Foundations Of Amateur Radio

Foundations of Amateur Radio Cars have been here for well over a century and so has radio. Cars pretty much start when Carl Benz first applied for a patent for his "vehicle powered by a gas engine" on the 29th of January 1886 which is regarded as the birth certificate for automobiles. Radio starts as a thing when Heinrich Hertz proves that radio waves exist in 1888. Since then things have changed, a lot. Today, both these technologies, cars and radio, are everywhere. It's estimated that there are 1.47 billion vehicles on the planet today, in contrast, there are only 44 thousand broadcasters across the globe, serving about 4 billion people, or half the population. So, cars win, right? Not so fast. The Wi-Fi Alliance estimates that there's 3.8 billion Wi-Fi devices being shipped this year alone and there's about 19.5 billion in use. Many of those are mobile phones, so they're not only using Wi-Fi, but GSM, CDMA, 3G, 4G or 5G radios. In many cases they'll have Bluetooth on board and will be receiving GPS in
