The outcome of the RSGB 2024 Board and Regional Team election process
RSGB challenge for British Science Week announced
RSGB Spectrum Forum updates
The RSGB has announced the outcome of its 2024 Board and Regional Team election process. These results come into force at the RSGB 2024 AGM and, until that time, the current Regional Representatives remain in their roles. The announcement also contains news of the Nominated Directors put forward for endorsement by the RSGB membership next month, as well as two co-options to the RSGB Board, effective until the AGM. For full details of the announcement and the candidates go to the RSGB AGM web page at rsgb.org/agm
The theme of British Science Week this year is Time. Both time and the closely related concept of frequency, are of vital importance to radio communications. The RSGB has announced a new challenge for British Science Week linked to this theme. The challenge has categories for every age group and the winner of each group will win a prize. The deadline for entries is the 1st of September and the results will be announced at the RSGB Convention in October. The challenge is as follows: “Using readily available components, material or other resources, provide a method of either measuring the frequency of a radio frequency source or signal or providing a time reference to a radio operator or radio system”. For more details about the challenge, as well as activities to inspire you and resources to help you take part in British Science Week, go to the RSGB website at rsgb.org/bsw
A busy year has seen several online Spectrum Forum meetings. Two meetings held in January considered the Ofcom notice period for ‘representations’ and areas where band plan adjustments would be needed, as well as more regular items such as annual group reports.
The RSGB website now has these details online. The RSGB’s reply to Ofcom has been added to its special focus page on the Ofcom licence review. Along with other recent representations, this will enable Ofcom to finalise the new licence later this month. The RSGB Spectrum Forum pages have also been updated with the January 2024 group reports and meeting notes, which included the discussions on the provisional changes. To read more, visit rsgb.org/spectrumforum
As previously announced by the RSGB Examinations Standards Committee Chair, Tony Kent, G8PBH, the amateur radio licence examinations will need to change to reflect the changes to the licence conditions announced by Ofcom. The scale of the licence changes will have a significant impact on Section 1 of the syllabus, ‘Licensing’, and a small impact on Section 7, ‘Operating’. Ofcom is currently reviewing representations and will publish its final decision, including the final version of the licence, before the 21st of February. The new licence will come into effect before work on the syllabus and examination question bank is completed. The RSGB Examinations Standards Committee has gained approval from Ofcom to continue to examine the current licence conditions for a period of six months following the publication of the new licence. This will allow trainers time to update their courses in line with the new syllabus, and allow candidates that have started their training under the current licence conditions to complete their courses and take the exam. It is expected that examinations of the new licence conditions will begin on the 1st of September 2024. For full details, see the exam announcements page on the RSGB website.
The first amateur radio station on the moon, JS1YMG, is now transmitting. The Japan Aerospace Exploration Agency, or JAXA, landed its Smart Lander for Investigating the Moon on the 19th of January 2024. The JAXA Ham Radio Club, JQ1ZVI secured the JS1YMG callsign and has been transmitting Morse code on 437.41MHz since the 19th of January. The probe uses 1W to a UHF antenna, with circular polarisation, and is transmitting what is described as "matters related to amateur business." Radio amateurs have been busy analysing JS1YMG's signal. You can read more about this story on Daniel Estévez, EA4GPZ’s blog at destevez.net

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 8th of February 2024
A large sunspot region has been turning into an Earth-facing position and now looks like it could be threatening. Active region 3576 has already emitted a couple of low-class solar flares but could be poised for even more.
An M5.1 solar flare was detected around region 3575 on the 7th of February as well. Updated imagery shows that an associated coronal mass ejection, or CME, was likely however, due to the location near the Sun’s south-west limb, it was directed mostly away from Earth.
The solar flux index remained high this week, hitting 190 on the 6th before dropping to 188 on the 8th. Geomagnetically, the Sun has been behaving itself with a maximum Kp index of only three on Sunday the 4th.
But all eyes will be on active region 3576 next week as it could upset the apple cart.
Meanwhile, daylight maximum usable frequencies over a 3,000km path remain more than 28MHz, which is good for HF.
Next week, NOAA predicts that the solar flux index may decline to be in the range of 160 to 170. Geomagnetic conditions are also predicted to be settled with a low Kp index. However, as we said earlier, that could all change if we have a violent solar flare and associated coronal mass ejection from region 3576 or any of the many other sunspots.
And now the VHF and up propagation news from G3YLA and G4BAO
Unsettled weather describes the pattern for the coming week, including some colder weather mixed in to provide snowfall for some areas, particularly in northern areas. This characteristic weather type will mean little chance of Tropo during the period.
Other propagation modes of interest might be even harder to find unless you are thinking of rain scatter, which could be useful for a few suitably-equipped stations on the GHz bands. Other modes, such as meteor scatter or aurora, are also looking a bit thin. There is always the chance of some random activity, unlike Sporadic-E which is in its late winter lull that usually lasts until April for the 10 and 6m bands.
For EME operators, Moon declination is negative and rising, going positive on Monday the 12th. So there will be higher peak Moon elevations and longer Moon windows throughout the week. Path losses were at their lowest at perigee on Saturday the 10th.
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 1st of February 2024
We had another week of relatively calm geomagnetic conditions with a maximum Kp index of three. The solar flux index declined from 172 on the 24th to 135 on the 30th.
Nevertheless, that is still enough to support propagation on the 10m band, with the maximum usable frequency over a 3,000km path generally being between 29 and 36MHz during daylight.
Solar activity has been at low levels with only minor C-class flares and one M-class flare detected. Active region 3559 is now located behind the west limb of the Sun and out of direct view. New active region 3567 in the northeast quadrant is showing the most promise as it appears to be in a growth phase. There is currently a 25% chance of a moderate M-class flare, according to the latest NOAA and SWPC update.
Earlier in the week, we had a period of moderate S2-level radiation storming. Proton levels streaming past Earth, following a solar flare early on Monday morning, increased but this has now declined.
A minor coronal hole also became Earth-facing on the 2nd of February, so we may still expect some disruption today, Sunday the 4th.
The 10m band is still romping along, with beacons along the eastern seaboard of the USA coming alive in the afternoon. This weekend, the 3rd and 4th, sees the 10-10 International Winter SSB Contest, so there should be plenty of stations to work on 28MHz.
Next week, NOAA predicts that the solar flux index may rise again, perhaps to 150 today Sunday 4th, and up to 165 a week later. We may have unsettled geomagnetic conditions on the 5th and 6th, with the Kp index predicted to rise to three.
And now the VHF and up propagation news from G3YLA and G4BAO
This week, ending the 4th of February, saw high pressure to the south of Britain and fronts over northern areas. For some stations in the southern half of the country, there could be useful Tropo conditions for the 432MHz Affiliated Societies Contest taking place today, the 4th.
Unfortunately, the frontal activity over the north will move south on Tuesday to remove any chance of these better conditions lasting into the 144MHz UK Activity Contest on Tuesday the 6th of February.
The period from mid-week onwards looks dominated by low pressure with rain or showers and generally flat VHF and UHF prospects unless you are set up for rain scatter. Other propagation modes like meteor scatter, aurora or Sporadic-E seem likely to remain in the background for the coming week.
For EME operators, moon declination is negative and falling to a minimum on Tuesday the 6th. Path losses are also decreasing since their maximum at apogee on Monday the 29th. But with the low peak moon elevations, only eight degrees on Tuesday, moon windows will be short.
144MHz sky noise is moderate to very high all week going over 3100 Kelvin on Tuesday the 6th. Friday and Saturday see the moon and sun very close together, so Sun noise in antenna beamwidths will be an issue.
And that’s all from the propagation team this week.

