In Chapter 6, career in radio, electronics or research. This book we will discover how FM radio works and how to is for people who are interested in radio and build an FM radio with an SCA output for electronics and those who enjoy building and commercial free radio broadcasts. experimenting as well as those who enjoy research. Chapter 7 will present the exciting world of Radio encompasses many different avenues for shortwave radio. Shortwave radio listening has a enthusiasts to explore, from simple crystal radios to large following and encompasses an entire hobby sophisticated radio telescopes. This book is an in itself. You will be able to hear shortwave attempt to show electronics and radio enthusiasts that stations from around the world, including China, there is a whole new world “out there” to explore. Russia, Italy, on your new shortwave broadcast Chapter 1 will present the history and receiver. Old time radio buffs will be interested in background and elements of radio, such as the single tube Doerle super-regenerative modulation techniques, etc. Chapter 2 will help the shortwave radio. newcomers to electronics, identifying components If you are interested in a portable shortwave and how to look and understand schematics vs. receiver that you could take on a camping trip, pictorial diagrams. Next, Chapter 3 will show the then you may want to construct the multi-band readers how to install electronic components onto integrated circuit shortwave radio receiver circuit boards and how to correctly solder before described in Chapter 8. embarking on their new radio building adventure. If you are interested in Amateur Radio or are We will start our adventure with the simple thinking of learning Morse code or want to “lowly” crystal radio in Chapter 4. Generally increase your code speed, you may want to crystal radios are only thought of as simple AM consider building this 80 and 40-meter code radios which can only pickup local broadcast receiver. This small lightweight portable receiver stations. But did you know that you can build can be built in a small enclosure and taken on crystal radios which can pickup long-distance camping trips, etc. stations as well as FM and shortwave broadcasts In Chapter 10, you will learn how to build and from around the world? You will learn how to use a WWW time code receiver, which can be used build an AM, FM and shortwave crystal radio, in to pick up time signal broadcast from the National this chapter.
