Hurricane Season

Wednesday, June 30th, 2010

The Atlantic Hurricane Season officially runs from 1st June to 30
November each year and  Tropical Storm Alex has become the first ‘named’
storm of this year. Amateur Radio continues to play a part in gathering
and distributing information for the weather and emergency services each

Radio Amateurs in Region 1 are reminded 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. It is possible for
Region 1 amateurs to cause unintentional QRM to these nets so please
listen carefully if operating near these frequencies.

14.300 MHz is used by the Maritime Mobile Service Net daily and as well
as handling traffic from Maritime Mobile Stations, also gathers weather
reports from maritime stations to assist forecasters.

14.325 MHz is used by the Hurricane Watch Net and the net is established
whenever it appears that a storm may affect the US mainland. The net
gathers weather information and links to the American National Hurricane

14.265 MHz is used by the Salvation Army Team Emergency Radio  Network (
SATERN )  provides Health and Welfare traffic links for those in
affected areas as well as supporting the Salvation Army Disaster relief
response should a hurricane strike.

Frequencies used in Cuba
7.045, 7.080, 7.110 MHz
3.740 MHz

Frequencies used in Central America;
Red Centro Americana :  7.090 and 3.750MHz
Guatemala: 7.075 MHz
Nicaragua: 7.098 MHz

Mexico (FMRE)3.690 and 7.060 MHz

Cuba and Mexico co-operate with long distance relays on 40m when
propagation makes this possible.

Local emergency communications groups may also activate if a hurricane
approaches their area and those frequencies would be announced at the time.

Galtee Walking Festival

Monday, June 14th, 2010

Members of several Amateur Radio Clubs came together to provide public service communications over the weekend of the Galtee Walking Festival June 5th and 6th. Communications were mostly good with the different walks. On Saturday, the weather was fantastic, a small issue with a patch lead was quickly resolved and communications were good for the rest of the day.  On Sunday, one walk was “new” and caused some difficulty at the beginning due to difficult communications, but this was quickly resolved. HF (80meters) was used as a backup in order to ensure communications across the Galtee Mountains. This worked very well and EI2KA checked in from Baltimore to check progress at regular intervals.

APRS worked very well.  This year EI3ENB brought along a Micro-Trak AIO which was given to one of the walk leaders to carry.  It worked quite well and gave excellent, trouble free service over the duration of the weekend. EI8JA and EI2JP both had Yaesu VX-8Rs with them which also worked very well. Extensive use was made of the mobile Kenwood TM-D710s in vehicles to act as digipeaters for the lower powered units.

The third is also from Sunday, but this time using the latest OpenStreetMap additions to Xastir


The performance of the Micro-Trak AIO was quite surprising, but allowed us to keep an eye on the A-Walks progress on both the Saturday and Sunday. Amateur Radio operators involved included EI5GOB, EI7IG, EI8JA, EI2JP, EI3FFB and EI2GN, totalling approximately 124 volunteer hours over the weekend.