The RSGB election deadline is coming up
RSGB Build a Radio workshop planned at Bletchley Park
Registration for SOS Radio Week is open
The deadline for nominations in the RSGB elections is next Wednesday, the 31st of January. If you would like to stand for the one elected Director role, or any of the eight Regional Representative vacancies, you will need to complete the nomination process by 2359UTC on Wednesday. Full details of the process are on the RSGB website at rsgb.org/election The Society would encourage anyone with a passion for amateur radio, and a desire to support the amateur radio community, to look at the candidate information and consider stepping forward for one of these roles. You’ll find full information about the skills and experience needed in the candidate packs, and there is still time for an informal chat about the roles and responsibilities if you’d like one. But don’t delay as late applications won’t be accepted!
As part of its British Science Week activities, the RSGB is organising two build-a-radio workshops at Bletchley Park on Sunday the 17th of March. Funded by the Radio Communications Foundation, these fun workshops are a great way for young people to try a practical amateur radio activity. The sessions are for youngsters aged 11 to 18 who will build their own VHF FM broadcast receiver using simple tools. The workshops cost £11 for the participant, and if you are an adult accompanying a participant who is aged 16 or under, you will receive free admission to Bletchley Park. These workshops are always very popular so book now if you know a youngster who would like to take part. Go to the Bletchley Park website at bletchleypark.org.uk then choose the What’s On option from the top right-hand menu.
SOS Radio Week is an annual event that takes place throughout May to celebrate the work of the volunteers from the Royal National Lifeboat Institution, Independent Lifeboats and National Coastwatch Stations around the British Isles. Members of these organisations save many people who are in danger along, and around, the thousands of miles of coastline and further out to sea. This year is the 200th anniversary of the founding of the RNLI, so SOS Radio Week is being branded ‘SOS Radio Week 200’ for those operators who are supporting the RNLI during the event. Participants can operate from home, a public location, or a lifeboat or Coast watch station, with the appropriate authorisation from the station manager. A commemorative certificate will be 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. Registration for individual and group operators is now open via sosradioweek.org.uk
The RSGB has released a further three presentations from its 2023 Convention. In the first, Professor Simon Watts, G3XXH gives a fascinating presentation about VHF airborne radar and the design and performance of these early systems in World War II. The other two presentations focus on the World Radiosport Team Championship which the UK will be hosting in 2026. The WRTC is held every four years and is considered to be the Olympic Games of radio contesting. At the RSGB Convention, WRTC Chair Mark Haynes, M0DXR gave an overview of what is being planned and how people can get involved either as a spectator, volunteer, competitor or referee. John Warburton, G4IRN gave his perspective on what it is like to be a WRTC referee. The full WRTC planning team also gave an update recently on an RSGB Tonight@8 live webinar. You can see all of these presentations on the RSGB YouTube channel at youtube.com/theRSGB
RadCom Basics aims to help newcomers to amateur radio develop their knowledge and experience. Others enjoy reading it as it helps remind them of things they have forgotten or practise a skill they have not used for a while. The January 2024 issue of RadCom Basics is now available. It contains articles that provide advice on getting started with Bunkers on the Air, working on the 160 and 80m bands, constructing a multi-band vertical antenna, and more. You can find RadCom Basics at rsgb.org/radcom-basics
The latest issue of RadCom Plus, the online magazine for the more technically-minded radio amateur, was published this week. The first article, by Tom Alldread, VA7TA, is about how to make a protection filter for an SDR or VNA. Following this is a contribution from Sheldon Hutchison, N6JJA who discusses how to make an effective antenna noise canceller. You may recall the article by Andy, G0FVI in October’s RadCom which discussed the principles of antenna noise cancellation. Sheldon investigates exactly how the canceller should work, and his investigations have resulted in his superior design which you can construct for yourself. The third article, by Michael Toia, K3MT, is all about understanding the relationship between a train of square pulses and the harmonic content of its frequency spectrum, not with complicated mathematics, but by using an entirely diagrammatic approach. Those less familiar with mathematics might especially find this article helpful. This issue of RadCom Plus ends with Andy Nehan, G4HUE discussing the design of analogue power supplies. Members of the RSGB can access RadCom Plus via rsgb.org/radcom-plus

