- | When radio first appeared, the signal had to be manually adjusted for optimal reception. During the mid-twentieth century, Automatic Frequency Control (AFC), also called Automatic Fine Tuning (AFT), was introduced allowing the radio circuitry to automatically keep a resonant circuit tuned to the frequency of an incoming radio signal. It was primarily used in radio receivers to keep the receiver tuned to the frequency of the desired station. | + | When radios |
