The news headlines:

• The RSGB Convention is just three weeks away

The RSGB Convention is just three weeks away and there is a fantastic programme planned. Whatever your amateur radio interests or experience there will be something for you. In addition to the presentations, you could take part in a workshop to learn more about microcontroller programming – spaces are limited so make sure you book soon if you want to be part of that event. There will also be an EMF and EMC Clinic, contest forums and a chance to find out more about a wide range of amateur radio special interest groups. The social side of the Convention is important too, whether you’re catching up with friends over coffee or enjoying the Gala Dinner on Saturday evening. Day or weekend tickets for the Convention are still cheaper if you buy in advance rather than on the door, and the deadline for advance tickets is Monday the 7th of October. To find out more about the programme, the speakers and to book your tickets, go to the RSGB Convention web pages at rsgb.org/convention

The RSGB has announced that from the 29th of November it will stop taking routine bookings for paper exams. Currently 97% of amateur radio licence examinations are taken online using the TestReach platform, either at home under remote supervision or in a club setting. Following the implementation of Syllabus v1.6 on the 1st of September 2024, the new examination question bank will only be maintained online. Generating paper exams will involve significant additional work for the RSGB Examinations Department, with the associated costs. You will be able to apply for a paper exam on the grounds of special educational needs in the same way that you can currently request special requirements such as extra time or a reader. To do that you need to email the Exams Department via [email protected]  To read the full details of the changes, including the three important dates you need to know, please go to the RSGB website at rsgb.org  and search for ‘Exam Announcements’.

Do you work with young people at a school, or perhaps with a youth group such as the Scouts, Guides or Cadets? Are you looking for an activity that provides hands-on learning opportunities for them? The RSGB National Radio Centre currently has availability for two private evening visits in December as part of the Society’s activities for Youngsters on the Air month, or YOTA month as it is often called. Sessions typically last two hours and include an introduction to amateur radio, before the youngsters are split into smaller groups to complete a variety of activities. These can include Morse code, VHF communication using handhelds, shortwave radio communication and satellite communication. The group size is limited to a maximum of 12, and there must be one adult accompanying every four students. If you’d like to find out more about this unique learning opportunity, email the RSGB National Radio Centre Coordinator Martyn Baker, G0GMB via [email protected]

The next Bletchley Park 1940s weekend is taking place at the moment. If you are visiting for the event, make sure you drop into the RSGB National Radio Centre where you’ll be able to see a number of World War Two receivers on display. Don’t forget that RSGB members can get free entry to Bletchley Park, which also includes admission to the RSGB National Radio Centre. You can access this fantastic offer by logging into the RSGB membership portal via rsgb.org/members  and selecting ‘Visit Bletchley Park’.

Don’t forget that National Hamfest 2024 is coming up on the 27th and 28th of September and promises to be an unforgettable celebration of all things amateur radio. As always, the traders and manufacturers are lining up to bring you the best in amateur radio equipment and accessories. Many exhibitors will be offering exclusive deals, making it the perfect time to upgrade your gear or add new items to your shack. For more information and to purchase your tickets, visit nationalhamfest.org.uk 

Railways on the Air weekend usually takes place on the weekend closest to the 27th of September. This date celebrates the anniversary of the first steam-powered passenger railway journey which took place on the 27th of September 1825. The first passenger train ran on a line in the North East of England from Darlington to Stockton. Bishop Auckland Amateur Radio Club coordinates the event and this year it will take place over the weekend of the 28th and 29th of September. For more information visit rota.barac.org.uk

The next event in the popular 145 Alive series takes place on Sunday the 29th of September. The event will run from 1 pm to 4 pm and there will be nets operating in most Maidenhead Squares across England, Scotland, Wales and Ireland. To take part in the event, which is designed to promote FM activity on the 2m band, all you need to do is call in and make contact with others. The organisers are looking for more net controllers. For more information contact Mark Savage, M0XIC via the 145 Alive Facebook page.

On Monday the 7th of October the RSGB’s Tonight@8 live webinar will be with Ian White, GM3SEK who will give a presentation entitled ‘Aircraft Scatter, the Hitch-Hikers Guide’. Aircraft scatter is about bouncing VHF and UHF radio signals off high-flying aircraft – effectively ‘hitching a ride’ with someone else’s plane to extend your everyday working range up to 800km. For example, if you are one of the hundreds who get involved in the monthly UK Activity Contests on the 2m, 70cm and 23cm bands, you will already be using aircraft scatter routinely and it will be responsible for some of your best QSOs. So how does aircraft scatter work? And if it’s so useful, why haven’t we heard more about it? Join the webinar live at 8pm on the RSGB YouTube channel or special BATC channel. Find out more about this and other webinars on the RSGB website via rsgb.org/webinars

 Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 19th of September 2024

It was a topsy-turvy time for HF propagation last week with a declining solar flux index and geomagnetic disturbances thanks to coronal mass ejections, or CMEs, from the Sun.

The solar flux index declined to the mid-160s, and the Kp index had a couple of excursions to more than 7. These were due to CMEs and the second, which occurred on Tuesday the 17th, was associated with the X4.5 solar flare on Saturday the 14th.

Luckily, it was 0300UTC when the CME hit the Earth, so only die-hard UK DXers were affected. With a G4 geomagnetic storm raging, the maximum useable frequency over a 3,000km path fell to less than 6MHz, but did manage to recover to 8.45MHz by dawn.

The rest of Tuesday was subdued with the maximum useable frequency never really getting above 21MHz. This is why the advice is often to avoid DXing when the Kp index climbs high, as the upper HF bands will likely be closed.

