What emission must be used when operating on the MF distress and calling voice frequency?

Explanation:
On the MF distress and calling voice frequency you use single-sideband telephony with a full carrier. This mode carries voice efficiently, using far less bandwidth than traditional AM, which is essential on the busy MF band. Having the carrier present aids reliable demodulation, especially for weak or long-distance signals typical of distress or calling situations. So for voice on MF distress/calling, the appropriate emission is J3E.
