This is the smallest FM transmitter kit possible using passive components. Great for P.I. or police work. Place this anywhere you’d like to monitor and the sensitive little onboard mic will do the listening for you. You can tune it anywhere between 90 to 94 MHz in the FM band, and then you can find it with a regular FM radio
It is your duty to obey the laws of your country. Some countries do not allow any unlicensed FM Transmitters.
Please use this kit with your best ethical and legal discretion, as it’s designed for education purposes.
