GB2RS NEWS Sunday 18th November 2018 The news headlines: • First geostationary amateur satellite success • New RSGB Convention videos on YouTube • New version of WSJT-X On Thursday the 15th of November, a SpaceX Falcon 9 vehicle lifted off flawlessly at 2046UTC from Cape Canaveral. It was carrying the first amateur radio payload destined for geostationary orbit. About 32 minutes after launch, SpaceX reports the spacecraft was successfully deployed into a geostationary transfer orbit. Positioned at 25.5°E, the satellite will carry an amateur radio S-band and X-band payload capable of linking radio amateurs from Brazil to Thailand. The recent subject of an AMSAT-UK Colloquium presentation, Es’hail-2 carries two Phase 4 non-inverting amateur radio transponders operating in a 2.4GHz up and 10.45GHz down configuration. This offers a 250kHz bandwidth linear transponder intended for conventional analogue operations, plus an 8MHz bandwidth transponder for experimental digital modulation schemes and DVB amateur television. You can see the talk at www.youtube.com/user/AMSATUK/videos Two more 2018 RSGB Convention talks are now on YouTube. Using drones to measure antenna radiation patterns by Jenny Bailey, G0VQH looks at how antenna radiation patterns are difficult to measure because antennas are typically high above the ground. A practical method of measuring the radiation field around an antenna could be with a drone. This video deals with the CAA restrictions, drone selection, payload and operation as well as measurement antenna design and plotting the results. The second video is An Introduction to SDRs and GNU Radio by Heather Lomond, M0HMO. She gives an overview of what is in an software defined radio, the types of tasks they can do for us and how to get started with them, as well as an introduction to some digital signal processing techniques such as IQ Modulation, Filters, DDS and FFT demodulation. Go to rsgb.org/videos, click on the RSGB Convention lectures section and then the RSGB 2018 Convention icon to view these videos. A new WSJT-X release candidate, version 2.0.0-rc4, now is available, and the version 2.0 Quick Start Guide has been revised and extended. The developers urge anyone upgrading to the new version to read the release notes thoroughly. The upgrade requires users to change operator settings, so the software may not work straight out of the box when upgrading from previous versions. The latest version of WSJT-X also removes compatibility with earlier versions of the software in certain circumstances. Full information is at https://sourceforge.net/p/wsjt/mailman/message/36465968/ It is vital that we contribute to the debate around spectrum use. Former RSGB Chairman Graham Murchie, G4FSG recently made a presentation on behalf of all UK radio amateurs to the UK Spectrum Policy Forum, a body that advises the government. He also led the subsequent discussion, supported by RSGB General Manager Steve Thomas, M1ACB and RSGB Spectrum Forum Chair Murray Niman, G6JYB. Topics included the shortage of practical skills in the radio arena, the social and economic aspects of spectrum use, and examples of where the RSGB is encouraging development of scarce skills and using them to good effect. You can see the presentations at tinyurl.com/GB2RS-1811A Lithuania and Montenegro are the latest countries active on 60m. Lithuania’s telecomms regulator has enabled the new WRC-15 Secondary Allocation of 5351.5 – 5366.5kHz at 15W EIRP in its 2018 update to the country’s Frequency Allocation Table. The latest update to the Montenegro National Frequency Plan lists a new band at 5MHz, namely the WRC-15 Amateur Secondary Allocation of 5351.5 – 5366.5kHz with 15W EIRP, which has been confirmed by national society, the Montenegro Amateur Radio Pool. As from this Sunday, the 18th, at 1830UTC, Eddie, G0VVT will be reading GB2RS News on GB7ST slot 2 talk group 9, the DMR repeater in Stoke on Trent. At the same time, he will read the news on 433.525MHz and GB3SX, the 6m repeater in Stoke on Trent. Thanks go to Eddie and all the other news readers who give freely of their time to serve their fellow radio amateurs. The RSGB has appointed Sara McGarvey, 2I0SSW into the new role of Youth Committee Champion. The role will include managing the UK attendance at the YOTA camp each year and YOTA Month every December. The next Advanced Distance Learning course to be run by the Bath-based team is due to start on the first of February 2019, aiming for an exam in July or August. Course places are limited; the last four were completely filled well before the start date. So, if you are interested in joining, contact the Course Leader Steve, G0FUW, without delay, via email to g0fuw@tiscali.co.uk. Now a date for next year’s diary. The RSGB AGM will be held on 27 April 2019 at Jurys Inn, 245 Broad Street, Birmingham B1 2HQ. The Society’s accounts and reports for 2018 will appear in the April 2019 RadCom. Three of ITU-R Study Group 5 Working Groups meet in Geneva between the 5th and the 16th of November. Working Party 5A deals with the Land mobile service above 30MHz, wireless access in the fixed service and the amateur and amateur-satellite services. Working Group 5A1, responsible for amateur matters is chaired by Dale, VK1DSH. The main topic is to develop a technical report to support the work for World Radiocommunication Conference 2019 Agenda Item 1.1, considering an allocation of the frequency band 50 to 54MHz to the amateur service in Region 1. The Working Group consists of a mix of radio amateurs from all three IARU Regions, administrations from all over the world and other interested parties like meteorologists and military. -- And now for the details of rallies and events for the coming week The Nevada Radio and Waters & Stanton Open Day takes place today, the 18th.