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of January 2024
We dodged a bullet last week when a coronal mass ejection, or CME, was predicted to be heading our way. In the end, it came to nothing.
The CME observed on the 20th of January was expected to pass Earth and deliver possible G2 storm conditions. But a solar wind enhancement, possibly associated with the plasma cloud passing near Earth, saw the Kp index rise to only 3.67 on Wednesday the 24th.
The many solar flares, and associated coronal mass ejections, over the past few days make it difficult to give a reliable geomagnetic forecast. Over the past seven days, there have been more than 60 C-class and 18 M-class flares, typical for this point in the solar cycle. Sunspot-wise, the solar flux index has remained high, being more than 170 all week.
Critical frequencies have often exceeded 11MHz during daylight hours, which means the 30m band, as well as the 40m band, should be open around the UK. However, nighttime critical frequencies have fallen below 4MHz, meaning that even the 80m band struggles at times.
We mentioned last week that the NCDXF beacon VK6RBP in Australia had been heard on 28.200MHz. If you’ve copied VK6RBP you might be interested in trying for some other lower-power Australian beacons on the 10m band. Try listening for the 8W VK4LA/B on 28.206MHz in Brisbane, or perhaps the 10W VK4RST, which is 550km north-west of Brisbane, on 28.266MHz.
Next week, NOAA predicts the solar flux index will be in the range of 155 to 175. Geomagnetic conditions are forecast to be quiet, other than on the 29th of January when the Kp index is predicted to rise to three. But, as always, keep an eye on solarham.net for a near real-time report.
And now the VHF and up propagation news from G3YLA and G4BAO
Today, the 28th, sees the UK recovering from the two named storms and just getting settled into moving high pressure across northern France, with a second centre crossing central Britain early next week. This offers a chance of Tropo, especially in the south, while fronts continue to affect Scotland.
After the middle of the coming week, a more unsettled pattern returns with fronts crossing the country, which might bring some rain scatter for the GHz bands. But, in general, the picture remains unsettled into the end of the week and doesn’t look too exciting for the 432MHz Affiliated Societies Contest on Sunday the 4th of February.
Other propagation modes that are worth considering are all relatively low-key in the transition into February. This means that meteor scatter is best looked for in the early pre-dawn period when random meteor activity peaks.
The other chance might be aurora, and this is simply about checking the behaviour of the Kp index, which measures the disturbance of the earth’s magnetic field by solar activity. Kp indices higher than six are a good sign for aurora.
It looks like we are in a quiet period for Sporadic-E propagation.
For EME operators, Moon declination is positive and falling, going negative again on the 30th. Path losses reach their maximum at apogee on Monday the 29th, then start to fall again. 144MHz sky noise is low all week.
And that’s all from the propagation team this week.

British Science Week is approaching
Updates on the RSGB’s Strategic Priorities
RSGB election deadline reminder
This year’s British Science Week runs from the 8th to the 17th of March with the theme of Time. This event is a fantastic opportunity to raise awareness of amateur radio in your local area. The RSGB has some great activity ideas you could try at your local school, Scout or Guiding group or local youth club. Go to the web page at rsgb.org/bsw and click on the activity titles to find everything you need to know to be able to run that activity. Several radio clubs from across the UK have already planned outreach activities for British Science Week and the RSGB hopes its resources will inspire you to get involved too! RSGB volunteer John Hislop, G7OHO has provided these ideas but the Society would love to add other activities to enthuse young people about wireless communication. If you have an amateur radio activity on the theme of Time that you’d like to share, or if you’d like to get involved but aren’t sure how to start, please direct enquiries to the RSGB British Science Week contact, Ian Neal, M0KEO. Ian’s contact details will soon be available at rsgb.org/bsw
At the Discussion with the Board session at the RSGB 2023 Convention, the RSGB President, John McCullagh, GI4BWM confirmed that the Board would keep members updated regularly on progress with the new strategic priorities. Two updates have now appeared in the January and February issues of RadCom and they are also available to read on the RSGB website. These updates highlight some important activities and achievements as well as new plans, so the Society encourages every member to take the time to read them. Go to rsgb.org/strategy and choose the ‘Strategy priorities updates’ option from the righthand list. Further updates are being prepared so do check back regularly or look out for them in each RadCom. You can also watch the Discussion with the Board Convention session on the RSGB’s YouTube channel at youtube.com/theRSGB
The deadline for applications for the one elected RSGB Board Director position and eight Regional Representative roles is Wednesday the 31st of January. Amateur radio needs a strong and active national society so don’t leave it to everyone else, step forward for one of these roles and play your part in the future of the RSGB. You'll find guidance and candidate forms on the RSGB elections web page at rsgb.org/election as well as contact details if you want an informal chat before standing for election.
A reminder that the RSGB is looking for four licensed radio amateurs to help raise the profile of wireless communication amongst young people across the UK. We have had a good response, but we’d still like to hear from prospective volunteers in Northern Ireland and Wales. These volunteer Youth Country Representatives will represent the RSGB at externally organised events and will plan and deliver outreach activities. If you have plenty of ideas, a passion for getting young people involved in amateur radio and experience of running small-scale events, we would be very keen to hear from you. The deadline is Friday the 16th of February. For full details, see rsgb.org/volunteers and for an informal discussion, please email RSGB Board Director, Ben Lloyd, GW4BML at gw4bml@rsgb.org.uk
GB2RS began broadcasting via the Es’hail-2 amateur satellite in May 2021. Every Sunday at 0800UTC you can hear the latest RSGB news on the dedicated narrow-band QO-100 transponder frequency of 10489.855MHz. This has proved so popular that, by the kind permission of AMSAT-DL, from the 4th of February 2024 we’re introducing a second reading at 2100UTC. This will suit our international audience in the western lobe of the footprint. The existing team of three Newsreaders is looking for another volunteer to join them. If you are an RSGB member with a good QO-100 facility and would be interested in broadcasting the news, please contact the GB2RS Manager, Steve, G4HPE at gb2rs.manager@rsgb.org.uk for further details.
During February, the RSGB’s Photo Friday focus on social media is all about clubs. If you’d like your club to be included, let the RSGB comms team know what you've been up to and who's been involved and share all the brilliant things you've been doing. Email comms@rsgb.org.uk by the 31st of January with a brief summary of the activity and some photos, and please make sure that everyone in the photo is happy to have their face on social media!
Chris Deacon, G4IFX has been awarded a PhD from the University of Bath after completing research on propagation. His thesis was entitled: “Radio propagation through ionospheric Sporadic-E”. This part-time work over many years involved looking at Sporadic-E on the 6m band, including making novel measurements of signal amplitude, phase, derived Doppler, polarisation and potential time delay to discover the nature of sporadic-E propagation at VHF frequencies. The RSGB Propagation Studies Committee congratulates Chris on this fantastic achievement. You can find out more by searching for Chris’ name on the University of Bath research portal at researchportal.bath.ac.uk Chris has done a number of presentations about propagation at RSGB Conventions over the years, which you can see on the RSGB YouTube channel at youtube.com/theRSGB

