Volunteers’ Week
New edition of RadCom Basics
RSGB Emerging Technology Co-ordinating Committee
The RSGB is in the middle of celebrating Volunteers’ Week which runs from the 1st to the 7th of June. Volunteers are the lifeblood of the Society and the RSGB wants to thank everyone who gives their time and expertise to support it, and amateur radio, across such a wide range of roles. Head over to the special web page at rsgb.org/volunteers-week to hear from just some of the RSGB’s volunteers, keep an eye on the RSGB’s social media channels and look out for the special feature in the July issue of RadCom.
The new edition of RSGB’s RadCom Basics is out now. It includes articles about using FT8 and the Reverse Beacons to gauge HF propagation; repairing circuit board tracks; a compact 160m vertical; basic fault-finding; and the doublet antenna. If you’re an RSGB member go to the website at rsgb.org/radcom-basics to read this issue. If you’d like to receive an email as soon as the latest RadCom Basics is available, log in to the RSGB Membership Services portal and go to the Manage Preferences section.
The Society is looking for a volunteer to join the RSGB Emerging Technology Co-ordinating Committee, or ETCC, to act as Regional Representative for the Central England region. The function of the ETCC is to assist radio amateurs seeking an NoV to operate repeaters, gateways or beacons within the UK. The successful applicant will have broad experience of radio system engineering, analogue and digital modes, local topography and propagation theory. If you’re interested in this role, email ETCC Chair Andrew Barrett, G8DOR by the 9th of July via etcc.chairman@rsgb.org.uk
The RSGB National Radio Centre welcomes thousands of people through its doors each month and needs to expand its team of volunteers. If you are interested in becoming an NRC volunteer, you should enjoy meeting people and be prepared to work a minimum of one – preferably two – days per month. The team is particularly interested in recruiting new volunteers who are able to work at the weekend. The National Radio Centre has a fabulous set-up and full training on using the GB3RS radio station will be given. You will be joining a friendly and dedicated team. NRC volunteers also enjoy numerous benefits associated with volunteering at Bletchley Park. For more information about volunteering, please email NRC Coordinator Martyn Baker, G0GMB via nrc.support@rsgb.org.uk
Don’t forget to join the RSGB’s live Tonight@8 webinar this Monday, the 5th of June, when Mike Richards, G4WNC will be giving a live presentation on Node-RED for radio amateurs.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 1st of June 2023
We had a relatively calm period last week with the Kp index remaining below three and plenty of sunspots. Although we started the week with the Solar Flux Index in the low 150s, it quickly picked up to reach 161 by Thursday.
As a result, there was DX to be had, although most of the attention was on 6m where some outstanding multi-hop DX contacts were being made.
But back on HF and people have been chasing T31TT on the Central Kiribati Islands. Some have made it, but it's a difficult path.
Closer to home, Nobby Styles, G0VJG and Emil, DL8JJ have been active on Rockall, which is IOTA EU-189, using the callsign MM0UKI.
Rockall is an uninhabitable granite islet situated in the North Atlantic. The nearest permanently inhabited place is North Uist, an island in the Outer Hebrides of Scotland, 200 nautical miles to the east.
They have been worked from the UK mainland on 30m and 20m and heard in the east of England on 15m, possibly via Sporadic-E. They may have been a little too close to northern areas for 20m as you may have been inside their skip zone.
One of their aims is to raise as much as possible for the Royal Navy and Royal Marines Charity and ABF, The Soldiers’ Charity, so please support them if you can.
This weekend we may have unsettled geomagnetic conditions partly due to an Earth-facing coronal hole with the Kp index peaking at five.
But after the weekend things may settle with a maximum Kp index of two. The solar flux index is predicted to be around 150, declining to 130 as the week goes on, so HF conditions may be down a little on last week.
And now the VHF and up propagation news
The weather pattern seems stuck in its typical late spring/early summer state with cold north-easterly winds in eastern areas. There are good prospects for western Britain to shine but leaving eastern areas struggling.
The root cause is a large area of high pressure that is over northern Britain, and currently trying to transfer to the east, which could improve things. Either way, it does mean that Tropo was doing a lot of the propagation work last week and will do so for much of next week too.
As the high edges east, or splits into one to the west and one to the east of the UK, it could leave room for isolated thundery showers to encroach into southern and southwestern areas and give a chance of rain scatter on the GHz bands.
The main mode of interest will probably be Sporadic-E and there have been a few examples in the last week, both single-hop within Europe and multi-hop paths to the States, the Far East and Australia.
The first week of June is typically a prime period for Sporadic-E and although the jet stream position suggests mainly paths northeast to Scandinavia and Baltic regions will be best, other multi-hop options farther afield are worth exploring too.
Monitor the clusters and band maps to see where the activity is happening. If you hear this in time, you might want to check out the 24-hour UK Six Metre Group Summer Sporadic-E contest which ends at 1300UTC today, the 4th. There should be plenty of activity.
Other modes may also pop into view, such as aurora and meteor scatter, so we may be spoilt for choice.
