RSGB collaborates on a special contact with the International Space Station
The RSGB’s Tonight@8 webinar autumn programme starts tomorrow, the 2nd
The RSGB is getting ready for National Coding Week
We are delighted to announce that the Radio Society of Great Britain and ARISS, in conjunction with Girlguiding Surrey West and Brooklands Museum including the Innovation Academy, have been collaborating on a special event due to take place on Saturday the 5th of October. Girlguiding President, Her Royal Highness The Duchess of Edinburgh will attend a planned contact with the International Space Station as part of a visit to promote the engagement and involvement of girls and young women in science, technology, engineering and maths. Further details of the contact and the event will be announced in late September.
The RSGB’s autumn Tonight@8 programme starts this Monday, the 2nd of September. Brian Coleman, G4NNS will give an update on the Meteor Beacon Project which is a cooperation between the worlds of amateur radio and astronomy. The first phase of this project was completed in May 2022 when the UK meteor beacon GB3MBA went on the air from the Sherwood Observatory of the Mansfield and Sutton Astronomical Society. It enabled studies of meteor events over the UK using simple equipment and made possible a range of STEM projects featuring radio and astronomy. The second phase of the project, which Brian will describe in the presentation, is to develop a network of receivers streaming their data via a central server for detailed studies of individual meteor events. You can watch and ask questions live on the RSGB YouTube channel or a special BATC channel. To find out more go to the RSGB website at rsgb.org/webinars
The RSGB is getting ready for National Coding Week which begins on the 16th of September.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 29th of August 2024
We had a good week for HF propagation, at least until we had a Kp index of 5.67 on Wednesday the 28th. This was caused by the Bz component of the interplanetary magnetic field moving into a south-pointing position.
Luckily, it didn’t last long and geomagnetic conditions were back to normal by Thursday.
The solar flux index remains above 200 with no sign of it dropping. But solar flare activity has not diminished either with 16 M-class flares over the past seven days and more than 60 C-class events. There remains a 55% chance of a further M-class flare and a 10% chance of an X-class event.
Tuesday the 27th saw some good activity on the upper HF bands with the 10m band opening up at times. VK has been heard on 28MHz in the mornings, which bodes well for the coming months.
The top DX choice this week has been CY9C on Saint Paul Island near Newfoundland. The team is active on all bands until the 5th of September using CW, SSB, FT8, Super Fox and RTTY. VOACAP Online shows that the 20 and 17m bands offer the best chance for a contact and are open from 0900 to 2000 UTC. The 30m band is another strong contender from 2000 to 1000 UTC.
Next week, NOAA predicts that the solar flux index will start at around 250 but could end the week at 275. As always, it estimates the Kp index will be at 2 all week, but this will depend upon coronal mass ejections, so keep an eye on solarham.com for daily updates.
If a solar flare and associated coronal mass ejections do occur, expect the Kp index to rise after about 48 hours, with a lowering of the maximum useable frequency.
And now the VHF and up propagation news from G3YLA and G4BAO
The autumn season usually brings thoughts of Tropo since areas of high pressure can often be a feature of this time of year. Most models predict that there will be high pressure moving in to offer Tropo conditions today, the 1st.
Thereafter, the models differ, and some bring low pressure over the country for much of the coming week, while others maintain a high-pressure story and the continuation of Tropo.
This is potentially useful for the 144MHz UK Activity Contest on Tuesday and Wednesday and, if it lasts, the 144MHz Trophy Contest next weekend along with the Backpackers contest on Sunday the 8th.
With the uncertain feel of the forecast at the moment, we may find rain scatter is the main option on the GHz bands.
Meteor scatter is again reduced to non-shower random events with just a minor shower, the Aurigids, peaking on the 31st of August. This shower has produced brief unexpected outbursts with a zenithal hourly rate of around 30 to 50 per hour in 1935, 1986, 1994 and 2019.
Random meteor flux is at its annual maximum in September with relatively good rates, especially during morning hours. Pre-dawn is the best time to try.
The solar conditions continue to provide chance auroras. Keep one eye on the Kp index and lock the frequency of some northern European beacons into your rig’s memory.
Lastly, it's the nominal end of the 2024 summer Sporadic-E season and the daily blogs on Propquest have finished. However, some years can produce surprise Sporadic-E events during the first week of September.
Moon declination starts the weekend still high but falling, going negative again on Thursday the 5th. So, Moon visibility windows will also fall, as will the peak Moon elevation.
Moon apogee is also next Thursday so path losses are still increasing. 144MHz sky noise is low until Monday but, shortly after moonrise that day, the Sun and the Moon become close in the sky and continue to be until after moonset on Tuesday.
This means sky noise will be very high, especially at VHF, due to wide antenna beamwidths.
And that’s all from the propagation team this week.

