Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 7th of November.

We had another week of high solar flux and good conditions on HF.

Solar activity remained at high levels thanks to an impulsive X2.3 solar flare around active region 3883 at 13:40 UTC on the 6th of November, but the event was not responsible for a coronal mass ejection (CME).

The Kp index remained below 4.5 all week, with a solar flux index in the range of 240-260. That was more than enough to keep the ionosphere very active.

A recent report on spaceweather.com  suggested that the solar cycle may have peaked in the Sun’s southern hemisphere but may still have a way to go in its northern hemisphere.

It's usual for there to be two peaks in a solar cycle as the two hemispheres are seldom synchronised. We will have to wait and see, but it could mean another three to six months of high SFI numbers as the northern hemisphere catches up.

A solar filament located in the southwest quadrant erupted on the 7th of November. A coronal mass ejection, or CME as it is also known, occurred but appeared to be off the Sun-Earth line, so no major impacts are expected.

A sunspot group turning into view from off the southeastern limb has been assigned active region 3889 and is producing M-class solar flares. The probability of further M-class flares stands at 80%. Meanwhile, the risk of an X-class flare currently stands at 35%.

A coronal hole is currently Earth-facing and could cause some disruption sometime around Saturday 9th.

The solar proton flux has decreased to normal levels, so polar paths should now be unaffected.

Next week, NOAA predicts that the SFI could decline into the range of 165-185. Geomagnetic disturbances are forecast for the 11th and 12th, and again on the 15th, with the Kp index predicted to reach four.

Meanwhile, we do urge you to get on 10 metres, which is currently experiencing some fine DX openings. This month and next will probably give the best chance of good 10-metre propagation for a while.

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

Another week has just passed with daily F2-layer propagation on 50MHz providing morning openings to Southeast Asia, and the Americas in the afternoon. Expect more in the coming week. 

The current spell of high pressure has had a good run with some excellent Tropo conditions, with the best DX along the side of the high pressure.

This weekend will see the high finally giving way as weak Atlantic fronts move in from the west. This will soon be replaced by a new high building in the colder air behind the weekend fronts. It may look like Tropo should come back, but this high may be less productive.

The major change of weather pattern comes before mid-week, when it may turn more unsettled as low pressure moves closer to eastern areas from the North Sea. This general move towards more unsettled conditions will continue through the end of the week.

In terms of propagation, good Tropo will be replaced by some patchy rain scatter opportunities for the GHz bands from about the middle of next week.

Staying with scatter modes, meteor scatter looks promising with the Taurids peaking on Tuesday the 12th and the Leonids due to peak on the following weekend on Sunday the 17th.

The solar conditions continue to offer chance occurrences of aurora due to solar flares or CMEs so, as usual, keep a watch on the Kp index going above Kp=4.

An occasional reminder of the possibility of out-of-season Es for the digital modes is timely. Recently the critical frequency of the Es layer has reached 7MHz on the Dourbes ionosonde plotted on www.propquest.co.uk  and in theory, this would be good enough for a 6m band path.

For EME operators, Moon declination is negative but rising, going positive again on Tuesday the 12th. Path losses are falling as we approach perigee next Thursday the 14th. 144MHz sky noise is moderate to low this 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 31 October 2024.

Last weekend’s CQWW SSB contest showed just how good autumnal HF conditions can be. Many contestants worked more than 100 countries or DX entities on each and every HF band.

With a solar flux index of 238 on Saturday and 246 on Sunday, plus low Kp indices all weekend, it was about as good as it could get. There were two three-hour periods where the Kp index hit four and 4.33, but it was otherwise in the ones and twos.

An X-class solar flare occurred on Saturday the 26th at around 07:15 hrs UTC, but this had little effect and the MUF over a 3,000km path was back above 28MHz quite quickly.

The rest of the week saw numerous M-class and C-class solar flares occur and a Kp index that did get up to four at times, but once again the MUF remained above 28MHz during daylight for most of the time.

Interestingly, there have been times when the critical frequency over the UK has hit 14MHz, making 20m almost a local chat band via Near Vertical Incidence Sky Wave or NVIS communications! These openings may be short-lived so make the most of them should they occur.

Nighttime critical frequencies have generally been around 4.5-6MHz, meaning a MUF over a 3,000km path over 14MHz in the first half of the night and around 10-12MHz in the second half.

The solar proton flux has been above the 10MeV warning threshold but is now falling as of Thursday 31st. This may improve signals that pass through the polar regions, such as the UK to the far west of Canada and Alaska, and the UK to Japan.

Next week NOAA predicts that the SFI will start at around 240, but perhaps fall to around 195-200 as the week progresses. ESA predicts that the solar wind speed could increase around November 4th and could cause disruption.

