Bob says, "It is with a profound sense of respect and appreciation that today we mark the 70th anniversary of the GB2RS News service. Since 1955, volunteers have given their time, and their voice, to keep our radio community informed, connected, and inspired. For many of us, GB2RS has been a constant and familiar presence in our radio lives. On behalf of the RSGB, I extend my heartfelt thanks to all who have played a part in this remarkable story for the last seventy years. Today, we honour their legacy and reaffirm our commitment to the values and spirit that the GB2RS News service so proudly represents." And now we move to today's news items. The programme for this year's RSGB Convention has nearly 50 presentations for you to enjoy, including leading industry speakers such as Mike Walker, VA3MW from FlexRadio and Hans Summers, G0UPL from QRP labs. There will also be well-known names such as Neil Smith G4DBN, RadCom Technical Editor Peter Duffett-Smith GM3XJE, Brian Coleman G4NNS and Walt Hudson K4OGO, known to many as ‘Salty Walt'. This annual RSGB event is your only opportunity within the UK to have access to this level of knowledge, learning and networking opportunities. As well as a packed-full lecture programme, there will be nearly 20 special interest groups in attendance, so if you are thinking of pursuing a different area of the hobby, this is the perfect time to explore your options. To guarantee a place you will need to purchase a ticket online via rsgb.org/convention before advance sales close on Sunday the 5th of October. Buying your ticket online not only guarantees your place, but it also saves you money when compared to on-the-door ticket prices. If you are arriving on the Friday, why not join a private tour of Bletchley Park at 2.30pm, which has been arranged especially for Convention attendees. In addition to this, and new for this year, RSGB National Radio Centre volunteer Patrick, 2E0IFB will be running an informal introduction on getting started with low earth orbiting satellites. The RSGB Convention takes place from the 10th to the 12th of October at Kents Hill Conference Centre in Milton Keynes. The RSGB was pleased to welcome Callum Anderson, MP for Buckingham and Bletchley, to the RSGB National Radio Centre at Bletchley Park last week. Callum enjoyed seeing the history of radio, watching live CW contacts and listening to his voice coming back from space, having been relayed via a satellite. Callum was invited to meet a small group of senior RSGB representatives who emphasised the important role of amateur radio in encouraging young people into an engineering career. Getting involved in Science, Technology, Engineering and Maths activities gives a great foundation that could lead some young people to follow in the footsteps of radio amateur pioneers who led the development of many wireless technologies that we rely on today. Most importantly the visit gave the RSGB an opportunity to show the problems that ElectroMagnetic Disturbance can cause to wireless reception. Examples of EMD include household appliances, Broadband FTTC and green energy from solar panels and windfarms, where the signal levels are thousands of times stronger than the expected levels given in ITU recommendations. EMC Chair John Rogers M0JAV and Board Chair Stewart Bryant G3YSX explained that unless the year-on-year increases in background noise are stopped, many critical services and infrastructures could be impacted soon, just as the amateur radio bands are today. The RSGB looks forward to meeting again with Callum who is the Parliamentary Private Secretary for Science, Innovation and Technology. Don't forget to listen out for three special one-off broadcasts from the RSGB National Radio Centre today. The broadcasts are part of the celebrations which are taking place to mark the 70th anniversary of GB2RS. Listen out at 1pm, 2.30pm and 4pm. Go to rsgb.org/gb70rs for details of frequencies and newsreaders. All listeners are welcome to join the pre- and post-News nets, which will be operating using the special event station GB70RS. The RSGB LoRa high-altitude balloon launch took place on Saturday the 20th of September and was a great success despite tricky weather conditions, which included rain and high winds. The balloon soared at a peak altitude of 48,556 feet before landing in a remote location in the Thursden Valley. Winners of the competition to win a GBP 200 Moonraker voucher will be announced at the RSGB 2025 Convention on Sunday the 12th of October. If you're wondering what you can do with your LoRa tracker now the RSGB challenge has finished, go to rsgb.org/lora-balloon for a handy guide on how you can continue the fun.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 25th of September Last week was good for HF propagation for a number of reasons. Firstly, we are now entering autumn, which offers better propagation prospects than summer. Secondly, the solar flux index has remained high at up to 184 as of last Thursday the 25th. We had a week of near-normal geomagnetic conditions, with a low Kp index, no Earth-directed coronal mass ejections, and a relatively quiet solar wind. These have all combined to give excellent HF propagation, including openings on the 10m band using FM and transatlantic 10m contacts being possible in the afternoon. The maximum useable frequency, or MUF, over a 3,000km path, according to Propquest, has mainly been in excess of 30MHz during daylight hours. The KQ2H repeater in upstate New York, with an output frequency of 29.620MHz, has been loud at times in the afternoon and is a good indicator of HF propagation. Expect it to get better as we enter October. Other US stations have also been heard on the 10m band using FM, including one in Ohio. Steve, G0KYA was surprised to hear the GB3XMB 10m beacon on 28.287MHz from Waddington, Lancashire this week. Steve remarked that it is 175 miles to Norfolk as the crow flies. He said that the signal didn't sound like backscatter, so that's quite a distance for 10m ground wave. Other DX worked, according to CDXC, included FP5KE, the St. Pierre and Miquelon DXpedition. The station could heard on everything from Top Band to 10m. V6D in Micronesia has been worked on the 40 and 17m bands using CW. Other highlights include D2USU in Fiji on the 12m band using FT8, and 9Y49R in Trinidad and Tobago on the 10m band using FM. Next week, NOAA predicts the solar flux index may fall to be in the 159 to 170 range. Geomagnetic conditions are predicted to be poor tomorrow, the 29th, with a Kp index of 5, and again between the 3rd and 5th of October, also with a predicted Kp index of 5. Expect decreased MUFs for a few days until the ionosphere recovers. And now the VHF and up propagation news from G3YLA and G4BAO The next week or so looks to be typical for autumn. It will be a mix of Atlantic weather systems bringing lows and their fronts which may offer some rain scatter for those on the GHz bands. The other side of the coin is areas of high pressure or mostly weak ridges, in this case mainly affecting the south and east of the country. This is the point where Tropo operators can move in with paths probably favouring the North Sea and Scandinavia up to this weekend and then across to the continent and down to Spain during the coming week. It is worth remembering that Tropo can exist throughout the 24 hours across water and along coasts like the North Sea and English Channel, although the portion of a path overland can weaken during daytime. The meteor scatter prospects remain in the random territory, so are best in the early morning. Recent activity with geomagnetic disturbances suggests that aurora should continue to be part of the operating list in the coming week. Check for a hollow note or warble on HF signals and for a Kp index greater than 5, then consider turning your VHF arrays to the north. For EME operators, Moon declination reaches its minimum tomorrow, the 29th, so from then on we will see lengthening Moon windows and increasing peak elevation. The Moon's distance from Earth started to decrease after apogee on Friday the 26th, meaning path losses are falling. 144MHz Sky noise will be high today, the 28th, and peaks at around 2800 Kelvin tomorrow, the 29th, before dropping back to low for the rest of the week. And that's all from the propagation team this week. And that's the end of the main news for this week prepared by the Radio Society of Great Britain. Items for inclusion in subsequent bulletins can be emailed to radcom<at>rsgb.org.uk to arrive by 10:00 on the Thursday before transmission.