By comparison, on Thursday the 19th the Kp index was 2.67 and the maximum useable frequency over 3,000km was above 28MHz again.

NOAA puts the risk of another X-class flare at 10%, and an M-class event at 55%. So, we are not out of the woods yet.

Next week, the Space Weather Prediction Centre says the solar flux index may decline slightly but could then rise to be in the 232 to 240 range. Geomagnetic storming is predicted for the 26th to the 29th, when the Kp index could rise to 5.

Meanwhile, autumnal HF conditions should soon be kicking in with better propagation to North America. If the solar flux stays high, we can expect excellent 28MHz propagation, perhaps to the mid-west and Pacific states.

North-South HF paths, such as the UK to South Africa and South America, should also be good around the equinox period.

And now the VHF and up propagation news from G3YLA and G4BAO

The last week of Tropo gave us good conditions across the North Sea and up and down the country on the VHF and UHF bands. 

It is very likely that there will be a big change of weather type over this weekend, ending today the 22nd, to a much more unsettled pattern with low pressure dominating during the coming week.

In fact, there will be a sequence of lows, fronts and showery interludes to set the template for next week. This means that rain scatter is a good candidate for propagation on the GHz bands, which could be useful on the evening of Tuesday the 24th during the SHF UK Activity Contest. Meanwhile, tropo takes a back seat for a while.

The solar activity continues to be of interest and, again, the message is to monitor the Kp index to keep one step ahead of events in case any aurora spring up.

Meteor scatter is mainly down to random activity, although the daytime Sextantids peaks on Friday the 27th of September, but with a low zenith hourly rate of 5.

For EME operators, Moon declination is positive and rising, reaching +29 degrees next Tuesday, so Moon visibility windows will continue to lengthen. Path losses are increasing as we passed perigee last week. 144MHz sky noise is moderate, dropping back to low next Thursday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 12th of September 2024

Last week showed that HF conditions are improving as we head into the autumn.

With a solar flux index still above 200, there was plenty of DX available to work. CDXC members reported working VP6WR on the Pitcairn Islands, KH8T on American Samoa and 3D2USU on Fiji, which is not a bad catch for early September.

A little closer to home, 9A168TESLA in Croatia has been popping up for short periods celebrating the 168th anniversary of the birthday of electrical pioneer Nikola Tesla. Watch DX Summit closely for operating times.

The daylight maximum useable frequency, or MUF, over 3,000 kilometres remains above 28MHz on the whole, although a raised Kp index tends to reduce this.

Geomagnetic conditions remained relatively calm with the Kp index below 3 all week. That changed on Thursday the 12th as material from a coronal mass ejection, or CME passed the ACE spacecraft in the early hours.

The solar wind speed increased to more than 500 kilometres per second and the Bz swung south. On Thursday the 12th, the Kp index was 5 and the Met Office Space Weather department was forecasting potentially unsettled conditions for this weekend, ending today the 15th.

At the same time an X-class flare occurred, with lowered MUFs due to increased D-layer absorption.

Two large coronal holes on the Sun’s surface are also now Earth-facing and threaten to add to the solar wind this weekend.

According to NOAA’s predictions, the solar flux index should stay in the 210 to 225 range next week, although a large number of spots are about to rotate off the Sun’s visible disk.

This may be compensated by an active region that’s about to rotate into view. This has been emitting C-Class and lower-level M-flares and could potentially be the same region that produced several energetic eruptions off the far side of the Sun over the past week. Time will tell.

And now the VHF and up propagation news from G3YLA and G4BAO

The heavy showers at the end of last week produced some good rain scatter, but no QSOs in the UK were noted due to the showers not coinciding with GHz contests and few suitable home stations were active to take advantage of them.

After a gradual build-up of pressure over this weekend, ending the 15th, high pressure is suggested by most models during the coming week. However, there is some uncertainty about the position of the high.  

Currently, models are favouring the north of Britain and this means that in the south, although still on the edge of high pressure, there could be a brisk northeasterly breeze, which may weaken the inversion prospects. It’s not clear if the Tropo will be functioning in time for the 70MHz Affiliated Societies Contest today, the 15th, but should be helpful for the 1.3GHz UK Activity Contest on Tuesday the 17th and the 70MHz UK Activity Contest on Thursday the 19th.

Solar conditions are still likely to offer the chance of the occasional elevated Kp index, which is a good sign of possible aurora. It will be interesting to see how things evolve this weekend, ending the 15th, as a series of expected CMEs are due to reach Earth. 

The amateur bands between 10m and 2m are the ones to check as well as looking out for ‘watery’ sounding signals on the HF bands. Remember it doesn’t have to be dark for radio aurora, so don’t wait for dusk before checking.

Meteor scatter is mainly down to random activity in the coming week. However, with the September Epsilon Perseids stream still active until the 21st, having peaked on the 9th, conditions may be slightly enhanced.

For EME operators, Moon declination is negative but rising and going positive again on Wednesday the 18th. Moon visibility windows will continue to rise while path losses decrease as we approach perigee on Wednesday the 18th. 144MHz sky noise is moderate for the whole of next week.

And that’s all from the propagation team this week.

