From a microvolt in the air to music in the room. Amplification is the quiet miracle at the heart of electronics: a whisper of a signal goes in, and a faithful, larger copy comes out. Amplifier Theory explains that miracle from first principles — twice. Once through the glowing vacuum tube, once through the cold silicon of the transistor — and then shows them to be two dialects of a single language: a controlled valve with a load line drawn across its curves. Starting with nothing more than the idea of gain, the book builds the decibel, the load line, and the resonant tuned circuit; ...

Clergymen rarely make good politicians. There is perhaps no better example of this than Father Charles Coughlin, a Depression-era priest-turned-demagogue who was seen as an angel by some and a devil by others. The same man who cruelly castigated the Jews also spoke eloquently on the needs and rights of the most downtrodden in society. The same orator who said, "Roosevelt or ruin", later cried, "Roosevelt and ruin." In the 1930s, his effective use of the radio revolutionized mass communications, and millions of people listened to his every word.

Most amateur radio stations fail before the signal ever leaves the antenna. You can have good SWR. You can run more power. You can follow popular antenna designs. And still be weak, inconsistent, or unreadable. If you’re tired of guessing, this book was written for you. If you have ever wondered why an antenna that should work doesn’t, this book explains the exact reasons. Ham Radio Signal Behavior shows what radio waves actually do once they leave the wire—and why small changes in height, geometry, or ground interaction can completely transform performance. This is not an exam-prep ...

The Radio Right tells the story of the 1960s far right, who were frustrated by what they perceived to be liberal bias in the national media, particularly the media's sycophantic relationship with the John F. Kennedy administration. By the early 1960s, millions of Americans listened each week to conservative broadcasters, the most prominent of which were clergy or lay broadcasters from across the religious spectrum, including Carl McIntire, Billy James Hargis, and Clarence Manion.
