The standard emergency radio transmits on which channel(s)?

VHF channel 16 is designated as the international distress, safety, and calling frequency. It is used for emergency communications and is monitored by all vessels and coast stations, making it crucial for distress situations. Channel 6 is often used for inter-ship communications, especially for safety-related messaging.

Transmitting on these channels ensures that emergency transmissions are likely to be received promptly by nearby vessels or by coast stations that are listening in for emergency calls. The combination of channels 16 and 6 thus serves a critical function in emergency communication protocols on the water.

The other channels mentioned in the incorrect options are either not designated for emergency communications or are not recognized for specific distress uses under Standard Operating Procedures. Therefore, the selection of VHF channel 16 along with channel 6 stands out as the correct choice for standard emergency radio transmissions.
