    You just need to make an FM transmitter. The receiver can be your a handheld radio or even mobile phone with FM radio.

    I'll be back to you with a link as soon as my internet stabilize.

    the main idea on spying is that the size is very small if you are going for such a long range then i doubt it

    but it is not impossible you may try to use some survey setups to track a area of 100 to 200m

    i can't see other wise

    Try to implement something like repeater to increase range. 😀
