The National Short Wave Listeners Club (NSWLC) would like to announce a new HAREC online training course. Class Foxtrot will start on 3rd of November 2022. Class Foxtrot will consist of 24 classes ending on the 4th of May 2023. The course is free but membership of the NSWLC is compulsory. There are no prerequisites for this course, other than a genuine desire to study for an amateur radio licence, and to take and pass the Irish HAREC exam. The upcoming course is based on the new Irish exam syllabus, introduced earlier this year. The course uses the upcoming IRTS Study Guide, an almost 300-page learning resource. Members of Class Echo have significantly contributed to the new guide. As a result of their valuable feedback, Class Foxtrot contains six more sessions than its predecessor in order to better focus on the areas that are new to the current syllabus. The course will be held via the Zoom platform and sessions must be attended live. Classes will be held each Thursday from 8:00 p.m. to 10:00 p.m. local time.

This weekend Scout leaders Marty EI2IAB and John EI3ISB have a Radio station on the air from Portlick Scout Camp in County Westmeath. The grid locator is IO63BI, and the Worked All Ireland Square is WAI N02. They are promoting our hobby to other Scouters and Guiders from around the country. Marty (EI2IAB) says that they are on 80 to 10 meters, on VHF and UHF, and also on the local repeaters with the call-sign EI0YOTA. Also on the air this weekend are the Copper Coast Scouts and the Tramore 36, helped by The Collective Communication. They are experimenting with their self build kits, participate in a radio Fox hunt, followed by a treasure hunt, where teams of six use maps and radios to solve clues leading them to the treasure.

The South Eastern Amateur Radio Group EI2WRC is active from The Waterford and Suir Valley Railway station Kilmeaden, Co.

The Shannon Basin Radio Club announce that their weekly SSB nets will recommence at the end of September. The hugely popular nets draw in stations from all across Ireland, the UK, and further afield. The 80m net will restart on Thursday, the 29th of September, starting at 9 p.m. local time in the upper end of the 80m band. The exact frequency will be posted on Shannon Basin Radio Club's Facebook page and Twitter account before the net starts. All are very welcome to join, especially newly licensed amateurs, QRP stations, and portable operators. Information about the restart of the 160m topband weekly net will be advised at a later date. Anyone wishing to learn more, submit SWL reports, or interested about the wide range of club activities are welcome to contact Shannon Basin Radio Club by email at admin /at/ or via the club's social media channels.

On Tuesday, the 4th of October at 19:30, the South Dublin Radio Club will host a talk by Tony EI5EM relating to QRP construction and operation. Tony’s talk was very well received at this year's GI-QRP convention, so this is a great opportunity for attendees to ask questions and get information from someone who is very experienced in this area. The talk will be held in the downstairs conference room of Ballyroan Community Centre. There is limited capacity at the venue. Any non-club members wishing to attend are asked to contact southdublinradioclub /at/ . Alternatively, the talk will be live streamed via Zoom. Should you wish joins us via Zoom, please email us for login details.


UKEICC have just published the awards and plaques for the 2022 DX CW Contest which took place over the weekend of 30th of April and the 1st of May 2022. Congratulations to David EI5KG for winning the Paddy Smith Memorial Cup, sponsored by the IRTS There were 538 valid entries amidst poor propagation that weekend. Dave will be active as EI5G, the bonus station in the upcoming one hour duration UKEICC 80m CW Contest on Wednesday, starting at 20:00 zulu. See for details about this very popular contest.

VHF/UHF specialist Roger (EI8KN) was the only entrant from EI in the IARU-R1 50 and 70 MHz contest in April. He logged 131 valid contacts in 6 hours, earning him 3rd place, with his furthest 50 MHz contact over 3682 km to Cyprus. A very good result considering the absence of sporadic-E propagation during the contest, normally helping stations at the fringes of Region-1. Many other stations logged EI8KN as their furthest contact. Roger went on to better that result during his six hour stint on 70Mhz, coming first in his class.

The SSB leg of the 77th Oceania DX Contest will start at 06:00 UTC next Saturday, and will run for 24 hours. The exchange is signal report and serial number. The multipliers are weighted in favour of topband and 80m contacts, a good opportunity for DXCC chasers to fill in the gaps for the lower bands. The CW leg takes place the following Saturday and Sunday. Details can be found on

Next Sunday, 2 October, the RSGB DX Contest takes place between 06:00 and 9:00 UTC. Using CW and SSB on the 3.5 and 28 MHz bands where contests are permitted, the exchange is signal report and serial number. The RSGB DX contest is concurrent with other contests whose rules specify alternative exchanges. When making contest QSOs with participants in other events, please log a 'sent' serial number for each QSO, whether or not you have actually sent it. Details about this, and other RSGB contests can be found on

The Propagation Horoscope

Within the harsh conditions of sun's outer atmosphere, the corona,  atoms are stripped of their electrons, forming the fourth state of matter called plasma. Supercomputers at NASA have been used to model the exact movement of electrons and ions in the solar plasma, examining the generation of high-energy particles when magnetic fields in the corona accelerate electrons and ions close to the speed of light and then launching them into space. When filaments of magnetic fields become unstable and get pinched off, they can take some plasma with them and help launch an excess of high energy particles into space, as happened on Friday noon at around 13:30 UTC. A wide filament of magnetism near the sun's southwestern limb became unstable and erupted, resulting in a Coronal Mass Ejection (CME) and a strong radio burst. Not direct towards Earth, it will nevertheless combine with effects of gaseous material flowing out from an equatorial hole in the sun's atmosphere, likely leading to G-class geomagnetic storms over the weekend, creating some interesting propagation conditions on HF. Geos 16 reports a background x-ray flux at the class C1 level. As of writing, the Flux values are at a healthy 130 km per second. Barring further surprises the good conditions on the higher bands over the past few days will improve further. The night-time MUF will briefly drop below the 20m band, the day-time MUF will not quite reach the 10m band yet, meaning that early birds will be rewarded with 20 and 15m DX towards Asia and Oceania. The lower bands have come alive again, especially 40m with both short and long path openings.

That is the news for this week. Items for inclusion in next week's radio news can be submitted by email to newsteam /at/ for automatic forwarding to both the radio and printed news services. The deadline is Friday noon.