The RSGB 2024 Convention will feature a microcontroller programming workshop
You can take the RSGB Morse competency test at National Hamfest this year
RSGB Board Director Peter Bowyer, G4MJS to take on Board Liaison roles for contesting and trophies
At this year’s RSGB Convention, there will be a workshop to introduce attendees to microcontroller programming through a short presentation followed by practical exercises. The Society aims to widen the programming skills in the amateur radio community and introduce individuals to radio-related usage of Micro Controller Units, or MCUs. If you attend the workshop, you will receive a genuine Arduino board, a set of DuPont wires, a breadboard and two specific devices which you will be able to take away with you at the end of the workshop. The exercises will take you through using the Arduino IDE, basic programming and interfacing to the provided devices. You need to pre-register as spaces are limited to just 20 people. The workshop and hardware are free, but in return for the £10 booking fee, you will receive a copy of the book “Microcontroller Know How” by Mark Jones, G0MGX. You must be a ticket holder for the Convention to be able to take part. To find out more and to book your place, go to the RSGB website at rsgb.org/convention and choose the workshops and forums tab on the right-hand menu.
If you’re going to the National Hamfest on the 27th and 28th of September, why not try the RSGB Morse competency test? You don’t have to book in advance, just visit the RSGB village area. You can be tested at 10, 12, 15, 20, 25 or 30 words per minute so you don’t have to be a CW expert. If you pass the test, you’ll either receive a certificate on the day or it will be sent to you electronically shortly after. Eric Arkinstall, M0KZB is the RSGB Morse Competency Project Lead and he will guide you through the test process. If you don’t want to do the test you can still drop in to try Morse for the first time or pick up some hints and tips. It will be a busy event so whilst there will be headphones available, you’re welcome to bring your own if you prefer. Eric looks forward to seeing you at the event! If you have any questions, please contact Eric via morse.tests@rsgb.org.uk

The episode includes the first of a two-part feature on operating via the QO-100 geostationary satellite with a look at the hardware and software needed to achieve your first QSO at home or out mobile. Bob, G0FGX reviews the FTM-500D which is the latest mobile transceiver from Yaesu and demonstrates the many advanced features of this versatile FM and digital rig. There is a visit to Sidmouth Amateur Radio Society which secured a derelict former sports social club from the local council and turned it into a community hub and the club’s new QTH. Watch this interesting episode and don’t miss out on the TX Factor free-to-enter draw with a chance to win three RSGB publications. You can see this and previous episodes on txfactor.co.uk
The four-year planning rule has offered a degree of protection for antennas and masts that have been erected without planning permission. Under this rule any installations which had been installed and unchanged for four years or more were protected against planning enforcement action. However, as of the 25th of April 2024, this rule ceased to exist in its current form in England under changes introduced under the Levelling-up and Regeneration Act 2023. The rule has been replaced by a more stringent ten-year period for the exemption from enforcement for residential dwellings. This change does not affect Wales, Scotland and Northern Ireland where the four-year rule will continue to apply. Any installation that was substantially completed before the introduction of the Act will still be subject to the four-year rule meaning, for most radio amateurs, the ten-year rule will not apply until the 24th of April 2028. For more information on planning matters visit rsgb.org/planning
Bath Based Distance Learning’s next Full licence course runs from August to December, with exams in January. There is no charge for the training, but applicants must work through some pre-course material and complete a quiz to be eligible for a place.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 22nd of August 2024
We had yet another week with a high solar flux and relatively calm geomagnetic conditions.
The solar flux index ended up at 239 on Thursday the 22nd, while the Kp index has been below 4 since Sunday the 18th. There are currently 11 active sunspot regions on the Sun’s surface and there is a 20% chance of a major X-class solar flare according to the NOAA Space Weather Prediction Center.
There are signs that HF propagation may be improving, but it will probably be another month or so before we see any large change. This is due to the summer doldrums that see the ionosphere harder to ionise due to a change in its chemical composition.
By mid to late September, we will start to see a change to autumnal conditions and DX will start to open up again on the higher bands. Having said that, there is still DX to be had. The N5J DXpedition to Jarvis Island in the Pacific Ocean proved that the DX is workable, but the path was mainly open to well-equipped stations with beams and linear amplifiers.
15m remains the best DX band and there are occasional openings on the 12m band. The 10m band may come into its own as we head into September and October.
According to the NOAA Space Weather Prediction Center, solar cycle 25 likely reached its highest sunspot number yet of at least 299 on the 8th of August. This may increase further, but we may be close to solar maximum.
Next week, NOAA predicts that the solar flux index will remain around 200 to 210. Geomagnetic conditions will depend almost entirely on the occurrence of coronal mass ejections, or CMEs. And, as we are at a particularly active part of the solar cycle, flares and CMEs are very prevalent.
And now the VHF and up propagation news from G3YLA and G4BAO
The overview for the coming week is that, although some fronts will affect the north and west at times, there are only a few that reach down to the southeast of Britain. This means that rain scatter is more likely in northern areas.
