Sean Kelly Tour

Monday, September 13th, 2010

Since 2007, the Sean Kelly Tour has taken place on the last weekend of August. This year AREN was asked to assist Waterford County Civil Defence with locating the head and tail of both the 90k and 160k events to allow for efficient and effective ambulance deployment.

EI2GN, EI3ENB, EI7IG, EI5GOB and EI8JA turned up on the morning, and quickly set about the task. As the mobile command post was being set up, APRS was deployed into the sweeper vehicle for the 90k event, however the 160k sweeper had already left so a plan was formed to intercept the 160k sweeper later in the day, and EI3ENB, was dispatched to a food station to carry items to a Civil Defence ambulance already deployed to that station.

Below are a series of screen shots (from Xastir) depicting the progress of the event during the day.

All-in-all the day was very successful. Civil Defence were very appreciative of the information being supplied to them by us. Amateur Packet Reporting System (APRS), was used both for status updates/short messages, and, obviously for position reporting during the day. This meant that our own voice channels were kept free for more important traffic, and, in fact, very little voice traffic was passed during the day.

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 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.
