Comeragh Challenge

Sunday, July 4th, 2010

This year marks the 14th anniversary of the Comeragh Crossing, from Clonmel to Dungarvan. The walk has developed over the years into a national event, and has raised more than €110,000 for charity. The committee led by John Neylin have organised a great day on the mountains, catering for walkers of all levels and fitness. Last year over 160 walkers took part.

Behind the scenes there are over 60 enthusiastic members who volunteer yearly. They man the checkpoints; lead the walkers over the route; brew the tea on the mountaintops; and make dinner back at the check-in; and still remember to turn on the hot water for the showers!

There are actually 4 different options available to walkers on the day.  The Comeragh Challenge which is approximately 40km. long with about 2000m of ascent. The average walking time is approx 10 hours, though 2 hardy men finished it in less than 6 hours yesterday. The Comerach Crossing is approx 30km. long with 1150m of ascent. There are three stages to the walk and it is possible to join at either Stage 2 or Stage 3, later in the day.

Invariably this means that communications (assuming nothing happens) is mostly about “missing” walkers, walker leaving the walk and needing transport, and making sure that no walker goes missing between manned checkpoints.

One checkpoint in the Nire Valley poses a particular challenge, and, as a back up, communications were establised with  80m NVIS mode propagation to ensure communications between this location and base in Dungarvan.

Members participating included EI8JA, EI5GOB, EI2IT, EI3ENB, EI2KA and EI7IG, with operation being wrapped up at approximately 19:00, with all walkers accounted for and en-route back to base.

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.
