What's Ham Radio? Amateur Radio What's that?
|Amateur radio is a hobby that has been around almost as long as radio itself. Amateur radio operators, usually referred to as “Hams”, are people with an interest in radio design and communication. More importantly, they provide the community with a vital resource in the event of an emergency or natural disaster.
Hams enjoy operating their own two-way radio station to talk to people all over the world or in their own community. In the early days of radio a century ago this was done using the "dits" and "dahs" of Morse code, but nowadays Hams are more likely to talk into a microphone or use high tech digital techniques.. Hams can be found bouncing signals off the moon, using satellites or using the computer in their hobby. Many Hams simply like to "ragchew", the Ham term for sitting back and having a long conversation with another Ham.
The necessary equipment consists of a transmitter and receiver (or transceiver), an antenna (which can be as simple as a piece of wire), a microphone and/or a Morse code key.
Amateur radio is not only a hobby. Thousands of Hams are involved in essential public service. We provide communications after natural disasters, such as tornadoes, floods or earthquakes, when all the other lines of communications are down. We bring with us our own power generators and equipment so that we are completely independent.
We maintain our emergency equipment in readiness so that we can move to an area in trouble with the minimum of delay. Hams are people of all ages and from all walks of life. We have Hams from nine to ninety.
There are many ways in which Hams communicate. The most popular is using voice transmissions, just as you would over the telephone (without getting a bill at the end of the month!) Increasingly now, Hams use digital modes. The oldest of these is Morse code, which is still used by many Hams.
Traditional modes, such as radiotelegraphy, are still popular but, with the advent of the computer, Hams now use some very sophisticated techniques to get messages to remote parts of the world.
Amateur radio satellites are orbiting the globe and provide another way for Hams to talk to each other. Signals are even bounced of the moon by some Hams.
What is necessary to became a Amateur Radio ?
|Hams are licensed by governments in all countries and have "callsigns" to identify themselves. In French callsigns are F, in Saint Martin FS ,in Spain EA or in Portugal CT .
To become a Ham, first you have to ask for a Amateur Radio Club in your country and after that look for examinations rules in the Comunications Office you have to demonstrate a knowledge of basic electronics and know how to maintain and operate your station in a safe manner. In order to do this, you will have to pass an examination.
There are several ways that you can study for this. If you want to do it on your own, you can use the Amate
