General Radio MW settings

[jamx2]

Recently my radio has had a lot of interference on the MW channels while the engine is switched on and while I am driving you can hardly here the radio for the buzzing sound, once engine is switched off the channels are perfect, any ideas how to solve this?

well your getting interference for sure.
could try a suppresor on the alterntor or as i would do run a power feed directly from the battery and earth the stereo to the bodywork.
obviously disconnecting the OE wiring
