I have a Blaupunkt car radio above & I was interested to know how to expand the FM to recieve 104MHz as it should. Currently it will only recieve up to 102.9MHz. 

 The original FM band width was 87-104MHZ. If in recieving up to 104MHZ the radio looses some of the lower band width I'm OK with that.

Many Thanks in advance.
