Sunday 21st May 2017

The news headlines:

  • Brits join CQ Hall of Fame

  • Philip Willis joins RSGB Board

  • Licencing portal suffers glitch

Two Britons have been inducted into the prestigious CQ Magazine Hall of Fame this weekend. David Honess, M6DNT and Tim Peake, KG5BVI join 16 others entering the Hall, bringing the total to 310. David, M6DNT developed the AstroPi project, which sent two Raspberry Pi computers to the International Space Station as platforms for students on Earth to write and run their own computer code in space. British astronaut Tim, KG5BVI was very active in the ARISS programme whilst aboard the International Space Station, contacting numerous schools via amateur radio and operating the ISS end of the AstroPi project.

To bring the Board to full strength, the meeting on 13 May unanimously endorsed the co-option of Philip Willis, M0PHI as a Board Director. Philip has a wide range of experience, including chairing the Training and Education Committee.

The RSGB understands that there has been an issue with Ofcom’s online licencing system this week. At the time this bulletin was written the details and extent are unclear, but the problem appears to affect a number of new licensees, and those upgrading following a recent exam pass. Ofcom engineers are working to fix the system, and it is hoped that the online licensing portal will soon be fully operational again. An ongoing programme of upgrade and maintenance work is likely to lead to further, planned outages, which will be publicised as the details become available.

In the Europe to North America Summit-to-Summit event last Saturday, the 13th of May, a total of 36 European summits and 18 North American summits were activated. Despite abysmal radio conditions with deep fading and high band noise levels, several trans-Atlantic QSOs were made, including some summit to summit contacts. Overall everyone enjoyed the event and many are already looking forward to the next event on the 18th of November, when it is hoped that conditions will be significantly improved.

Mexican telecoms regulator IFT, the Instituto Federal de Telecomunicaciones, has approved amateur operation on the new WRC-15 60m amateur Secondary allocation of 5351.5 to 5366.5kHz. Maximum power permitted is 20W EIRP. Separately, the Icelandic authorities have decided to extend the experimental license privileges for radio amateurs in the 5MHz band until the 31st of December. The privileges are for 5260 to 5410kHz, with 100W EIRP. Mode of emission: CW, USB, PSK-31 and other digital modes. Currently 25 TF licensees have permits for 60 metres.

Several papers for the International Amateur Radio Union Region 1 2017 general conference are now online. These include C3, General Matters; C4, HF; C5, VHF and microwave; and C7, EMC. They can be downloaded under the heading ‘conference papers’ at tinyurl.com/GB2RS-2105A. There is also an RSGB Forum on these and other papers at tinyurl.com/GB2RS-2105B.

Bletchley Park opened a new exhibition this week, celebrating the centenary of Bill Tutte’s birth. In World War Two he was an elite codebreaker and renowned mathematician. Due to the secrecy surrounding his work, his contribution is sometimes overlooked, but his successes were on a par with those of Alan Turing. After the War, Tutte worked on many civilian projects including graph theory, which laid foundations on which today’s internet search engines are built. Full details of the exhibition, which is free with admission to the Park, can be found at www.bletchleypark.org.uk. RSGB Members can download a free admission pass to Bletchley Park from the RSGB website.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday 19th May.

NOAA’s prediction that the solar flux index would tend towards 80 last week turned out be wrong, as it stayed steadfastly in the low 70s. However, the prediction of poor geomagnetic conditions turned out to be right, with the K index hitting four on Wednesday, with worse to come. Nevertheless, there was DX to be had and evenings on 20 and 30 metres are proving to be useful as the bands remain open later.

Daytime maximum useable frequencies tend to be lower during the summer than they are in winter, but higher at night. This is because there is more molecular nitrogen due to heating effects in summer, and as this is harder to ionise than monatomic oxygen the Total Electron Content, or TEC, is lower. However, the TEC of the night-time F layer in summer tends to be greater than in winter, which is why night-time maximum usable frequencies can be higher.

Next week the solar flux index should remain in the mid 70s, but we are in for a turbulent time thanks to another coronal hole. A high-speed solar wind stream could push the K index up to five or six at the beginning of the week, with depressed maximum usable frequencies and noisy bands. However, the latter half of the week should be more settled and the bands could recover.

Meanwhile, we are into the Sporadic E season, which is providing good short-skip openings from 7MHz upwards at times. The strongest signals may be found on 28 and 50MHz, where noise levels are lower.

And now the VHF and up propagation news

This coming week we have an emphasis on low pressure, which means tropospheric openings may be hard to find, although there could be some end of night surface-based inversions with misty dawns. These could give short-lived lifts until the day’s heating breaks down any inversion.

Low pressure in the summer often produces some large showers or thunderstorms and these are often useful for rain scatter on the GHz bands. There are plenty of weather radars online that will show where these are.

Last week brought reports of rain scatter reception of the Bell Hill Microwave Beacon cluster across Southern UK and the GB3FNY and GB3CAM 10GHz beacons further north, but no reports of UK QSOs. By contrast, a large number of QSOs were reported from stations on the continent.

Sporadic-E has been putting in an appearance recently, so check for openings from 10m up to 2m. Check clusters and beacons and set aside a few minutes late morning and late afternoon to check the VHF bands.

Random meteor scatter continues on the low VHF bands, with the Cetids shower increasing the sporadic meteor background. Monitor and call on 50.280MHz and 70.280MHz with MSK144 mode to check activity.

Moon declination goes positive overnight so moon windows will lengthen as the week progresses. Losses fall to a minimum at perigee on Thursday, when the moon is at its closest point to Earth, but note that the Sun is close to the Moon that evening so the noise levels will be high for a while.

And that’s all from the propagation team this week.