As always, we are at the mercy of solar flares and CMEs, which could disrupt HF propagation, so we recommend keeping an eye on solarham.com for daily updates.

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

The Autumn Equinox period continued to bring F2-layer propagation to 50MHz with almost daily morning openings to VK and JA and afternoon openings to the Americas for some.

Stations in the far South and West of the island were favoured. Side scatter in the Indian Ocean brought the JAs on a 90-degree beam heading, an effect noted at previous sunspot maxima.

The autumn is typically a time for quiet settled weather, a season of mist, and this is where we are going for the period through to the end of next week. It's worth a couple of reminders of how it all works since, although it's likely to be pretty much the same ‘big picture’ of dominant high pressure, there will be subtle differences.

Firstly, there are two types of high pressure; one that builds in warm air and the other in cold air. The warm air version is the current offering, and this means quite cloudy conditions at times with moist air below the temperature inversion and very dry air above the inversion.

Second, the quality of the ducting is determined by the change of the refractive index across the inversion and a large part of the refractive index change comes from a contrast of moisture, so signs of cloud and/or fog moisture are good omens for a lift. We may swap over to a cold air high later next week, which could lessen the Tropo quality.

Meteor scatter prospects are on hold pending the Leonids meteor shower, which peaks mid-November. A dominant high pressure means that rain scatter is not likely to be a big player for the GHz bands next week.

There is a possible heads-up for aurora since the solar conditions still offer chances for the Kp index to rise – anything over Kp=4 is worth a longer look – and don’t forget that ‘watery’ signals on the lower HF bands such as 40m and 80m are also a good sign.

For EME operators, Moon declination reaches a minimum (that is, maximum negative declination) next Tuesday when the Moon only reaches nine degrees peak elevation and is only above the horizon for six hours between 1200 and 1800hrs. Path losses, on the other hand, are falling all week.

144MHz sky noise is moderate to high, peaking at more than 3,000 Kelvin on Tuesday the 5th before dropping back to moderate levels.

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

• The RSGB releases a snapshot video of the exciting Girlguiding ISS contact

On the 5th of October, in her first official engagement as Girlguiding Patron, Her Royal Highness The Duchess of Edinburgh joined 100 excited Brownies, Guides and Rangers in making a live amateur radio contact with the International Space Station. The event was organised by The Radio Society of Great Britain and Amateur Radio on the International Space Station, or ARISS as it is usually known, in collaboration with the UK Space Agency, Girlguiding Surrey West and Brooklands Museum’s Innovation Academy programme. The aim was to promote the engagement and involvement of girls and young women in science, technology, engineering and mathematics. Everyone had a fantastic day and after the contact, the girls enjoyed a variety of STEM activities including making Snail Morse keys, playing Morse battleships, learning about the CubeSat Simulator and making stomp rockets. The RSGB has created a short video snapshot of the day which you can see on its YouTube channel at youtube.com/theRSGB – take a look!

The latest episode of the ICQ Podcast is available to listen to online and features RSGB Propagation Studies Committee Chair, Steve Nichols, G0KYA. During episode 441 Martin Butler, M1MRB talks to Steve about propagation and how the sunspot cycle has taken off to impact conditions positively. They also discuss Ham Radio Science Citizen Investigation, which is also known as HamSCI, a collective that enables university researchers to collaborate with radio amateurs in scientific investigations.

If you are thinking of taking an amateur radio exam before Christmas, there are two important dates you need to be aware of. The last date you can take an exam at a club, whether online or on paper, is Friday the 13th of December. If you want to take an exam online at home, the last date you can do that is Friday the 20th of December. The RSGB Exams Team will, where possible, post-out exam results before HQ shuts over Christmas and New Year. Exams will resume on Monday the 6th of January 2025 and the booking system will be available over the festive season so you can book exams for January onwards. You can book online on the RSGB website at rsgb.org/exampay

On Friday the 18th of October the RSGB, Mill Hill School and a team of radio amateurs in New Zealand took part in a special celebration to mark the centenary of the first successful two-way trans-global communication between radio amateurs in the UK and New Zealand. The original contact between Frank Bell, 4AA in New Zealand and Cecil Goyder, 2SZ in Mill Hill School in North London was re-enacted at the school on a wavelength as close as possible to the original. Members of Goyder’s family watched the re-enactment and chatted to pupils. As part of wider celebrations for the day, the school put on activities including a build-a-radio workshop. Students at the school showed significant interest in amateur radio, with several students signing up to be part of a new radio club that will be set up by the school’s physics teacher. The overall event was led by RSGB Life Vice-President Don Beattie, G3BJ who said that he was delighted by the success of the event and that it had allowed pupils to learn how ground-breaking that first radio contact was with New Zealand. Call sign G2SZ was operational for four days surrounding the centenary, during which operators achieved approximately 1,250 contacts. To find out more about this unique celebration go to www.gb2nz.com and search for ‘GB2NZ re-enactment’ on the RSGB website.

