how to pinpoint the location of a broadcasted-radio transmission?

Question

I was able to listen to a "pirate" radio station(on the last frequency of the FM dial) and wants to pinpoint its location.

Answer 1

A loop antenna will give you a bearing line. - Plot it.
Move to a different location, take another bearing.
Plot it as well.
Where the lines cross on the map......

Answer 2

you need to know the power of the signal, then calculate based on the recieve power, your distance (this makes a make believe circle around your location.

then move to a different spot, do the same thing, and make a nother imaginary circle, this gives 2 possible points.

then you need one more and that makes one possible point.

i don't think you have the right equipment to do this so w/e, goodluck.
