\"Radio waves\" transmit music, conversations, pictures and data invisibly through the air, often over millions of miles -- it happens every day in thousands of different ways! Even though radio waves are invisible and completely undetectable to humans, they have totally changed society. Whether we are talking about a cell phone, a baby monitor, a ...
The list goes on and on... Even things like radar and microwave ovens depend on radio waves. Things like communication and navigation satellites would be impossible without radio waves, as would modern aviation -- an airplane depends on a dozen different radio systems. The current trend toward wireless Internet access uses radio as well, and that m...
The funny thing is that, at its core, radio is an incredibly simple technology. With just a couple of electronic components that cost at most a dollar or two, you can build simple radio transmitters and receivers. The story of how something so simple has become a bedrock technology of the modern world is fascinating!
Millions of radio waves--carrying sound wave signals and digital signals--reach your receiver every second. The receiver's tuner picks out a specific signal. Its amplifier strengthens that signal. A demodulator separates the signal from the carrier wave. And then a speaker converts the signal to the sound waves that you hear!
Jan 22, 2024 · Radio waves are produced by an alternating current (AC) in an antenna. When the AC flows through the antenna, it creates oscillating electric and magnetic fields that radiate outwards as radio waves. These waves propagate in all directions from the antenna, making them capable of traveling long distances.

Basic Radio Awareness Introduction to Radio Communications Principles. All forms of communication follow the same basic principles. In this first chapter, we explore those principles and the different ways in which people communicate. We also look at radio waves and learn how radio technology is able to make your voice heard many miles away.
