After receiving your distress call, the U.S.C.G. may ask you to switch to which SSB frequency?

Correct Answer: Option B — 2670

Frequency 2670 kHz (2.670 MHz) is designated by the U.S. Coast Guard as the primary inter-ship and ship-to-shore radiotelephone working frequency for distress, safety, and operational coordination following initial contact on 2182 kHz.
