[CA] [CA11] Fading echo on M92650-S 2KW 18″ domes.

Welcome to the Raymarine Forum Sailing_Sergio,

The reported symptom is commonly associated with component damage resulting from a high voltage spike (ex. such as is commonly encountered with a lightning strike to or in close proximity to the vessel) to the radome's circuity. Such damage would typically be found within the radome's LNC circuitry or IF interface circuitry. Unfortunately, Raymarine can no longer provide parts and service for these radomes. Currently manufactured radomes are not compatible with C-Series Classic MFDs such as yours. Should you be unable to render the repair yourself, it would be necessary to seek a replacement radome from the second hand market or consider replacement of not only the radome, but also the MFD.