There will be weak high pressure over southern areas for much of the coming week and, although not enough for a full-blown Tropo event, conditions should be a little ‘up', especially for paths into the near continent or across the North Sea.
Meteor scatter is back to a more random approach since the broad peak of the August Perseids comes to an end. The solar conditions mean that auroras can be a possible element of operating excitement in the coming week. Remember to look out for a disturbed Kp index value of 6 or greater.
The last part of the sporadic-E season is playing out this week taking us to the end of the month. These 'last hurrahs' are usually characterised by QSOs of very limited duration on the 10m band, or perhaps up to 6m, and mainly over the southern half of Europe.
This usually favours southern UK stations but, notwithstanding the previous comments, some years have seen isolated Sporadic-E events in the first part of September. But they are certainly not reliable.
Moon declination is positive but still rising, reaching maximum on Wednesday, so long Moon visibility windows and high peak elevations continue. We are past perigee now, so path losses are increasing again. 144MHz sky noise is low but increasing to a moderate 500 Kelvin on Wednesday before falling back to low at the end of the week.
And that’s all from the propagation team this week.
The RSGB is looking for an individual to take on the complex role of Editor of the annual RSGB Yearbook, following the retirement of the previous Editor. This is a paid post, working part-time from home for a few months each year, and is offered as a fixed-term contract. You will need experience of editing material from a wide range of sources and working to deadlines, as well as having attention to detail. An understanding of desktop publishing programs such as InDesign will be helpful along with knowledge of the breadth of amateur radio in the UK today. If you are interested in this post, please email authors@rsgb.org.uk with an appropriate CV or covering statement of your abilities.
Last weekend was 1940s weekend at the Bletchley Park Museum. The RSGB National Radio Centre, or NRC, supported the event by hosting the World War Two Special Operations Executive radio station, GB1SOE. The station, operating on the 40m band, attracted lots of visitor attention, as did GB3RS which was busy on the air as part of the Museums on the Air weekend. NRC volunteers made QSOs and invited visitors to pass greetings messages. If appropriate, the volunteers used the new licence conditions to allow visitors to run QSOs themselves under supervision. The weekend was a huge success and 1,211 people visited the RSGB National Radio Centre. The Society would like to thank all the NRC volunteers who delivered such an enjoyable weekend.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 20th of June 2024
We had a relatively quiet week, with the Sun generally being settled. There were coronal mass ejections, but they were on the far side of the Sun and not Earth-directed.
There were no X-class flares, although we did have a few C- and M-class events.
The solar flux index declined to 167 but has since recovered and stood at 196 on Thursday the 20th. Active regions 3712, 3713 and 3716 are all large and 3712 has been emitting flares. However, all three regions will soon rotate out of view, so should not be a threat in the coming week.
As such, HF conditions have been reasonable given the time of year. Maximum usable frequencies over a 3,000km path during daylight have generally been between 14 and 21MHz, although there have been occasional openings up to 24MHz. Sporadic-E remains the main propagation mode on the 10m band.
Next week NOAA predicts that the solar flux index will remain in the 175 to 190 range and geomagnetic conditions are predicted to be mainly settled.
However, the far-side coronal mass ejections we have been seeing suggest we could be in for a rough ride in about a week to ten days. So, this week could be a good time for HF propagation.
And now the VHF and up propagation news from G3YLA and G4BAO
The weather is trying to change to a more summer-like pattern, which means that the main jet stream will be farther north than recently and this will make Sporadic-E harder to find than during the recent strong jet stream pattern over Europe.
For most UK stations, the emphasis on Sporadic-E paths will gradually shift from the typical central Europe and Mediterranean to perhaps Scandinavia and the Baltic states.
The relatively new player this time around will be high pressure which comes and goes during the period but should bring some useful Tropo. In these high-summer days, sea or coastal paths are often good, but paths across hot land do not fare well in summer during the daytime. Concentrate on the night or early morning, especially if it is foggy.
There will be occasions when small lows and fronts edge into the south and west of the British Isles and, in typical summer fashion, may bring a risk of thundery showers. Any local, heavy rain means good conditions for rain scatter on the GHz bands. Meteor scatter again remains in the random category, which usually peaks around the dawn period.
Lastly, a note about aurora which has been kept at arm’s length although there have been several periods with a slightly enhanced Kp index. The light summer nights mean that visible auroras are very unlikely but do look out for noctilucent clouds on the northern horizon around midnight.
Noctilucent clouds are thin, wispy clouds that glow with a blue or silvery hue at night when illuminated by sunlight from below the horizon.
The Moon is at minimum declination this coming weekend so peak elevation is low and windows of usage are short. EME path loss is falling as we approach perigee next Thursday the 27th. 144MHz sky noise is high this weekend but falls to low early next week.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 13th of June 2024
No sooner do we say that conditions will remain good than the Sun emits an X-class solar flare! Such is the challenge of writing propagation predictions.
