What does am and FM mean for radio?
In the beginning, radio was a simple technology. Just a few transistors were needed for a small, battery-powered radio in homes and cars. The military also used radio to send and receive messages. But by the 1930s, the United States was developing the technology needed to create a broadcast radio network. This network would allow people to listen to programs from radio stations around the country. The first radio station in the United States began broadcasting in 1926.

What does am and FM mean in radios?
If you listen to the radio, you’ve likely heard talk about the two different ways broadcasters can send sound to your radio. Stereo sound is sent using amplitude modulation (AM) while frequency modulation (FM) is used for mono sound. Stereo sound is sent using two different frequencies that the radio can detect and reproduce. Because there’s only one frequency for mono sound, mono sound is sent using frequency modulation. For the most part, you won’t notice a difference
What does am and FM mean in AM/FM?
“am” and “fm” are the abbreviations for amplitude modulation and frequency modulation, the two main types of radio technology. In an analog radio, the signal is sent as a continuous wave, varying the amplitude (loudness) to represent sound and the frequency to represent pitch. In contrast, in a digital radio, the signal is encoded in a series of 1s and 0s — the “ones” and “zeros” of the digital