Moon declination is negative all week and still falling until Tuesday. We are past apogee so path losses will fall as the week goes on. So we will also have short Moon windows with falling path losses until perigee late Tuesday. 144MHz sky noise is high, reaching a peak of 2700K on Monday and only going below 300K by Friday.
And that’s all from the propagation team this week.

RSGB Tonight@8 webinar
RSGB Beaconnect loop experiments
RSGB School Zone web page
On Monday the 5th of June, the RSGB’s Tonight@8 live webinar will feature Mike Richards, G4WNC who will give a presentation on Node-RED for radio amateurs. Node-RED is a visual programming language that is very powerful but surprisingly easy to use. The language has matured over recent years and has the potential to be a valuable tool for radio amateurs. In this talk, Mike will provide an introduction to Node-RED programming techniques. He will conclude with a live demonstration to show just how easy it can be to add extra facilities to your rig. Watch and ask questions live on the RSGB YouTube channel or special BATC channel. For more information see the RSGB website at rsgb.org/webinars
Three weekends have been identified for some RSGB Beaconnect loop experiments. On the 3rd and 4th of June, there will be some regional loops and nets. On the 10th and 11th of June, there will be an England-only loop and net based round the activators who have registered for Beaconnect callsigns so far, but the Society would welcome new activators in the West of England and East Anglia. Finally, on the 24th and 25th of June there will be an attempt at a multiple nations loop, although to do so the Society will need activators in Wales, Scotland and Northern Ireland. If you want to join in with these activities, register for a Beaconnect callsign via the RSGB website. Go to rsgb.org/coronation and choose the Beaconnect information page.
The RSGB’s School Zone web page brings together radio amateurs in schools and colleges. The Society wants to help people to share their experience and expertise in establishing and running a radio club for young people. The RSGB has just launched a new page as part of this section called ‘School Zone stories’ where it is highlighting some of the great amateur radio activities that are happening in these, and other, schools. If you’re a school with an amateur radio club and want to be added to the list, or a radio amateur or club that is linking with local schools, the RSGB would love to add your information and stories to School Zone. Go to rsgb.org/school-zone to find out more, or send your stories and photos to comms@rsgb.org.uk
Have you seen the RSGB Live News web page? It brings together the Society’s social media feeds, latest YouTube videos and front-page news in one place. Launched a few years ago, people found it very useful, so the RSGB is highlighting it again now for those who have become radio amateurs or returned to amateur radio more recently. Take a look at rsgb.org/live for a taster and then go to the individual comms channels to find out more.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of May 2023
The Sun currently has an equal number of spots in both its Northern and Southern hemispheres.
The Solar Flux Index was consistently in the 150 to 160s range last week, with a total of eight M-class flares. We had unsettled geomagnetic conditions on the 21st and 22nd when the Kp index hit six, but things then settled down again to a more manageable two to three.
There are times when the F-layer critical frequency is lower than the E-layer critical frequency due to Sporadic-E. This means that HF signals can’t reach the F2-layer, basically blocking off DX, but leaving Sporadic-E short skip available. So, make the most of these short-skip contacts to the continent and multi-hop Sporadic-E skips to further afield. Conditions in the F2-layer will improve in the autumn, so don’t worry!
There is still HF DX to be had, but you may have to hunt for it. Recently, Laurie, G3UML worked BD4VGZ in China on the 15m band using CW and Stuart, M1SMH worked YG2ALQ in Indonesia as well as A71UN in Qatar, on the 10m band using FT8. Meanwhile, Andy, M0NKR worked VK on the 15m band using SSB long path. Namibia, Malawi and Equatorial Guinea have all been workable from the UK using FT8 on the 10m band during late morning.
Next week NOAA predicts that the Solar Flux Index will remain in the same range. That is, in the 150 to 160s. Unsettled geomagnetic conditions are forecast from the 2nd to the 4th of June when the Kp index might reach four. Otherwise, it suggests that conditions will be mainly settled with the Kp index around two to three.
So, make the most of the elusive HF F2-layer openings and the various opportunities available during this peak time for Sporadic-E propagation.
And now the VHF and up propagation news
The broad scale pattern is still dominated by a large area of high pressure over the country with its centre mostly to the northwest of the British Isles.
The whole period through to the end of the coming week should offer some good tropo prospects, so why not try using CW or SSB to add some extra squares to your log? Under lift conditions, even a halo antenna can be surprisingly effective.
The weather variety will remain until the end of next week when low pressure over France tries to push some thundery showers northwards into southern Britain after midweek, and perhaps then northwards as far as western Scotland. This brings a chance of rain scatter on the GHz bands.
There is, as usual, always a chance of aurora and meteor scatter to bring additional options, but the main mode of interest this week will be Sporadic-E as we head into the peak of the season.
With tropo also in play, it’s worth a quick note for those not used to working Sporadic-E; Tropo tends to be long-lasting and usually better on the higher bands. That is to say, the 70cm band is often better than the 2m band whereas Sporadic-E is usually brief and better at lower frequency bands. So, the 10m band is better than the 6m band.
