Important Notice: Emergency Frequencies — Keep Clear During Contest Weekend
As the Caribbean faces potential hurricane impacts, IARU Region 2 has activated emergency nets on the following frequencies:

40 meters: 7.198 MHz and 7.098 MHz

20 meters: 14.198 MHz

If the Hurricane Watch Net (HWN) activates, they will be operating on:

14.325 MHz

7.268 MHz

The amateur radio station at the National Hurricane Center, WX4NHC, will also be monitoring the HWN frequencies for real-time weather and situation reports.

This weekend coincides with the CQ World Wide SSB Contest, one of the busiest times on the bands. All operators are urged to exercise extra vigilance and avoid transmitting on or near these emergency and hurricane watch frequencies.

These nets are providing critical communication links supporting the Caribbean Islands and affected regions. Please ensure they have clear and reliable access to designated frequencies.

In summary:

Keep clear of 7.198, 7.098, 7.268, 14.198, and 14.325 MHz

Be aware of possible emergency or health-and-welfare traffic on nearby frequencies

Operate responsibly and help maintain open frequencies for those supporting hurricane response efforts.
