The news headlines:

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.

The RSGB Examinations Standards Committee has published its annual report, covering the operation of the amateur radio exams during the calendar year of 2022. You can read the report on the RSGB website. Go to rsgb.org/esc and click on Minutes, Papers and Reports in the righthand list.

If you are keen to see amateur radio, and the RSGB, continue to thrive over the coming years, this is the time to volunteer for an RSGB Board or Regional Team role. This year the Society is looking for one elected Board Director, two Nominated Board Directors and eight Regional Representatives. You can find candidate packs, forms and further details on the Society’s website at rsgb.org/election If you’re interested but unsure, please read the information set out on the elections web page first and then have an informal chat with the RSGB Company Secretary. Email Stephen Purser, GW4SHF at [email protected]

The RSGB Board is delighted to announce that Bob Beebe, GU4YOX has been appointed as the new Nominations Committee Chair. The Board would like to thank Stephen Purser, GW4SHF for his work in this role over a number of years, and it is pleased that he will continue in his other role as Company Secretary. You can find out more about the Nominations Committee on the RSGB website at rsgb.org/nomcom and you can email Bob via [email protected]

Don’t forget that the last of the RSGB’s Tonight@8 webinars for 2023 is at 8 pm tomorrow, Monday the 11th of December. It focuses on amateur radio construction and the RSGB Construction Competition. Jenny Curtis M7JNY, Colin Murray GM4EAU, and David Law G0LBK will talk about the projects they worked on and why they decided to submit them to the RSGB Construction Competition in recent years. Watch live on the RSGB YouTube channel or special BATC channel and ask questions via the live chat. To find out more go to the RSGB website at rsgb.org/webinars

EIRSAT-1 launched on a Space X Falcon 9 rocket from the Vandenberg Air Force Base in California, USA at 1819UTC on Friday the 1st of December 2023. 'EIRSAT-1' stands for 'Educational Irish Research Satellite'. A team of students at University College Dublin, with support from academic and professional staff, has designed, built, tested, and will operate, Ireland's first satellite, a 2U CubeSat. It has a downlink on the IARU coordinated frequency of 437.100MHz. For more information about the project visit eirsat1.ie

The UK Six Metre Group Winter Marathon is underway. The objective is to work as many four-digit grid squares as possible, between 0000UTC on the 1st of December 2023 and 2359UTC on the 31st of January 2024, on the 6m band. Logs can be submitted until 12 February 2024. For more information visit uksmg.org

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.
