-bitty radio on is as productive as pissing in a violin. The lack of respect is appaling. There isn’t a wide enough stretch of frequency left free of pollution for long enough for me to contact, let alone chat with anyone.

You want to enjoy your contesting hobby? Fine with me. Just don’t keep me out of mine to enjoy yours.

I don’t mean don’t become a Ham! Amateur Radio is a great hobby and asset in emergency situations. Most newcomers go for the first and easiest license, Technician. I think it is a mistake. Technician privileges suck, excuse my French. They allow access mainly to VHF and UHF bands which depending on location can be pretty boring. Most new Ham’s first contact will be signing into a “net.” They’ll give their call-sign, get a welcome, and that is it. After that, maybe a few conversations about nothing. The first time I listened to the 2m band I heard some guy explaining how he had fixed his toilet.. Except for the occasional gem, it hasn’t gotten much better than that. Newbies buy a handheld with its little stubby antenna and get disappointed, of course.. Many will quit right then. There is more to amateur radio than a Tech license and a walkie talkie.

When I suggest to someone that they should give Ham radio a try, I always insist that they go for the General license, at least. While the Technician license allows the use of a few small portions of HF bands for Morse code and a bit of SSB voice on 10m, few take advantage of it. The General license however opens the door to a vast section of HF, which means global coverage even with the simplest radio. General isn’t difficult. With just a little bit more studying, anyone who can pass the Tech exam should pass General. The “Extra” license is harder, but still reachable by most. I passed all three in one session, so can you. Take your time and study hard, it’s worth the effort.


We’ll start with local communications. Failure of land lines and cell phone relays could isolate you from family members and friends you would want on your side in an emergency. After a hurricane a few miles might as well be a few thousand. Something might also happen while you are away from home, if only shopping on the other side of town. I hope you have a bug-out bag in your car to help you get home…

Before diving into the subject, I need to lay out some bases on frequencies and communication modes. It isn’t hard to understand and I will do my best to make it as simple as possible. Take your local radio station for instance.. Let’s say you listen to 102.5 FM. 102.5 is the frequency, in this case 102.5 megahertz, which is 102,500,000 cycles per second. Frequencies are measured in Hertz, meaning cycles per second. Imagine flipping the light switch in your kitchen.. At 102.5MHz you would be flipping it more than a hundred million times per second. Pretty easy concept. As far as units go, we use the Hertz, Kilohertz (x1000 Hertz), Megahertz (x1,000,000 Hertz) and Gigahertz (1,000,000,000 Hertz). You are already familiar with “Gigahertz” if you ever had to shop for a computer…

FM is the modulation mode, which means the way your voice (or data) is coded before sending it by radio waves. I won’t get into details here but just know that there are different modes. You probably listen to AM radio sometimes, which is a different voice mode from FM. AM (amplitude modulation) was invented before FM (frequency modulation) and is of course still in use today by short-wave radio stations because it is more efficient than FM. AM will go further than FM using the same power but doesn’t sound as clear. This is why radio stations prefer FM for music. For local communications you will be using AM or FM, but on different frequencies than your local radio stations.

So, why use different frequencies and which ones are useful to you? For practical matters, we will divide frequencies in two parts: HF or High Frequency, and VHF/UHF or Very High Frequency and Ultra High Frequency. HF, as far as Ham radio is concerned goes from about 1600KHz to 30MHz. UHF goes up to a few Gigahertz. So, your local FM radio station uses VHF which is above 30MHz but below about 400MHz, and your AM station uses HF, around 1MHz. What’s the difference? You see, the problem with radio is that the earth is round but radio waves travel in straight lines… So how do you contact someone who is beyond line-of-sight? If it wasn’t for the ionosphere, we would never have been able to do so before the invention of the communications satellite. There would have been no Titanic survivors! Fortunately radio waves bounce on the ionosphere! Under certain circumstances… They can even bounce on the earth and go all around the world! The ionosphere will bounce radio waves up to around 50MHz, and not very often at that frequency. It depends on solar activity. That’s why you’ll never hear an FM radio station from Japan! But you might hear an AM one on HF if you have a big enough antenna.

For local communications everyone uses VHF and UHF, except for CB radios which use HF on 27MHz. We can use HF for local communications as well as VHF/UHF but we run into another problem, antenna size… The length of any antenna depends on the frequency. You can’t use any antenna size… It is inversely proportional to the frequency used. Antennas are usually half a wavelength. Take 7MHz for instance, which is a popular Ham HF frequency.. The size of a half-wave antenna is around 66ft. A bit long for a handheld radio! Another common Ham band for local communications is the 2 meter band around 146MHz. A half-wave antenna for that frequency is about 3.2ft. Now we can slap that on a walkie-talkie.. You will learn about all that simple math while studying for your Ham Technician license.

Let’s look at the no-license-required options for local comms: You probably already own a pair of FRS handheld radios. You can find them at Walmart for as low as $30. How good are they? Pretty good it turns out, but their range is limited. The manufacturers pretend up to twenty or thirty miles, but that would be floating in space talking to someone on the ground. The earth being round, again, we run into the line-of-sight-problem. Two humans standing up with a radio at head-height will only be able to talk to about six miles… That goes for any radio at that height, FRS or not. Because of their low power and small antennas, actual range is more like two miles maximum. A good way to extend range would be to climb on your roof, but obstructions will reduce the practical range and you’ll never get more than a few miles. FRS (family radio service) radios are more useful to keep in touch while moving as a group in case some members get separated.

An alternative to FRS handhelds are MURS radios. They aren’t much different but since less people know about them you get a little more privacy… Anyone can listen to FRS. Few people use MURS because they cost a bit more. Range is similar to FRS in that they are limited by the same laws of physics.