Nevertheless, after the X1.5-class flare on the 10th of June, things settled again and, at the moment, there are no incoming coronal mass ejections, or CMEs for short, to report. With a Kp index of less than 1 on Thursday the 13th, and a solar flux index of 165, it looks like HF conditions could be quite good.
However, the Sun’s proton flux has increased and is close to the 10 million electron volts warning threshold. This means that paths through the polar regions might be disrupted. Protons can herald the arrival of a CME two or three days later, although NOAA is not predicting any disruption.
On the 13th of June, the critical frequency was between 7 and 8MHz, meaning a maximum useable frequency over a 3,000km path of around 21 to 24MHz. The 10m band will be open, mainly to Sporadic-E. However, F2-layer propagation on the 10m band will be sparse.
NOAA predicts the solar flux index will fall to around 155 today, the 16th, before climbing again to around 195 in a week. Geomagnetic conditions are predicted to be quiet all week, but that may be because solar flares and CMEs are hard to predict at this point in the solar cycle.
As always, make hay on the HF bands while the Sun shines! And make the most of the Sporadic-E propagation on the higher HF bands as June is probably a peak month for this.
Finally, the latest sunspot data show that the average sunspot number for May was 171.7, the highest in 22 years. However, the ARRL reports that shortwave conditions were above average on only six days out of the entire month of May, and mostly poor on half of the days due to geomagnetic disturbances and solar flares.
And now the VHF and up propagation news from G3YLA and G4BAO
The current spell of seemingly endless, poor weather is struggling to provide much Tropo. The general theme is low pressure bringing weather fronts with rain or, if not that, then scattered heavy showers.
This again points to rain scatter for the GHz Bands as the mode worth exploring. There is just one glimmer of Tropo hope in that the latest model predictions are starting to inject the notion of a ridge developing over southern areas, initially around mid-week but perhaps more so at the end of the week. Although, it's fair to say that other models hang on to the low-pressure theme. That said, it's worth checking from the middle of next week onwards.
There are no significant meteor showers this week so continue to check for random meteors around dawn.
The solar conditions have continued to trickle charge the auroral oval with an occasionally enhanced Kp index indicating possible aurora. This is unlikely to be visible at this time of the year although, if you are outside with a clear view to the north, you might be rewarded with a seasonal look at noctilucent clouds to make up for it.
High-summer Sporadic-E propagation is providing daily contacts so it’s worth checking the bands each day. The daily blogs always have something to show on the 10m band and many days there are reports of contacts on the 6m band. Remember these openings are not always reachable from all parts of the UK. One of the characteristics of Sporadic-E is that at each end of the path the ‘signal footprint’ is very small. Even in a busy opening, signals may still pass you by but you should continue to monitor in case a Sporadic-E path opens up that does include your station at one end!
Moon declination is negative again from this weekend, ending today the 16th. EME path loss was at its highest at apogee on Friday the 14th. 144MHz sky noise starts the week low but rises steadily, reaching over 3,000 Kelvin on Friday the 21st.
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 June 2024
It seems that we haven’t had a repeat performance of the auroral conditions caused by active sunspot region 3697. For Aurora watchers, that could be a disappointment, but for HF lovers it means the bands have been quite settled.
The Kp index has been at 3 and below, while the solar flux index has been consistently above 175 all week. As a result, HF conditions have been quite good with maximum usable frequencies over a 3,000km path being regularly over 21MHz and often 24MHz.
It is always a good idea to operate on the highest HF band that is open as absorption decreases the higher you go.
Meanwhile, Sporadic-E propagation brought interest to the 10m band with stations from all over Europe being workable for long periods, but more of that in the VHF report.
On the 5th of June, a filament located in the northeast quadrant erupted. The event flung a coronal mass ejection into space that doesn’t appear to be Earth-directed. But this shows that we are still in the danger zone for major solar events, and anything could happen.
Next week, NOAA predicts that the solar flux index will remain around 175, but we expect some geomagnetic disruption today, the 9th of June, with a predicted Kp index of 4. Otherwise, solar conditions are predicted to be calm next week.
So, if these conditions continue, this is a good time to make the most of the HF bands.
And now the VHF and up propagation news from G3YLA and G4BAO
The weather pattern for the coming week is dominated by low pressure, which means there is unlikely to be any significant Tropo to speak of.
There will probably be several opportunities for those on the GHz bands to search for rain scatter. However, these events look to be moving showers or rain bands, which means that you’ll need to be pretty agile with the rotator to keep on the scattering target.
With the solar conditions continuing to keep the pot simmering it's not impossible that the Kp index could rise high enough to promote an aurora, but it's a low probability.
The early part of June is well regarded for minor meteor events and should be worth a look for those using meteor scatter modes.
