Which channel and mode should be used when initiating a Distress alert transmission?
AI Explanation
The correct answer is C) Channel 70 DSC.
When initiating a Distress alert transmission, the proper channel and mode to use is Channel 70 DSC (Digital Selective Calling). This is the internationally designated DSC Distress and Safety channel, as per the International Convention for the Safety of Life at Sea (SOLAS) and the Federal Communications Commission (FCC) regulations.
The other options are incorrect because: A) Channel 13 and 16 are not the proper channels for initiating a Distress alert; B) Channel 6 DSC is not the designated Distress channel; and D) Channel 6 Radiotelephony is also not the correct channel for a Distress alert transmission.
