How Does FM Radio Work?


All sound energy is in the form of a wave. The frequency of a wave is the measurement of the number of cycles that it undergoes in a given time frame. Hertz is a measurement of frequency that depicts the number of wave cycles per second. FM signals are measured in megahertz so an FM signal of 97.5 relates to 97,500,000 waves/second

Frequency Modulation:


  • FM actually stands for Frequency Modulation. FM signals use various frequency levels that reproduce the sound of the originating source (i.e. music). You've probably noticed that FM contains all your music channels while AM radio is limited to news and talk programming. This is because frequency modulation allows for the transmission of the greater range of frequencies (high and low sounds) contained within music

Transmission:


  • FM radio originates at the broadcast source (radio stations). These stations use large antennas to send out their broadcast signal. Electrical charges are pushed up and down the broadcast antenna at a rate that relates to the carrier frequency. The movement of electrical charges creates an electromagnetic field which sends out
  • electromagnetic waves. The waves are sent in all directions. Carrier waves are sent out at a frequency that can be detected by your antenna (the radio station number). They carry sound information that includes the different frequencies of the original broadcast

Reception:


  • The electromagnetic carrier wave travels through the atmosphere until it is picked up by a receiver antenna (i.e. your car radio antenna). At this time the wave causes electrical charges to be pushed up and down your antenna and on into your receiver. The receiver decodes the modulated frequency information and then passes it to the speakers

Processing and Hearing:


  • The speaker vibrates according to the processed frequencies and pushes air molecules that recreate the original sound waves and pass them to your ears. You hear the music or talk that was sent in the original broadcast. Since electricity works at the speed of light, this process, from broadcast to listener, is instantaneous

Loss of Signal:


  • You've probably noticed, particularly if you listen to FM radio in the car, that eventually you will lose your signal. The simple reason for this is that the short wavelength of FM radio waves cause them to travel in straight lines. The earth, however, is curved. Therefore, as the earth curves, FM waves continue in a straight line into the atmosphere and are no longer receptible. The short waves are also affected by obstacles like mountains

How to Strengthen FM Radio Reception?


If you're familiar with fixing your TV's reception, you'll be a natural with an FM radio. FM reception is affected by the same things that affect television signal reception--the quality of your antenna, the strength of the signal you're trying to receive, and any obstacles between your antenna and the transmitte

  • If you don't have an antenna connected to your FM receiver, purchase a simple dipole antenna--a simple T-shape flexible wire-- and connect it to the FM antenna inputs on the receiver. Because FM signals are directional, you'll want to experiment with the positioning of the wire to find the best reception of the station you're trying to receive
  • If you're still not getting a good signal, try an indoor amplified antenna, which you'll find at an electronics store. Don't buy one unless you get a guarantee that you can return it for full credit if it doesn't solve your reception problems
  • If your signal is weak because you live a long way from the transmitter, install an outside antenna and mount it as high as is practical. If you're primarily interested in getting signals from one station or from a group of stations in one direction, get a directional antenna and point it toward the transmitters
  • If you're using a portable FM radio where the only antenna is the power cord, stretch the cord as straight as possible and experiment with positioning again
  • Temporarily switch to monaural mode to improve a weak signal on an FM receiver
