Coast Guard to Install Radio-Activated Sound Signals in Connecticut and Long Island

NEW HAVEN, Conn. – Coast Guard Sector Long Island Sound will be replacing traditional sound signals (foghorns) with marine radio-activated sound signals at eight different locations across Connecticut and three locations on Long Island.

Mariners that require the use of sound signals during periods of reduced visibility will be able to activate them on demand by momentarily turning their VHF-FM radio to channel 83A/157.175Mhz and key their microphone five times consecutively. This will activate the sound signal for up to 60 minutes. The current sound signal type and characteristic will not change due to this conversion. All light characteristics, equipment and patterns will also remain unchanged.