This time of the year it can reach up to 2m on rare occasions. If you do nothing else, simply check the bands and clusters at the end of the afternoon to maximise your Sporadic-E chances.
Moon declination is positive but falling this weekend, going negative on Tuesday. We are past apogee so path losses will fall as the week goes on. We’ll see shortening Moon windows with falling path losses. 144MHz sky noise is low all week.
And that’s all from the propagation team this week.

Youngsters on the Air camp
RSGB Board appointment
RadCom Basics Editor
The RSGB has announced the team of young members who will be representing the Society and the UK at this summer’s Youngsters on the Air camp. The event, hosted by the Hungarian Radio Amateur Society MRASZ, will take place in Gyor, Hungary between the 5th and the 12th of August. The team is made up of team leader Alexander, 2E0FMZ and members Henry-James, M7HJR; Hannah, M7YYQ and Jake, M7JNS. You can read more about the camp and the team on the RSGB website at rsgb.org/yota-hungary
The RSGB Board has decided to co-opt Ian Shepherd, G4EVK as a Board Director until the 2024 AGM. Please see the Board’s explanation of this appointment on the Society’s website at thersgb.org/go/boardcoopt
The RSGB is sad to report that RadCom Basics Editor Lee Aldridge, G4EJB wishes to retire later this year. The RSGB thanks Lee for all his hard work and effort in the making of RadCom Basics. If you are interested in taking on the role of RadCom Basics Editor, please email radcom@rsgb.org.uk
Last year, the RSGB was approached by the BBC to find experts to contribute to its planned series ‘The Secret Genius of Modern Life’. For episode one, which takes a look at the bank card, Neil Smith, G4DBN re-created the Great Seal Bug – a wooden seal, gifted to the US embassy in Moscow in 1945, and which contained a covert listening device. The technology developed for the bug was an early example of RFID, which is what allows contactless card payments to work. Neil has now released a series of fascinating videos on his YouTube channel which explain the history of the Bug as well as the mechanical design and machining needed to re-create it. You can find the videos in Neil’s playlist on ‘Machining and Microwaves’ and you can watch the original BBC Two programme on BBC Sounds – this episode is available for a further seven months.
The RSGB National Radio Centre welcomes thousands of people through its doors each month and needs to expand its team of volunteers. If you are interested in becoming an NRC volunteer, you should enjoy meeting people and be prepared to work a minimum of one – preferably two – days per month. The team is particularly interested in recruiting new volunteers who are able to work at the weekend. The National Radio Centre has a fabulous set-up and full training on using the GB3RS radio station will be given. You will be joining a friendly and dedicated team. NRC volunteers also enjoy numerous benefits associated with volunteering at Bletchley Park. For more information about volunteering, please email NRC Coordinator Martyn Baker, G0GMB via nrc.support@rsgb.org.uk
Interest in QRP activity is as strong as ever in the worldwide amateur radio community.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 18th of May 2023
After last week’s NOAA prediction that we would have settled geomagnetic conditions all week, it seems they were right! The Kp index never got above three – a miracle given the recent disruption due to coronal mass ejections and coronal holes.
The proton flux from the Sun has declined as well. However, an M9 solar flare on Tuesday from active region 3310, and numerous C-class flares, maybe a precursor to more flare activity next week.
With a solar flux index in the 130s and 140s, HF conditions have been quite good. Daytime maximum usable frequencies over a 3,000km path have usually exceeded 21MHz, with 24MHz seeing occasional F2-layer openings, as well as sporadic E propagation.
At the moment, the 10m band is mainly open to Sporadic-E propagation with more DX paths now locked out until the Autumn. This is in line with predictions, as the ionosphere changes in the Northern Hemisphere summer with a change to more diatomic elements, which are harder to ionise.
So, will our luck hold out next week?
The Space Weather Prediction Centre forecasts that the Solar Flux Index, or SFI, will decline slightly to the 120s and this weekend should be geomagnetically settled. However, it is predicting that the Kp index will rise again from the 23rd of May. It suggests that the Kp index may hit four or even five for a few days before becoming more settled again from the 30th.
The US Air Force disagrees and thinks the SFI will be higher, perhaps hitting 145 and even 155 by the 28th. It agrees that we are in for more unsettled geomagnetic conditions from the 24th to the 28th, possibly due to a coronal hole rotating into an Earth-facing position.
So, expect MUFs to decline if the Kp index goes up, with poor overall HF conditions.
It is certainly looking like this weekend may see the best conditions for HF, so we suggest you get your DXing in right now, with 14 to 21MHz offering the best prospects.
And now the VHF and up propagation news
The upcoming weather week will be predominantly high-pressure driven, with an elongated region of high pressure from the Azores to Scandinavia.
However, there is still scope for a few blemishes and as we end the current week it comes as isolated showers, especially in the south and weakening fronts over north-western Britain. Early next week, a brief period with low pressure over the near continent will threaten some heavier rain for south-eastern areas.
Concentrating on the high-pressure part of the story, this means Tropo is a strong player and will hopefully be in attendance for the 144MHz May Contest and 144MHz Backpackers Contest this weekend.