• Book your RSGB Convention tickets now

The RSGB Convention is just five weeks away and an exciting programme of presentations and practical activities is being prepared. The early bird price for day tickets ends on the 15th of September and this year there won’t be any extensions to that date! As well as three streams of presentations across the weekend there will be an introductory workshop on microcontroller programming. This workshop is part of the Society’s aim to widen the programming skills in the amateur radio community and to introduce people to something new. On Saturday morning RSGB experts will give an EMC and EMF update presentation, followed by an informal EMC and EMF clinic in the afternoon. The RSGB HF and VHF contest forums will take place on Sunday. Throughout the weekend there will be opportunities to talk to RSGB representatives and to members of many special interest groups who could inspire you to try a different aspect of amateur radio. The RSGB 2024 Convention – your convention, your way. To book your day tickets and to book for the workshop, go to rsgb.org/convention

The RSGB has 13 regions, each covered by a Regional Representative and a team of District Representatives. This volunteer team is an important link to clubs and a potential source of support and information for individual radio amateurs. There are several vacancies in the Regional Team and this month we’re highlighting two regions. In Region 5 there is an opportunity for someone to volunteer as a District Representative covering Gloucestershire, Hereford and South Worcestershire. There are also two vacancies in Region 13 for District Representatives to cover Leicestershire and Rutland, and also North Lincolnshire. If you’re interested in supporting local radio amateurs and clubs in those areas, please contact the appropriate Regional Representative. You can find their details by going to our website at rsgb.org/regions and clicking on the region in which you live.

Next Saturday, the 14th, lots of amateur radio stations will be on the air to take part in the Churches and Chapels on the Air event, also known as CHOTA. The event will take place from 10 am to 4 pm and operation will be focused on the 80, 40 and 20m bands. To see the list of churches and chapels taking part visit the ‘CHOTA’ tab on the World Association of Christian Radio Amateurs and Listeners website at wacral.org

Several changes have been made to the RSGB contest trophies process, for logistical and resource reasons. For example, instead of engraving each trophy, the winner will be presented with a quality certificate at the Trophy Presentations on Sunday morning at the RSGB Convention. For each award, a high-quality photograph will be taken of the winner with their trophy, and that photo will be available for the winner if they would like it. RSGB HQ will now administer all trophies for the AGM event. The full changes are shown in the updated trophy policy on the RSGB website at rsgb.org/trophies  If you have any questions about these changes, please contact the RSGB Trophy Manager Mike Franklin, G3VYI via [email protected]

Over the course of a year, radio amateur Maggie laquinto, VK3CFI attempted to make contact with Russian cosmonauts on the Mir space station. Maggie used her amateur radio skills and equipment to monitor the orbit of the space station and listen to the frequencies that it used. After the dissolution of the Soviet Union in 1991, Maggie relayed crucial information to cosmonaut Sergei Krikalev. In a recent BBC programme, Maggie’s son Ben laquinto speaks to Megan Jones. You can listen to the programme by searching for ‘The woman who spoke to the space station’ on the bbc.co.uk website.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 5th of September 2024

Last week was underlined by continued high solar flux indices and excellent 10m band propagation to CY9C on Saint Paul Island near Newfoundland.

The DXpedition, which has now ended, was often at S9+ on 28MHz up to two hours after sunset. This may be a sign that better autumnal HF conditions are just around the corner and bodes well for the rest of the year.

The average sunspot number has now exceeded 200 for the first time in 23 years. This puts it significantly better than Solar Cycle 24 and it looks like there is more to come.

Propquest.co.uk reports that maximum usable frequencies over a 3,000km path are now often above 28MHz, so look out for DX on the 10m band. This will improve as the month goes on. September is a good month for north-south paths and paths to North America will improve as we head into October.

So, get your higher HF band antennas sorted out, as this autumn could be fun!

During the week just past, there were 21 M-class flares, but no X-class events. The Kp index has been under 5 all week, which no doubt helped HF propagation flourish.

Large coronal mass ejections, or CMEs, did occur on the 1st and 3rd of September, but these appear to be related to far-side events, well beyond the northwest limb and were directed away from Earth. But that active region is now rotating into view so buckle up for potential Earth-directed CME activity.

Next week, the Space Weather Prediction Centre suggests that the solar flux index will remain in the 240 to 250 range. Unsettled geomagnetic conditions are forecast for today, the 8th of September but, as we always say, keep an eye on solarham.com for up-to-date solar information as things are likely to change each day.

And now the VHF and up propagation news from G3YLA and G4BAO

The slightly enhanced Tropo conditions were welcome for the 144MHz UK Activity Contest on the 3rd of September. However, in the coming week, the opposite is now the case for many parts of the country as low pressure is set to dominate the weather charts.

There may be some weak ridges of high pressure nearby or even over northern Britain this weekend, but it is not looking great.

If pressed for a direction, it looks better across the North Sea to northern Europe and southern Scandinavia in the first part of the week.

Much of next week will have low pressure in control, and it will be worth looking for rain scatter on the GHz bands.

The solar side of things means that we should be alert to the chance of aurora if the Kp index rises. The autumn is often a good time of the year for these. It will be useful to monitor the Kp index, especially if you hear any signals sounding ‘watery’ on the HF and LF bands.

It’s always worth a reminder that the Sporadic-E season does not drop off a cliff at this time of year.  That said, it does become very infrequent and restricted to lower bands or digital modes under the influence of jet streams.  The southward paths to Iberia and the western Mediterranean look most promising next week for an out-of-season chance Sporadic-E event.

There is one small meteor shower this week. The September Epsilon-Perseids peaks with a low zenithal hourly rate of five tomorrow, the 9th. This shower produced unexpected outbursts in 2008 and 2013, but modelling indicates that 2024 activity should be nothing unusual.

For EME operators, Moon declination is now negative and falling further, reaching minus 29 degrees next Wednesday. Moon visibility windows continue to fall, as will peak Moon elevation, while path losses are decreasing after apogee. 144MHz sky noise increases from moderate today, the 8th, reaching over 2,500 Kelvin next Wednesday.

