How to Build a High Powered FM Amplifier

Frequency modulation is a means by which information is transmitted over a carrier wave. That information can be digital or analog. Radio broadcast is a common frequency modulation application, although the signal is sometimes weak. There are three common reasons why your FM signal is weak: too muc

Electromagnetic waves and radio propagation

Radio signals exist as a form of electromagnetic wave. These radio signals are the same form of radiation as light, ultra-violet, infra-red, etc., differing only in the wavelength or frequency of the radiation. Electromagnetic waves have two elements. They are made from electric and magne

Homemade FM Antennas

Radios and other broadcasting instruments that receive electromagnetic waves from transmitters and convert them into electrical current, and vice versa, use antennas. FM, or frequency modulation, provides superior quality sound signals to the listeners. You can make an efficient and inexpensive ant