Remember that, in the summer months, Tropo becomes much weaker over the land during the stronger heating of the daytime sunshine but can become quite widespread overnight and around coasts.
The rainfall component can lead to good rain scatter options, especially as the summer usually produces more intense rainfall, so performs better as a scatterer on the GHz bands.
The other primary propagation mode is going to be Sporadic-E as we move into the peak summer months. Follow the position of jet streams on the upper air charts, shown on propquest.co.uk and described in a daily blog.
Don’t forget there are always modes like aurora and meteor scatter, which can add to the excitement, but will need to be checked each day.
Moon declination is at its highest this weekend for the Dubus EME 10GHz and up SSB/CW contest, peaking on Monday. With apogee next Friday, path losses will continue to increase.
144MHz sky noise is moderate early next week becoming low by 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 11th of May 2023
Our topsy-turvy world of HF propagation continued last week with geomagnetic storms, solar flares, coronal mass ejections, proton events and more.
The good news is that the solar flux index was at 170 by Thursday, but the bad news was that we had two episodes where the Kp index hit five and there were at least five M-class flares.
At least one of these flares was responsible for a coronal mass ejection, or CME, which swept past the Earth on the 10th of May with a solar wind speed close to 700km/s. Although it was fierce, it was relatively short-lived and the Kp index was back to three on Thursday the 11th.
The CME caused the maximum usable frequency over 3,000km to decline to around 21MHz at times on Wednesday, but by Thursday morning it was back up to nearly 28MHz.
The high proton flux also caused problems on the 10th of May. The protons, mainly from CMEs, move down the Earth’s magnetic field lines into the polar regions and cause massive ionisation of the polar D region leading to increased, or total, absorption of HF waves.
This effect may last for as long as ten days and is called a Polar Cap Absorption event, or PCA. This affects signals going over the poles, such as the UK to the west coast of Canada and the USA, or to Japan and the far east.
Meanwhile, we are now underway with the Sporadic-E season, so make the most of the short skip and potential multi-hop Sporadic-E DX on 14 to 28MHz.
Next week, the Space Weather Prediction Centre has the Solar Flux Index declining slightly into the 150s. This is still more than enough to maintain DX on 21MHz and higher at times. It also predicts that the Kp index will be no higher than a stable 2 all week.
However, that is hard to believe, with the level of solar activity at the moment, and we could reasonably expect the Earth to be hit with a CME or two at some stage. This could see the Kp index rising with the potential of reduced MUFs at times.
And now the VHF and up propagation news
After a very unsettled end to the week, with lots of rain scatter reported, it will soon quieten down as a ridge of high pressure builds across the country to give some limited Tropo opportunities for the start of the weekend.
This will not last long and by this evening, it will be heading back to unsettled with low pressure, heavy rain and rain scatter. This unsettled theme will last through the first half of the new week together with strong north-easterly winds. Thereafter, high pressure will build again for the second half of the week, providing further Tropo options.
Keep a watch for Aurora, especially in view of the current unsettled solar state. CMEs will mean a very unsteady Kp index and anything higher than five should get your attention for auroral propagation. No significant meteor showers are expected this week, but QSOs using random meteors are always a possibility in the dawn hours.
Likely to be of interest in the summer months ahead, there have already been Sporadic-E openings on 6m CW and FT8 into Europe. Early evening trans-equatorial 6m FT8 QSOs to South America, the Indian Ocean and the South Atlantic were reported from the UK last week.
Check Propquest.co.uk for daily blogs and make use of the DX cluster and map plots to see where the actual centres of activity are located.
Timings can be a bit random early in the season, but there tend to be two ‘openings’ per day – one in the morning and a second during the late afternoon or early evening.
Moon declination is rising, going positive again next Tuesday. But last Thursday’s perigee means path losses are on the increase. 144MHz sky noise is low until Friday when the Sun and Moon are close in the sky for the whole Moon window. Things return to normal early on Saturday and sky noise is moderate.
And that’s all from the propagation team this week.

Matthew, M0MZB from Calder Bridge in Cumbria, has become a SOTA Mountain Goat in impressive style. He reached the 1,000 activation point threshold with an overnight activation of High Stile G/LD-012 in the English Lake District. Matthew set up overnight camp on the summit of the long ridge above the western shore of Lake Buttermere. He operated both on VHF and HF and made a summit-to-summit contact with Alex Hill, G7KSE who was on the Dent summit, G/LD-045. Since getting involved in Summits on the Air, Matthew's expeditions have left many radio amateurs in awe. He has conducted many multi-summit expeditions without motorised transport, traversing between summits entirely on foot or by bicycle. Upon reaching the coveted Mountain Goat status, Matthew commented: "SOTA has given me new ideas for my little expeditions and has put me in touch with lots of new friends. The challenge of Mountain Goat has included many facets, from learning CW to antenna building, from battery technology to fishing poles." For more information about Summits on the Air visit www.sota.org.uk

Next week will see the Sun presenting with four large sunspots groups that are rotating to be Earth-facing, so look out for trouble. Just as the UK weather takes a turn for the worse, we expect the space weather to be unpredictable too!
