RSGB GB2RS NEWS BULLETIN for 10th. September 2017.

Posted on September 8th, 2017


Sunday the 10th of September 2017


The news headlines:

  • Keep hurricane frequencies clear

  • Report VDSL interference NOW

  • 100kW IARU news bulletins


Hurricane Irma is getting widespread news coverage and will affect many countries in the Caribbean. There are the usual American nets on 14.265 and 14.325MHz to gather information on the storm. Several other frequencies will be used and amateurs in IARU Region 1 are asked to please take steps to avoid interference with emergency operations. You can find out which frequencies are most used in which country on the IARU Region 1 website,

The RSGB EMC Committee has been investigating VDSL broadband interference on the HF amateur bands for three years now. This has generated a lot of historic data. However, despite active lobbying, Ofcom and Openreach contend that the 150 or so reports from 50,000 amateurs do not indicate a major problem, when viewed from the perspective of 9.5 million VDSL installations. To increase the amount of evidence available, the RSGB EMC Committee has set up a survey at to collect current signal levels at the frequencies of VDSL band transitions. These measurements indicate the presence and strength of interference. Please fill in the survey with your current readings, even if you have reported them before, and encourage your friends to do so. The EMC Committee plans to present its findings at the RSGB Convention in October, then use them to persuade Openreach to take further action. The survey closes on 30 September. This is the last chance we have to prove how many people are affected by this interference. Your report could make all the difference to cleaning up the bands.

Following a request from the Radio Society of Kenya, the Kenya state radio regulator has advised that a new 60m allocation has been granted between 5275kHz and 5450kHz on a secondary basis. All modes are permitted, with a maximum power of 400W PEP.

From the 16th to the 22nd of September, the IARU Region 1 Conference will take place in Germany. 130 delegates from the 96 member societies will discuss issues related to the amateur radio service. RADIO DARC will report current news on the conference in six daily special short wave transmissions. These will be made in partnership with the Austrian Broadcasting Transmitters Corporation. The programmes will be in English. In Western Europe, listen out between 1800 and 1830UTC on 9540kHz between the 17th and 22nd. The broadcast power will be 100kW.

Discount rates are available for taking the UK amateur radio exams at the RSGB Convention on 14-15 October. The Foundation and Intermediate, taken together on the 14th, are £45 instead of £60, while the Intermediate and Full exams on the 14th and 15th are £52 together instead of £70. For the adventurous and well-prepared, you can take all three exams for £73 instead of £97.50. Foundation and Intermediate candidates must have had their Practical Assessment signed off before the Convention. Those wanting to take an FCC test for an US licence can do so on the Sunday. Full details of all of these exam offers are at and it is important to note that the booking deadlines are quite soon. The Advanced deadline is 22 September, while the Foundation and Intermediate must be booked by 29 September.

The Citrus Belt Amateur Radio Club of San Bernardino, California will host the 18th annual Route 66 On The Air special event between the 9th and the 17th of September. The event offers radio amateurs a chance to perhaps relive their own Route 66 memories and to celebrate the famed highway’s 91st anniversary. There will be 21 stations, two of them rovers, operating in or around the major cities along Route 66. Using the callsigns W6A to W6U, details of frequencies can be found at Please be aware that some of the stations may have to move their operating frequencies to accommodate hurricane traffic. Radio amateurs who operate while driving on Route 66 may take part in the event by using the designations mobile 66 or /66 after their callsigns. Each participating club will issue its own commemorative QSL card to celebrate this event. Certificates are available.

The DXCC Most Wanted entities list has been updated on ClubLog. The top three are P5, North Korea, 3Y/B, Bouvet Island and FT5/W, Crozet Island. The complete list is at

The 7163 Group will be active as HD8M from Isabela Island in the Galapagos, IOTA reference SA-004, between the 14th and 21st of September. Activity is planned for the 160 to 6 metre bands using CW, SSB and digital modes, primarily FT8. QSL via ClubLog OQRS, direct to WB2REM with an SASE or via the bureau through KG0YL.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 8th of September.

Last week the sun caught everyone out. While NOAA predicted the solar flux index would be in the mid 70s, the sudden appearance of a large number of sunspots pushed it up to 183 on Tuesday, although it had calmed down to 122 by Wednesday. This had a major impact on the bands, with openings up to 10 metres being reported, though many or all of these may have been due to Sporadic-E. To be fair to NOAA, these spots were only just appearing around the edge of the sun as last week’s report was being prepared.

Unfortunately, this new sunspot activity also resulted in numerous X-class solar flares, their associated coronal mass ejections and a proton storm. The K index was pushed up to five on Tuesday and four on Wednesday and Thursday, impacting HF conditions adversely. Next week the larger spots will have rotated off the sun’s visible surface, so the question is: what will follow them?

At the time of writing it looks like the Sun may calm down a little, although there is evidence of some new spots growing. NOAA predicts the solar flux index may decline into the 80s or 90s by the end of the week, with unsettled geomagnetic conditions from around the 13th to the 17th.

The good news is that each week we edge closer to better autumnal HF propagation, so expect higher maximum usable frequencies and better DX. October should be even better, so make sure your antennas are ready.

And now the VHF and up propagation news.

After last week’s class X9.3 solar flare, keep your beams to the north and look for any auroral propagation on six, four and two metres. The big sunspot group will have rotated off the sun’s visible surface by now, but, as we said, it may not be the last one we see during this period.

The 2017 Sporadic-E season struggled into the first week of September, but we sense we must be near the end now. That leaves Tropo as the next best option for some DX at VHF. Unfortunately, for much of the next week the UK weather pattern is dominated by low pressure, bringing unsettled and windy weather – so Tropo also looks like a non-runner. Such changeable weather, often showery, may produce some rain scatter on the GHz bands, otherwise it’s thin pickings for weather-related propagation modes.

With only minor meteor showers this week, continue to look around dawn for the best random meteor scatter contacts.

We have positive Moon declination all this week. So, combined with low losses as we approach perigee on Wednesday, it’s a good week for EME with long morning and daytime Moon windows.

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