In this tutorial, we will be showing you the basics of how to setup a Raspberry Pi Pirate Radio utilizing the FM Transmitter software and a piece of wire.
Basically, this piece of software allows you to broadcast a FM signal through your GPIO 4 pin. This means you can setup your own little radio station, however please be noted that the sound quality and range will be quite poor due to the signal been limited to mono and that most wires aren’t the best antennas.
At this point it’s pretty well-known that you can tack a long wire to the Raspberry Pi’s GPIO, install some software, and you’ve got yourself the worlds easiest pirate FM radio station. We say that it’s a “pirate” station because, despite being ridiculously easy to do, broadcasting on these frequencies without a license is illegal. Even if you had a license, the Raspberry Pi with a dangling bit of wire will be spewing out all kinds of unintentional noise, making it a no-go for any legitimate purposes.
In an effort to address that issue, [Naich] has written up a couple posts on his blog which not only discuss why the Pi is such a poor transmitter, but shows how you can build a filter to help improve the situation.
[Naich] then goes on to show how you can build a DIY filter “hat” for the Pi that not only cuts down a lot of the undesirable chatter, but even boosts the intended signal a bit.
