RE: [CA11] interference
Welcome to the Raymarine Forum Jim,

Such interference can occur when VHF communications equipment is installed within 3' of the marine electronics or when VHF antenna cables have been bundled with power, communications, or transducer cables. Should the VHF antenna cable have been installed in this manner, then it would be recommended that it be re-routed. Should the VHF antenna cable have been installed in this manner, then please click here to view a FAQ addressing installation of RF suppression ferrites. A sufficient number of RF suppression ferrites may be installed onto the DSM's power and communications cable to suppress RF emissions from these cables. As indicated within the referenced FAQ, these ferrites should be installed as close as is permissible to the cable's plug.
