USCG Exam PracticeGMDSS and VHF distress procedures
When making a voice MAYDAY call on VHF, the distress frequency you should select is:
- ✓ 156.8 MHz (channel 16)Correct
- B. 157.1 MHz (channel 28)
- C. 156.3 MHz (channel 06)
- D. 162.55 MHz (NOAA weather)
Why A is correct
46 CFR §184.510(a)(2) and 46 CFR §28.265(d)(4)(ii) both specify 156.8 MHz (VHF channel 16) as the primary voice distress and calling frequency. Channel 16 and 2182 kHz on SSB are for emergency and calling purposes only.