And that’s all from the propagation team this week.

The news headlines:

• RSGB collaborates on a special contact with the International Space Station

We are delighted to announce that the Radio Society of Great Britain and ARISS, in conjunction with Girlguiding Surrey West and Brooklands Museum including the Innovation Academy, have been collaborating on a special event due to take place on Saturday the 5th of October. Girlguiding President, Her Royal Highness The Duchess of Edinburgh will attend a planned contact with the International Space Station as part of a visit to promote the engagement and involvement of girls and young women in science, technology, engineering and maths. Further details of the contact and the event will be announced in late September.

The RSGB’s autumn Tonight@8 programme starts this Monday, the 2nd of September. Brian Coleman, G4NNS will give an update on the Meteor Beacon Project which is a cooperation between the worlds of amateur radio and astronomy. The first phase of this project was completed in May 2022 when the UK meteor beacon GB3MBA went on the air from the Sherwood Observatory of the Mansfield and Sutton Astronomical Society. It enabled studies of meteor events over the UK using simple equipment and made possible a range of STEM projects featuring radio and astronomy. The second phase of the project, which Brian will describe in the presentation, is to develop a network of receivers streaming their data via a central server for detailed studies of individual meteor events. You can watch and ask questions live on the RSGB YouTube channel or a special BATC channel. To find out more go to the RSGB website at rsgb.org/webinars

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 29th of August 2024

We had a good week for HF propagation, at least until we had a Kp index of 5.67 on Wednesday the 28th. This was caused by the Bz component of the interplanetary magnetic field moving into a south-pointing position.

Luckily, it didn’t last long and geomagnetic conditions were back to normal by Thursday.

The solar flux index remains above 200 with no sign of it dropping. But solar flare activity has not diminished either with 16 M-class flares over the past seven days and more than 60 C-class events. There remains a 55% chance of a further M-class flare and a 10% chance of an X-class event.

Tuesday the 27th saw some good activity on the upper HF bands with the 10m band opening up at times. VK has been heard on 28MHz in the mornings, which bodes well for the coming months.

The top DX choice this week has been CY9C on Saint Paul Island near Newfoundland. The team is active on all bands until the 5th of September using CW, SSB, FT8, Super Fox and RTTY. VOACAP Online shows that the 20 and 17m bands offer the best chance for a contact and are open from 0900 to 2000 UTC. The 30m band is another strong contender from 2000 to 1000 UTC.

Next week, NOAA predicts that the solar flux index will start at around 250 but could end the week at 275. As always, it estimates the Kp index will be at 2 all week, but this will depend upon coronal mass ejections, so keep an eye on solarham.com for daily updates.

If a solar flare and associated coronal mass ejections do occur, expect the Kp index to rise after about 48 hours, with a lowering of the maximum useable frequency.

And now the VHF and up propagation news from G3YLA and G4BAO

The autumn season usually brings thoughts of Tropo since areas of high pressure can often be a feature of this time of year. Most models predict that there will be high pressure moving in to offer Tropo conditions today, the 1st.

Thereafter, the models differ, and some bring low pressure over the country for much of the coming week, while others maintain a high-pressure story and the continuation of Tropo.

This is potentially useful for the 144MHz UK Activity Contest on Tuesday and Wednesday and, if it lasts, the 144MHz Trophy Contest next weekend along with the Backpackers contest on Sunday the 8th.

With the uncertain feel of the forecast at the moment, we may find rain scatter is the main option on the GHz bands.

Meteor scatter is again reduced to non-shower random events with just a minor shower, the Aurigids, peaking on the 31st of August. This shower has produced brief unexpected outbursts with a zenithal hourly rate of around 30 to 50 per hour in 1935, 1986, 1994 and 2019.

Random meteor flux is at its annual maximum in September with relatively good rates, especially during morning hours. Pre-dawn is the best time to try.

The solar conditions continue to provide chance auroras. Keep one eye on the Kp index and lock the frequency of some northern European beacons into your rig’s memory.

Lastly, it's the nominal end of the 2024 summer Sporadic-E season and the daily blogs on Propquest have finished. However, some years can produce surprise Sporadic-E events during the first week of September.

Moon declination starts the weekend still high but falling, going negative again on Thursday the 5th. So, Moon visibility windows will also fall, as will the peak Moon elevation.

Moon apogee is also next Thursday so path losses are still increasing. 144MHz sky noise is low until Monday but, shortly after moonrise that day, the Sun and the Moon become close in the sky and continue to be until after moonset on Tuesday.

This means sky noise will be very high, especially at VHF, due to wide antenna beamwidths. 

And that’s all from the propagation team this week.

GB2RS News

Sunday the 25th of August 2024

The news headlines:

• The RSGB 2024 Convention will feature a microcontroller programming workshop

At this year’s RSGB Convention, there will be a workshop to introduce attendees to microcontroller programming through a short presentation followed by practical exercises. The Society aims to widen the programming skills in the amateur radio community and introduce individuals to radio-related usage of Micro Controller Units, or MCUs. If you attend the workshop, you will receive a genuine Arduino board, a set of DuPont wires, a breadboard and two specific devices which you will be able to take away with you at the end of the workshop. The exercises will take you through using the Arduino IDE, basic programming and interfacing to the provided devices. You need to pre-register as spaces are limited to just 20 people. The workshop and hardware are free, but in return for the £10 booking fee, you will receive a copy of the book “Microcontroller Know How” by Mark Jones, G0MGX. You must be a ticket holder for the Convention to be able to take part. To find out more and to book your place, go to the RSGB website at rsgb.org/convention and choose the workshops and forums tab on the right-hand menu.

