so is it possible to convert it as FM transmitter so that i can receive the transmission over my FM radio.i just want to hack it so that it work as FM transmitter.soon i'll try to post the picture of the TX.
if any one has done this before pls help.

AFIK the frequnecy band of the transmitter is nowhere near the FM broadcast band. To hack it in such a way would probably require changing nearly every component. You'd be better off starting from scratch and building something designed for the job.
