22 Radio Receiver Projects for the Evil Genius was created to inspire readers both young and old to build and enjoy radio and receiver projects, and perhaps propel interested experimenters into a career in radio, electronics or research. This book is for people who are interested in radio and electronics and those who enjoy building and experimenting as well as those who enjoy research.
Electromagnetic energy encompasses an extremely wide frequency range. Radio frequency energy, both natural radio energy created by lightning and planetary storms as well as radio frequencies generated by man for communications, entertainment, radar, and television are the topic of this chapter.
Radio frequency energy, or RF energy, covers the frequency range from the low end of the radio spectrum, around l0 to 25 kHz, which is used by high-power Navy stations that communicate with submerged nuclear submarines, through the familiar AM broadcast band from 550 to 1600 kHz. Next on the radio frequency spectrum are the shortwave bands from 2000 kHz to 30,000 kHz. The next band of frequencies are the very high frequency television channels covering 54 to 2l6 MHz, through the very popular frequency modulation FM band from 88 to l08 MHz. Following the FM broadcast band are aircraft frequencies on up through UHF television channels and then up through the radar frequency band of 1000 to 1500 MHz, and extending through approximately 300 gHz. See frequency spectrum chart in Figure 1-1. The radio frequency spectrum actually extends almost up to the lower limit of visible light frequencies.