If you’re going to the National Hamfest on the 27th and 28th of September, why not try the RSGB Morse competency test? You don’t have to book in advance, just visit the RSGB village area. You can be tested at 10, 12, 15, 20, 25 or 30 words per minute so you don’t have to be a CW expert. If you pass the test, you’ll either receive a certificate on the day or it will be sent to you electronically shortly after. Eric Arkinstall, M0KZB is the RSGB Morse Competency Project Lead and he will guide you through the test process. If you don’t want to do the test you can still drop in to try Morse for the first time or pick up some hints and tips. It will be a busy event so whilst there will be headphones available, you’re welcome to bring your own if you prefer. Eric looks forward to seeing you at the event! If you have any questions, please contact Eric via [email protected]  

The RSGB Board Chair has announced that new Director Peter Bowyer, G4MJS will take on the Board Liaison roles for contesting and trophies. If you would like to contact Peter, his email address is [email protected]

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 22nd of August 2024

We had yet another week with a high solar flux and relatively calm geomagnetic conditions.

The solar flux index ended up at 239 on Thursday the 22nd, while the Kp index has been below 4 since Sunday the 18th. There are currently 11 active sunspot regions on the Sun’s surface and there is a 20% chance of a major X-class solar flare according to the NOAA Space Weather Prediction Center.

There are signs that HF propagation may be improving, but it will probably be another month or so before we see any large change. This is due to the summer doldrums that see the ionosphere harder to ionise due to a change in its chemical composition.

By mid to late September, we will start to see a change to autumnal conditions and DX will start to open up again on the higher bands. Having said that, there is still DX to be had. The N5J DXpedition to Jarvis Island in the Pacific Ocean proved that the DX is workable, but the path was mainly open to well-equipped stations with beams and linear amplifiers.

15m remains the best DX band and there are occasional openings on the 12m band. The 10m band may come into its own as we head into September and October.

According to the NOAA Space Weather Prediction Center, solar cycle 25 likely reached its highest sunspot number yet of at least 299 on the 8th of August. This may increase further, but we may be close to solar maximum.

Next week, NOAA predicts that the solar flux index will remain around 200 to 210. Geomagnetic conditions will depend almost entirely on the occurrence of coronal mass ejections, or CMEs. And, as we are at a particularly active part of the solar cycle, flares and CMEs are very prevalent.

And now the VHF and up propagation news from G3YLA and G4BAO

The overview for the coming week is that, although some fronts will affect the north and west at times, there are only a few that reach down to the southeast of Britain. This means that rain scatter is more likely in northern areas.

There will be weak high pressure over southern areas for much of the coming week and, although not enough for a full-blown Tropo event, conditions should be a little ‘up', especially for paths into the near continent or across the North Sea.

Meteor scatter is back to a more random approach since the broad peak of the August Perseids comes to an end. The solar conditions mean that auroras can be a possible element of operating excitement in the coming week. Remember to look out for a disturbed Kp index value of 6 or greater.

The last part of the sporadic-E season is playing out this week taking us to the end of the month. These 'last hurrahs' are usually characterised by QSOs of very limited duration on the 10m band, or perhaps up to 6m, and mainly over the southern half of Europe.

This usually favours southern UK stations but, notwithstanding the previous comments, some years have seen isolated Sporadic-E events in the first part of September. But they are certainly not reliable.

Moon declination is positive but still rising, reaching maximum on Wednesday, so long Moon visibility windows and high peak elevations continue. We are past perigee now, so path losses are increasing again. 144MHz sky noise is low but increasing to a moderate 500 Kelvin on Wednesday before falling back to low at the end of the week. 

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 15th of August 2024

Last week was notable for its auroral activity, high solar flux index and variable HF conditions.

Monday the 12th saw the Kp index rise to 7 as coronal mass ejection material struck the Earth, sparking visible aurora as far south as Cornwall. But by lunchtime on Tuesday things were back to normal with a Kp index below 2.

The rest of the week remained fairly settled with the occasional blip up to a Kp index of 4. Meanwhile, HF conditions have been variable with N5J on Jarvis Island in the Pacific being the main DX being chased. This has turned out to be a difficult catch for all but the better-equipped stations in the UK.

The operators are active on SSB, CW and FT8, using the SuperFox and Fox and Hound modes, and are working until the 20th of August. So, have a listen and give them a call.

The peak times are around 0500 to 1200UTC for a short-path contact, and around 1800UTC for a long-path contact. See jarvisisland2024.com for frequency details and the latest news.

Otherwise, the maximum useable frequency, or MUF, over a 3,000km path has been more than 18MHz and often 21MHz during daylight. Night-time MUFs have been more than 14MHz when there have been no geomagnetic disturbances.

Next week, NOAA predicts that the solar flux index will start at around 260 but decline to perhaps 210 as the week progresses. This is still enough for some good HF propagation. Predictions are less certain about geomagnetic disturbances, other than a rise on the 22nd of August.

Solarham.com predicts that a coronal mass ejection associated with an X1.1 solar flare last Wednesday will pass Earth by the 18th of August, so we may expect the Kp index to rise today.

And now the VHF and up propagation news from G3YLA and G4BAO

The period of alternating hot summer days and unsettled spells with rain or heavy showers looks like the recipe for the coming week. 

The weak ridges of high pressure could prove useful for some Tropo on occasion. In the summer months, Tropo is often more pronounced over nearby waters such as the North Sea and south across Biscay or the English Channel. But it can also feature overnight and, if we are lucky, may help with the 23cm UK Activity Contest on Tuesday the 20th.

