What is the calling and distress frequency on a single side band (SSB) marine radiotelephone?

A 1492 kHz
B 1892 kHz
C 2082 kHz
D 2182 kHz
AI Explanation

The correct answer is D) 2182 kHz. The 2182 kHz frequency is the international calling and distress frequency for single sideband (SSB) marine radiotelephones. This frequency is designated for emergency communications, and it is the frequency that vessels are required to monitor when underway. The other answer choices are incorrect because they do not correspond to the established calling and distress frequency for SSB marine radiotelephones. Vessels are required to be able to transmit and receive on 2182 kHz in order to participate in the global maritime distress and safety system (GMDSS).
