hi any one have AM radio emeter (simple) project or shematic and ducumentation for LPC ,processor thinks
Yes, a lot of people have managed to find low-power FM transmitters suitable for transmitting MP3 music to a car radio or similar.
FM transmitters powerful enough to span a farm would most probably be illegal all around the industrialized world, since such a transmitter would interfere with official broadcasts.
I have to assume your post to be a bit of a joke, since any 100mA power consumption or total port drive current or whatever is completely irrelevant to the power of an FM transmitter. A uC doesn't have the speed to modulate data at the normal FM radio frequencies...