These high-summer active fronts or heavy showers can be very good for rain scatter. Since temperature plays an important role in the intensity of summer thunderstorms, the resulting rain scatter is often best in the afternoon and early evening. On rare occasions, daytime storms can drift north from France to be over the UK during the night.

The Perseids meteor shower peak has passed now, with some good QSOs reported. It’s a broad shower and there should still be some worthwhile meteor input to play meteor scatter next week.

The recent solar conditions have produced a disturbed Kp index and there were some impressive visible and radio auroras from 10m up to 6m last week. It's worth watching out for a high Kp index above, say, 6 and be ready to listen for radio Aurora in the afternoon.

Lastly, the Sporadic-E season struggles on with varying degrees of success, but it's still very much a player for another two or three weeks. The upper air charts show that there should be some strong jet streams and thus potentially good sources of the turbulence required for Sporadic-E. Use the Propquest.co.uk  NVIS graphs to see if Dourbes in Belgium is showing any spikes.

Moon declination is negative but rising now. It won’t go positive until Wednesday, so short Moon visibility windows and peak elevation continue to increase. Wednesday is also perigee, the Moon’s closest point to Earth and when path losses are at their lowest. 144MHz sky noise is moderate to low over the coming week. 

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 8th of August 2024

Well, so much for the experts! NOAA predicted that the solar flux index would fall last week when it increased to a whopping 303 on Thursday the 8th.

But this high solar flux number was accompanied by a strong risk of solar flares, so it was not all plain sailing. We have had 15 M-class and two X-class solar flare events over the past three days and the threat remains high.

Coronal mass ejection activity on Wednesday resulted in NOAA and the Space Weather Prediction Centre warning of possible moderate G2 geomagnetic storming towards the later part of week ending the 11th of August. This could see the Kp index rise and the maximum usable frequency fall.

Hopefully, conditions will improve after the weekend.

Last week was a good one for HF propagation with a high solar flux index and low Kp index. The 10m band was open to Brazil in the late afternoon, and this appeared to be F2-layer propagation and not multi-hop Sporadic-E.

Meanwhile, the 15m band has perhaps been the DX band of choice with long openings to the Far East, at least on FT8, and North America at the same time. HF conditions should also improve as we move into September, but more on that closer to the time.

Attention now shifts to N5J on Jarvis Island, an uninhabited 4.5-kilometre-squared coral island in the South Pacific Ocean, about halfway between Hawaii and the Cook Islands. The DXpedition is active on all bands and their website at Jarvisisland2024.com can provide you with personalised propagation forecasts – let us know if you work them.

Using Proppy at soundbytes.asia or VOAcap at voacap.com, shows that 20, 17 and 15m  short-path seem to offer the best chance of working the DXpedition, with morning openings from around 0600 to 1000UTC. There is also a potential long-path opening between 1800 and 2000 UTC, with a possibility of the 10m band at 1900 UTC. Both are near polar paths and may be adversely affected by a high Kp index.

CDXC members with good stations have already reported QSOs with N5J on the 17m band using FT8.

Next week, NOAA predicts the solar flux index will be in the range of 185 to 240. Geomagnetic conditions will depend on whether we have more solar flares and coronal mass ejections, and the chance of those remains high.

An Earth-facing coronal mass ejection could send the Kp index soaring, and that will no doubt lead to reduced maximum useable frequencies and noisy bands. So, fingers crossed for more quiet geomagnetic conditions and low Kp indices!

And now the VHF and up propagation news from G3YLA and G4BAO

The summer tries to deliver but, overall, the pattern has a rather unsettled flavour to it for the coming week.

On the positive side, we see a transient area of high pressure crossing southern Britain over this weekend, ending today the 11th. This could give some Tropo conditions but, after this, the Atlantic westerly flow brings a succession of fronts and showers to most areas.

In terms of propagation, this suggests that rain scatter will have the best of it in the week ahead.

The Sporadic-E season remains a good fallback and surprised us in East Anglia mid-morning on Tuesday the 6th of August with 144MHz Sporadic-E propagation to YU, HA, 9A and LZ moving around towards Italy as the opening progressed.

All were workable with 100W and a white stick antenna on FT8. For the coming week, the jet stream activity will probably start by favouring paths to Scandinavia and the Baltic. Later in the week, a new jet stream will drive southeast into Iberia, opening up chances for paths to EA and CT.

The Perseids meteor shower this week will provide welcome new fuel for Sporadic-E and, as a result, like most years, we’ll see openings into the first week of September.

The meteor scatter highlight is the Perseids meteor shower, which peaks on Monday and Tuesday. So, there are plenty of opportunities to try a new mode or fill in some missing grid squares if you are already involved in meteor scatter.

Many websites explain what it's all about, but one to start you off is g7rdx.co.uk  Also, try looking for videos of meteor activity on SDR radios to get an idea of what it all sounds like.

The solar conditions lately have been rather disturbed. It would not be surprising if the Kp index was to suggest that aurora could be a possibility if it gets to 5 or higher.

Moon declination is negative and reaches minimum on Thursday the 15th, which means there will be short Moon visibility windows and low peak elevation. Path losses will decrease throughout the week and 144MHz sky noise is low over the weekend, but climbing to reach a high peak of over 3200 Kelvin on the 15th. 

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 1st of August 2024

We had another week of high solar flux but unsettled geomagnetic indices.

The solar flux index, or SFI, was above 200 from the 27th of July onwards. There was a worry that multiple coronal mass ejections, or CMEs, might push the Kp index up during the week. In the end, the Kp index didn’t rise above 5. But why was that?

