Show & Tell the Ham Way

Hi Everybody, Frank here.

As some of you are probably aware, I've been teaching a ham radio and survival communications class to some of the folks from my local, small town community. This has really been a fun time. It's caused me to dig a little deeper about radio information than I normally do, and it's given me the opportunity, when I didn't have a clue what the answer was, to refine my lying skills. Just kidding, of course. Kinda.


This is a group of adults, with one 16 year old young adult, two ladies and about 15 men. It's also a very diverse group with various occupations and perspectives about life. But one thing that most of us agree with in this group is that something is coming that is not necessarily going to be good. And that is interesting, because most of the people in this class I did not know before it started.


But back to the story. Last Tuesday evening I got to do show and tell. If you've forgotten what show and tell is, it's that major event when little kids bring something from home to school and talk about it. You know, show and tell. Well, I brought my little Jeep Liberty loaded down with assorted radio toys. My Jeep already has three antennas permanently mounted on it. One of them is the AM/FM radio antenna which gets very little use. Another one is a four foot CB antenna and the other one is a 40" VHF/UHF antenna. The last two are mounted on the rear of the vehicle where the hatch opens, on opposite sides.


I disconnected my CB and my VHF/UHF radios in the car, then rerouted the coax to the back of the vehicle, and used these two antennas during show and tell. But, I need power for these radios, so I took about a 10' piece of 14/2 speaker wire, put a power pole connector on each end, connected one end inside the vehicle to the power source where the original two radios were connected. I routed that power extension out the open hatch in the back. Now we have power at the rear of the vehicle, a CB antenna and a VHF/UHF antenna.


I borrowed a little individual student desk from the church hall where we've been holding our classes, and set up an HF radio and a VHF/UHF radio on this little desk. But I didn't want to use my CB antenna because it is rather limited. As part of the show and tell demonstration, I removed the 48" CB antenna and replaced it with the world famous 102" stainless steel whip antenna. This is the antenna that all others are judged by. The 102 is the one that the really cool cowboys have on their pick up trucks with their CB radios, and now, I was really cool, too. Why the 102? It's by far the best mobile CB antenna made, not the most expensive, but the best performing. So why doesn't everybody use it, you ask? Pray tell, not everyone can handle being cool. Or, maybe realistically, it's because it's 102" long, and it just doesn't fit in everybody's garage door. But the primary reason I used it is because CB is actually the 11 meter HF band, which is right between the 10 and 12 meter bands. With a good tuner, you can tune down to the 20 and 40 meter bands.


Well, we listened for a while on some of the HF bands, and we also listened to some shortwave frequencies. The radio we used to do this with is an ICOM IC-718 accompanied with a LDG IT-100 tuner. I purchased this radio used a couple of days earlier, cleaned it up, reprogrammed it, made some modifications and now it's ready to go. It's a no frills radio with solid performance. The LDG tuner is an excellent compliment to the radio.

Is the 102 the perfect antenna? It is for the CB bands, and it met the needs that evening for show and tell. But you ask, what about the
other radio? Well, the other radio was a VHF/UHF, commonly called a dual band radio. It was connected to the same power supply that ran from the front to the back of the vehicle. It was connected to my mobile antenna that I use everyday, which is a Comet CA 2x4 SR. It's not your everyday ham radio antenna, but it works great on the ham frequencies, and it also works great on the search and rescue frequencies which is what the SR stands for. The radio I was using is the same type I use everyday in my vehicle, but I didn't want to disconnect it, so I used my back up storage radio, which is also and Anytone AT-5888UV. It is not a ham radio, it is a commercial radio that works fine on the ham frequencies and the search and rescue frequencies. We did make contacts with a couple of outside stations and it was fun.

