What is the difference between FM and AM radio stations?
The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.
What means AM and FM?
AM (amplitude modulation) and FM (frequency modulation) are types of modulation (coding). The sound of the program material, usually coming from a radio studio, is used to modulate (vary) a carrier wave of a specific frequency, then broadcast.

Is AM or FM Better?
“FM, which stands for Frequency Modulation, has better sound quality due to higher bandwidth. Also, the way the audio is encoded for FM makes it less sensitive to interference from electrical activity from storms or electrical devices than AM.
Which travels farther AM or FM?
Each FM station is allocated 150 kHz of bandwidth, which is 15 times that of an AM station. This means that an FM station can transmit 15 times as much information as an AM station and explains why music sounds so much better on FM.
HOW FAR CAN AM signals travel?
Useful daytime AM service is generally limited to a radius of no more than about 100 miles (162 km), even for the most powerful stations. However, during nighttime hours the AM signals can travel over hundreds of miles by reflection from the ionosphere, a phenomenon called “skywave” propagation.

Why is AM radio so bad?
AM stands for Amplitude Modulation and has poorer sound quality compared with FM, but it is cheaper to transmit and can be sent over long distances — especially at night. The lower frequencies of the band we use for AM signals creates a wavelength that is extremely large.
Why is AM reception so bad?
The main problem affecting AM signals is electrical interference. Also, the bouncing pattern causes AM signals to fade under bridges or in tunnels. The high-frequency FM signal is limited to a smaller reception radius, around 50 miles.
What are the differences between AM and FM radio?
The basic difference between AM and FM radio is contained in their names; AM stands for amplitude modulation while FM stands for frequency modulation. The way in which radio waves are manipulated to produce sounds in a radio creates differences which affect the quality of the signal. Both types…