There were several Sporadic-E openings early in the week that finish today, the 9th. Sporadic-E was reported up to the 2m band on a few occasions. Last Sunday, the 2nd, lasted up to three hours on the path from Eastern England down to the Italian peninsula.
Events initially get picked up on the 10m band and then move up through the VHF bands of 6m, 4m and finally 2m as the Sporadic-E propagation strengthens. In this peak of the Sporadic-E season, the openings on the lower bands, such as 10 and 6m, can be present for much of the day and certainly quite late into the evening.
Follow the weather patterns on the daily Sporadic-E blog on propquest.co.uk and you should be able to point in the right direction for an opening. Multi-hop paths to the Far East or the Americas require a good antenna like a beam, but single-hop European Sporadic-E propagation can be very strong, and any antenna will do the job.
Moon declination is at its maximum this weekend for the DUBUS 10 and 24GHz EME contest, but EME path loss is rising. 144MHz sky noise is low all week.
And that’s all from the propagation team this week.
The RSGB Board recently spent an afternoon visiting RSGB Headquarters, meeting staff and gaining a more detailed understanding of the work of this professional team. Later that day, the Board received training from members of the senior team about their specialist areas. During the Board meeting the following day, the Board decided to continue with its chosen four strategic priorities until the 2025 AGM. These priorities are the growth of amateur radio; membership of the RSGB; spectrum and licensing; and ensuring the continued financial stability of the Society. To make further progress with the outcomes of the recent growth workshop, the Board allocated a member of its team to champion each of the seven workstreams. Each workstream champion will now create a volunteer team, prioritise work tasks, set measurable objectives, define what success looks like, list deliverables and establish reporting mechanisms and frequency. More details will be shared about these over the coming months.
Do you have some spare time to support fellow radio amateurs? Are you passionate about the future of amateur radio? Do you like a challenge? The RSGB currently has volunteer vacancies for Regional Representatives in Region 7 South Wales, and Region 12 England East and East Anglia. Could you fill one of those roles? To learn more about being a Regional Representative see the RSGB website or contact the Regional Team Forum Chair, Keith Bird, G4JED via rr10@rsgb.org.uk
Next week is the 40th anniversary of Volunteers’ Week in the UK.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 30th of May 2024
Last week was characterised by relatively quiet geomagnetic conditions and a fairly high solar flux. But is that all about to change?
Active region 3664 has returned. It is now named 3697 and has already emitted an X1.4-class solar flare. You may recall that it was AR 3664 that caused the aurora that was visible all over the UK around the 10th and 11th of May.
As Solarham.com says, “The chances for an Earth-directed eruption will increase with each passing day as the active sunspot region turns into a better geoeffective position.”
Scientists now believe that the coronal mass ejection associated with the long-duration X1.4-class flare on Wednesday the 29th may pass close enough to Earth to generate moderate G2 geomagnetic storming beginning on the 31st of May – just in time for this weekend’s National Field Day!
Otherwise, HF propagation has generally been good with decent F2-layer openings up to 21 and even 24MHz at times.
The 17 and 15m bands look to provide the best DX, with paths to the east in the morning, and to the west during late afternoon and early evening.
The 10m band is subject to Sporadic-E openings, with F2-layer openings mainly restricted to paths to South Africa and South America.
Next week, NOAA predicts that the solar flux index will be in the 165 to 200 range, with quiet geomagnetic conditions. However, that is perhaps a little optimistic as active region 3697, or perhaps 3691, could easily throw a spanner in the works, with a flare and associated CME potentially sending the Kp index skywards.
So, as always, keep an eye on the current state of the Sun at solarham.com, and work the bands while they are open!
And now the VHF and up propagation news from G3YLA and G4BAO
The close of the current week offers a temporary return of high pressure for this weekend. This should be good for some Tropo conditions for western parts of the UK. The weather turns a bit more unsettled going through the coming week, especially over northern Britain, but also occasionally in the south.
Rain at this time of the year can often be heavy and thundery with good prospects for GHz bands rain scatter, but this may have to wait for the end of next week when a low moves north from France towards the southern UK.
The early part of June is a time of several minor meteor showers. These should offer scope for meteor scatter operators as well as provide some fuel for Sporadic-E propagation which rocket measurements show consists of long-lived meteor ions.
Sporadic-E propagation is often associated with the position of jet streams in the upper troposphere due to the turbulence that these fast-flowing currents of air generate.
In the coming week, the jet stream pattern becomes much weaker, although still with a few options. Daily blogs are available at Propquest.co.uk for those who are interested.
Don’t ignore the prospects for multi-hop transatlantic paths to the United States and particularly the Caribbean, which are usually well supported in the early part of the season before the upper winds over the Caribbean change over to high-summer slacker flow.
Equally, multi-hop Sporadic-E paths to the Far East are worth checking in the early morning following the effects of the now displaced northerly meandering jet stream flow across northern Russia.
