What is the HF DSC receive frequency?

• A. 2187.5 kHz
• B. 2185.8 kHz
• C. 2182 kHz
• D. 2196 kHz

Answer: (A)

DSC on MF/HF relies on a dedicated receive frequency for automated calls and distress signals. The standard HF DSC receive frequency is 2187.5 kHz, globally allocated for distress alerts and calling under the GMDSS. Monitoring this frequency lets you hear incoming DSC messages from other ships or coast stations, and you follow DSC procedures to respond on the proper transmit channel. The other frequencies aren’t the recognized global MF/HF DSC receive channel, so they wouldn’t reliably capture standard DSC calls.
