The news headlines:

  • Report VDSL interference NOW

  • ARDF team heads to Lithuania

  • Valve Workshop at Computing Museum


For three years the RSGB EMC Committee has been investigating the problems of interference from VDSL broadband on the HF amateur bands and lobbying for action to reduce the problem. It has a lot of historic data, but both Ofcom and Openreach contend that 150 reports from 50,000 amateurs are not indicative of a major problem when there are 9.5 million VDSL installations deployed. RSGB EMC Committee has set up a survey at to collect current signal levels at the frequencies of VDSL band transitions, which 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 and 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 RFI. You could make the difference.

The RSGB Direction Finding team, which is entirely self-funded, is flying out to Lithuania this weekend for the 21st Region 1 ARDF Championships. There is a strong team in the M50 category, that is men aged from 50 to 59, with individuals competing in the M60 and M70 categories. Four separate competitions make up the Championships. There are Classic races on 2m and the other on 80m, where five transmitters send in sequence on a common frequency. FoxOring competitors receive a map giving approximate locations of the very low power transmitters, which are only audible for 100m or so. They use a combination of orienteering and radio direction finding skills to find the hidden transmitters. The event runs from Tuesday to Sunday and you can follow progress by looking for ardf2017 in your favourite search engine.

A Valve Workshop will be held on the 14th of October at The National Museum of Computing, Bletchley Park MK3 6EB. If you have a basic knowledge of electronics and can read an electronic circuit diagram then they will show you how electronics started for its first 50 years. Find out about valve history, how to handle and test valves and how valves are used in amplifiers, radios and computers. Full details, including those on a project for purchase can be found at

The RSGB HF Contest Committee plays a key role in the enjoyment of amateur radio by many RSGB Members. It is responsible for deciding the HF contesting strategy, organising the HF contesting calendar, setting the rules and providing clarification of the rules to the contest adjudicators. The current Chair of the committee, Nick Totterdell, G4FAL, is approaching the end of his agreed term and has stated that he is not seeking to be reappointed. Any RSGB Member may volunteer to take over the position of Contest Committee chair, which is a three-year appointment. If you would like to be considered, please write to RSGB General Manager Steve Thomas, M1ACB, via email to providing details of your amateur radio and other relevant experience.

The cross-band voice repeater aboard the International Space Station has been set up by the Russian team to help get telemetry from their satellites. Although some amateurs report communicating via the repeater, ARISS would like to remind amateurs that it has not officially been activated for amateur contacts. When the ARISS voice repeater is active and authorised for general amateur voice contacts the uplink frequency is 437.800MHz FM, downlinking on 145.800MHz FM downlink. Meanwhile, if you would like to try receiving the Tanusha telemetry, technical details are on the Southwest State University Space Activity page at

The National Hamfest takes place at the Newark & Nottingham Showground, Lincoln Road, Winthorpe, Newark NG24 2NY on 29 and 30 September.

If you want to operate the Hamfest Special Event Station, GB17NH, run by Camb-Hams, please bring your current licence with you.

The new Islands on the Air programme website is planned to launch officially in early September, when the current RSGB-sponsored website will be taken offline. According to IOTA IT Manager Johan Willemsen, PA3EXX, the new website is presently undergoing fine tuning. Software developers should be aware that the change to a new website may affect any application using data from the current website.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 1st of September.

Last week saw the solar flux index climb into the high 80s. Our prediction that the weekend’s ionosphere might be unsettled was partly correct, as the effects of a coronal hole pushed the K index to three on Sunday, but this quickly recovered. We are now seeing a shift from predominantly summer ionospheric conditions to autumnal. As the ionosphere starts to cool it experiences a shift away from predominantly diatomic molecules to more monatomic species. These are easier to ionise and, as a result, we can expect to see better conditions and potentially higher maximum usable frequencies as we move into September and October.

Roger, G3LDI reports that 15 metres was open to the US on Wednesday afternoon, which bodes well for the future. And G0KYA’s tests with 5W and WSPR on 20 metres resulted in him being picked up in Alaska around UK sunset, which was also very positive.

Now the bad news. A very large coronal hole on the Sun threatens to push the K index higher this weekend as a high speed solar wind impacts the Earth. This may result in noisy bands and suppressed MUFs, which could impact this weekend’s HF SSB Field Day operations.

NOAA predicts the solar flux index will be in the low to mid 70s next week. Once the coronal hole effects die away we may then get some more settled conditions. Either way, keep an eye on HF as you might be pleasantly surprised.

And now the VHF and up propagation news.

The end of the main Sporadic-E season is approaching rapidly now and, despite some 6m and 4m openings last Wednesday to Eastern Europe, such events will become much rarer in September. Check the beacons on 10m and perhaps 6m, but in general it’s back to meteor scatter for DX on the lower VHF bands now.

The prospects of Tropo should improve as we head into the quieter mellow days of autumn and high pressure becomes more commonplace. We should see a ridge of high pressure lasting until mid-week when the patterns flip to become dominated by low pressure. This means that Tropo will be worth investigating at first and with the ridge extending over much of the country most parts of the UK will get something out of this period. The changeover to low pressure-dominated weather patterns from mid-week is less useful, although if there are any significant spells of heavy rain or thundery showers, then rain scatter on the GHz bands is a possibility.

At this time of the year, very humid ex-tropical moisture from the States can become part of the train of low pressure systems that cross the Atlantic and make heavy rain more likely.

There are only minor meteor showers this week, so continue to look around dawn for the best random meteor scatter contacts

Moon declination is increasing again, going positive on Friday. Losses fall and Moon windows get later and longer as the week progresses, with the best operating times very late at night or early morning.

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