EPIRB Class C is described as

• A. 121.5/243 MHz
• B. 121.5/243 MHz Manually activated version
• C. VHF Channel 70 Manually activated
• D. 406 MHz beacon

Answer: (C)

EPIRB Class C is defined by its use of VHF maritime DSC on Channel 70 with manual activation. This means the distress signal is sent directly over the VHF channel 70 when you press the manual button, alerting nearby vessels and coastal stations via the DSC system rather than relying on satellites. It’s different from 406 MHz beacons, which transmit via the COSPAS-SARSAT satellite network, and from 121.5/243 MHz beacons, which are older, primarily for local homing and not satellite-based DSC. So Channel 70 DSC manual activation best fits the description of this class.
