Ham Radio Information

The most common hobby name given to amateur radio is ham radio, which is a big part of the international communications as a complex system. The participants to the communication media enjoy the activity in itself while also doing services to the community, but it is also true that it is on their skills that emergency and disaster communications often rely if necessary. Estimations evaluate a six million people involvement in ham radio, and although they are not broadcasting to make money, the profit comes from the joy of being on air. It is the non-commercial feature the one to distinguish ham radio from other radio stations, and not the lack of skills as one may believe.

Ham radio is believed to go back to the end of the 19th century particularly since at the beginning of the 20th there were around ninety amateur stations registered only in the United States and Canada. The appearance of ham radio is tributary to hobby practices and experiments, and very often the contribution made to science and public services has been preponderant. Moreover, plenty of emergency cases had a happy end because of the intervention of ham radio operators.

Ham radio covers several types of transmissions and besides the quality FM (frequency modulation) that we are all familiar with, ham radio operators also work on single sideband with a higher transmission reliability or on the Morse code even if technology has come a long way since the days of the radio-telegraph. Presently, computers have changed the evolution of ham radio for ever, with the introduction of the digital modes and the development of the packet radio. Last but not least, ham radio operators manage to use the low power communications on shortwave bands to stay in real-time mode.

Ham radio through satellite signal is no longer out of reach with the existence of the orbiting satellites carrying amateur radio (OSCAR); all one needs is a basic hand-held transceiver to make the broadcast possible. What it is very interesting is that many ham radio operators use the aurora borealis and the moon for the reflection of the radio waves. Some ham radio stations have even got into contact with the International Space Station as the astronauts on board are also licensed as amateur radio operators. On-air talks are frequent as many individuals use ham radio only to communicate with other enthusiasts.