Moon declination went positive again on Saturday the 1st of June, so the coming week will see lengthening Moon windows. EME path loss is falling, reaching a minimum at perigee today, Sunday the 2nd of June. 144MHz sky noise is low apart from Thursday when the Sun and Moon are close in the sky.
And that’s all from the propagation team this week.
British Science Week is an annual event run by the British Science Association celebrating science, technology, engineering and maths. The event, which is taking place between the 7th and 16th of March 2025, will have the theme ‘change and adapt’, which lends itself perfectly to amateur radio in the 21st century. As part of its commitment to encourage new radio amateurs into the hobby, the RSGB will again be providing resources and activities to inspire people of all ages to get involved. The RSGB is now collecting ideas for activities for primary and secondary schools, or for use with the wider community.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 22nd of May 2024
After the extremely unsettled HF conditions on the 10th and 11th of May, it was gratifying to see things returning to normal last week.
The Kp index has returned to being in the range of 1 to 4 and, with a solar flux index still in the 190s, we have seen some good propagation around the world.
But make no mistake – it probably won’t last!
Active region 3664, the source of so much mayhem a couple of weeks ago, will soon return from its trip around the Sun. It has probably been the source of a major flare while on the Sun’s far side and there is a good chance we may get a repeat performance of last month.
Meanwhile, make hay while the Sun shines!
NOAA predicts that the solar flux index will increase above 200 next week, but unsettled geomagnetic conditions are forecast for tomorrow, the 27th of May, and at the end of the month and into early June.
Daytime critical frequencies have been between 8 and 9.3MHz, making 40m a good band for inter-G QSOs. These have also meant that the maximum usable frequency over a 3,000km path has often exceeded 24 to 27MHz, making 12m a viable band for DX. Note that this is a little patchy, so if you don’t hear anything on 24MHz just wait a while or check later.
Nighttime critical frequencies are usually around 6 to 7MHz, meaning 20m is generally open all night with occasional openings on 17m.
We are now well into the Sporadic-E season so there should be lots of short-skip into Europe on the 12 and 10m bands to play with.
And now the VHF and up propagation news from G3YLA and G4BAO
The end of the current week, in the lead-up to the bank holiday weekend, shows a low and its thundery rain moving north and leaving behind a slack area of pressure with a weak trend towards building a ridge over the country.
The bulk of next week is showing up with a slack westerly pattern and weak fronts brushing past. From midweek, and towards next weekend, the frontal systems will be more active with longer periods of heavier rain possible.
The end result for most VHF and up operators is that there may be some occasional Tropo events, especially overnight during the slacker period with the weak ridge over the country by the start of the weekend.
A more likely option will again be rain scatter which will produce better scattering from the larger raindrops now the summer season is upon us, and thundery developments are more common. Check the many online weather radars for your tracking beam headings.
Meteor scatter will also be worth considering since we are approaching the period when many lesser showers appear to pep up the background meteor count. This will be useful for meteor scatter operators and serve the Sporadic-E folk well.
The solar activity continues to deliver random events which take the Kp index to high values. Remember that a Kp index greater than 5 indicates the chance of aurora propagation.
The primary mode at this time of the year is Sporadic-E. The late May and early June period is often regarded as a peak time for monitoring your favourite VHF beacons. As many will know, the 10m band is a useful starting point for identifying the beginning of an opening, and then you should check the higher bands in turn as the event strengthens. This is often indicated by the skip distance shortening on the 10m band.
The other basic operating tip is to use the daily blog on the Propquest.co.uk website for commentary on the effectiveness of the various upper air patterns such as jet streams, which can influence the location where Sporadic-E propagation occurs.
There are no major meteor showers this week so, in between the Sporadic-E, look around dawn for the best random meteor prospects.
Saturday the 22nd sees the lowest Moon declination of the month so next week will see some lengthening Moon windows. EME path loss is falling, but we are still over a week from perigee, its closest point to Earth. 144MHz sky noise starts the week high, as it reached over 2500 Kelvin on Saturday the 25th. It is low for the rest of the week.
And that’s all from the propagation team this week.
Don’t forget that lots of stations are on the air to celebrate SOS Radio Week throughout May. The event takes place each year to celebrate the work of the volunteers from the Royal National Lifeboat Institution, Independent Lifeboats and National Coastwatch Stations around the British Isles. A commemorative certificate is available to all official stations that record their contacts on the website together with awards for the top individual and club, or group, stations on each band from 160m to 70cm.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 16th of May 2024
After last weekend’s auroral spectacular, it was nice to see the Sun calm down a little and the bands get back to normal. But that didn’t last long.
To recap, on Friday the 10th of May the Kp index shot up to 9, due to the effects of a number of coronal mass ejections, while the HF bands closed down in the subsequent geomagnetic storm.
While there was visible aurora across the UK and Europe, HF propagation suffered and didn’t start to recover until the late afternoon on Saturday the 11th.