The Memorial Day QSO Party is an activity providing participants with an opportunity to honour amateur radio operators who are now Silent Key. The event is being sponsored and managed by the First Class CW Operators’ Club and is open to all licensed amateurs. The event begins at 0900UTC on the 1st of November 2024 and ends at 0859UTC on the 2nd of November. More information is available at g4foc.org or by emailing [email protected] or [email protected]

Ofcom has notified stakeholders that the next release of its licensing service will be delayed due to issues that have arisen during software development. According to the Ofcom website, the delays have impacted Phases 2 and 3 of the planned changes to the amateur radio licensing framework.

 Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 24th of October 2024

Last week’s solar conditions couldn’t have been much better. We had a week of high solar flux indices, relatively calm geomagnetic conditions and, other than an X-class solar flare, not much else to report.

The solar flare originated from active region 3869 and reached a strong X3.3 in the early hours of October 24th. This event was associated with a coronal mass ejection, or CME, based on solar dimming following the event, but because the flare location was located off the east limb, it was directed mostly away from Earth.

Once again, all the sunspots are in the southern hemisphere, but activity appears to be growing. This could spell trouble over the next week.

This weekend, the 26th and 27th, the CQ Worldwide SSB contest is taking place and conditions should be excellent, with a combination of high solar flux and autumnal HF conditions.

Maximum usable frequencies, or MUFs, are generally higher than 28MHz from dawn until dusk. Nighttime MUFs over 3,000km are still just above 14MHz, although you might get better results by dropping down to 10MHz if the 20m band doesn’t work for you.

Next week, NOAA predicts that the solar flux index may rise again, perhaps hitting 185 as we enter November. However, this current bunch of sunspots, which are rotating to be Earth-directed next week, appear more active and we could see more solar flares and CMEs, which could throw a spanner in the works.

A solar flare could impact the ionosphere by increasing D-layer absorption, for up to an hour or so, and possibly launch a coronal mass ejection.

If a CME hits the Earth, expect the MUF to plummet, at least for a day or two until the ionosphere recovers.

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

The Autumn Equinox period brought some amazing ionospheric propagation to 50MHz on Thursday last week with stations in the UK working morning paths to VK, JA, DS and XV among others.

Typically for 50MHz DX, the skip zones were sharp and moved rapidly. Stations even a few kilometres apart experienced very different signals and paths. Those with a low noise floor had a huge advantage as signals were generally weak in the UK and only good for FT8. However, some reports of a VK station at +5 bucked this trend.

Next week will offer some reasonable Tropo conditions, although not without some occasional interruptions from weak frontal systems, especially in the far southwest and the far northwest of Britain. It’s not clear if these represent good rain scatter options, but they are more likely to temporarily curtail any Tropo for a while.

The solar conditions continue to feed the occasional aurora alert our way, so it’s always good to monitor the Kp index for signs of it increasing above 4. It won’t always go on to produce a radio aurora, but it's worth keeping an eye on things.

The meteor scatter prospects continue to be elevated by the decline of the Orionids, which peaked on Tuesday the 22nd, and the Taurids, which are a very low-rate shower, but technically cover a broad period into December. The Leonids are the next major shower, but that doesn’t peak until mid-November.

Lastly, looking at the out-of-season Sporadic-E prospects, there are always days with minor enhancements of the critical frequency of the Sporadic-E layer, as shown on the propquest.co.uk graphs. Certainly, there are stronger jet streams available in the autumn and winter, but other elements of Sporadic-E are not so favourable. It’s usually a very marginal outcome at best, but good enough for the 10 or 6m bands and mostly for digital modes such as FT8. 

It could well be that trans-equatorial propagation, or TEP, is a more fruitful venture.

For EME operators, Moon declination is positive, but falling, going negative on Tuesday the 29th. Path losses are rising, reaching a maximum at apogee on the morning of Wednesday the 30th. 144MHz sky noise is low until Friday the 1st of November when the Sun and Moon are close in the sky.