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 18th of January 2024
We had yet another week with good solar conditions which, at this point in the cycle, is good news. The solar flux index remained in the 170s to 180s range and the Sun is currently peppered with spots.
The Kp index never got above 3.33 and that was only for one three-hour period on January the 16th.
We were also lucky with solar flares in that we only had minor C-class flares to contend with. An eruption was observed beyond the west limb on January 14th. The event generated a fast-moving coronal mass ejection or CME, but it was directed away from our planet.
Daytime MUFs over 3,000km remain high at more than 28MHz. At night this reduces to around 6.9 to 9.5MHz, meaning only the 40m band is mainly open to DX, if at all.
HF-wise, this is the best time for low-band DXing, such as 40m band contacts with New Zealand around sunrise, and overnight QSOs on the 80m band with the USA.
Other DX being worked by members of CDXC includes XU7AKU in Cambodia on 40m CW in the early evening; V31XX in Belize, VP9KF in Bermuda, on 30m CW around 1000UTC; and E20AX in Thailand on 40m CW around 0930UTC.
Next week, NOAA predicts that the solar flux index may remain in the 160 to 170 range with a maximum Kp index of 2. As always, take that Kp prediction with a pinch of salt as a single Earth-facing coronal mass ejection could send it sky-high with an accompanying lowering of the MUF and generally poor conditions.
And now the VHF and up propagation news from G3YLA and G4BAO
The main theme of the VHF and up propagation options is that we have three distinct phases coming up.
The first phase is set to end today, the 21st. This will be the final blast of the cold northerly wind, which may produce some rain scatter near coasts from snow showers. It is probably not especially useful for Tropo, even inland, except perhaps for local overnight temporary short-distance enhancements due to surface cooling and night frosts.
Phase two is the transition to very unsettled, wet and windy weather, which starts to arrive during this weekend, ending the 21st, and generally sets the pattern for much of the coming week. Maybe it will be a rain scatter option for the GHz bands, but the main radio consideration will be wind potentially damaging antennas, particularly in the south.
Phase three will be the introduction of a weak ridge of high pressure over southern Britain in the second half of the coming week and the following weekend. This could bring some more productive Tropo to southern parts of the UK, especially into the last weekend of the month.
Other propagation modes are available but don’t seem to be elevated beyond chance occurrences for meteor scatter or aurora. There is a vanishingly small chance of Sporadic-E, as we are in the minimum period for this sort of propagation until after Easter.
For EME operators, Moon declination is positive and rising, reaching a maximum on the 23rd. Path losses increase all week until apogee on Monday the 29th. 144MHz sky noise is low to moderate this coming week.
And that’s all from the propagation team this week.

RSGB releases new video about changes to amateur radio licensing
WRTC 2026 team to appear in an RSGB Tonight@8 webinar
Paul Athersmith, M0PLA achieves Mountain Goat award
Following Ofcom’s consultation on the amateur radio licence last year, it released a statement in December 2023. The statement outlined its decision to update the amateur radio licensing framework to ensure the policies and licences meet the needs of today’s and tomorrow’s radio amateurs while streamlining the licensing process. It also published a General Notice, giving notice of its proposal to vary all amateur radio licences. The RSGB has just released a video in which RSGB General Manager Steve Thomas, M1ACB chats to RSGB Spectrum Forum Chair Murray Niman, G6JYB. Murray recaps some of the headline results of the Ofcom consultation, including where changes have occurred to Ofcom’s proposals. They also talk about what this could mean for radio amateurs in the future. This is a great example of how the RSGB is working not only to defend the spectrum but also to support all radio amateurs to understand and make use of the privileges they enjoy through their amateur radio licence. You can watch this video on the RSGB’s YouTube channel or via the Society’s licence review updates page at rsgb.org/licencereview

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of January 2024
We couldn't have asked for better solar conditions last week. We had a low Kp index that never got any higher than 2.67, and a solar flux index that started the week at 167 and then rose to 186 by Wednesday.
So, at first glance, this looks like ideal conditions for HF. However, we are in the middle of winter and therefore the ionosphere is not at its best. The low bands are also being affected by the higher solar flux and, on the whole, the 14MHz band and above are closing as the night draws in.
Daytime critical frequencies remain around 9 to 10MHz, so the 40m band should remain useful for inter-UK work. Nighttime critical frequencies are currently falling to 3.5 to 4.5MHz, which means the 40m band is only open to long skip, if at all.
The critical frequency is the highest that still returns a signal from the ionosphere if sent straight up, and is a good guide as to which bands are open to near vertical incidence skywave or NVIS signals around the UK.
On the brighter side, 14MHz has been showing signs of DX. The VK6RBP beacon has been heard on 14.100MHz in the afternoon via the short path and 28.200MHz in the morning via the long path.
The 12m band has shown international beacons RR90 in Siberia, OH2B in Finland, LU4AA in Argentina and YV5B in Venezuela, on 24.930MHz in the morning. While the 10m band also highlighted YV5B in Venezuela during mid-morning.
Not a massive catch, but better than we were getting two years ago!
For the coming week, NOAA predicts that the solar flux index may fall into the range of 150 to 165. Geomagnetic conditions are predicted to remain settled with a maximum Kp index of 2.
As always, this could easily change if we have a coronal mass ejection, so keep an eye on solarham.net for near real-time solar conditions.
And now the VHF and up propagation news from G3YLA and G4BAO
The area of high pressure has been working well for some parts of the country, with Tropo conditions lasting into the start of this weekend, but as a cold front moves South on Saturday the 13th, all will change as the high becomes displaced to the Atlantic.
Therefore, there is no significant Tropo for the coming week, but there may be some rain scatter from showers, especially around the coasts.
We seem to have passed the period of unusual winter Sporadic-E propagation without much evidence of activity so that just leaves meteor scatter. After the Quadrantids last week, we entered a period of low meteor shower activity, leaving just random meteors until the next major shower, the Lyrids in April.
For random meteor scatter, the pre-dawn period works best. The solar conditions can still be instrumental in producing extra propagation treats with chance aurora. Probably the best operating policy is to monitor the geomagnetic Kp-index with high values greater than 6 being a good sign for VHF.
For EME operators, this week starts with very low Moon declination, low peak Moon elevation and short Moon windows, but declination is rising and goes positive again on Tuesday. Path losses are still low and reached minimum at perigee on Saturday the 13th. 144MHz sky noise is low for all of the coming week.
And that’s all from the propagation team this week.

