Ray70 Hailer

[Chuck - Raymarine - Moderator]

Kevin,

Thanks for sending the requested photo. The upper station would be exposed to additional volume level from the horn as there is no structure between the horn and the Raymic. While this appears to be a completely normal/acceptable location for the hailer horn relative to each station, it may explain why feedback is not occurring when the Raymic is plugged directly into the Ray70 at the lower station. After replacing the speaker wire, then please respond regarding whether the problem persists. Please additionally indicate the make/model of hailer horn which has been installed onboard.
