8 This bookis for people who are interested in Radio andelectronics and those who enjoy building andexperimenting as well as those who enjoy encompasses many different avenues forenthusiasts to explore, from simple crystal radios tosophisticated Radio telescopes. This book is anattempt to show electronics and Radio enthusiasts thatthere is a whole new world out there to 1 will present the history andbackground and elements of Radio , such asmodulation techniques, etc. Chapter 2 will help thenewcomers to electronics, identifying componentsand how to look and understand schematics diagrams. Next, Chapter 3 will show thereaders how to install electronic components ontocircuit boards and how to correctly solder beforeembarking on their new Radio building will start our adventure with the simple lowly crystal Radio in Chapter 4.

9 Generallycrystal radios are only thought of as simple AMradios which can only pickup local broadcaststations. But did you know that you can buildcrystal radios which can pickup long-distancestations as well as FM and shortwave broadcastsfrom around the world? You will learn how tobuild an AM, FM and shortwave crystal Radio , inthis Chapter 5, you will learn how AM Radio isbroadcast, from a Radio station to a Receiver in yourhome, and how to build your own TRF or TunedRadio Frequency AM Radio Receiver . In Chapter 6,we will discover how FM Radio works and how tobuild an FM Radio with an SCA output forcommercial free Radio 7 will present the exciting world ofshortwave Radio . Shortwave Radio listening has alarge following and encompasses an entire hobbyin itself. You will be able to hear shortwavestations from around the world, including China,Russia, Italy, on your new shortwave broadcastreceiver.

10 Old time Radio buffs will be interested inthe single tube Doerle super-regenerativeshortwave you are interested in a portable shortwavereceiver that you could take on a camping trip,then you may want to construct the multi-bandintegrated circuit shortwave Radio receiverdescribed in Chapter you are interested in Amateur Radio or arethinking of learning Morse code or want toincrease your code speed, you may want toconsider building this 80 and 40-meter codereceiver. This small lightweight portable receivercan be built in a small enclosure and taken oncamping trips, Chapter 10, you will learn how to build anduse a WWW time code Receiver , which can be usedto pick up time signal broadcast from the NationalInstitute of Standards and Technology (NIST) orCopyright 2008 by The McGraw-Hill Companies, Inc.
