The news headlines:
- The RSGB releases a video to celebrate Volunteers’ Week
- Get involved with the GR2HQ contest challenge
- Join the RSGB Regional Team
As Volunteers’ Week comes to a close, the RSGB would like to thank its volunteers once again for all they do. As part of the week-long event, the Society released a video about the volunteer team at the RSGB National Radio Centre. These volunteers welcome over 80,000 visitors to the Centre every year and share amateur radio with them. Watch the video to discover the variety of things that they do as well as what they enjoy most about their role. You’ll find the video at rsgb.org/volunteers-week, and on that web page, you’ll also be able to read about several volunteers in other RSGB roles. If their stories have inspired you and you would like to give some time to support the RSGB and amateur radio, look at the vacancies on the RSGB website at rsgb.org/volunteers
The RSGB Contest Committee is looking forward to the IARU HF Championship contest on the 12th and 13th of July. This is a great opportunity for both individuals and clubs to get involved. During the contest, Headquarters Stations represent their countries, and the RSGB’s station GR2HQ will be run by a network of about a dozen stations around the UK and its islands. Building on the success of last year's GR2HQ Challenge, the RSGB Contest Committee has made some changes to encourage individual stations to work the GR2HQ station on each band-mode slot. Sharing your QSOs for scoring has also been made easier. The contest is open to both individuals and clubs, so why not encourage your club members to take part, whether they are regular contesters or not? Last year, thanks in part to those entering the GR2HQ Challenge, the RSGB Contest Committee improved its position from third to second and would like to improve that result even further. Could you take part and make a difference? For the full rules, go to the GR2HQ Challenge page on the Contest Committee website via rsgbcc.org
The RSGB has several volunteer vacancies within the Regional Team. If you are passionate about the future of amateur radio and support the work of the Society, then apply now. These rewarding roles are an opportunity to support fellow radio amateurs in your area. Vacancies include District Representative positions in Staffordshire, Oxfordshire and Dorset. To view the full list of regional team volunteering vacancies, go to rsgb.org/volunteers. If you have questions about the District Representative roles, contact the Regional Representative in that region, or you can contact Board Liaison Nathan Nuttall, 2M0OCC, for a chat via 2m0occ@rsgb.org.uk
A special interactive spy event is taking place on Father’s Day, Sunday the 15th of June, at the RSGB National Radio Centre. You’ll have the opportunity to become a spy hunter and, using your special gadget, will be tasked with finding hidden transmitters located around Bletchley Park. You’ll need to decode Morse signals and uncover the location of the secret spy base. Two time slots are available, however, spaces are limited to 12 groups for each. Secure your place and treat your Dad, Grandad, or a father figure to a fascinating day out by going to bletchleypark.org.uk and selecting the ‘What’s on’ option in the main menu. The activity is free to take part in, however, entry to Bletchley Park is required. Don’t forget that RSGB members get free access to the historic site as a membership benefit. Download your voucher via rsgb.org/bpvoucher

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 5th of June
Last week’s HF propagation was heavily influenced by unsettled geomagnetic conditions. This was caused by a combination of coronal mass ejections and a strong solar wind from a coronal hole.
The coronal mass ejection, or CME for short, followed a solar flare from sunspot 4100 on the 31st of May at 0005 UTC. The explosion lasted more than three hours. Type 2 radio emissions from shock waves within the CME cloud suggested it was travelling at 1,938 kilometres per second, or 4.3 million miles per hour!
Eventually, the Bz swung south. This meant that the interplanetary magnetic field more easily coupled with the Earth’s magnetic field. The result was that the Kp index got up to 7.67 on the 1st of June.
The auroral effects were reported as being due to a co-rotating interaction region, or CIR – a region in space where fast and slow solar wind streams collide, creating a compressed area with enhanced plasma and magnetic fields.
The Kp index was 7 or more for four three-hour periods. This pushed the maximum usable frequency over a 3,000km path below 14 MHz at times, which wasn’t conducive to good DXing.
On Thursday, the 5th of June, it looked like we were past the worst, and the Kp index was back to a more reasonable 2.33.
Meanwhile, the solar flux index declined from a recent high of 164 on the 31st of May to a low of 134 on the 5th of June. HF propagation was being driven by the geomagnetic conditions, with a general lowering of the maximum usable frequency.
Next week, NOAA predicts that the solar flux index will start the week at around 155 and remain around 150. More worryingly, geomagnetic conditions are again predicted to be unsettled after this weekend, with a maximum Kp index of 6 on the 13th of June.
So, unsettled geomagnetic conditions, plus the HF summer doldrums, mean HF DX via F2-layer propagation may be hard to find. So, make the most of the 10m Sporadic-E short-skip openings instead!
And now the VHF and up propagation news from G3YLA and G4BAO
Last week offered an example of what a good Sporadic-E season should look like. On Tuesday, the 3rd of June in particular, the 6m band sounded like the 20m band and, at its peak, activity extended all the way up to the 2m band.
This coming week has an unsettled flavour with several areas of low pressure and weather fronts involved, together with heavy showers in between. This means rain scatter will be a supported mode on the GHz bands.
There is a slight hint of a slow improvement during the week, but not really any high pressure showing up until right at the end of the coming week. So, there is a chance of Tropo propagation for the 2nd 144MHz Backpackers Contest on Sunday, the 15th.
Meteor scatter is always interesting in June, with four showers to play with during the month. The early ones are the Arietids, which peaked on Saturday, the 7th of June – good news for the 50MHz UK Activity Contest on Thursday the 12th.
The Zeta Perseids peak tomorrow, the 9th of June, and there will be a couple of other showers later in the month. This is probably also why the Sporadic-E prospects improve about now.
Aurora has also been much in evidence recently. Despite the light summer evenings and short nights, the chances of radio aurora continue to be important, so monitor for high Kp values above about 5.
The advice for some who have not yet worked Sporadic-E is to check the 6m band around teatime.
There are, of course, usually two primary periods when Sporadic-E is more likely: one in the morning, and the second in late afternoon and evening. A morning opening may repeat in the afternoon in similar locations, although usually the weather trigger may have moved a little in the meantime.
Check the jet stream charts at propquest.co.uk by following the Sporadic-E blog tab. The daily commentary will highlight the important directions each day. You can hopefully test out the system on Thursday, the 12th of June, in the 50MHz UK Activity Contest.
EME path losses were at their maximum with apogee, when the Moon is at its furthest from the Earth, on Saturday, the 7th of June. Declination reaches a minimum on Wednesday, the 11th, so Moon windows are short and peak elevation is low. 144MHz sky noise peaks around the 11th and 12th of June. EME conditions were classed as poor this weekend and are classed as poor-to-moderate on the 14th and 15th of June.
And that’s all from the propagation team this week.
