Frequency Range Chart. The radio spectrum refers to the section of the electromagnetic spectrum that holds all possible radio frequencies ranging from 3 kHz to 300 GHz.Radio frequency is used for radio communication technology, wireless networks and telecommunication systems.he radio spectrum refers to the section of the electromagnetic spectrum that holds all possible radio frequencies ranging from 3 kHz to 300 GHz.

A frequency generator produces radio waves. When programmed or adapted for medical purposes, it produces precise waveforms that are square and gated. That means the frequencies start and stop in a rapid staccato rhythm.o approximate Rifeâs equipment, a frequency generator should run a range between 0 and two million hertz. Some specialized amplifiers have doubled or tripled the range, I have used some of these prototypes and they seem to work pretty well.
