Which frequency is most commonly used for distress communications across the globe?

The frequency most commonly used for distress communications across the globe is 156.800 MHz, designated as Channel 16 in marine VHF radio communication. This channel serves as the international distress, urgency, and calling frequency for maritime purposes. It is utilized by vessels in need of assistance or in emergency situations to communicate quickly and effectively.

One of the key reasons this frequency is preferred is its global standardization, ensuring that mariners worldwide are educated to monitor and respond on this channel. This high level of awareness significantly increases the chances of a timely and effective response to distress signals.

Additionally, Channel 16 is monitored by the coast guard and other rescue authorities, allowing for immediate support and coordination in emergency scenarios. This is crucial in ensuring safety at sea, as rapid and accurate communication can make the difference in life-saving situations.

Other frequencies listed, while they may serve specific functions, are not primarily designated for international distress communications and thus do not have the same level of recognition and response capability as Channel 16.
