Monitoring of Certain High Frequency, Voice-Distress Frequencies

Краткое содержание

The U.S. Coast Guard will cease monitoring all High Frequency (HF) voice distress frequencies within the contiguous United States and Hawaii because they are rarely used. These frequencies are: 4125 kHz; 6215 kHz; 8291 kHz; and 12290 kHz. Advances in radio technology offer alternative means to send out distress notices. We will continue to monitor HF Digital Selective Calling distress alerting for all existing regions and voice distress alerting and hailing from Kodiak, Alaska, and Guam.
