Which distress frequency is known for use in the VHF band?

The distress frequency known for use in the VHF band is 156.800 MHz. This frequency is specifically designated as the international distress frequency for maritime communications. It is part of the VHF marine band and is used by vessels and coastal stations to communicate emergencies.

The importance of 156.800 MHz lies in its global recognition and usage as a distress calling frequency, primarily for ships at sea. When a vessel is in distress, operators are trained to transmit on this frequency to alert nearby vessels and coast guards. This standardization ensures that distress calls can be effectively heard and responded to, enhancing safety at sea.

In contrast, the other frequencies mentioned are not used as the standard distress frequency in the VHF band. 156.600 MHz and 157.000 MHz may be allocated for other specific maritime communications, while 158.000 MHz is typically used for different communication purposes and is not recognized as a distress frequency. Thus, 156.800 MHz stands out as the correct choice due to its established role in emergency maritime communication.
