Which statement about Channel 70 is true?

Explanation:
Channel 70 is set aside for Digital Select Calling on VHF, meaning its sole purpose is to transmit digital call signals to other stations using MMSI numbers. It isn’t used for voice communications, weather broadcasts, or casual chat. If a DSC call on Channel 70 succeeds in reaching the other station, you would typically switch to a voice channel to carry the actual conversation. For context, Channel 16 is the traditional hailing and distress channel, and after establishing contact via DSC, you move to an appropriate working voice channel to talk.
