Contents
Chapter 1 will present the history and background and elements of radio, such as modulation techniques, etc.Chapter 2 will help the newcomers to electronics, identifying components and how to look and understand schematics vs. pictorial diagrams.
Chapter 3 will show the readers how to install electronic components onto circuit boards and how to correctly solder before embarking on their new radio building adventure.
Chapter 4 Generally crystal radios are only thought of as simple AM radios which can only pick up local broadcast stations. But did you know that you can build crystal radios which can pick up long-distance stations as well as FM and shortwave broadcasts from around the world? You will learn how to build an AM, FM, and shortwave crystal radio, in this chapter.
Chapter 5, you will learn how AM radio is broadcast, from a radio station to a receiver in your home, and how to build your own TRF or Tuned Radio Frequency AM radio receiver.
Chapter 6, we will discover how FM radio works and how to build an FM radio with an SCA output for commercial-free radio broadcasts.
Chapter 7 will present the exciting world of shortwave radio. Shortwave radio listening has a
large following and encompasses an entire hobby in itself. You will be able to hear shortwave stations from around the world, including China, Russia, Italy, on your new shortwave broadcast receiver. Old-time radio buffs will be interested in the single tube Doerle super-regenerative shortwave radio.
Chapter 8,If you are interested in a portable shortwave receiver that you could take on a camping trip, then you may want to construct the multi-band integrated circuit shortwave radio receiver
Chapter 9, If you are interested in Amateur Radio or are thinking of learning Morse code or want to increase your code speed, you may want to consider building this 80 and 40-meter code receiver. This small lightweight portable receiver can be built in a small enclosure and taken on camping trips, etc.
Chapter 10, you will learn how to build and use a WWW time code receiver, which can be used to pick up time signal broadcast from the National Institute of Standards and Technology (NIST) or National Atomic Time Clock in Boulder CO. Time signal broadcasts present geophysical and propagation forecasts as well as marine and sea conditions. They will also help you set the time on your best chronometer.

Time signal broadcasts present geophysical and propagation forecasts as well as marine and sea conditions. They will also help you set the time on your best chronometer.
Chapter 11, you will discover the high frequency “action bands” which cover the police, fire, taxis, highway departments, and marine frequencies. You will be able to listen to all the exciting communications in your hometown.
Chapter 12 will permit to the discovery of the interesting hobby of Amateur Radio. The 6-meter and 2-meter ham radio bands are two of the most popular VHF bands for technician class licensees. You may discover that you might just want to get your own ham radio license and talk to ham radio operators through local VHF repeaters or to the rest of the world.
Chapter 13, Why not build an aircraft radio and listen in to airline pilots talking from 747s to the control tower many miles away. You could also build the passive Air-band radio which you use to listen in to your pilot during your own flight. Passive aircraft radios will not interfere with airborne radio so they are permitted on airplanes, without restriction. Check out these two receivers
Chapter 14 will also show you how to build an induction communication system, which will allow
you to broadcast a signal around home or office using a loop of wire, to a special induction receiver. The induction loop broadcast system is a great aid to the hearing impaired since it can broadcast to hearing aids as well.
Chapter 15, will pick up very very low-frequency radio waves from around the world. You will be able to listen to low-frequency beacon stations, submarine transmissions, and “whistlers” or the radio waves created from electrical storms on the other side of the globe. This project is great for research projects where you can record and later analyze,
Chapter 16, will permit you to “see” the approaching storm before it actually arrives. This receiver will permit you to have an advanced warning up to 50 miles or more away; it will warn you well in advance of an electrical storm, so you can disconnect any outdoor antennas.
Chapter 17, will allow to you pick up a broad spectrum of radio waves that get converted to DC power, and which can be used to power low current circuits around your home or office. This is a great project for experimentation and research. You can use it to charge cell phones, emergency lights, etc.
Chapter 18 can be used to see the diurnal or daily changes in the Earth’s magnetic field, and you can record the result to a data-logger or recording multi-meter.
Chapter 19. A SIDs receiver can be used to determine when radio signals and/or propagation is disturbed by solar storms. This receiver will quickly alert you to unfavorable radio conditions. You can collect the receiver to your personal computer’s sound card and use the data recorded to correlate radio propagation against storm conditions.

Chapter 20 will alert you, with both sound and meter display, when the Earth’s magnetic increases just before an Aurora display is about to take place. UFO and Alien contact buffs can use this receiver to know when UFOs are close by.
Chapter 21, can be utilized for detecting low-frequency waves generated by earthquakes and fault lines. With this receiver, you will be able to conduct your own research projects on monitoring the pulse of the Earth. You can connect your ELF receiver to a data logger and record the signals over time to correlate your research with that of others.
Chapter 22, will pick up radio signals which indicate electrical and or magnetic storms on the Jovian planet. The Radio Jupiter receiver can be coupled to your personal computer and can be used for a research project to record and analyze these radio storm signals.
Chapter 23. This receiver will allow you to receive APT polar satellites broadcasting while passing overhead. You can display the satellite weather maps on the computer’s screen or save them later to show friends and relatives.
Chapter 24 discusses different analog to digital converters which you can use to collect and record data from the different receiver projects.