The first of several CME eruptions was expected to pass Earth on the 29th of July. The solar wind speed increased from 330 kilometres per second to around 450 kilometres per second, but only a brief period of minor G1 geomagnetic storming was observed. The solar wind stream was fast, at more than 450 kilometres per second, but its frozen-in magnetic field was predominantly North-facing or neutral. So, it didn’t couple with the Earth’s magnetic field, and we ended up with a Kp index of only 5.

If we had had a south-facing interplanetary magnetic field or Bz it could have been much worse.

As it was, the ionosphere was affected on Wednesday the 31st of July. However, by 1830UTC things were back to normal, with a critical frequency of 7.4MHz, which gives a maximum usable frequency over a 3,000km path of around 21MHz.

Further disturbances on Thursday the 1st of August saw the Kp index rise to 5 again, but it was short-lived and only lasted for one three-hour period.

So, we are still in a period of high solar activity, with numerous M- and even X-class flares, coronal mass ejections and high sunspot numbers. With a cluster of sunspots rotating into view right now, it should be an interesting week ahead!

The SFI is predicted to fall next week, perhaps to the 180s or 190s. Meanwhile, HF propagation remains good at times, although we are still feeling the effects of the summer doldrums, with reduced daytime maximum usable frequencies.

Keep an eye on solarham.com for up-to-date geomagnetic information.

The 15m band is still the favoured daytime DX band, with occasional F2-layer openings on the 12m and even 10m bands. However, most 10m openings are still due to Sporadic-E.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather patterns that drive some of our radio propagation conditions are in the process of changing.

As we ended the previous week, there were still regions of high pressure near enough to southern areas for some useful Tropo across the North Sea, English Channel and south over Biscay. 

The slow change towards low pressure dominating the charts will be gradually extending its influence over the whole country as we move into next week, so less Tropo and more interest in rain scatter.

This has been available over some northern areas recently and from heavy thunderstorms in the south. It is probably going to be a useful mode for exploring the GHz bands in the coming week, particularly where heavy thundery rain occurs. 

Meteor scatter is also a worthwhile pursuit since we are still in the broad period of the Delta Aquariids meteor shower and that eventually blends into the August Perseids later in the month.

The solar conditions continue to be challenging and the Kp index has been high enough to make it worth thinking of checking for auroral conditions – either fluttery signals on the LF bands overnight, or perhaps auroral conditions on the VHF bands. The Kp index gets mentioned on all propagation websites these days, but spaceweather.com is a good source for that and much else too.

Sporadic-E is still worth checking out and, although the summer jet stream pattern is usually pretty weak, it is still there, and the position is perhaps a bit more northerly now than earlier in the summer. This means that paths towards the east to Scandinavia and the Baltic might be worth looking for, although other directions can still happen, of course.

Moon declination started to fall from Friday the 2nd, so Moon window lengths and peak Moon elevation will follow suit. With apogee on Thursday the 8th, path losses will be at their highest for the month. 144MHz sky noise is low until the evening of Saturday the 3rd when we see the Moon and Sun close in the sky until moonset on Sunday. After that, the sky noise is low.

And that’s all from the propagation team this week.

The news headlines:

• Two new Directors have been co-opted to the RSGB Board

When Paul Nichols, M0PVN resigned as an RSGB Director in May, it created a vacancy on the Board. The Board decided that it was in the Society's interests to expand the Board to nine people to help implement the Society’s strategic priorities. Under Article 37 it has co-opted Peter Bowyer, G4MJS and Peter Ransom, M0SFZ as Directors to serve until the 2025 AGM. Peter Ransom recently passed his Full licence so that he could build and tinker with RF equipment, to add to his ongoing interest in writing amateur radio software and designing his own PCBs. He has a passion for technology and communication and has had a career that combines technical expertise with strategic vision. He hopes to use that knowledge and experience to help the Board to ensure that the Society remains relevant to the amateur radio community. Peter Bowyer has been in and around IT all his career and currently helps organisations with their Agile development strategies. He has been licensed for 45 years, but says he is still learning new things. He's an avid contester, having served on the VHF Contests Committee, he has written a column for RadCom and is a past chair of the UK Six Metre Group. The RSGB welcomes them both to the Board.

The RSGB is delighted to announce the co-option of two Regional Representatives. Peter Lowrie, MI5JYK is based in Region 8 and Brian Woolnough, M5ADQ in Region 12.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of July 2024

We had yet another week of high sunspot numbers and low geomagnetic disturbances, but will it last?

We dodged a bullet last week after a weak coronal mass ejection, or CME, on Tuesday the 23rd failed to generate a geomagnetic storm. This was from a faint halo CME observed on Sunday, which was much weaker than expected when it hit Earth.

A further M2.4 flare, near the eastern limb on Tuesday, produced a coronal mass ejection, but that was directed away from Earth.

So, we ended the week with a Kp index that never rose above 2, despite up to 19 M-class solar flares occurring. Our luck must run out some time!

The main HF DX this week has been the K8R DXpedition on American Samoa. This has been workable on all bands from 20 to 10m, especially using FT8. They have been trialling a new Super Fox mode on FT8. If you are interested in using this mode, you will need the latest version of the WSJT-X software.

Daylight maximum usable frequencies, or MUFs, over a 3,000km path have reached more than 24MHz, with 28MHz available at times on some paths. This will, no doubt, improve as we head towards the autumn.

Nighttime MUFs over a similar path length have exceeded 14MHz and often reached 18MHz at times. Make the most of the nighttime openings as they will die off as we head towards the end of the summer.

Next week, NOAA predicts the solar flux index will be in the range of 165 to 175 and the Kp index will be a maximum of 2 all week. As ever, this will be dependent on any solar flares and associated CMEs. A CME could easily push the Kp index up and the MUF down.

