What do AM and FM stands for?
AM (Amplitude Modulation) and FM (Frequency Modulation) are types of modulation (coding). The electrical signal from program material, usually coming from a studio, is mixed with a carrier wave of a specific frequency, then broadcast.
What does XM stand for radio?
XM. No Modulation (satellite radio)
Why is FM still used?
It is also less susceptible to common forms of interference, reducing static and popping sounds often heard on AM. Therefore, FM is used for most broadcasts of music or general audio (in the audio spectrum). FM radio stations use the very high frequency range of radio frequencies.
When was FM invented?
Armstrong built the first full-scale FM station in 1939, transmitting to experimental receivers from “a 400-ft. tower on the Hudson River Palisades at Alpine, N.J.”
How was FM invented?
In 1933, FM radio was patented by inventor Edwin H. Armstrong. FM uses frequency modulation of the radio wave to reduce static and interference from electrical equipment and the atmosphere.
What are the best FM radio stations?

What is the full form of FM radio?
What is the full form of FM? – Frequency Modulation – Frequency Modulation (FM) is a method of broadcasting radio signals. In Frequency Modulation, the fr
What are the differences between AM and FM radio?
FM signals are almost strictly line-of-sight — once you drop over the horizon,you lose FM reception.
How do I start a FM radio station?
Decide if you want to start a low-power or full-power radio station.