The main culprit, active region 3664, has now rotated out of view, but that doesn’t mean we are out of the woods just yet.
Solar flares can cause short-term disruption to HF propagation due to their X-rays penetrating deep into the D-region and causing signals to be absorbed. Subsequent coronal mass ejections can cause longer-term degradation of the F2 layer with reduced maximum usable frequencies, noisy bands and auroral conditions.
At the time of writing, the Kp index stood at 6 again so it looks like unsettled geomagnetic conditions are continuing with a moderate G2 geomagnetic storm in progress.
Low to moderate activity is now expected, with a slight chance of further strong-class flares. The regions currently on the visible disc are smaller and simpler, with isolated M-flares possible from these. However, a new active region, now rotating into view, has already emitted an X-class solar flare.
Next week, the United States Air Force predicts that the solar flux index may remain in the 160 to 180 range. HF conditions remain a lottery as they can be badly affected by solar flares and coronal mass ejections.
It is best to keep an eye on solarham.com for updates, and also propquest.co.uk for near real-time reports of the critical and maximum usable frequencies.
And now the VHF and up propagation news from G3YLA and G4BAO
The weather remains on the unsettled side of things with areas of rain and some thunderstorms over the country, especially the south as we end this week. As this report is being read out, high pressure is becoming established over northern and western Britain.
This may eventually take a tenuous hold over the rest of the country during the second half of the coming week and into next weekend, the 25th and 26th.
This high pressure, although fairly weak, may help with some Tropo for those in northern Britain in the 144MHz May Contest and the Backpackers Contest this weekend, ending on the 19th. It may also be helpful to those taking part in the 1.3GHz UK Activity Contest on the 21st. However, the conditions may not be of much use in the south as another low arrives from the continent.
Overall, rain scatter on the GHz bands will probably be worth exploring in the rainy areas again, since some of the showers may be heavy and thundery.
The prospects for Aurora are still worth keeping in mind despite the recent stunning event. Minor non-visible events can still provide a reasonable radio aurora to explore.
The Sporadic-E season continues to develop. And with such unsettled weather, there are plentiful jet streams to act as source regions for turbulence, which can propagate up to the E region where they can generate Sporadic-E.
We are currently at the tail end of the Eta Aquariids meteor shower. A few meteors from this shower will continue to appear, but no major shower is expected this week.
The lowest Moon declination occurs this coming Friday. With the Moon being full on the 23rd, a clear sky should reveal an impressive ‘Flower Moon’.
For EME, path loss will still be relatively high, although the Moon is starting to move back towards its closest point to Earth, or perigee.
144MHz sky noise starts the week low but rises to high on Saturday the 25th.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 9th of May 2024
Disrupted solar conditions continued this week with X-class solar flares aplenty.
Four X-class events on the 8th and 9th of May prompted coronal mass ejections, which could join together to impact the Earth this weekend. We can expect a strong G3 event with the Kp index rising to 6 and the potential for visible aurora in the UK.
It’s hard to be positive about this as HF conditions this weekend, ending today the 12th, are likely to be very disrupted with reduced MUFs and noisy bands.
But do look out for auroral signals, perhaps on the 10m band, and above, and a potential HF band enhancement just as the plasma cloud hits.
The solar flux index hit 227 on Thursday the 9th, which is one of the highest we have had in this cycle. But don’t get carried away as it is forecast to decline.
Meanwhile, conditions have been typical for this time of year, with reduced F-layer propagation on the 10m band, offset by the start of the Sporadic-E season. The lower HF bands are staying open later in the evening, and may even increase to all night on the 20m band, as we head towards June and July.
Next week, NOAA predicts that the solar flux index will drop below 200, but remain at or above 175 all week. After this weekend’s chaotic geomagnetic conditions, we can expect the Kp index to fall to 2, but increase again on the 13th, to perhaps 4.
In the meantime, solar maximum is still predicted to be later this year, although geomagnetic disturbances are likely to increase on the downward part of the cycle. So, buckle up for a rough ride!
And now the VHF and up propagation news from G3YLA and G4BAO
We end the current week with high pressure over the country and some occasional Tropo paths, especially over surrounding waters. The high will decline from the west as we progress through this weekend.
At the time of reading on Sunday, the transition will be all but complete and low pressure will remain in control for much of the coming week. This means periods of rain, heavy showers or thunderstorms and quite windy weather at times. In terms of propagation, a shift to rain scatter is a good choice for those equipped for the GHz bands for the week ahead.
Recent solar activity continues to offer chances of auroras so remember to monitor the Kp index and check for fluttery signals on the HF bands and raspy signals on VHF. The many clusters and band reports should be a good tool for these conditions.
Lastly, the Sporadic-E season is having a few starting twitches. Earlier in the evening of Wednesday the 8th there was a short opening of about an hour to Scandinavia on 6m CW from a patch in the middle of the North Sea. The positions of the jet streams may not entirely suit further openings in the shorter term but, as the low-pressure moves in next week, things could improve for Sporadic-E paths to Iberia and central Mediterranean.
