F3E emission refers to which type of modulation?

Explanation:
FM is the modulation type here. In emission designators, the first letter shows the modulation, and F means frequency modulation. F3E is the standard designation used for FM voice on marine channels, so it identifies FM voice. If the transmission were AM voice, the designation would start with A; SSB voice uses a designation starting with J; FM data would indicate a data-type emission rather than voice.