Active regions 3293, 3294, 3296 and 3297 look dark and are looming large on the Sun’s face. Region 3293 emitted an M7.2 class solar flare on the 3rd of May, which the Space Weather Prediction Centre reported was likely due to an intensification of the magnetic field within the spot group.
The flare caused some degradation of the ionosphere, but nothing too serious. However, the Space Weather Prediction Centre now predicts that further flares could follow, perhaps even a strong X-class flare, which could have more serious effects.
If an X-class flare occurs in daylight over the UK, we can expect the HF bands to be affected in what is known as a sudden ionospheric disturbance or Dellinger fadeout. This could see the lower HF bands shut down due to extreme ionisation in the D-layer, only for the band to return to normal over a period of minutes to an hour.
More worrying is the fact that the flare could spark a coronal mass ejection, or CME, which, if Earth-directed, could cause the Kp index to rise, MUFs to drop and bring auroral activity a few days after the CME. So, keep an eye on solarham.net for updates.
Meanwhile, the solar flux index, or SFI, remains in the 150s and this looks set to continue. The US Air Force predicts the SFI will start the week at 152, then dip slightly, before reaching 170 by the 12th of May.
It also predicts that geomagnetic conditions will be settled once we get past this weekend, which could see the Kp index rise to four. These unsettled conditions may be due to a coronal hole, which became Earth-facing on Thursday.
Propagation-wise, F2-layer maximum usable frequencies over a 3,000km path has struggled to exceed 21 to 24MHz during daylight hours as we head towards summer.
The season is characterised as having lower MUFs during the day, but these tend to be maintained into the hours of darkness. Meanwhile, Sporadic-E might spring some surprises for paths over 800 to 2,200km on 14 to 28MHz, with very strong signals and rapid fading.
And now the VHF and up propagation news
The weather pattern is taking a change to unsettled as we move through this first May weekend, with low pressure dominating the charts and throwing active weather fronts across the country.
This will produce some quite heavy rain at times and perhaps even some thundery activity. This bodes well for rain scatter on the GHz bands.
This pattern extends well into next week, eventually changing from a south-westerly to a north-westerly followed by a building ridge of high pressure to bring a temporary hint of Tropo to end the week.
This opens the more exotic modes to consider, such as meteor scatter and possible aurora, but these are very much outliers to the main interest at this time of year, which is Sporadic-E. The season has nominally started, and daily blogs are being added to the website Propquest.co.uk, which describe the more likely regions to find Sporadic-E opportunities.
This unsettled weather pattern brings a useful bonus in that it is often associated with jet stream activity. The whole period offers several jet streams across Europe, a positive for the start of the new Sporadic-E season since jet streams are often associated with the location of Sporadic-E activity.
Moon declination is low and falling, reaching minimum next Tuesday. EME Moon windows will be short. Perigee is Thursday, so when you do have a view of the Moon, path losses will be low. 144MHz sky noise is high, reaching over 3200K late on Monday.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 27th of April 2023
What a busy week we’ve just had! It started with a massive G4 geomagnetic storm that saw the Kp index rise to eight with aurora visible as far south as Cornwall and the Channel Islands. This was due to a coronal mass ejection from a filament eruption on the 21st of April.
The 6m band came to life during the early stage of the storm with distorted aurora signals throughout the SSB and CW sections. However, the HF bands suffered, with MUFs down on the morning of the 24th. The 25th wasn’t much better with MUFs over a 3,000km path barely reaching 18MHz all day.
By Thursday the 27th the Kp index was still at four.
However, there were surprises to be had. Phil, GU0SUP reported that at 1300UTC on Monday the 24th, he was amazed to work Yuris, VU7W on the Lakshadweep Islands on 10m FT8, with good signals both ways. He says the Kp index was at six and the regular FT8 frequencies on both the 10m and 12m bands were pretty much dead.
On Wednesday the 26th, Peter, G8BCG reported, on the CDXC reflector, that 15m FT8 was open all night via the long path to Australia, New Zealand and the Pacific.
It is always worth checking the HF bands during a major geomagnetic storm as there may be surprises to be had.
Next week the Space Weather Prediction Centre thinks that the Solar Flux Index will remain in the range of 135 to 140. The Kp index may remain around two to three. However, as last week showed, we are now really into uncharted territory, in terms of solar activity, with daily multiple solar flares and associated coronal mass ejections.
So, don’t be surprised if we have another major geomagnetic disturbance with an elevated Kp index.
And now the VHF and up propagation news
The weather pattern in late spring often settles into a period of south-easterly winds from a rapidly-warming Europe and the signs are there for just such a flow during the coming week.
The sequence starts with unsettled weather and possible rain scatter from heavy April showers into the first weekend but, thereafter, a weak ridge of high pressure will move in to bring a chance of Tropo for next week. Paths along the east coast should do well, especially if there are large areas of sea fog and misty low clouds over the North Sea.
At longer timescales, the period towards the following weekend will see eyes looking towards a low to the southwest of the British Isles that could push some thundery rain into southern areas by the end of the week and again bring a chance of rain scatter on the GHz bands.
