Transmitter

I was wondering how to make a spy bug. I would use an arduino fm transmitter module and an Arduino Nano. I wanted it to be small, compact and to run on a 9V battery. I was also wondering how to make a receiver with an arduino UNO.

Do not double post.

I won't now that I how reliable the form is.

a/ why would you need a processor to do this?
b/ why ask an open forum for help on an illegal device?
