Good day
I want to build a FM Radio Transmitter unit that can be interfaced with a pic to send a beep or something to a standard FM Radio on a specific frequency.
Can anyone point me in the right direction.

Hi,
You won’t be able to cover an entire hemisphere but it's a starting point.

(Some models can transmit on any FM frequency from 87.5 to 108.0).
Best regards,

Hi,
Quickest way would be to buy one of these Ipod/MP3 FM transmitter units. They are crystal controlled (PLL) with a choice of preset frequency. Connect pic to audio plug and get it to generate a bleep with a few resistors and capacitors to shape the waveform.
I have seen these FM transmitter units for £4 inc postage.
