In Car Mp3 FM Transmitter

[Dusty Bin]

I've been given an in car MP3 FM transmiiiter so I can play songs on my mp3 player through my car stereo but I've hit a problem.

The instructions leaflet tells me that I must find a free FM frequency or one with a weak signal.

How do I find a free FM frequency?

I can find a few with weak signals but there's a great deal of interference on these which means the song is playing there but I can hardly hear it for all the crackling noise!

I tune mine into 107.7 - 107.9 Mhz . Its quiet at this end of the freq band.

Thank you.

I'll try that.

Cheers!
