What does an AM FM tuner do?
Modern radio tuners use a superheterodyne receiver with tuning selected by adjustment of the frequency of a local oscillator. This system shifts the radio frequency of interest to a fixed frequency so that it can be tuned with fixed-frequency band-pass filter.
How do you start a FM radio station?
Here’s how to start a non-internet radio station.
- Apply for a frequency. It may take a long time before you’re assigned a frequency [source FCC].

The best thing for the rest of us to do is to use (or re-purpose) a TV antenna that’s already on your roof. If you still use it to receive off-air TV, then get an inexpensive TV-FM splitter. Or if you’ve switched to cable-TV or satellite-TV, then just connect your old TV connection to your FM radio.
How does AM and FM work?
FM radio works the same way that AM radio works. The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. FM signals have a great advantage over AM signals.
How does FM tuner work?
The job of a tuner is to separate one sine wave from the thousands of radio signals that the antenna receives. Tuners work using a principle called resonance. That is, tuners resonate at, and amplify, one particular frequency and ignore all the other frequencies in the air.
