My Fusion AM/FM radio has suffered from 'noise' on the AM band in particular since installation. I finally got around to systematically tracking down the noise sources: turns out to be mainly the Victron inverter/charger, when in charger mode..... and to a lesser degree, the engine room ventilation fans.
The 'noise' shows up via the antenna cable: unplug the antenna, the noise goes away. No noise when the unit is running off an ipod or CD player. I have a dedicated AM/FM antenna, a quality brand installed new in 2009. The antenna cable doesn't run anywhere near the inverter/charger or cabling to the engine room fans. Noise occurs in dock or at anchor, doesn't change.
I have just email'd Victron to see if there's anything I can do at the charger itself to reduce the 'noise'. I'm surprised at the Victron finding, as these units have a good reputation for RFI suppression. I am not hopeful they will be able to suggest anything.
That aside, I can most easily install an in-line noise filter in the antenna line right behind the Fusion unit. I would be very interested to hear what experience others have of these in-line noise suppressors: do they work and if so, what brand/models are recommended?