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

The news headlines:

• The RSGB welcomes your feedback on its 2024 Convention

The RSGB’s 2024 Convention took place last weekend and brought together hundreds in person, as well as many more from across the globe who watched via the livestream. The Society is already receiving an overwhelming amount of positive feedback, but if you did attend the Convention and haven’t yet completed the feedback form, please go to rsgb.org/feedback and share your thoughts. If you watched the livestream the Society would also love to hear your feedback. Please visit rsgb.org/livestream-feedback and let the team know what you think of the online event. The feedback forms will be closed at the end of October. The live streams for both days will remain available for everyone to watch, so if you’d like to catch up on the selection of presentations that were aired, go to the RSGB website and search for ‘Convention 2024 Livestream’. As well as talks from the weekend, you’ll find exclusive special interviews and pre-recorded videos.

Today, the 20th, is the last day of Jamboree on the Air, also known as JOTA. The event promotes friendship and global citizenship and is a brilliant celebration of amateur radio among the Scout Association. The Society has compiled a list of Scouting groups that are involved with the annual event and has shared it on its website. The list is available by going to rsgb.org/jota and choosing the ‘JOTA Stations on the Air’ link on the right hand side of the page. The RSGB would love to see your photos of Scouts getting involved with JOTA, so tag @theRSGB and also use #JOTAJOTI to be involved in the conversation on social media. If you’re not involved with a JOTA station do listen out and encourage the young operators on the air. There will be a report in RadCom so please send details and photos from your event to [email protected] by the 15th of November.

Following the recent appointment of two Youth Champions for schools and universities, the RSGB is keen to expand the team. The Society is looking for a Youth Champion for scouts, guides and cadets, and another to lead activities and create resources to support young people once they have gained their Foundation licence, motivating them to try new things within amateur radio. The four Youth Champions will work closely as a team, as well as with the RSGB Board Liaison, Ben Lloyd, GW4BML and the RSGB Outreach Team. Together, the Youth Champions will also create a youth team and run a net or sked to involve all youngsters. Do you have what it takes to engage with young people and support them on their amateur radio journey? Another part of each Youth Champion’s role is to give input and support for current activities, such as promoting and participating in Youngsters on the Air Month each December. If you are proactive, experienced at managing your own time efficiently, a good leader who can build relationships and mentor young people, and you are passionate about growing the number of young people involved in amateur radio, then one of these roles could be for you! Take a look at the youth activities on the RSGB website at rsgb.org/youth and see some of the great things that are happening already. If you’re interested in being part of the team, contact Youth Board Liaison Ben Lloyd, GW4BML via [email protected]

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 17th of October 2024

The past week has been characterised by a low geomagnetic Kp index and excellent conditions on HF, including the 10m band. With a solar flux index between 168 and 195, and a Kp index that never rose above 4, conditions have been better than the previous week, which suffered from the bad effects of solar flares and coronal mass ejections.

This came as NASA, NOAA and the International Solar Cycle Prediction Panel announced that the Sun has reached its solar maximum period, which should continue for the next year.

The announcement was not unexpected, and the exact period of maximum activity won’t be known for some time. But it was a wake-up call for radio amateurs to get on the bands and make the most of the conditions!

NOAA anticipates additional solar and geomagnetic storms during the current solar maximum period and during the declining phase of the solar cycle.

The solar flux index fell from its 200-plus highs to be in the 160 to 195 range last week. But this was still more than enough to keep the ionosphere running. Maximum usable frequencies over a 3,000km path have been consistently over 28MHz during daylight, falling to around 11MHz overnight.

Next week, the Space Weather Prediction Centre thinks the solar flux index will rise into the 200s again, but we may also get some geomagnetic disturbances, namely on the 22nd and 23rd when the Kp index might rise to around 4.

Meanwhile, October can be one of the best months for HF propagation with good 10m band openings to Australasia in the morning and North and South America in the afternoon.

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

The current unsettled spell of weather seems likely to continue into next week and is not atypical at this time of year. We should expect a more changeable pattern around the autumn as the main polar front jet stream migrates south across the UK into its winter state over the Mediterranean.

That said, there may well be some brief interludes when the extended region of high pressure across Europe influences conditions over the British Isles, more specifically the southeastern corner.

This is shown by some models around midweek for potential Tropo from southeastern England into the continent or across the North Sea to northern Europe and southern Scandinavia.

The obvious mode to result from this unsettled weather will be rain scatter and it is probable that the GHz bands will enjoy this period of weather.

Meteor scatter in October has a few showers to maintain interest. The Orionids and the Taurids are both active during the coming week. In fact, the Orionids, associated with the comet Halley, peak on Monday and Tuesday.

Just a final note about Sporadic-E, which is ‘out of season’. Remember that there are no ‘zero Sporadic-E months’ and recent indications have tended to show the response of raised critical frequencies of the Sporadic-E layer occurring around the middle of the day on the propquest.co.uk NVIS graphs.