RSGB Regional Team vacancies
RSGB volunteer interviewed by the BBC
RSGB National Radio Centre seeks to expand its team of volunteers
The news team and all the staff at RSGB HQ would like to wish our newsreaders, listeners and online readers a very happy New Year. We would like to remind everyone that we always welcome your news, by email, to radcom@rsgb.org.uk and the deadline is 10 am sharp on Thursday mornings. The GB2RS script is usually uploaded to the RSGB website by 4.30 pm each Friday afternoon.
Are you interested in supporting your local radio amateurs and promoting amateur radio where you live? The RSGB Regional Team has eight Regional Representative vacancies across the UK where you could make a difference. Last year, Regional Reps got involved in a variety of activities including British Science Week and YOTA Month to help spread the word about amateur radio in their regions. If you have the passion to do this, go to the RSGB website at rsgb.org/election to find out how to apply. The deadline for applications is the 31st of January.
It was great to hear RSGB volunteer Peter Marcham, G3YXZ on BBC Radio Oxford on New Year's Day. Peter volunteers at the RSGB National Radio Centre, as well as being a tour guide at Bletchley Park. He spoke to radio presenter Sophie Law about his volunteering after sending the words "Bletchley Park Guide" to a three-word, text-in feature on why listeners were up early on New Year's Day. Search for Sophie Law on BBC Sounds, choose the New Year’s Day programme and listen from 2 hours, 11 minutes, and 25 seconds.
There is so much happening at the RSGB National Radio Centre that it needs to expand its team of volunteers! If you can volunteer on a Friday or Saturday, you will be particularly welcome. The NRC has a fabulous set-up, and full training on using the GB3RS radio station will be given. You should enjoy meeting people and be able to volunteer for one or two days per month as part of a friendly and dedicated team. NRC volunteers also enjoy numerous benefits associated with volunteering at Bletchley Park. For more information, please email NRC Coordinator Martyn Baker, G0GMB via nrc.support@rsgb.org.uk
We have received the sad news that both Mick Senior, G4EFO and Martyn Vincent, G3UKV have become Silent Keys recently. Mick was a former Regional Representative for Region 10, and the keeper of a number of local repeaters. Martyn was the District Representative for Shropshire, North Worcestershire and West Birmingham. Previously, he volunteered for the RSGB as the Regional Representative for Region 5 and as a member of the Nominations Committee. He was also a very well-respected member of the microwave and contesting communities. Our thoughts are with their families at this difficult time.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 4th of January 2024
Welcome to the first HF propagation report of 2024 – it looks like it will be business as usual!
A massive X5-class solar flare occurred on the 31st of December. Luckily, this happened at 2155UTC so didn’t affect the ionosphere over the UK. But it did launch a large coronal mass ejection, which was forecast to possibly hit the Earth on the 2nd of January. It looks like it largely missed us, although low-energy proton levels streaming past Earth continued to rise and were at the minor S1 radiation storm threshold on Wednesday the 3rd.
Had active region 3536 been directly facing Earth when the flare was observed, a stronger proton event and geomagnetic storm would have been very likely. Only minor HF signal degradation through the polar zones should be expected because of the minor S1 storm. So, it looks like we dodged the bullet again, but this is a warning that there could be more to come.
Otherwise, the solar flux index declined to the 140s over the Christmas period, although it looks like it may increase over the coming week.
NOAA predicts it could be in the range of 150 to 160 next week, with a maximum Kp index of 3 on Monday the 8th, or Tuesday the 9th. However, this could soon change if we have another solar flare and subsequent coronal mass ejection, which could see the Kp index rise two days later. So, make the most of HF when the Kp index is low!
Otherwise, the winter period is when the low bands, from 160 to 40m, come into their own. While solar maximum is not the best time for low-band propagation, there will still be plenty of DX to be worked. Generally speaking, winter is a good time for east-west paths on HF too.
Taking a closer look at 40 metres, the band should open for DX in an easterly direction during the late afternoon and towards the south at sunset. Paths during the afternoon may also include West Coast USA in mid-winter. Relatively local contacts should be possible during the day, as the critical frequency remains above 7MHz during daylight.
And now the VHF and up propagation news from G3YLA and G4BAO
A new year brings a change of weather type and, after some residual rainfall events at the tail end of the previous week, we should be seeing a marked improvement in the weather as high-pressure returns fairly generally across the country by this first weekend of January, ending today, the 7th.
This will remain near, or very close by, for much of the coming week and into the following weekend. It is good news for Tropo, initially over the North Sea towards southern Scandinavia and the Baltic region, but will probably change to favour the western side of Britain in the second half of the week. This is nice timing to coincide with the 70cm band RSGB contests during the week on Tuesday the 9th and Wednesday the 10th of January.
Up until the middle of the month, we should be alert to rare mid-winter sporadic-E propagation. With a very contorted jet stream pattern during the whole period, the chances are better than average. This is another piece of good timing for the 50MHz UK Activity Contest on Thursday the 11th.
We were going through the Quadrantids meteor shower as this report was being written, so this may provide a little boost to meteor scatter into some of the coming week. Rain scatter will be a rapidly diminishing option during the period as high pressure builds next week. The solar conditions continue to produce elevated Kp index events. So, again, check for auroral openings although, generally, aurora is usually better towards the Spring.
For EME, this week we see a negative Moon declination, falling to a minimum by Wednesday. So, Moon windows will be short and peak Moon elevation will be low. Path losses are also low, but we are still over a week away from perigee, the closest approach of the Moon to the Earth. 144MHz sky noise increases all week culminating in the Sun and Moon being close in the sky on the 11th.
And that’s all from the propagation team this week.