Please send event details to radcom@rsgb.org.uk, as early as possible, for free publicity on GB2RS, in RadCom and online. UK special event stations must be open to the public, so our free publicity can help make your efforts more widely known. -- Now the contest news Today, the 18th, the UK Microwave Group’s Low Band contest runs from 1000 to 1400UTC. Using all modes on the 1.3 to 3.4GHz bands the exchange is signal report, serial number and locator. On Tuesday the 1.3GHz UK Activity Contest runs from 2000UTC to 2230UTC. Using all modes the exchange is signal report, serial number and locator. On Wednesday the Autumn Series contest runs from 2000UTC to 2130UTC. This is the SSB leg and is on the 80m band. The exchange is signal report and serial number. The big contest this month is the CQ Worldwide DX CW Contest over the 24th and 25th. Conditions are unlikely to be good, but at least CW is a narrowband mode so really weak signals should be more copyable than on other modes. It starts at 0000UTC on the 24th and runs until 2359UTC on the 25th. Using all contest bands from 1.8 to 28MHz, the exchange is signal report and CQ Zone, which for the UK is 14. -- Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 16th of November. The predicted bad geomagnetic conditions forecast for last weekend didn’t turn out to be quite so bad after all. The Kp index only rose to four on the tenth and then conditions settled again, despite a large coronal hole on the Sun’s surface. However, reports did come in of poor conditions on 80 metres on Monday evening during the RSGB 80m Autumn Series contest. A good guide to conditions for inter-G, or near vertical incidence skywave propagation, is always the ionosonde data at propquest.co.uk. The site showed that the critical frequency, which is the maximum frequency at which signals launched vertically into the ionosphere are returned, dropped as low as 3.16MHz on Monday evening. This so-called critical frequency, or FoF2, meant the ionosphere couldn’t support close-in 80 metre signals – they basically carried on out into space rather than being returned to Earth. This may be a trend we see in the evenings throughout the winter, especially with a solar flux index as low as 67 as we have been seeing. The only answer is to move to Top Band or make do with VHF and UHF. Next week, NOAA predicts more of the same, with an SFI of around 68-70. Geomagnetic conditions are predicted to be more settled though with a maximum Kp index of two. This means daytime maximum useable frequencies are likely to be around 18 or 19MHz over a 3,000km path. There have been the occasional openings during the day up to 21 and even 28MHz, but these are likely to be fleeting and generally unreliable. Night-time MUFs over a 3,000km path may struggle to reach 9-12MHz at times, with 40, or more likely 80 metres, being the highest reliable band for DX. -- And now the VHF and up propagation news. It looks like a good Tropo spell coming up, especially over the eastern side of the country with some good paths across the North Sea to northern Europe and Scandinavia. This is due to a strong temperature inversion set up by a large area of high pressure over Scandinavia. As this high drifts away towards Iceland, the Tropo will decline and low pressure will take over for southern areas by mid-week. This could introduce some coastal showers, especially along the English Channel and over the southern North Sea, which may bring some chance of rain scatter for the microwave bands. Today we should still be in the tail end of last night’s Leonid meteor shower so look for enhanced meteor scatter paths. Moon declination goes positive tomorrow so the week will see increasingly long Moon windows and path losses will fall as the week progresses. And that’s all from the propagation team this week.

Did you see the cool CGI videos of the Falcon rockets landing upright? Everything about it violates all we know about aeronautics. That's why they had to do CGI videos. Your tax dollars hard at work.