The jet stream pattern remains complex with several potentially useful flows that might be instrumental in prompting some early-season Sporadic-E propagation.
Last week, the Portuguese CS5BALG beacon on 50.036MHz in IM67, and CS5BLA on 50.0760MHz, made a welcome return. Sporadic-E can be very fleeting early in the season, but keeping a regular check on the usual beacons should give you a chance of being there at the right time.
The daily Sporadic-E blogs start on the 1st of May on www.propquest.co.uk and should give some clues as to any early-season options.
Lastly, the Sun has kept everyone busy recently with visible and radio auroras, so check the Kp index for aurora potential. And we are in a period when increasing meteor input is starting to help provide better meteor scatter prospects, as well as fuel for Sporadic-E. The Eta Aquariids has a broad peak zenithal hourly rate of around 50 next weekend on the 6th of May.
Moon declination is high and falling, meaning shortening EME Moon windows and peak elevations. We passed apogee on Friday so path losses will fall throughout the week. 144MHz sky noise is low to moderate.
And that’s all from the propagation team this week.

The RSGB is delighted that Ofcom has confirmed that the callsign GB23C can be used for the RSGB’s Coronation Special Special Event Station. Cray Valley Radio Society members led by Bob, M0MCV and Dave, G4BUO are organising the flagship amateur radio station that will use this callsign from the 3rd to the 8th of May. The Special Special Event Station will be on the grounds of the Old Royal Naval College, along the riverside in Greenwich. From the 10th of May onwards, the callsign will be available for individuals and clubs to use until the end of June 2023, and further details about this will be announced shortly. Ofcom has also kindly agreed to a block of 676 Special Special Event Station callsigns for the RSGB’s Be a Connect activity for the Coronation. These are GB23BAA to BZZ, which will be available throughout May and June. More details on how to obtain one of these will be given next week, but meanwhile, you may wish to find a beacon site you could activate one or more times for this event. Finally, if you are planning outreach activities with local clubs and groups, take a look at the paper circuit template the RSGB has just shared on its website – go to rsgb.org/coronation and choose the coronation activity ideas tab in the right-hand menu.
The RSGB’s AGM was held online last Saturday, the 15th of April. If you missed the live event, you can see the results of the elections and follow links to the trophy awards and the construction competition winners on the RSGB website via rsgb.org/agm. You can also catch up on the full live stream or watch individual sections on the Society’s YouTube channel. The RSGB has released separate videos of the outgoing President’s review of 2022, its new short Convention promo, and the interesting presentation about preparing the GB2RS propagation reports by the RSGB Propagation Studies Committee Chair, Steve Nichols, G0KYA. You can see them all in the RSGB 2023 AGM playlist on YouTube via youtube.com/theRSGB
Following the RSGB AGM on Saturday the 15th of April, a brief Board meeting was held to consider necessary appointments. The Board was aware that Stewart Bryant, G3YSX, who had been in a dual role since the recent resignation of Richard Horton, G4AOJ, had expressed a willingness to continue as Chair if required. It was agreed that Stewart should be co-opted to the Board under the terms of Article 37 and was asked to join the meeting. Stewart was then elected unanimously to serve as RSGB Board Chair until the 2024 AGM.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 20th of April 2023
We had a surge in sunspot activity over the last week, pushing the solar flux index up to a maximum of 178, although it subsequently declined to 147.
Solar flare activity was quite subdued after a frantic period from the 13th to the 15th that saw 40 C-class flares and two M-class flares erupt.
This activity was mostly centred around active region 3282 in the northwest quadrant.
Geomagnetic conditions were unsettled for a time around the 18th and 19th with the Kp index hitting a maximum of 4.3. This appears to have been due to enhanced activity from a coronal mass ejection and continuing coronal hole activity that saw the solar wind speed hit more than 600km/s and the Bz swing south.
The critical frequency was down below 7MHz on the morning of Wednesday the 19th, which impacted near-vertical incidence skywave signals around the UK.
This impacted maximum useable frequencies, which struggled to exceed 21MHz over a 3,000km path on Wednesday, although by Thursday they were back over 28MHz again. A critical frequency of more than 10MHz meant the 40m band was once again suitable for close-in contacts around the UK.
There were many reports of DX being worked later on during the week, with Australia and New Zealand topping the bill on 18MHz and 28MHz.
Next week NOAA has put a more positive spin on sunspot activity. The Solar Flux Index is predicted to be in the range of 168 to 172 for the first half of the week, falling to around 160 in the second half.
But we could be in for a bumpy ride geomagnetically, with the Kp index predicted to hit five on Wednesday the 26th of April through to Monday the 1st of May. This may be due to the return of solar phenomena that occurred 27 days ago and saw the Kp index get up to 4.67.
Meanwhile, a very large solar coronal hole, albeit positioned very south on the Sun’s surface, and a much smaller one on its equator, threaten HF conditions this weekend.
