I'm hoping somebody may be able to point me in the right direction.
My parents A3 has the symphony stereo and when listening to AM (Radio 5) the reception is terrable. It crackles and buzzes and breaks up, although it is fine on FM stations.
I have checked that the aerial cable is actually physically plugged in to the back of the radio and all seems good.
We have check the aerial base on the roof and it appears to have some electronics in it, could this be the problem? Not sure if this is relevant or not but there is also a junction box on top of the sub, is this a diversity unit? Is there a seperate aerial for AM to FM?
Hoping somebody can help.
