🔍 Key Concepts

• Single Sideband (SSB) HF/MF marine frequencies used for long‑range voice communication • How the U.S. Coast Guard handles follow‑up coordination after a distress call on a primary calling frequency • Which MF/SSB frequencies in the 2–3 MHz range are designated as U.S. Coast Guard working channels rather than initial distress/calling channels

💭 Think About

• Think about which frequency is commonly used by the Coast Guard as a follow‑up working channel after they first hear your distress on a primary distress/calling frequency such as 2182 kHz or via DSC. • Consider which of these options appears on standard MF/HF SSB frequency lists as a Coast Guard channel for continued traffic, not the initial distress alert. • Ask yourself: if 2182 kHz is the classic voice distress frequency, which nearby MF/SSB frequency do many radios and Coast Guard lists pair with it as the normal operating/working frequency for SAR coordination?

✅ Before You Answer

• Check typical MF/HF marine SSB frequency tables for which exact kHz value is labeled as a U.S. Coast Guard working channel. • Verify which of the choices is actually published in U.S. Coast Guard communications guidance as a standard ship‑to‑shore working frequency. • Make sure the option you pick is one that real marine SSB sets commonly program as a Coast Guard working/traffic channel, not just any random value in the 2 MHz band.
