The Roots Of Radio Hobbyists

Radio hobbyists can play with their equipment all day without giving a thought to the origins of their hobby. Early radio hobbyists were part of something that was, at the time, new and fairly crazy.

After radio technology was stabilized, there was a steady growth of radio signaling in the fields of navigation of ships and for rescue operations. On the other hand, the amateur radio operators also started to dominate the air. The first documented and famous amateur wireless enthusiast was a then young man named Irving Vermilya born in 1890 when wireless transmission was being born. The young man since age 12 heard Marconi and built his own wireless transmission equipment and was often “heard” telegraphing with ships during that time. In 1911 he became a member of the Radio Club that had been formed. He got himself certified in 1912 when law mandated all wireless operators to be certified. In his own words,

This was pre-audio era, and communication was purely in Morse code. Irving then organized his own amateur group who had regular meetings monthly and would communicate daily wishing “GM” (good morning) and “GN” (good night), some of the first amateur jargon to be used. He also proceeds to describe in his series of articles published in QST magazine in 1917 as to how they managed to lay the telegraph lines and such and how they “drew juice” for the wireless operation from the electric lines instead of relying on batteries.

Meanwhile, apart from the “professionals” and “amateurs”, with audio wireless signal transmission there was a new revolution setting in. A Dutch engineer in Hague was the first to make regular wireless transmission via radio. This could be considered the first regular radio broadcast. After this there was slow development until the commercial radio stations came into being.

The requirement to be certified killed the enthusiasm in many amateurs, and the number of amateurs dwindled. But then after WWI, there was a boom. The first radio clubs were formed in 1909 and this was the beginning of the radio hobbies which included radio as a part of the hobby activity.

During the WWI the amateur radio operators were asked to stop their activity and dismantle the equipment. Radio operators in uniform helped in military communications. They got back on the air again by November 1919 again. A similar lull in amateur radio happened during Second World War and got back on air by 1946. After lots of battles over the frequency range that the amateurs can tune into, the amateur radio is here to stay!

At present there are more than 170,000 ham operators which is possibly not the complete picture. It is still increasing. So, with Irving Vermilya was born the amateur radio operation, since he was the first radio hobbyist. After lots of developments, including the discovery of the transistor which greatly decreased the size of the radio equipment, the old ways still remains which included “waiting for someone to signal”.

The rules to get oneself certified and licensed included a Morse code proficiency until the World Radiocommunication Conference in Geneva in 2003 that eliminated the need for Morse code proficiency from the licensure tests. Taking effect from February 23, 2007 the Morse code has been eliminated from the tests for amateur radio license tests.

The Process Of Building A Radio Controlled Plane



People can spend hundreds and hundreds of hours on building a radio controlled plane. It is a hobby that is very pervasive throughout the world, and no matter where you can go you can find at least a few die-hard enthusiasts who will continue to devote their time to creating the best radio controlled plane possible. Some people get started on the project on a whim, without putting proper thought into the amount of effort that it will take to get finished. If you are thinking about making a radio controlled plane, you should know exactly what will be required of you. You may decide that it is too much work for too little payoff – or you may be passionate enough to stick with it and give it a try.

The first, and the longest, part of the process is to build the model. By itself, the model is no more than a bunch of wood, glue, and maybe a bit of metal in the shape of a plane. How much effort you spend on this will be dependent on what your goal is. Do you just want something that will get off the ground? If that’s the case, the style won’t matter too much to you. You can build a very basic box that will be able to lift off. However, most of the time hobbyists will create lifelike representations of existing airplanes. This involves creating an airframe out of a light material such as balsa wood, then covering up the sides with some kind of plastic. The dimensions are usually scale representations of whatever plane the model is based off of.

After the basic model is built, the builder will begin to bring the whole project together by installing the motor and radio components. They should always be easily removable, in case they need to be replaced. Get everything fit in to make sure you created the model correctly. Usually, you will buy all of the motors and radio transmitters in one set, and by following some quick instructions you can get it all pieced together. After you have installed it once to make sure, you should take it all out and finish the details of the model. Add decals, paint it, and do anything else that you have in mind. Once that is done with, put the motor equipment back in one last time.

Unless you have followed directions word for word down to every last detail, your plane probably won’t be ready to fly right away. At this point you can take it out to a field or a park and attempt a takeoff, but you shouldn’t hold your breath. You might have been lucky enough to get it right the first time, but you will probably need to make some tweaks. This is by far the most frustrating part of making a radio controlled plane. You will have to determine whether it is a problem with aerodynamics, or whether your radio equipment simply isn’t working. If you are stuck on this step, it’s a good idea to consult a radio controlled hobby expert to see if you can get a diagnosis.

The process definitely takes a lot of time and a lot of effort, but it is worth it in the end. When you can make a flawless takeoff and maneuver the plane through the air, you will be proud of the work that you have done. While you are toiling over building the model, getting everything to work right, and getting it to take off, just imagine that first moment when you are able to take off. Go out to the park one day, and see if you can catch another model plane enthusiast out flying his or her plane. Take a turn, and get a taste for what is coming in the future. If you keep reminding yourself of that, you will be able to remain inspired.