Four sunspot groups have just rotated into view so keep a close eye on them on solarham.com  At least one is classed as “growing” and could be a contender for trouble over the next week by way of solar flares and CMEs.

And now the VHF and up propagation news from G3YLA and G4BAO

The area of high pressure which develops over this weekend will bring the prospect of Tropo conditions at the start of the new week.

The high will drift slowly east towards Denmark by midweek but could still provide the chance of Tropo conditions across the North Sea until Wednesday.

Meanwhile, a weather front will reach northwest Scotland on Monday and edge slowly south whilst a small thundery low develops near the southwest of Britain. This combination will bring a gradual transition to more unsettled weather with a chance of rain scatter on the GHz bands for the second half of the week.

The Delta Aquariid meteor shower is active from the 12th of July to the 23rd of August. With no noticeable peak, it is expected to reach its maximum rate of 25 per hour on or around the 30th of July.

We should have more than just random meteors to use for meteor scatter operation, so it's worth trying meteor scatter on the VHF bands. Also, given clear skies and darkness over the next few weeks, it's worth having a look out for them with the naked eye or photographically.

This extra input of meteors may well improve the prospects for Sporadic-E, which have perhaps seemed a little less than enthusiastic recently. Meteor debris from meteor showers, or random meteors, provides the fuel for Sporadic-E. These ionised trails in the E region above 100km can be affected by wave motion caused by jet streams much lower down at around 10km.

Fortunately, there are a number of useful jet streams on the forecast charts for next week with a slight preference for paths to Scandinavia and eastern Europe.

Moon declination is positive and rising, reaching maximum on Thursday the 1st of August, so Moon windows are long with high peak Moon elevation. We passed perigee on the 24th so path losses are on the increase. 144MHz sky noise is low to moderate all week.

And that’s all from the propagation team this week.

On Thursday the 25th, the 80m Club Championship Data Contest runs from 1900 to 2030UTC. Using RTTY and PSK63 on the 80m band, the exchange is signal report and serial number.

The IOTA Contest runs from 1200UTC on Saturday the 27th to 1200UTC on Sunday the 28th of July. Using CW and SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report, serial number and IOTA reference.

On Sunday the 28th, the UK Microwave Group 5.7 and 10GHz Contest runs from 0600 to 1800UTC. Using all modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator.

 Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 18th of July 2024

We had another great week in terms of HF propagation. The solar flux index was at a remarkable 224 on Thursday the 18th, and the Kp index had been consistently in the ones and twos all week.

It doesn’t get much better than this, HF-wise, although it's a shame it's not autumn with the associated good HF autumnal propagation.

Given that we are in the summer HF doldrums, there has been a lot of DX on the bands. 15m has been very good during late afternoons, and open to all continents, with Australia, Asia, Africa, North America and South America all workable on FT8 at the same time.

On Thursday the 18th, there were 17 active sunspot regions visible, which contributed to the high solar flux index. Two X-class solar flares brought short-term solar fadeouts on the 14th and the 16th, but any associated coronal mass ejection has been mainly directed away from Earth.

For those new to HF propagation, this is good news. Remember, a high solar flux index is generally good, while a high, perhaps more than four, Kp index is generally bad.

Daytime maximum usable frequencies, or MUFs, over a 3,000km path have been consistently above 21MHz. Nighttime MUFs have been more than 14MHz, and often 18MHz, at times.

But will this continue? Probably not.

Of the 17 visible sunspot groups, six are classed as ‘growing’. There have been coronal mass ejections from sunspots on the edge of the Sun, but they have not been Earth-directed. But, as these spots rotate to be Earth-facing, a coronal mass ejection could be more problematic.  

Next week, NOAA predicts that the solar flux index may fall, perhaps into the 170s to 180s range.

The Kp index is predicted to be around 2, but if we do have an Earth-facing coronal mass ejection that could easily climb to 4 or 5, with an associated drop in the maximum usable frequency.

So, will it be another week without a high Kp index? Maybe that is too much to hope for!

And now the VHF and up propagation news from G3YLA and G4BAO

Last week ended with a decaying high over Germany and fronts pushing in across western Britain. With such warm air over the UK at first, even temporarily, there will be a reasonable chance of Tropo over nearby cooler waters around our coasts, especially along the English Channel and southern North Sea.

Incidentally, for anyone taking a VHF rig with them on holiday to the Mediterranean resorts, you can expect typical summer semi-permanent, very strong maritime Tropo ducts over any sea path to neighbouring islands or countries.

Returning to the UK, we have a series of fronts and lows lined up for the coming week. In summer months these can often have a showery element to them, so expect some heavy rain and thunder at times, but at least there'll be rain scatter to make up for it!

Meteor scatter is again a random experience, with no major showers this week. Try around, or just before, dawn for best results. The solar conditions have been all over the place with flares and weak auroral responses, but nothing dramatic for VHF radio.

Sporadic-E, on the other hand, has done fairly well for digital mode activity, especially for transatlantic paths, but is slightly subdued where higher signal levels are required for SSB and CW. Although the weather is expected to be unsettled, the jet stream activity is less widespread than recently. If anything, the western side of Europe seems in a better spot with quite good options for paths to Iberia. Remember, most years will see activity into the first week of September, so don’t give up yet.

The Moon is at minimum declination on Friday the 19th so we start the week with short Moon windows and falling path losses as we approach perigee on the 24th. Perigee is the point at which the Moon is closest to the Earth. 144MHz sky noise starts very high but declines to medium next week.

And that’s all from the propagation team this week.