With the Eta Aquariids peak now past, the next big meteor shower isn’t until July with the Delta Aquariids. But before the Delta Aquariids, we can look forward to the Arietiids in late May.
However, the Eta Aquariids will continue to produce the odd ping or burst. Last week there was plenty of evidence of meteors continuing to burn up after the peak. There may still be the odd one during the coming week together with the usual background sporadic meteor returns.
As the Moon starts to decline this week, the distance between the Moon and Earth is also beginning to increase and with it the path loss increases to a maximum on Friday the 17th and Saturday the 18th. However, sky noise will remain low all week. The Moon is favourably placed for daytime operation this week.
And that’s all from the propagation team this week.
The next in the series of the popular 145 Alive events, to promote the use of 145MHz FM, is coming up on Saturday the 11th of May, from 1pm to 3pm.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 2nd of May 2024
What a strange week we had. With the solar flux index in the 167 range, falling to 130, conditions should have been reasonable. But the Kp index hit 4, and even 5.33, on the evening of Friday the 26th of April, which meant propagation on Saturday the 27th was truly dire.
Stations taking part in International Marconi Day on the 27th found the 40m band only open to long skip in the morning. This was due to the critical frequency being below 5MHz. The predicted MUF over a 3,000km path fluctuated between 15MHz and 19MHz for the whole day, which meant only 14MHz was open reliably. As a result, QSOs were hard to come by and many stations reported that it was slow going with virtually no signals from outside of Europe.
So what happened? Well, it was a combination of factors. The increased Kp index, due to a fast solar wind, took its toll. And we are now moving to a summer ionosphere, where chemical changes make it harder to ionise. This will mean we should see MUFs dropping as the season progresses, at least during the day. Nighttime MUFs will be higher than in winter.
So it may be that the glory days of 28MHz F2-layer propagation are on hold until Autumn, with only short-skip Sporadic-E on the 10m band to keep us entertained.
F2-layer propagation is still available on the higher HF bands, but it may be patchy.
International Marconi Day station GB0CMS in Caister, Norfolk, reported that its 20m signals were picked up by a reverse beacon network skimmer in Utah, despite not working anyone outside of Europe. Meanwhile, on the morning of the 2nd, Laurie, G3UML was quite surprised to work YJ0CA on Vanuatu on the 15m band using SSB. He also worked 3D2CCC on Conway Reef on the 20m band using CW, and JD1BMH in Japan on the 15m band, also using CW.
Next week NOAA predicts the solar flux index will be in the 125 range, rising to 175 as the week progresses. Geomagnetic conditions are dependent on coronal mass ejections. We have had eight M-class solar flares in the past three days, and a Kp index of 5 on Thursday the 2nd, which doesn’t bode well for next week. So, keep an eye on solarham.com for current conditions and look for the best HF propagation if the Kp index is low for a day or two.
And now the VHF and up propagation news from G3YLA and G4BAO
The weather pattern remains very unsettled for the whole period with areas of low pressure edging north across the UK from the continent.
There will be a risk of thundery weather at times with locally heavy rainfall, which will be good for rain scatter on the Gigahertz bands. Tropo looks to be hard to find as we end the current week dominated by low-pressure systems, but there are signs of high pressure returning after mid-week, but only temporarily.
This could produce some Tropo paths, especially across surrounding waters such as the Irish Sea, English Channel and North Sea.
The nominal summer season of Sporadic-E propagation is upon us and, from May to early September, daily blogs will be provided on the Propquest.co.uk website highlighting the possible Sporadic-E links to the position of the jet streams shown on the upper air charts.
It’s well worthwhile getting into the habit of regularly checking the DX clusters and activity maps, since the early season is usually characterised by a complex jet stream pattern with multiple potential locations for Sporadic-E propagation.
Timewise, it eventually settles into a more traditional behaviour with activity often in two phases, one in the morning and the second in late afternoon, early evening.
As you listen to this report, the Eta Aquariids meteor shower should be peaking. Unfortunately, the best viewing for the shower, which is part of the debris from Halley’s comet, will be in the southern hemisphere.
Nevertheless, this is expected to be one of the best showers this century. For those viewing the shower, a waning Moon means that light levels should be low, making for ideal visual sighting.
For EME, the Moon will be waning all week with the new Moon around the 8th of May. The Moon will be rising in the sky throughout the week, with zero declination on the 5th of May and peaking at its highest in the sky on Saturday the 11th of May.
The lowest additional path loss occurs today and tomorrow, the 5th and 6th, but high Sun noise, with the Moon close to the Sun at new Moon, occurs shortly afterwards. Later in the week, as the Sun 'leaves' the Moon behind, noise levels, at least on the higher bands will fall to around normal.
And that’s all from the propagation team this week.