On hand that evening I also brought a VHF/UHF magnet mount antenna. This is the antenna that Fern and I first used on our vehicles. It's a good solid mobile antenna that is also made by Comet, model M-24. Due to time restraints, I did not hook up this antenna, but I did bring a hand held Wouxun dual band VHF/UHF and showed the group how you can connect this radio to the external antenna with an adapter, using what is called a 
battery eliminator that plugs into a cigar plug or power port. With a good microphone attached, and a little Velcro, you now have a solid performing, mobile, 5 watt, VHF/UHF, commercial radio that works on the ham bands, and also the search and rescue frequencies. This is the set up that Fern and I used when we started getting serious about longer distance communication. This set up worked quite well and it would still work quite well. For under $100 one can have an outside the vehicle antenna, which is a must for reliable distance communications, a radio, power supply, and Wa-la! you have communications. There are thousands of ham radio operators that use this type of set up for VHF/UHF. If you get the inclination, you can disconnect the radio from the outside antenna, remove the battery eliminator, insert the original battery, attach the original antenna, and you can now take your hand held radio for a walk. Life is good.


The overall demonstration that night went well. Sitting in a classroom and talking about something is one thing, but seeing it right there in front of you is the best teacher. I'm happy to say that show and tell went well. If some of the language in this article seems a little foreign to you, may I recommend you scoot over to the right hand side of this blog, and up toward the top you will find Frank's Radio Communications. Inside Frank's Radio Communications you will find many articles about radio communications. Some are about ham radio, but there are also articles about CB, GMRS, scanners, shortwave and other radio articles in general.

Ladies and gentlemen, teaching this class has been lots of fun. It's been very eye opening. If you want to learn how to communicate, you can do it too. Here in the near future you might want to have a different way to communicate besides what you depend on today. There is thunder just over the horizon. I would like to be able to quote Ronald Regan, but I can't, so I will paraphrase him. When the man from the government shows up at your door and says he is here to help, turn around and run. Ladies and gentlemen, that man is at the door. Don't get on the bus.

We'll talk more later, Frank

Radios - CB Export/10 Meter - A Re-Post

Hi Everybody, Frank here.

Summertime has certainly come to this part of Oklahoma. It's hot, it's humid, and it's time to be outside. I wanted to share this re-post with you, as it's one of the most popular articles under Frank's Radio Communications. It's a good reminder of the different uses of CB type radios. If you're not paying attention to what's going on in the world, then you seriously need to start looking. Now is the time to upgrade your communication gear. Please go back and read some of the other radio posts. If you've got food stored, and you've got your beans, bandaids and bullets, then it's seriously time to think about some form of communication. If you would, read this re-post, and you need to get your act together. Take care.

We'll talk more later, Frank

Hello, Frank here.

I would like to tell you about a CB radio that is not really a CB, but it can be. I don't understand exactly why these are made or sold, but I would assume it has to do with profit. There is going to be some new jargon on this post, so like always, if you don't understand everything, wait a little while and it will soak in. 

Export radios, to the best of my knowledge, are what they say they are. These radios are meant to be sold outside of this country - exports. Other countries use different bands and frequencies for their radio communications. Therefore, these radios are easy to modify and can be used for the frequencies and bands in this country as well. Some export radios are programmable via computer which makes it easy to add the CB frequencies. Another option is power capabilities up to 100 watts, 200 watts and more. These radios also tend to be more expensive. Are they legal to use on the CB frequencies? The answer is no. Do people use them on the CB frequencies? The answer is yes. Some of the previous sites I have posted sell export radios. If this is what you are looking for you will probably never have any problems with the FCC unless you are interfering with other forms of transmission. 

10 meter radios are similar in nature to export radios. Almost everything I said above applies to 10 meter radios. Let me explain the difference. A 10 meter radio operates on the amateur radio frequencies or ham radio. You have to have an amateur radio license to use the radio on 10 meters. I will talk more about amateur radio licensing and frequencies in a future post. Okay. Follow me here now. Some of the ham bands are 10 meter, 12 meter, 15 meter and so forth. The CB radio frequencies fall between the 10 and 12 meter ham bands. CB is often called 11 meters. Meters have to do with the length of the frequency signal. But at this time, that is not important. It will be discussed more later.


