Excellent guidance / advice. My radio which is mainly on the FM bands loses reception fairly quickly and as it does so there is a lot of crackle interference. I suspect the antenna's earth connection and your could be worth a check too. I read on here some time ago about this very thing.In order to suppress such interference, the first job is to track down where it's coming from; alternator, another motor, ignition circuits or even more strangely, something like tyre "noise" (yes it does exist although it's almost unheard of these days).
Only once the noise source has been identified can suppression begin.
The first question must be what does it sound like and does it change with engine revs and so on.
Over to you.
Where is the aerial earth point ?