You may also see peaks earlier in the day around dawn, which is the peak time for meteor input. Beware, it is easy to get hooked on out-of-season Sporadic-E hunting!

For EME operators, Moon declination is positive and rising. Path losses are rising again after the perigee on Thursday the 17th. So, we have increasing peak Moon elevations and longer Moon windows until Tuesday the 22nd. 144MHz sky noise is low to moderate for the rest of the week.

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

Sunday the 13th of October

The news headlines:

• The RSGB 2024 Convention is taking place this weekend

The RSGB Convention has been in full swing this weekend. If you haven’t been able to attend, the RSGB has provided a packed live stream on each day and those live streams are available for anyone to view. Full of presentations, interviews and videos to inspire you, this is another way to enjoy your Convention, in your way. Either go directly to the RSGB YouTube channel or head over to rsgb.org/livestream to see the programme of presentations and the links to the livestreams.

The RSGB is delighted to announce the appointment of two new volunteer Youth Champion roles. Chris Aitken, MM0WIC will be the RSGB’s School Youth Champion and Rhys Williams, M0WGY/AJ6XD will be the University Youth Champion. Chris is a Computing Science teacher at Wick High School, Caithness. Since 2023, Chris has been running the Wick High School Radio Club, GM0WHS, providing students with a wide range of experiences in amateur radio. He has four students who have passed their Foundation licence exam and are now taking on leadership roles within the club and assisting the latest cohort in their studies. He is also a member of the RSGB Outreach Team. You can contact Chris via [email protected]  Rhys represented the RSGB at the Youngsters on the Air Camp in Prague this year. He sent back daily reports on his activities which you can still see on the website under the summer camps tab at rsgb.org/yota  He is starting a PhD in Aerospace Engineering at the University of Oxford and is keen to help the RSGB support the growth of amateur radio in universities across the UK. You can contact Rhys via [email protected]  Ben Lloyd, GW4BML is the Board Liaison for youth activities. He said that he welcomes Chris and Rhys to their new youth volunteer roles and looks forward to working closely with them in the future to attract and grow RSGB youth membership. He explained that the three of them have already had some positive conversations and shared some good ideas, which they will be putting into place over the coming months.

This week marks the centenary of the world’s very first trans-global two-way radio communication. On the 18th of October 1924 Frank Bell, 4AA, from New Zealand, and Cecil Goyder, 2SZ, from North London, changed how we communicate forever by making contact on amateur bands. To commemorate this historic contact, special callsigns will be active, and awards and QSL cards will be available for those who make contact with these special stations. GB2NZ and ZM100DX have already been active since the start of the month. Starting tomorrow, until the 20th of October, calls reflecting Goyder’s callsign, G2SZ, and Bell’s, ZL4AA, will be active. This will include activity here in the UK from Mill Hill School in North London which is the original location from which Goyder made his contact. On Friday the 18th of October, radio amateurs will also be recreating and re-enacting the first contact between Goyder and Bell. It is hoped that the QSO will be made on a wavelength close to that used in 1924. To find out more about this unique celebration go to gb2nz.com

YOTA Month is just around the corner, and the RSGB is looking for volunteers to host the GB24YOTA callsign throughout the month of December. As in previous years, schools, clubs, guide and scout groups and also individuals are invited to host young radio amateurs whilst they operate with the callsign. Each day during the month has been split into a number of operating slots that you can book. In recent years, this system has allowed many more youngsters to get on the radio throughout the month. You can see the operating calendar by visiting QRZ.com and searching for GB24YOTA. Operators should be below the age of 26. Those who do not hold a Full amateur radio licence should be supervised by an appropriate Full licensee whilst operating. The RSGB is pleased that previous activators have already reached out to book their operating slots but there are still many more up for grabs! To book an operating slot or for more information about YOTA Month, please email Jamie, M0SDV at [email protected]

 Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 9th of October 2024

What a difference a week makes when it comes to HF propagation!

This last week has been characterised by solar flares, coronal mass ejections, or CMEs for short, and an elevated Kp index. Put together, this has resulted in dire conditions on HF, reminiscent of a solar minimum.

A visible aurora was seen from the UK once again after the Kp index hit 7.33 on the 8th of October.

Numerous CMEs have hit the Earth and the solar proton flux has risen, resulting in a moderate S2 radiation storm as particles blasted away from the flare site.

This means poor trans-polar paths until the solar wind abates and the storm settles.

Maximum usable frequencies have been badly affected and struggled to get much past 14MHz over a 3,000km path on the 8th of October. Geomagnetic storms were also forecast for Thursday the 10th and Friday the 11th.

