What is the correct response after a false distress alert is sent an 8 MHz frequency?

The correct response to a false distress alert initiated on an 8 MHz frequency involves the established procedures for cancelling such alerts. When a false distress alert is sent, the appropriate course of action is to issue a cancellation message via the same frequency the alert was originally sent. This effectively informs all stations monitoring that the distress alert was sent in error.

The option to make a call on 8291.0 kHz refers to a specific frequency used for maritime communication, which would be an appropriate means to communicate concerning the false alert. However, directly addressing the alert on the same frequency would usually be more effective as it ensures that the cancellation reaches the intended audience.

Cancelling a false distress alert cannot be properly done by using "MAYDAY," as that term specifically indicates an emergency. This term is reserved for genuine distress situations and using it for cancelling a false alert could create further confusion among other maritime operators.

While using all TELEX channels or communicating through Inmarsat could be utilized for additional communication needs or routine operational messages, they do not directly address the immediate need to cancel the false alert effectively and promptly as required by maritime communication protocols.

In summary, the action required to properly and promptly handle a false distress alert on an 8 MHz frequency is