The news headlines:
Examinations and Syllabus Review Group to update syllabus
The RSGB election process is underway
Volunteer Youth Country Representatives sought
Season’s greetings to all our listeners! Today’s GB2RS news script will be the final one of 2023. Today’s news reading is optional, as the RSGB appreciates that not all newsreaders will be available, but the script will be on the RGSB website so all can see it. We’d like to take this opportunity to thank all the newsreaders, who read the news on a variety of platforms, for their service to their fellow amateurs throughout the year. We’d also like to remind amateurs that there has been a long-standing convention to listen for news broadcasts on Sundays before transmitting, to allow news reading to go ahead without interference. Thank you to all those who listen on Sunday mornings, and the other times that the news is read, to those who call in afterwards to speak to the newsreaders, and to everyone who listens via various platforms. Please note, there will be no script prepared for broadcast on Sunday the 31st of December 2023 due to RSGB HQ being closed from 4.30 pm on Friday the 22nd of December until 8.30 am on Tuesday the 2nd of January 2024. Newsreaders may, of course, choose to run a net at their normal transmission time, but under their own callsign only.
Following its consultation on proposed changes to the amateur radio licence, Ofcom has recently published the “General notice of proposal to vary amateur radio licences”. The timescale for putting the licence changes into effect means that the Examinations and Syllabus Review Group has been working on the revised syllabus, version 1.6, in parallel with the Ofcom consultation. To read the full explanation, and see the draft sections, go to the RSGB website at rsgb.org/training and choose the ‘Trainer Information’ link in the righthand menu.
The RSGB election process is underway and the closing date for RSGB Nominated Directors is Wednesday the 3rd of January. In being a Director, you are responsible for taking strategic decisions that steer the direction of the Society and provide leadership and motivation to implement its strategy. If you have the right skills and attributes that you think can help the Society develop for the future, then please get in touch. Contact the Nominations Committee Chair, Bob Beebe, GU4YOX via nomimations.chair@rsgb.org.uk On the RSGB website there is information about the Elected Director and Regional Representative roles available and the process for standing for those roles. You can also read an important statement from Don Beattie G3BJ, former RSGB President and IARU Region 1 Past-President, in which he outlines what he thinks are the necessary skills for Board Directors and encourages people to play their part in the future of the Society. Go to the RSGB website at rsgb.org/election to find out more.
A reminder now that the RSGB is looking for four licensed radio amateurs to help raise the profile of wireless communication amongst young people. Initially, we’re looking for RSGB members based in England, Northern Ireland, Scotland and Wales to engage young people in the hobby. These volunteer Youth Country Representatives will represent the RSGB at externally organised events and will plan and deliver outreach activities. If you have plenty of ideas, a passion for getting young people involved in amateur radio and experience of running small-scale events, we would be very keen to hear from you. For full details of these roles, see rsgb.org/volunteers and for an informal discussion, please email RSGB Board Director, Ben Lloyd, GW4BML at: gw4bml@rsgb.org.uk
If you live in Region 11 you could support your local amateur radio community by becoming an RSGB District Representative. DR111 covers Cornwall and the Scillies, whilst DR114 focuses on Dorset. If you would like to find out more, please contact the Region 11 Regional Representative, Andrew Jenner, G7KNA. There are also District Representative vacancies in Region 3 and Region 10 – find out more on the RSGB website at rsgb.org/volunteers

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 21st of December 2023
We filed last week’s GB2RS propagation report and, shortly after, we had the biggest X-ray solar flare event this cycle!
This just shows how hard it is to predict solar activity and why long-term HF predictions are problematic. Anyway, back to the solar flare which occurred at 1702UTC on the 14th of December. This was an X2.8 event that was also responsible for a coronal mass ejection.
Luckily, the Sun had already set in the UK but if you were working the USA, Caribbean or South America on HF, you may have found the path suddenly disrupted. If that did happen to you, please let us know.
The full halo coronal mass ejection, or CME, that followed headed mostly to the west, although a glancing blow was predicted to hit us on the 15th or 16th of December. It eventually hit late on the 17th of December, pushing the Kp index to six on the morning of the 18th of December. HF conditions remained fairly unsettled after that.
Next week, NOAA predicts that the solar flux index will be in the 140 to 150 range again and that the Kp index will be no more than two. However, that geomagnetic prediction may be wishful thinking. There are a lot of sunspots at the moment and active region 3529 may be a strong candidate for flare and CME action over the coming week.
So, our message is: work the DX when you can and don’t ignore the lower bands, such as 40, 80 and 160 metres, which may offer some good DX at night in the middle of winter.
And now the VHF and up propagation news from G3YLA and G4BAO
The weather pattern over the Christmas period is set up as a teaser between very mild, and cold enough for some wintry weather. However, it probably won’t be cold enough – except in the north – to get too excited before the 25th.
To set the scene and give you a chance to ‘roll your own forecasts’ in view of the long lead time for this forecast, the atmosphere is part way through its normal transition from summer-time Atlantic jet streams over Iceland to winter jet streams over the Mediterranean.
We are currently in the middle, and this puts the main jet stream path across the British Isles. It will produce alternating periods of mild and cold weather – very difficult to pin down even a few days ahead, let alone into the New Year!
What we can get from this, in terms of propagation, is a good chance of the meandering jet stream being able to invoke a mid-winter Sporadic-E event for some of us. However, the times are less predictable than in the summer, so just keep a listen out on the 10m and 6m bands for activity, it would be a shame to miss any.
Tropo has done well over the last weekend, so a large high to the south of the UK, over the continent, is worth looking out for especially paths south to Iberia or east to the Baltic.
Lastly, look out for the lesser modes of scatter from rain or meteors, which will continue to be a random option, as well as the potential for aurora.
For EME operators, Moon declination is positive and rising, reaching a maximum on Boxing Day. Path losses are rising to a maximum on New Year’s Day. 144MHz sky noise is moderate all week.
Finally, a big thank you from the propagation team for the 'fine business' effort you all put into getting on the bands to explore and report these exciting propagation modes… Merry Christmas!
And that’s all from the propagation team this week.