That’s a shame as, before the CMEs hit, HF had been humming with a lot of DX on the 28MHz band and many five-watt beacons romping in from the USA.

Next week, NOAA predicts that the solar flux index may drop back into the 170s, but it’s anyone’s guess as to how geomagnetic conditions will pan out.

We have had three X-class solar flares over the past week and on Wednesday the 9th the probability of another X-class solar flare was estimated at 30% and an M-class event at 75%. So, it may be a case of ‘batten down the hatches’ on HF until the storm conditions pass.

This is not uncommon at this point in the solar cycle and unsettled conditions are likely to continue as we move along the downward portion towards the solar minimum.

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

The current spell of unsettled weather is probably going to flip into high-pressure mode a couple of times during the coming week. The first of these will be today, the 13th, and through the first half of next week.

However, by Wednesday the next change back to low pressure should be with us, closely followed by another attempt to build high pressure later in the week. 

This offers something for everyone with prospects for rain scatter on the GHz bands and the possibility of Tropo.

The prospects for meteor scatter are also good with October offering several useful meteor showers.

While 50 and 70MHz are the best for the mode, look at 144.360MHz in MSK144 digimode. Or, if it’s a shower peak, 144.200MHz, the SSB meteor scatter calling channel, to see what’s around.

The solar conditions continue to behave like a solar maximum and, with several recent powerful flares and CMEs to stir things up, we should continue to check the bands for signs of aurora. 

The recent RSGB CW 80m Autumn Series Contest on Monday the 7th of October was about as auroral as it gets with a strong flutter on signals and a challenging hour and a half for participants – so not just an effect for VHF. 

The RSGB 1.3GHz UK Activity Contest coming up next week on Tuesday the 15th may be on the changeover from high pressure to low. Tropo might be limited to eastern areas for paths across the North Sea to northern Europe.

For EME operators, Moon declination is still negative but will rise to positive by Tuesday night. Path losses are falling towards a minimum at perigee on Thursday the 17th.

So, we have increasing peak Moon elevations and longer Moon windows with the lowest loss for the coming week. 144MHz sky noise is low for the rest of the week.

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

The news headlines:

• The deadline for advance tickets for the RSGB 2024 Convention is tomorrow, Monday the 7th of October

The theme for this year’s RSGB Convention is “Your Convention, Your Way” and the Society is providing a range of activities and presentations as well as different ways to get involved. There is still just time to buy your tickets in advance, but hurry as advance sales for attending the Convention or the dinners closes tomorrow, Monday the 7th of October. You will be able to buy a Convention ticket on the door but not at the discounted rate that is available now. At the event, there will be a varied programme of presentations regardless of your amateur radio interests or experience, as well as practical workshops and Morse competency tests. You’ll also find a room full of special interest groups to chat to who could inspire you to try something new! If you’re unable to travel to the Convention, a small number of presentations will be live-streamed and will be available on the RSGB YouTube channel without the need to pre-register. The RSGB has released two ‘Convention Chat’ videos recently and will be releasing two more over the coming week, so find out what others think of the Convention and see who you might bump into in the bar! For full programme details and speaker information and to book in advance, go to the RSGB Convention web pages at rsgb.org/convention

Did you take part in National Coding Week this year? The RSGB had nine activities to inspire you to take part, including two new worksheets developed by the Society’s Outreach Team. Whether you took part by yourself, at a club night, or with friends and family, the RSGB would love to hear from you. To be included in the RadCom December feature on National Coding Week please send a summary of your activity, along with any photos, to [email protected] by the 17th of October. The worksheets will remain on the RSGB website for people to try, so if you would still like to have a go head over to rsgb.org/coding and get involved.

The next RSGB Tonight@8 live webinar is tomorrow, Monday the 7th of October. Ian White, GM3SEK will present ‘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. It may sound rather technical, but with some explanations from Ian, aircraft scatter might soon feel very easy. During the talk, Ian will consider how aircraft scatter works, and if it’s so useful, why haven’t we heard more about it? Join the webinar live at 8 pm 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

grid.radio is a web application born out of the frustration that Rose, 2E0RXO and many others experienced during spontaneous, often unplanned, Parks on the Air activations. During busy moments, someone would inevitably ask for a Worked All Britain square or another reference that she wasn’t prepared for. There wasn’t a single, simple resource to quickly gather this information with a fast-loading, modern interface. Many websites would spend more time loading advertisements than displaying the necessary information, delaying communication and increasing the pending pile-up. After several months of facing the same issue and finding herself still unprepared, Rose, a Computer Science graduate, decided to solve the problem with code. She created a fast, free web app that can be installed on the home screen of any phone or tablet or accessed on a desktop computer for pre-activation planning. You can also share links so others can easily find out where you are operating from. Once installed, the app will even work without a data connection. Development is ongoing, with feedback from all amateur radio operators welcomed via the contact details on Rose’s QRZ.com page. To learn more about this useful web app visit grid.radio

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 3rd of October 2024

In the first week of October, the 10m band began to show what it is capable of. With a solar flux index in the high 200s and calm geomagnetic conditions, DX was plentiful.

