Chris, This subject has already been a topic three years ago on the Forum and so far I remember OM Ahti Aintila from Finland was the first to detect and replace the noisy dc-dc converter with an external power supply. Sorry to see old topics repeatingly coming up all the time while information is available in the archives. Before I used a notebook computer and my moving noise disappeared when pulling the plug of notebooks power supply.
