Hi friends,
can someone please provide me a circuit diagram for a FM transmitter (88Mhz-108Mhz) having range of atleast 5 miles. This is just for experimental purpose.
Thanks,

With best regards,
Amit

I think transmitting signals with enough power to cover this range is illegal.

Check the your country rules.

Depending where you are, a quick search gave the following results. It is best to go for a synthesized unit/kit to prevent frequency drift.

If the link does not work, I searched http://vivisimo.com for "synthesized fm transmitter"

Also like previously suggested, check your laws about transmitting on the 88-108MHz band.

vectronics.com sell VEC1202K kit which uses mc2833. Online manual has the schematic and working details.
