Raspberry PIrate Radio
(electronicsforu.com) Using a readymade disk image and one simple solder connection, turn
your Raspberry Pi into a streaming pirate radio.
NOTE: The Raspberry Pi's broadcast frequency can range between 1Mhz and
250Mhz, which may interfere with government bands. We advise that you
limit your transmissions to the standard FM band of 87.5MHz--108.0MHz
and always choose a frequency that's not already in use, to avoid
interference with licensed broadcasters.
