Which frequency pair is associated with EPIRB Class S Float-Fix?

• A. 121.5/243 MHz
• B. 406/121.5 MHz
• C. 121.5/250 MHz
• D. 406/243 MHz

Answer: (A)

The key idea is that EPIRB Class S Float-Fix provides a dedicated homing signal on the classic distress frequencies to help rescuers locate the beacon after the alert is received. While the 406 MHz signal handles the satellite alert to the Cospas-Sarsat system, rescuers rely on the continuous homing signals at 121.5 MHz and 243 MHz to direction-find and pinpoint the beacon on scene. So the frequency pair associated with Float-Fix is 121.5 and 243 MHz. The other options don’t match the standard homing combination used by this class of beacon.