So. You can buy a 10 meter radio with a small modification or you can program in the CB frequencies with the computer program option if it is available. Let's clarify something here. A ham radio license does not allow the ham radio operator to operate on 11 meters because CB radios are approved by the FCC to operate on CB frequencies only. Is it legal to operate a 10 meter radio on CB frequencies? The answer is no. Do people use 10 meter radios for CB purposes? The answer is yes. These same dealers mentioned above also carry some of the 10 meter radios. It's a matter of driving 56 MPH in a 55 MPH zone and driving 95 MPH in a 55 MPH zone. Both are illegal, one will attract a whole lot more attention than the other. 

Can you mount these radios in your car or truck? Sure, you can. If the radio runs higher power, it will come with the appropriate size
power cable. If you need to extend this cable to your battery, use the same size cable or larger. In most cases, you can use the same antenna as any CB radio, unless you are running an exorbitant amount of power. In that case you need to make sure your antenna will handle the power. If you need to tune these, you can do it yourself or you can take it to your local CB shop and they can tune your rig for you.

If you are giving thought to purchasing one of these types of radios, please get one with SSB. Remember, some, but not all of these radios can be used for 10 meter ham radio operation.

If you choose to use this type of radio for a base station, your one amp power supply will not work. A quick review here: P = E x I. P = power or watts, E = voltage, and I = current or amps. Let's say you are running 200 watts of power. That is your P. Your voltage will be 13.8, that is E. That is 200 divided by 13.8, equals 14.5 amps or I. Don't forget the rule of 80. This means you will need at least 18 amps just to run this radio. That's why on the last post it was recommended that you purchase a 30 amp power supply for your home. 

There is something I failed to mention on the last CB post. You cannot take your base station and outside antenna to a CB shop and have it tuned so you will need to do it yourself, or have a competent friend help you. This will involve an SWR meter, and a three foot jumper, which is a short piece of coax with a 259 connector on each end which allows you to put the meter in line between the radio and the antenna. This will allow you to tune your SWR down. Read the FAQ at this site. It will answer most of your questions about SWR. Again, make sure your base station antenna can handle the power you are using. Don't push any antenna to the maximum, use the rule of 80.

If you can, ground your radio. The radio may or may not have a ground plug on the back, most CB's don't. If it doesn't, slide in a piece of flexible, coated, copper wire about size 12-14, where you attach the screws to mount the radio. This will give you a good, solid ground. In your car, find a screw somewhere connected to metal. In your house, run the ground wire back the same way you brought in your antenna wire and attach it to the three foot copper rod that you placed in the earth. Do you have to ground your radio? No. Will it help clean up some sound issues? Yes. When we talk about ham radios, grounding will be covered in greater detail.

By the way, if you choose to get your ham radio license, you can use these radios to operate on 10 or 12 meter frequencies. Just a little bonus there if you decide to make that switch. 

I know all of this information about the CB radios, export radios and 10 meter radios is a general and broad view. I would encourage you to read some of the earlier posts about laws, regulations, safety, and some of the websites that have FAQ sections about radios and antennas. There is a lot of information about CB radios that is not included here. In future posts we'll be talking in more detail about power supplies, antennas, coaxial cables, connectors, ham radios, GMRS, FRS and commercial radios.

What I have to say now is a personal observation. The reason I got into radio communications is because someday there may not be the regular types of communications that we have now. When I say regular, I am talking about cell phones, hard-line phones, internet, television, AM/FM radio, etc. A lot of people currently have CB
radios. Some folks approve of the type of traffic on them and some don't. But if there is a nationwide emergency, CB radios and GMRS will be excellent forms of communication. Most people don't realize that the two-way communication radios that they have right now are of an excellent quality and can be used during an emergency. Of course, I hope this day never comes. But I believe that the wolf is at the door. I would recommend all families have some type of communications, whether it is two-way or listening only. We will talk more about receive only radios - how to power them with things such as rechargeable batteries, small solar panels or car batteries. This is all part of communications. 

This finishes up my posts on CB's for now, more will come later. Next I am going to talk about GMRS, FRS, and MURS. 

We'll talk more later. 73, Frank
