Astra radio interference

As I replied in my other post in which you asked exactly the same question:-

1). Bad earth at the aerial base. There is a nut with a toothed washer which bites into the bodywork to provide a good earth. Sometimes a quick tweak with a spanner is enough to re-establish a good earth. 2). Break in the signal or screen part of the coaxial aerial cable that runs from front to rear. Sometimes, the fault lies in the connector that is used to join the front and rear sections of the loom. This can be overcome by installing a one-piece aerial lead, part no. 90513340. I have fitted many of these leads during my stint as an auto-electrician, and their fitment cures about 95% of all interference problems.

The ultimate cure is to give up listening to medium wave - it will never be perfect, especially in an electrically noisy environment such as a car. Even on a portable stereo, medium wave has loads of static and spurious noise, so why expect a car stereo to be as good as FM?

The sole fact that MW is an outdated transmission band that is so prone to interference it is unreal.

But you can't get Test Match Special on FM! Reason enough to get good AM reception, at least until DAB is universally available.

Thanks Anthony for your suggestions. Vauxhall seem convinced now that I need a new 'Aerial Amplifier' ?? I'll let them go to the bother as it's still under Warranty, and see what they have to suggest when it doesn't cure the fault :-) Phil..
