GB2RS News
Sunday the 3rd of April 2022
The news headlines:
- Transatlantic tests and Paul Godley lecture
- Volunteers sought for the NRC
- MSF signals closed for maintenance
As most listeners will already know, Paul Godley was sent over from the USA 100 years ago to conduct the transatlantic tests. Those tests opened up the era of short-wave radio communication. But why Paul Godley? Who was he, why was he chosen and what happened next? On Thursday the 7th of April, all those questions will be answered in an open Zoom talk by Godley's grandson, Bruce Littlefield. The Zoom meeting will be hosted by Wigtownshire ARC in South West Scotland and will begin at 1900UTC. Everyone is invited, subject to a limit of 100, and joining details will be published closer to the meeting date at www.gm4riv.org.
The RSGB National Radio Centre welcomes thousands of people through its doors each month and introduces them to amateur radio. The Society needs to expand the team of volunteers and is particularly looking for people who can be part of the team each Thursday. If you are interested in becoming an NRC volunteer you should enjoy meeting people and be prepared to work a minimum of one, preferably two, days per month. Full training is given. Please email NRC Coordinator Martyn Baker, G0GMB for further information via nrc.support@rsgb.org.uk.
A scheduled annual maintenance shutdown of the MSF 60kHz Radio Time Signal service is planned. It will allow safe working on the masts and antennas. The service will be off-air from 0700 to 1700UTC each day between the 4th and 21st of April. The transmission will be restored overnight whenever possible. A radio-controlled clock will not be able to pick up the MSF signal during these periods, so may drift off from the correct time.
There have been recently a number of reports of individual holders of UK Amateur licences gaining Innovation and Trial licences from Ofcom. This is to conduct experimental transmissions on 40MHz or the 8m band. The RSGB has asked Ofcom for guidance concerning the status and possible contacts with such stations. Ofcom’s view is very clear. Any operation on 40MHz in the UK is not Amateur radio and therefore cross-band contacts to such stations by UK radio Amateurs operating on the bands licenced for amateur radio are not permitted. You can read the full statement from Ofcom in the RSGB Notices part of the RSGB website at rsgb.org.uk.
The RSGB is looking for a Convention Chair to lead the team of people who will create this year's Convention. If you understand the advantages of both online and in-person events and can contribute ideas for speakers and topics that will attract both audiences, this could be the role for you. For a full role description look on the volunteer vacancy page of the RSGB website at rsgb.org/volunteers.
BBC journalist and long-time RSGB Member Laurie Margolis, G3UML broke the fact of the invasion of the Falklands through amateur radio. On Monday the 4th of April, he will share how that happened in the RSGB’s free Tonight@8 webinar. He will also cover his involvement in the 1970 King Hussein story. Watch and ask questions live on the RSGB YouTube channel or special BATC stream. Find out more about this and the Society’s other webinars via rsgb.org/webinars
On the 18th of April, radio amateurs worldwide take to the airwaves in celebration of World Amateur Radio Day. It was on this day in 1925 that the International Amateur Radio Union was formed in Paris. You can read more about the event, download posters and other publicity material for any special event station you may be planning from iaru.org.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 1st of April 2022.
Last week we said there was a sense of excitement as it looked like the solar flux index would increase. But even NOAA didn’t predict that it would rise to 156, which it hit on Monday the 28th. Unfortunately, along with high sunspot numbers, we have had unsettled geomagnetic conditions. On Sunday and Monday last week, the Kp index hit four, due to the predicted coronal hole issues. By Thursday the 31st, the effects of an M4/M1 coronal mass ejection event from the 28th of March were being felt. This CME resulted from a pair of sunspots, which combined into one larger shock front.
The solar wind speed was above 500km/s and the Bz component of the interplanetary magnetic field shifted south meaning it coupled more easily with the Earth’s magnetic field, pushing the Kp index to five with warnings for middle to high latitude aurora happening.
If this wasn’t enough, we have had a number of solar flares to contend with, including an X1.3 event from active region AR 2975 peaking at 1737UTC on Wednesday the 30th of March. This will likely result in a CME coming our way.
All this has had numerous effects on HF, from fadeouts from the flares to pre-auroral enhancements from the CMEs and good conditions on 10 metres thanks to the high SFI.
A high f0F2 critical frequency has also meant that 40 metres has been open to inter-G signals at times.
We are now well and truly in a period where it is getting difficult to predict what will happen next. NOAA predicts that the SFI will remain above 120 for the next few days and then decline into the teens. We think the best advice is to keep an eye on solarham.net and watch out for news of CMEs leaving the Sun. Expect unsettled conditions around 48 hours after news of any CME.
But the best advice overall is just get on the bands and work DX whenever you can! We can often expect MUFs to exceed 28MHz at times so make the most of 10 metres when you can, for example, John, G4BAO reports 10m was wide open to Asia on Thursday morning.
And now the VHF and up propagation news.
Next week offers a change of wind direction from northerly to westerly with the glimmer of hope for high pressure after the weekend, but it's only a partial nod towards tropo with just a weak, temporary ridge extending across the southern UK from the Azores high.
The next items worth mentioning are as in last week’s bulletin; keep your ears and eyes open for aurora, after a promising end to the last week as we write this with fluttery signals on 80m, you should have sorted out some favourite beacons to listen out for. Also, the early mornings can be good for random meteor scatter activity.
As we roll over into April we are getting a bit closer to the 2022 Sporadic-E season. There have been some isolated examples on 10m CW/SSB and 6m on data modes, so it's time to start checking the position of jet streams and EPI on the Propquest.co.uk website.
The end of last week favoured paths to the south into Spain across a northwesterly jet stream over the Pyrenees and Cantabrian mountains, whereas next week it looks like paths to Scandinavia might be worth a look, although probably a lower probability for these more northern latitudes.
Moon declination is positive all week reaching maximum on Friday, so Moon windows and peak Moon elevation will be high. We are past perigee so path losses will increase throughout the week. 144MHz Sky noise is low all week, briefly hitting 500K on Thursday.
And that’s all from the propagation team this week.
