Those FM transmitters you used to use to get music from your iPod on to your car stereo? Full-fledged radio transmitters, just ones with severely limited outputs to avoid violating any FCC laws. But the easiest and cheapest option is a Raspberry Pi. The same principles apply: use the tiny computer to create and broadcast the signal, and attach an antenna to give it the broadcast range. Once you remove the idea of pirate radio from its mythology, you realize that it exists largely for people who live in the margins.
This special series of features and podcasts explores a complicated narrative of what illegal transmissions can do and who they reach. Get your tracks set and copy them over to the Raspberry Pi.
Depending on your setup and surrounding environment, the Pi can broadcast between about a foot to roughly feet away.

Use the given schematic to create the circuit. It is always a good idea to wire up the components on a breadboard before moving the circuit over to a perfboard. Here you can find the vector graphics I made for my own case.
Feel free to use them to mill your own one or print them out and use them as a template. After your case is complete it is time to mount all your other external components and main perfboard inside it.
Hello, 5 buttons to add the user wants to memorize the frequencies will be much better. Or turn off the radio and start the last listened frequency. Can you do? Reply 5 months ago. Reply 1 year ago. Question 1 year ago on Introduction.
Got it mostly working, but for some reason it is constantly switching between modes freq and volume I've tried different Arduinos and various hardware debounce techniques.
Any ideas? Reply 4 years ago. Got it figured out When powered via wall-wart or usb it caused a jumpy mode switch. Powered by battery or my bench supply it's smooth as glass. Reply 2 years ago.

It's illegal to operate an unlicensed radio station, even at extremely low power [source: FCC ]. Establish a source of funding. Remember, you'll need to pay for studio space and power, among other things. Decide if you want to start a low-power or full-power radio station. This includes paying an application fee.
A full-power station will need tens of thousands of watts, while a low-power station may only need a thousand watts. Buy the necessary equipment, including transmitter gear and an antenna. You may need to rent space on a tower for your antenna. Design your studio. You'll need sound proofing, headphones, speakers, microphones and more [source: Community-Media ].
Recruit broadcasters. Make sure you have enough people to fill up all the time slots. Have your broadcasters practice doing shows for a few weeks before going on the air. They'll need to get comfortable with the microphone and develop their technical skills. Work all the kinks out of your program schedule.

I think they have to be "BF" labelled transistors, these are designed to work at radio frequencies. However if you can't find BF transistors in your country it may be because they are labelled differently.
This circuit diagram makes little-to-no sense and the out of focus pictures don't help. The parts list is inaccurate and does not clearly list the supplies needed. For example you have not listed the voltage or type IE: Ceramic Capacitor vs regular capacitor. I know this is an old project, but if you could would you possible upload an updated PCB board diagram and 'adjust' the parts list.
Also, could you please post the whole info on the required parts, for instance when looking for a capacitor there are multiple specs, like voltage and other stuff that I don't understand.