Keep an eye on the real-time solar wind from the ACE spacecraft for signs of a rise in speed and a southward-pointing Bz interplanetary magnetic field on solarham.net. This could push to Kp index higher, perhaps to four.
And now the VHF and up propagation news
The Sporadic-E season is nearly upon us. Remember it will usually activate on 28MHz and then higher bands will follow if the event intensifies. There have been some 50MHz FT8 paths flagged up on DXmaps.com, although some may have been tropo.
The recent large high pressure centred over Scandinavia has been a bit subdued as regards Tropo. Much of the time, the air nearer the surface has been fairly dry with little sign of banks of sea fog over the North Sea, which would suggest better ducting potential.
We are now entering a phase with low pressure on the charts, initially over the south of Britain, but edging north for a time before drifting out across the North Sea.
This could produce some rain scatter on the GHz bands, especially should any heavy April showers develop.
Early next week a ridge will edge south across the UK in a colder northerly weather pattern, so although high-pressure returns, it may not be especially good for tropo.
The third changeover comes after midweek when a milder south-westerly returns with active fronts bringing rain and unsettled weather, especially to the north and west. This could mean further opportunities for rain scatter on the GHz bands and perhaps a hint of tropo in the Southeast towards the continent.
Aurora and meteor scatter are well worth considering, and the Lyrids shower peaks on Sunday the 23rd. The message is to monitor meteor scatter frequencies and the clusters for signs of activity and, of course, try putting out a CQ call!
Moon declination is positive and rising, meaning increasing Moon time and increasing peak elevation until peak declination on Tuesday. Moon apogee is next Friday so path losses increase all week.
144MHz sky noise is moderate to low.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 13th of April 2023
A news item this week suggested that the peak of solar cycle 25 could be coming earlier than expected. According to a paper in Frontiers in Astronomy and Space Sciences, by solar scientist Dr Scott Macintosh, the solar maximum may now be coming between late 2023 and mid-2024. So, make the most of the higher Solar Flux Index now!
Solar activity picked up nicely over the past week. The solar flux index rose to 154 and there were eight active regions on the Sun’s visible face by Thursday the 13th. Nevertheless, daytime maximum usable frequencies, or MUFs, remain down a little, which has probably more to do with seasonal ionospheric changes than reduced sunspot activity.
As we head towards Summer we will see the daytime F2-layer MUF decline further before it picks up again in the Autumn.
We also saw some M- and C-class solar flare action this week, but this was not really enough to cause serious problems to the ionosphere.
Next week NOAA predicts the Solar Flux Index will continue to increase, perhaps peaking at 160 around the 16th to 18th of April. Unsettled geomagnetic conditions are forecast for the 18th, perhaps with the Kp index rising to four.
The forecast for International Marconi Day on the 22nd of April is for a Solar Flux Index of 155 and a declining Kp index of three, which bodes quite well for the event.
In all, the Solar Flux Index is expected to be in the range of 140 to 160 for the rest of the month.
And now the VHF and up propagation news
A big contrast is coming next week, so it’s time to dust off the VHF gear again!
The unsettled weather of this last week will make a complete swap over to more settled high-pressure systems next week.
Initially, on Sunday this will appear as a ridge over the North Sea from a large high over Scandinavia. This will then gradually extend across the country and will eventually be joined by a second high west of Britain.
The end result will be enhanced Tropo prospects in the coming week and potentially good conditions for the 23cm UK Activity Contest on Tuesday the 18th and the 4m UK Activity on Thursday the 20th.
Those who enjoy rain scatter propagation in this current showery weather will have to look for other modes by Sunday, once the high pressure builds.
As we are coming out of the Winter lull in meteor shower activity, with the medium-rate Lyrids peaking on the 23rd of April at 0100UTC with a Zenithal Hourly Rate, or ZHR, in the 20s, it's well worth a look for meteor scatter contacts.
The end of April normally prompts a return of isolated Sporadic-E reports on the 10m band and perhaps even with data modes on 6m. The upper troposphere jet stream charts suggest it’s got some potential, especially between Mediterranean countries although not quite so positive for paths nearer to home.
The solar conditions may continue to offer a random chance of some aurora, so remember to keep an eye on the Kp index if it goes above five.
For EME operators, the Moon perigee is on Sunday so path losses are at their lowest. Moon declination is rising, going positive on Tuesday meaning increasing Moon time and increasing peak elevation passes.
144MHz sky noise is low, but the Moon is close to the Sun on Wednesday and Thursday meaning high Sun noise for those days.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 6th of April 2023
Solar activity declined this past week with the Sun looking distinctly spotless, other than active region 3270.
In fact, this has even prompted some amateurs to question whether we are now past solar maximum for this cycle. Rest assured, we shouldn’t be, as it is pretty common for cycles to ebb and flow as they develop.
Having said that, half of the Sun’s face is currently spotless, and NOAA predicts that the solar flux index will be in the range of 110 to 130 next week.
Geomagnetically, things have been reasonably settled with the Kp index reaching a maximum of 4.67 over the past seven days. NOAA predicts that it could rise to four on the 10th and 11th of April but will otherwise stay pretty much as it is in the range of two to three. This may be due to a coronal hole that is currently making its way across the Sun’s face in a near-equatorial position.
