I purchased a radio transmitter for my Zune, and it takes quite a bit of work to get it to function properly. I have not been taught much about how radio waves function or why my transmitter is behaving the way it is, so help me find a solution to my problem! When my radio transmitter (something that's plugged into the audio output jack on my Zune, so I can tune in and listen on my radio) is plugged in, in order for it to work correctly I must hold the transmitter in my hand without touching my Zune. If I don't touch the transmitter, all I hear is static. If I touch the transmitter AND touch the Zune, all I hear is static. Why does this happen, and is there any way to fix it?