Youngsters on the Air month is well underway with some great activity from a range of schools, universities and radio societies. If you’d like to get involved, you can listen out for special callsign GB23YOTA and make these young operators feel welcome on the air. Today, the callsign is being operated between 9 am and 6 pm under the supervision of RSGB Board Director, Ben Lloyd, GW4BML. Young members of the Hereford Amateur Radio Society, and other local youngsters, will be getting on the air. Later this week, on Thursday the 21st of December between 6 pm and midnight, Ben will also be helping a fully licensed young radio amateur activate a SOTA summit. They will be working the 160m and 80m bands with the YOTA callsign. On Saturday the 23rd of December, Tommy M7OMY, supervised by M0BOY, will be back on the air for the duration of the day and night. There is still time to get involved with Youngsters on the Air month – just email Jamie, M0SDV at yota.month@rsgb.org.uk to book a slot or ask for further information.
Following four weeks of deliberations, the 2023 World Radiocommunication Conference concluded in Dubai on Friday the 15th of December with the signing of the ‘Provisional Final Acts’ and a closing ceremony. The numerous changes don’t formally take effect until the 1st of January 2025 and preparations are already underway to agree the agenda for future WRC events. The RSGB’s special focus pages have the final news report and photos. To view these, visit rsgb.org/wrc-23 The results will be reviewed by the Spectrum Forum after the Christmas break, alongside IARU and domestic changes.
The UK Meteor Beacon project is now in its second phase, and both phases have been supported by the RSGB Legacy Fund. At the RSGB 2023 Convention, Brian Coleman, G4NNS outlined the plan for the second phase. A network of receivers will be developed, streaming their data via a central server for detailed study of individual meteor events. This is a cooperation between the ‘worlds’ of amateur radio and astronomy. You can now watch Brian’s presentation on the RSGB YouTube channel at youtube.com/theRSGB The RSGB Legacy Fund supports a wide range of amateur radio projects. You can find out more and download an application form on the RSGB website at rsgb.org/legacy
The RSGB election process has begun and there are eleven roles to fill. These include eight Regional Representatives covering a wide range of regions, as well as an elected Director and two Nominated Directors. Bob Beebe, GU4YOX is the new Chair of the Nominations Committee and he is keen to see people volunteer. He says that being a Director of the RSGB is a great opportunity to contribute to the future direction of the Society and the RSGB needs the best people to come forward to play their part. If you don’t feel you can volunteer, do you know someone who would make a good Director? Do you know someone committed to amateur radio, in touch with the leading thinking in amateur radio today, and capable of contributing to the Society’s work in a team environment? If so, ask them to stand for election or as a Nominated Director. Find out more about the RSGB election process, and all the available roles, on the RSGB website at rsgb.org/election
Following feedback from the amateur radio community, the RSGB’s Learning Team is launching a revised Discovery Scheme in the New Year. This will be a revamp of the Individual Scheme from the Beyond Exams initiative and consists of three levels of participation. The ‘Explorer’ level is aimed at newcomers to amateur radio and will run from January to March 2024. The ‘Adventurer’ level, which will run from April to June 2024, is targeted at those who have been involved with amateur radio for a while and wish to progress. Requiring more significant experience, the ‘Master’ level will run from July to December 2024. For more information, contact Beyond Exams Coordinator Mark Burrows, 2E0SBM via be.coordinator@rsgb.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of December 2023
We had a fairly settled time last week with only the solar wind and some solar flare activity to contend with.
Sunspot region 3514 produced a moderately strong M5.8 solar flare on the 14th of December. This event was responsible for a coronal mass ejection, or CME, but that was directed to the west and missed the Earth.
The problem with the solar wind is that its Bz has mostly been pointing south, which means it more easily couples with the Earth’s magnetic field allowing solar plasma to flood in. The result was that the Kp index mostly remained high, with the index hitting three or four across the midweek period.
While not excessive, this has affected HF to an extent, although the daytime MUF over 3,000km has remained above 28MHz on most days.
What you may find is that the higher bands are now closed until later in the morning and that they close earlier in the afternoon as well. This is partly due to the time of year and partly due to the lower solar flux index we are experiencing.
The solar flux index improved slightly over the past week, ending at 135 on Thursday, having been in the 120s earlier.
Next week NOAA predicts that the solar flux index will be in the range of 125 to 140. It is predicting unsettled geomagnetic conditions from the 16th to the 19th of December, with a maximum Kp index of five.
Now for a propagation forecast. Santa’s broadcasting arm, Santa Radio OF9X, is active again from near the Arctic Circle on all amateur radio bands, using CW, SSB and FT8, until the end of the year. The activity is organised by the Radio Club of Pusula, OH9W and Radio Arcala, OH8X.
Keep an eye on DXSummit.fi to find out where they are operating. So far, they have been spotted on the 160, 40, 20, 12 and 10m bands. The Proppy prediction chart shows that anywhere between 10MHz and 28MHz is fair game during daylight, while 7MHz and below will work better at night.
And now the VHF and up propagation news from G3YLA and G4BAO
As expected, the return of a significant region of high pressure developing over the continent as this week ends will bring some enhanced Tropo conditions from the southern UK into the continent and across Biscay to northern Spain.
It is also possible that the traditionally preferred policy of beaming around the edge of a high for DX paths will make looking east into northern Germany, Poland and the Baltic a fair prospect, but only until around Tuesday the 19th when a cold front moves south and breaks the path. This is a pity since it will be before Tuesday’s 1.3GHz Contest and Thursday’s 70MHz UK Activity Contest, which look like missing the best conditions.
The second half of the coming week will be dominated by low pressure to the north of Britain and a series of fronts and showery troughs driving south, bringing much colder air with a risk of wintry weather. It will also become very windy at times.
This removes Tropo from the picture, but rain scatter may be worth considering, although the shower echo regions will be moving briskly. Use online rain radar displays to help you.
The other modes of meteor scatter and aurora are worth leaving on the list with the remains of the December Geminids still with us.
Don’t forget that out-of-season Sporadic-E propagation often appears in the period from mid-December to mid-January, so check the 10 and 6m bands periodically for activity.
For EME operators, Moon declination is negative but rising, going positive on Wednesday the 20th. Path losses are at a minimum at perigee, the Moon’s closest point – this was on Saturday the 16th. 144MHz sky noise is low all week.
And that’s all from the propagation team this week.

23cm recommendation approved at WRC-23
RSGB Examinations Standards Committee report published
RSGB Elections process begins
The third week of the WRC-23 World Radiocommunication Conference has seen the approval of a new footnote to the 23cm amateur band at 1240 to 1300MHz under Agenda Item 9.1-b. This draws attention to the recently released ITU-R Recommendation 2164 that provides guidance to avoid interference to radio navigation satellite services, or RNSS, such as Galileo. This is a major landmark after four years of hard work which started after WRC-19 and now lays out the basis for guidance and next steps. IARU President Tim Ellam, VE6SH said that the addition of a footnote that provides guidance to administrations in the event of interference to the RNSS is a good regulatory outcome for amateurs and the primary users of this band. You can read more on this story at tinyurl.com/RecRNSS The IARU team continues its work on other WRC issues including the development of agendas for future conferences. The RSGB special focus page provides regular updates and additional detail. You can find the page at