However, we may not have seen the last of the activity from active region 3270, which has increased in both size and magnetic complexity during the past 48 hours and could soon produce a moderate M-Flare. But, if you are reading or hearing this on Sunday, the region will be moving out of sight and is therefore no longer a threat.
Daytime F2 critical frequencies at midday remain around 9 to 10MHz giving a maximum useable frequency, over a 3,000km path, of just over 28MHz.
If 10m isn’t doing it for you we suggest moving down to 12 or 15m. Night-time F-layer critical frequencies are around 3 to 5MHz meaning MUFs over 3,000km are below 14MHz, leaving 3.5, 7 and 10MHz as the best bets for nocturnal DX.
And now the VHF and up propagation news
The current spell of high-pressure weather with enhanced Tropo, which turned up in time for the 2m UK Activity Contest on the 4th of April, is looking a bit vulnerable as active weather fronts come in from the Atlantic.
We are likely to have a brief change to unsettled conditions weather-wise before the start of the Easter weekend and again see some rain scatter opportunities on the GHz bands.
Scandinavian highs are often long-lasting at this time of the year and this high will regain control by Good Friday and should dominate over the UK during the Easter weekend to give some useful tropo possibilities again.
However, quite early next week a new powerful Atlantic jet stream pushes into northern France and will bring a return of unsettled weather and perhaps more rain scatter.
The Sporadic-E season is approaching and the higher HF bands like 10m can show good examples of Es, even during the second half of April, so a good chance to get into the habit of checking your ‘go to’ list of 10m beacons as recently updated by Steve, G0KYA, on the propagation section of the RSGB website.
The other defaults of auroral propagation have had a good run recently and random meteor scatter could also prove fruitful as we are soon ending the early year ‘drought’ of meteor showers with the arrival of the Lyrids later this month.
For EME operators, Moon declination is negative and falling, reaching its minimum next Wednesday. Moon time will be limited to low-elevation passes, but with low path losses as we approach perigee on the 16th.
144MHz sky noise is increasing to a high of more than 2,000 Kelvin next Wednesday before falling back to the mid-200s the following Sunday.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 30th of March 2023
We were right in our prediction about the effects of the large solar coronal hole last week, which saw the Kp index peak at 7.67 with widespread aurora visible from the UK, even in the south.
This was probably the most significant geomagnetic event we have had so far in this solar cycle.
Last week saw another X1.2 solar flare erupt on the Sun. This one erupted from active region 3256 on the 29th of March at 0233UTC. It didn’t impact the ionosphere over the UK, but a fadeout was observed over the Pacific region.
This was the seventh major solar flare since 2023 began. The Sun has now matched 2022’s total –and it's only March!
The associated CME off the southwestern limb of the Sun was modelled and determined to be well ahead of the Earth’s orbit. This means that we are unlikely to see the Kp index rise as a result of this event.
This region also produced an M1.2 flare that peaked around 1407UTC and an M1.1 flare at 2347UTC. The earlier flare didn’t seem to affect the ionosphere too much according to the ionosonde data.
A minor solar wind stream is heading for Earth and is due on Saturday the 1st of April. The material is flowing from a relatively small coronal hole in the Sun's atmosphere, but it is on the equator and very Earth-centric. Expect Arctic auroras and an elevated Kp index when the solar wind arrives this weekend.
The SFI remained fairly static, around 160, earlier in the week but then declined to 148 on Thursday the 30th. NOAA predicts that this decline will continue next week, perhaps down to the low 130s. Once the weekend’s geomagnetic conditions recover, NOAA predicts that the rest of the week should be quite settled.
This is good news for HF propagation, although do continue to watch out for solar flares and CME activity which could affect conditions and MUFs.
And now the VHF and up propagation news
We have three phases of weather to consider over the next week. Forecasts predicted an unsettled weekend with rain and strong winds, so should have provided a focus for rain scatter on the GHz bands.
The weekend ends with developing high pressure which lasts into early next week. There is good potential for some tropo from Sunday afternoon until about Tuesday lunchtime.
At the time of writing, the best paths are likely to be from southern England into the near continent, also via Biscay to northern Spain and across the southern North Sea to Denmark.
The third phase occurs when the high moves to the south to allow fronts to move in from the Atlantic across northern Britain, but possibly still leaving tropo into France and across Biscay. Later in the week, the high pressure may head back north again to reintroduce tropo to northern areas.
The Sporadic-E season is fast approaching, typically from mid-April on 10m. If anything does happen before then, check the propquest.co.uk website for the Es blog tab, which shows the current day’s jet streams and will maybe provide a clue for which direction to beam.
Remember to look for aurora if the Kp index reaches five or more and, of course, meteor scatter around dawn for those random meteor QSOs.
For EME operators, Moon declination is positive until Wednesday, so still plenty of Moon time to get some QSOs in. Perigee was last Thursday, so path losses are now falling. 144MHz sky noise is low, rising slowly throughout the week.
And that’s all from the propagation team this week.
