Radio frequency (RF) refers to the rate of oscillation of electromagnetic radio waves in the range of 3 kHz to 300 GHz, as well as the alternating currents carrying the radio signals. This is the frequency band that is used for communications transmission and broadcasting.How are radio frequencies assigned?
Radio frequencies are part of the electromagnetic spectrum. When in the field, participants in a military operations agree to use a given set of frequencies for communication, then encode their transmissions since any party that can tune into that frequency can receive their transmissions. Consumer radios typically feature AM and FM tuners.What is the FM and AM radio frequency range?
AM radio ranges from 535 to 1705 kilohertz, whereas FM radio ranges in a higher spectrum from 88 to 108 megahertz . For AM radio, stations are possible every 10 kHz and FM stations are possible every 200 kHz.