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 7th of December 2023
We dodged a bullet last week as a high-speed solar wind stream from a coronal hole sped past the Earth. Although the wind speed was often in excess of 600 kilometres per second, its Bz, or magnetic field, was pointing north. The net result was that most of this passed harmlessly away from Earth and the Kp index remained around three.
Meanwhile, the solar flux index declined to 130 by Thursday, which is quite a difference from the 194 we had on the 23rd of November.
Solar activity last week reached moderate levels thanks to multiple low-level M-class solar flares detected around active region 3513 in the northeast quadrant. This region also produced frequent C-class flares.
Daytime MUFs over a 3,000km path mostly remained over 28MHz, while nighttime MUFs over a similar path length remained around 10MHz.
As we head towards mid-winter, we may expect these nighttime MUFs to drop, with the result that the 80m band closes down for short-skip early on in the evening – the curse of the inter-UK 80m Club Championship contests!
However, the 80m band may still be open over long distances and we are now entering the best time of year for low-band DXing. Keep an eye on the top end of the 80m band, around sunrise, for transatlantic signals.
Next week NOAA predicts that the solar flux index may recover a little and be in the range of 130 to 150. Geomagnetic conditions will depend upon coronal mass ejections but are predicted to be good, with a peak of Kp4 on the 12th of November. There is a slender coronal hole on the Sun that could cause the Kp index to rise this weekend, ending the 10th, due to its associated solar wind stream. However, it shouldn’t be too bad and any poor HF conditions are likely to be short-lived.
Finally, NOAA has updated its progression forecast for Solar Cycle 25. It now predicts that this cycle will peak somewhere between January and September 2024 with a solar flux index of around 167 to 201.
And now the VHF and up propagation news from G3YLA and G4BAO
The present spell of unsettled weather at the end of the first week of December will run into the first half of next week.
This brings a limited chance of rain scatter on the GHz bands, but there is a strong signal in the models for a major change of weather patterns for the middle of next week.
This will be the arrival of high pressure around Wednesday the 13th that will probably last into the following weekend, although there is some model variation in how quickly it will move away.
The main result is that, although it begins as a cold air with high pressure with frosts, it will probably develop surface temperature inversions, which will be useful for Tropo. Towards the end of next week, as the centre of the high drifts east, it will allow more moist air at the surface and produce stronger ducting potential as well as develop an upper-level inversion for longer DX paths into the continent.
The evening of the 14th of December sees the peak of the biggest and most reliable meteor shower of the year. The Geminids have the potential for a zenithal hourly rate of 150. The higher 50MHz and 144MHz activity usually provide the best chances, and a reasonably quiet QTH with 100W and a beam will bring you plenty of digimode QSOs.
QSOs are even made by EME-class stations on the 70cm band and strong, long reflections on the lower bands can allow SSB QSOs if you’re persistent enough.
That said, MSK144 and FSK441 digimodes will be the most reliable.
Aurora remains a possibility, but the isolated out-of-season sporadic-E blips on the Propquest NVIS plots last month have quietened down for now.
For EME operators, Moon declination is negative, falling further and reaching its minimum on Thursday the 14th. Path losses are falling towards a minimum at perigee on Saturday the 16th. 144MHz sky noise is moderate until the 12th and 13th when the Moon and Sun are close in the sky.
And that’s all from the propagation team this week.

The RSGB Emerging Technology Coordination Committee members will be taking a break from processing Notices of Variation and enquiries from the 20th of December until the 3rd of January. They will reply to emails after that but please be patient as they work through any backlog.
When G-QRP Club Secretary Dick, G0BPS, heard about the Radio Communications Foundation initiative to pay for 60 RSGB Foundation exams taken by young people in full-time education, he asked if the Club could help out. The Club Committee, minus Chairman Steve G0FUW, who is also an RCF Trustee, agreed to sponsor an additional ten exams. The RCF now has the funds and awaits applications from young people who would benefit from a little help in getting started in amateur radio. The G-QRP Club is devoted to low-power communications and has over 4,000 members, mostly in the UK, but also in pretty much every corner of the world. Further information can be found at gqrp.com

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 30th of November 2023
We were lucky last week – the solar flux index remained quite high and, after the geomagnetic upsets around the 25th, we had settled conditions, with the Kp index below two.
Unfortunately, it looks like that is all about to change.
On Tuesday the 28th, two M-class solar flares and associated coronal mass ejections caused a plasma cloud to be directed towards Earth. It is expected to catch up with an earlier coronal mass ejection, or perhaps arrive shortly thereafter.
Moderate G2 storming with a chance for strong G3 storming can therefore be expected, with an increased Kp index.
If this wasn’t bad enough, a very large coronal hole is rotating into an Earth-facing position as well.
This became geo-effective on the 2nd of December, and we can therefore expect any associated plasma in the solar wind early next week. Just how bad it will be is hard to say as it will largely depend on the interplanetary magnetic field of the plasma coming off the Sun. If it's north-facing we might just dodge the bullet but, if it is south-facing, we can expect significant auroral displays and propagation to match.
Either way, it will be worth keeping an eye on solarham.net and also the upper HF bands for signs of auroral-type activity. After an initial surge in the MUF, we can expect band conditions to decline for at least a day or two.
So, all in all, then, we can expect the bands to be disrupted at the end of this weekend ending the 3rd of December.
Next week NOAA predicts the worst will be over by the 8th of December, but we are in uncharted territory and can expect anything to happen. So, work the HF DX if and when you hear it!
On a side note, we are now heading towards winter propagation conditions so expect to hear DX activity on Top Band and 80m at night and especially around sunrise. The 40m band may also throw up some surprises during late afternoon.
And now the VHF and up propagation news
The weak but cold easterly pattern is providing some sharp frosts, and scattered showers suggest that Tropo is not likely. However, the overnight cooling temperature inversion inland, or anywhere away from the East Coast, could see temporary Tropo develop overnight and up to about mid-morning. The showers themselves are mostly fairly shallow and don’t look wonderful from a rain scatter perspective.
All of this changes by mid-week as low pressure starts to dominate again and really takes control for the rest of the coming week. This will bring stronger winds, spells of heavy rain and a return to milder air again. It does not, however, encourage thoughts of Tropo becoming a big player next week!
Don’t forget to check in the early mornings for random meteor scatter opportunities and keep an eye on the Kp index for possible aurora. This is the better option with such an active Sun at the moment and, as we said earlier in the HF report, seems to be a strong player as we finish this first weekend of December.
For EME operators, Moon declination is positive and falling, going negative on Thursday the 7th. Monday the 4th is apogee when the Moon is furthest away so expect path losses to be at their highest. 144MHz sky noise is low all week.
And that’s all from the propagation team this week.
