Why are some radio stations stronger than others?

As it turns out, the ionosphere reflects certain frequencies of radio waves. So the waves bounce between the ground and the ionosphere and make their way around the planet. You can pick up some radio stations better at night because the reflection characteristics of the ionosphere are better at night.

How do I get better AM radio reception?

Q: How do I get better AM reception? You can get better AM reception by using an external antenna such as a loop antenna, placing your radio near the window with its rear facing outside, or switching off/moving away any electrical appliances that have been proven to interfere with your radio’s reception.

Why is FM higher quality than AM?

“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.

Why do FM radio stations sound better than AM stations?

This explains why FM stations sound better than AM stations, but AM stations can be heard from further away. AM radio varies the amplitude of the broadcast signal so the power at which that signal is broadcast is also changed, since amplitude represents the strength of the signal. Some receivers can’t pick up low amplitude signals at all.

Which is a distinct advantage that FM has over AM?

A distinct advantage that FM has over AM is that FM radio has better sound quality than AM radio. The disadvantage of FM signal is that it is more local and cannot be transmitted over long distance.

Why do you hear some radio stations better at night?

Why do you hear some radio stations better at night than in the day? Ground-based radio signals are influenced by the ionosphere. Radio waves naturally travel in straight lines, so you would naturally expect (because of the curvature of the earth) that no radio station would transmit farther than 30 or 40 miles.

What are the characteristics and services of FM radio?

FM radio characteristics and services include pre-emphasis and de-emphasis, stereophonic FM sound, Quadraphonic sound, Dolby FM and other subcarrier services. Pre-emphasis and de-emphasis are processes that require boosting and reducing certain frequencies. This is done to reduce noise at high frequencies.
