How far will a 1W FM transmitter go?

1 watt will comfortably serve a housing estate and, if decently placed, will reach beyond 1 mile for most radios, though it can sometimes cover exceptionally long distances. 10 watts will comfortably cover up to 3 or 4 miles with good line-of-sight to the transmitter. Any obstructions will reduce that.

Why do FM transmitters sound bad?

The reason behind that type of interference is usually a station that’s so close or so powerful that it bleeds over into nearby frequencies. There might be a nearby station using 88.1 MHz that’s so powerful it creates experience down at 87.9 MHz.

How does a FM transmitter work on a Raspberry Pi?

So by writing a code to perform frequency modulation using the spread-spectrum clock signal we can tweak the Pi to work as a FM transmitter. The modulated signal will be given out through the GPIO pin 4 of the Raspberry Pi.

Where does the signal come from on a Raspberry Pi?

The modulated signal will be given out through the GPIO pin 4 of the Raspberry Pi. We can simply attach a normal wire of 20 cm maximum to this pin to act as an antenna. If you already know how to reach your pi though Terminal window then skip this step, else read through.

How long does it take to set up a Raspberry Pi radio station?

Surprising enough with the help of Raspberry Pi it should hardly take less than half an hour to set up your own FM broadcasting station and get on air within a local area. With the help of a proper antenna you should be able to cover an area of 50m Radius which should be enough to broadcast within your school or locality.
