WAVES AND PROPAGATION: PART 1
Radio and wireless are all about waves and how they link distant points together. Learn about RF propagation, which is the way radio signals get from Point A to Point B. One key element of ham radio is propagation — the way radio signals get from Point A to Point B. Lots of projects involve wireless links, so it behooves the builder to have a bit of an idea about how propagation works. After all, with so many choices available, you need information to understand your requirements for choosing the right technology and installing it properly. We'll start with some basics of radio waves, then get them bouncing around. |

DAVID SARNOFF AND THE BIRTH OF THE AM RADIO
Sarnoff was one of the pioneers of the era of mass communications.
Sarnoff would take radio out of the exclusive province of the transportation industry and embryonic ham radio hobbyists, and put it into every American home. There it would share space with the other appliances that the inventors of the early 20th century were delivering to increasing numbers of consumers. His stubborn pursuit of technology turned his employer, Radio Corp. of America, into a powerhouse in less than a decade. Sarnoff was one of the pioneers of the era of mass communications, transforming America from a nation of local newspapers and pamphleteers into an era where brute technological force allowed a handful of networks of, first, radio stations to flourish, and then television, to create a near-uniform electronic mass media. |
