Monitoring the Hurricane Hunters and More During the Hurricane Season

The July issue of The Spectrum Monitor is going to be released today and my monthly Milcom column will have detailed coverage of frequencies and call signs used by the US Government/Military agencies to study, track and report on hurricanes and tropical systems. It includes the latest information on the US Air Force and NOAA Hurricane Hunters.

It has been almost a decade (2008 in Monitoring Times magazine) since my last article on this subject so I had a lot of updates and information to share.

Yesterday, Curt Phillips shared with the Tarheel Scanner Group a list of Amateur Radio frequencies you can monitor during the hurricane season. With possible tropical activity developing off the southeast US coast or Gulf of Mexico in the next few days, my TSM list and this ham radio frequency list from Southgate should be helpful to stay informed.

On the IARU Region 1 site Greg Mossop G0DUB reports on the amateur radio nets that may be active during the Atlantic Hurricane Season June 1 to November 30

So it is time to remind the wider Amateur Radio community that the following frequencies may be in use by nets in North and Central America to track and deal with the consequences of these severe weather events. Radio Amateurs in Region 2 play their part in gathering and distributing information for the weather and emergency services as they do every year.

Radio Amateurs in Region 1 are reminded it is possible to cause unintentional QRM to these nets so please listen carefully if operating near these frequencies:

Belize: 7.177MHz
Caribbean Emergency & Weather Nets (CEWN): 3.815 & 7.162 MHz
Caribbean Emergency: 14.185 MHz
Central America: 7.090 & 3.750 MHz
Cuba: 3.720, 3.740, 7.110 and 7.120 MHz
Eastern Caribbean Narrow Band Emergency System Net: 7.036 MHz USB (Olivia & MT63)

Mexico: 3.690, 3.693(Alternative), 7.060 & 14.120 MHz
Nicaragua: Main Frequencies 3.798, 7.098, 14.298 MHz Alternate Frequencies 3.898, 7.108, 14.198MHz

Other local emergency communications groups may also activate if a hurricane approaches their area and those frequencies would be announced at the time.  Thanks to the National Societies and Emergency Communications Groups of IARU Region 2 for updating their frequency information.