Personally I don’t have much money to spend on gear so I opted for FRS. If things turn ugly I can give a few to my friends and establish a simple code for operational security. I highly suggest that you do buy as many as you need for each members of you inner circle, plus a couple spares.

Then we have the good old CB radios. They operate in AM on 27MHz. Furthermore, you get forty channels. Since this is HF, it is occasionally possible to communicate over vast distances using a CB (citizen band) radio, although the FCC doesn’t allow you to talk to anyone beyond 250 miles. I don’t think they enforce it… There are very few CB handhelds as most models are for car or home use. Antennas are fairly long, not very practical for something you might want top carry in your pocket. It is however a popular band to listen to, though if you have kids I’d suggest keeping them away from it! CB used to be civil and polite, self policing. Not any more… If you decide to buy a CB I suggest you get one with SSB modes, which we will talk about in our upcoming long distance communications article. See my post about the Galaxy DX-979. Getting a CB means that you will have to learn a bit about antenna tuning and how to measure SWR (standing wave ratio), which is how much power is not radiated by the antenna and could fry your radio turning it into a receiver only.. It is simple but can’t be ignored. Your antenna must be of a precise specific length to transmit with. So, if you buy a CB radio, also buy a SWR meter. More about that in our HF article later.

Ham radio is you best choice for emergency communications. Not only the radios are of better quality and more versatile but you also gain a whole community of knowledgeable individuals ready to help you. The Technician exam is so easy it’s almost laughable. It will only set you back about $15 and your license will be valid for ten years. The FCC assigns you a call sign and that’s the extent of it. You gain access to many frequencies and modes for worldwide communications. The Technician license is mostly for local communications but allows some long-range contacts on some bands.

The most common local Ham band is 2m FM, which covers from 144 to 148MHz. What’s so great about it compared to say, FRS, since again the laws of physics come into play? In one word, repeaters! Ham operators install repeaters on high towers all over the country. You can be pretty sure there is one within range of your house. These repeaters relay your signal over large distances, sometimes up to one or two hundred miles. Not bad for using a small handheld radio. Repeaters might not operate for long after a large scale emergency but at least they will keep you connected until the generators run out of gas.

Another popular band like 2m is the 70cm band from 420 to 450MHz. Most handheld radios offer both band in one device which is what I suggest you get. Prices range from $35 to $600 but you can get a great radio for $150. Ignore expensive digital models because they don’t work any better than the good old FM ones. More private maybe, but that’s about it.

One of my favorite model is the Yaesu FT-270. It is a 2m only model, very rugged and waterproof. You can actually dunk the darn thing in a bucket of water while it’s on and it will keep working! Best thing is, price is around $120. Another cheap option is the Chinese Baofeng UV-5R and UV-5R+ models. They have both 2m and 70cm and can be programmed to include FRS and MURS channels, though you can legally only listen. In an emergency however, you can use any radio on any frequency, so a good option to have. The UV-5R has a big flaw however and that is the external microphone jack. It breaks after you use it a few times, limiting you to use the radio with an external microphone only. I have two and both are broken. One I received already broken and the other one broke within a couple weeks. I now use them with external microphones.. Still a good deal for $50 a pop. If you get one I suggest never plugging in an external microphone and using it as-is. That way it will last a very long time. It’s too bad a great radio like this was built with sub-standard jacks.

Get your Ham radio license! Go to the ARRL site to find an exam session and buy a book. Then open a free account on They have free practice exams online. If you are local to Sarasota, contact me and I will answer any question you might have. If you are hesitating because you fear being put on some list, let me tell you that you are already on a few and a Ham radio license won’t make any difference. There are no good reasons in my opinion not to get one. I would even suggest trying to pass both the Technician and General exams on the same session. It isn’t much harder and will give you access to a flurry of frequencies on HF.

So far we have our few FRS or MURS handhelds, maybe a CB for the house or car, and a couple 2m/70cm Ham HTs (handi-talkies). What else do we need? We need to know what’s going on beyond our town, even beyond our continent! Everyone needs a short-wave receiver. Short-wave is HF. Something like the Tecsun PL-380 for bout $45. Whatever you buy make sure it has a plug for an external antenna. The built-in antennas are way too small to be of any use. You will plug in a long wire, say 60ft. or more to get distant stations. Also make sure the receiver decodes SSB to listen to Ham radio operators. Usually a good short-wave receiver covers all HF Ham bands and everything else in between. Some Ham radio transceivers (transmitter/receiver) allow you to listen in between Ham bands, thus act as a short-wave receiver. If you plan on getting into Ham radio you might just buy one, even before you get your license, if only to listen. Otherwise, do buy a short-wave receiver!

There you have it, all you need for local communications and getting news from distant stations. How are we going to power it all up without electricity? First, make sure all the devices you buy can be powered with AA batteries.. They are everywhere and rechargeable ones can be recharged with a solar panel like the GoalZero Nomad 7, which I use. You can charge four batteries at a time in about four hours. Make sure you buy AA battery adapters for your HTs and have the correct connectors and battery packs for your other devices.

You need to protect your gear against strong magnetic fields generated by lightning or an EMP. I use a cookie tin can with my radios wrapped in plastic as to not touch the sides of the can.. It isn’t grounded but I hope it would work. I tried placing my cell phone inside then calling it, it didn’t ring. I also soldered a piece of wire between the can and the lid to insure a good electrical contact. I sometimes leave a radio outside the box but never leave it plugged-in while not in use.

Questions and comment are welcome. I will be glad to help anyone get into Ham radio. The next article will cover global communications. Stay tuned!
