wireless transmitter and receiver circuits? Answered

Hi all, can anyone help me, I am trying to create a FM transmitter and receiver unit (two way) to clip into the speakers in a rowing boat to allow me to coach effectively without having to shout or use a megaphone. I have no idea about how to design circuits, but I can build them. Would love all advice. Thanks Carl

i'm not sure exactly how, but look at bmlbytes's transmitter radio tutorials for the transmitter, and just use a really cheap pocket radio from walmart or a pocket radio from Radioshack for the receiver, if the radio doesn't have an audio out jack, open the radio and find the places where the audio signals are sent out to the speaker and use those as audio out