Nick, VK9DX on Norfolk Island was audible on SSB all morning on Wednesday the 2nd and only wanted to work G stations. This made him popular in the UK, but less so in other countries!

Vlad, 5H1WX, on Mafia Island, Tanzania, was another strong signal on the morning of the third. Meanwhile, the 3D2V Rotuma Island DXpedition near Fiji on the 10m band using FT4 was another catch for many people.

The Kp index managed to remain low for the first half of the week, but there were warnings that a coronal mass ejection, which was attributed to the X7.1 solar flare on the 1st of October, might upset things later in the week.

With a good spread of sunspots, mainly in the Sun’s southern hemisphere, there could be more flares over the coming days.

Scott Mcintosh, the solar physicist who predicted a busier than average Cycle 25, has now questioned whether we are past solar maximum. The fact that there are now fewer sunspots in the Northern Hemisphere suggests that we may be past the peak, but only time will tell.

Meanwhile, NOAA predicts the solar flux index may decline towards the 200 mark next week. The Kp index is predicted to go to 4 this weekend. With four of the ten active sunspot groups now classed as growing, we may expect further solar activity and geomagnetic disturbances over the next seven days.

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

The brief period of high pressure that arrived towards the end of the previous week is currently being nudged away to the east into Europe.

The coming week is dominated by very unsettled conditions with a succession of deep lows near or crossing the country and there’s even one that contains the remnants of an old hurricane.

The result is that next week will provide copious amounts of wet and windy weather, so no Tropo for us, but there may be several areas of heavy rain for a try at rain scatter on the GHz bands.

We hope you have all checked out your antennas after last week’s reminder since the winds may be quite testing for some areas.

The solar conditions have been stirred up recently by several flares so, as usual, keep an autumn watch out for auroras.

Lastly, there are plenty of meteor scatter opportunities aside from any random meteor activity. Try investigating one of the many meteor websites to see the full list of options.

For EME operators, Moon declination is at its minimum on Wednesday. So, it is a good week for checking out systems before the Sun also gets too low in the sky to make sensible Sun noise measurements over the winter. Path losses are still high but starting to fall.

If you’re fortunate to have a clear low horizon you’ll make some contacts, but with peak Moon elevation only eight degrees on Wednesday, you’ll be lucky! 144MHz sky noise in general is high to moderate for the rest of the week.

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

The news headlines:

• There is still time to book tickets for the RSGB 2024 Convention

With just two weeks until the RSGB Convention, this year’s event is the place to go if you are interested in anything and everything to do with amateur radio. There will be a host of expert speakers presenting on topics ranging from Sporadic-E and how to use AI to write amateur radio applications, to panel debates on amateur radio modes and presentations on inspiring the next generation of radio amateurs. The presentation summaries and speaker biographies are now available on the RSGB speaker page. AMSAT-UK has started to release news of its presentations too and you can see those on the RSGB’s Convention programme. There really is something for everyone. If you haven’t already bought your ticket, be sure to secure it by Monday the 7th of October when the online booking process will close. Buying tickets before the event will save you up to £5 off the usual 'on the day' ticket prices. Due to demand, the RSGB has also arranged an extra introduction to microcontroller programming workshop that will take place on the Sunday morning. There are still some tickets available for Saturday’s Gala Dinner too. To book your tickets for any part of the weekend or to find out more about the programme go to rsgb.org/convention

Jamboree on the Air, also known as JOTA, is taking place between the 18th and 20th of October. The event promotes friendship and global citizenship and is a brilliant celebration of amateur radio among the groups within the Scout Association. Some groups have already shared details of activities that will be taking place over the weekend and the RSGB plans to compile and share a list of these on its comms channels. If you are part of a Scouting group and are planning to get involved with JOTA then please get in touch via [email protected] with a summary of your station name, callsign and any other relevant information.

