IRTS Contest News

Results of the IRTS 40 metres Counties Contest held on 9th May have now been published, see for full details. Band conditions on 40 metres were very poor on the day, with almost no short skip. County multipliers were therefore in short supply for EI and GI stations. However, there was good support from overseas stations, which accounted for almost 80% of the QSOs logged.

Linking La Crosse, Wisconsin and Ireland via Amateur Radio

La Crosse is a city on the Mississippi River, in western Wisconsin in the USA and this year in mid-august they will be holding their 16th annual Irishfest. What’s different this year is that amateur radio is being introduced into the programme and the Riverland Amateur Radio Club is issuing an invitation to Irish amateur radio clubs and individuals to get involved in linking La Crosse with Ireland during the festival. The plan is that operations will be held on Saturday August 14th between 1600 and 2200utc on 14.260MHz. They will also operate on the Riverland Club’s repeater on Yaesu Wires-X room 63956. Shawn KD9KGQ would love to hear from any Irish amateurs interested in participating in the event.

CW Field Day

IRTS CW Field Day takes place next weekend the 5th and 6th of June. This contest is for portable stations and is on the CW contest preferred segments of the contest bands from Top Band to 10 metres. It runs for 24 hours from 1500 UTC on Saturday 5th June and there is a 24 hour section and a restricted 6 hour section. The first weekend in June is when a number of IARU Region 1 societies would normally run CW Field Day contests and has always been a good opportunity for European CW operators test their skills in a portable environment. The covid pandemic has affected field day and other contests over the past year and no IRTS field day events were held in 2020. Following improvements in the public health situation in recent months, we decided to proceed with our field day events this year, subject to restrictions and precautions that have been inserted into the contest rules. We note that DARC, the German national society, has decided to cancel its CW Field Day this year; while it acknowledges the improved health situation, it is concerned that regulations or restrictions may not be uniform throughout the country. The RSGB CW Field Day contest is going ahead, so we can expect plenty of activity from UK portable stations.

Amateur Radio on the International Space Station
