Frequency modulation is the main principle behind FM radio broadcasting. It has been invented by American electrical engineer Edwin Armstrong nearly 33 years ago to transmit high quality sound over regular radio internet channels. Since then, the technology has become much more widespread, and the majority of countries have access to FM broadcasting in one form or another. It has recently become possible for ordinary consumers to purchase and operate their own portable FM transmitter or antenna, so that they can listen on FM wherever they go.
The principal advantages of Frequency Modulation are its efficiency and simplicity, and its wide range. As we have already noted, the principle behind the transmission of FM is frequency modulation, and this is why it is so popular. Because it requires no large antenna or transceiver, amateur radio operators are able to receive and transmit without any significant additional equipment. There is nothing complicated or expensive needed in order to start the operation. There is also no need for any kind of license, which opens the door to a whole new audience.
Many people in the world today listen to amateur radio as a hobby, and many of these people would love to experience the same benefits of having their very own portable FM transmitter/antenna for much less money than it would cost to purchase and install a full set-up. Amateur radio operators all over the world have discovered the beauty and excitement of Frequency Modulation and, through experimentation, have found great ways to make it work best in their individual circumstances. When you find the right FMS (frequency modulation) solution for you and your particular situation, you will immediately see the benefits not only for yourself but also for others. Before you know it, you'll be the talk of the town!