The RSGB has responded to a recent Ofcom Consultation which would see new users sharing spectrum within the 2.3GHz amateur band. Whilst the new devices may be limited to indoor use, the RSGB has taken the opportunity to highlight concerns regarding the weak signal 2320MHz segment. In addition, the RSGB has also indicated its wish to review the current restrictions that apply to this band that date back to 2013, when it was subject to Public Sector Spectrum Release. The response and background information can be found in the Spectrum Forum web pages at rsgb.org/spectrum-forum

The October edition of RadCom includes an article about the very first two-way radio communication between the UK and New Zealand, something that Sir Edward Appleton, radio physicist and Nobel laureate, later described as “probably the most dramatic moment in the history of the development of the short waves.” The contact was between two radio amateurs, one in Mill Hill School, London and the other on a sheep farm in New Zealand. Centenary celebrations will be taking place in New Zealand and at Mill Hill School, and special event callsigns will be active from today until late October. GB2NZ and ZM100DX will be active each day during that period and, for the week of the centenary, the near-actual callsigns used in 1924, G2SZ and ZL4AA, will be active from the 14th to the 20th of October. A commemorative certificate will be available for those who make contacts with the event stations. For more information on the Goyder-Bell award, and to find out more about the centenary celebrations, go to gb2nz.com

Lots of amateur radio stations are on the air this weekend for the Railways on the Air event. The occasion marks 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. Activity will be centred around 3.65, 7.15 and 14.25MHz.

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

Solar activity is back to moderate levels with an M3.7 solar flare detected on the 22nd of September. Newly assigned AR 3835 in the southeast quadrant is the main source and the event looks to have thrown a stream of plasma into space.

The latest model suggested a possible passage near our planet by the 25th and it looks like the prediction was correct. The Space Weather Prediction Centre issued a G1 geomagnetic storm watch and visible aurora may be likely at very high latitudes. Expect maximum useable frequencies, or MUFs for short, to decline if the Kp index is above 4 or 5.

Other than a large number of C-class solar flares in the past five days, this was the biggest eruptive event to occur.

The solar flux index had declined to 172 on Wednesday the 25th but is unlikely to decrease much further. Note that nearly all the sunspots are in the Sun’s southern hemisphere at the moment.

Meanwhile, daytime MUFs over a 3,000km path are now consistently over 28MHz under quiet geomagnetic conditions. This is good news for fans of the 10m band. Night time MUFs over 3,000km are around 14 to 16MHz, so it looks like we may soon lose the 24-hour DX openings on the 20m band, which are prevalent in the summer months.

Increasing solar proton flux at the moment means paths over the Arctic Circle may be compromised.

Daytime critical frequencies remain over 8MHz and often reach nearly 11MHz, so NVIS communications around the UK on the 40m band remain commonplace but may disappear later in the evening.

NOAA predicts that the solar flux index will increase next week but may not reach the 200s. Keep an eye on solarham.com  for daily updates.

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

The present run of unsettled weather has become firmly established and, although many parts of the country have not seen the torrential rain and flooding of last week, there will be some rain at times in most parts of the country during the first week of October.

There are a couple of brief periods in the models when a weak ridge of high pressure is due to cross southern areas, but these are not seen as great for Tropo.

The week beginning Monday the 30th of September sees at least two major lows pass close to northern Britain. One occurs as this weekend draws to a close and there may be another one later in the week. These types of changeable patterns are notorious for problems with detailed predictions beyond a few days, although the general weather type is well forecast.

Just a reminder that strong wind events at the end of a long summer can be a big shock to antennas, so now is a very good time to check that all is well in the guying department.

Having discounted Tropo as an option, the obvious choice will be rain scatter on the GHz bands, but some of these events may produce very fast-moving echo sources. So, it could be quite a challenge although last week saw plenty of good rain scatter conditions.

Meteor scatter is again largely dependent upon random meteors with just a couple of lesser showers, the Kappa Leonids and Sextantids, which see out the end of September.

The auroral situation continues to provide some excitement, and the autumn months are a good time of the year for such things.

For EME operators, Moon declination is still positive until Tuesday evening, so Moon visibility windows are shortening. Path losses are high with apogee next Wednesday the 2nd of October. Thursday the 3rd sees near-eclipse conditions when the Sun and Moon are close in the sky meaning high noise with wider beam width antennas. 144MHz sky noise is, in general, low for the rest of the week.

And that’s all from the propagation team this week

GB2RS News

Sunday the 22nd of September

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]

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.

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.

The IRTS 2m Counties Contest is also taking place on Sunday the 15th from 1300 to 1500 UTC. Using SSB and FM on the 2m band, the exchange is signal report, serial number and locator. Irish stations also give their county.

Also on Sunday the 15th, the British Amateur Radio Teledata Group Sprint PSK63 Contest runs from 1700 to 2100UTC. Using PSK63 on the 80 to 10m bands, the exchange is your serial number.

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.
