GB2RS NEWS
Sunday 27th June 2010 The news headlines Ofcom releases report on PLT Oman now on 6 metres CISPR seeks plasma TV interference experiences Last Wednesday Ofcom published its long-awaited report, The Likelihood and Extent of Radio Frequency Interference from In-Home PLT Devices. This 156 page report assesses the likelihood of interference to various users of the radio spectrum over the next decade. The main conclusion is that action is needed to reduce the interference footprint of PLT devices, and that this action could take various forms. The Society is considering the report in detail prior to initiating discussions with Ofcom about the follow-on actions it intends to take.We expect the position to become clearer over the next few weeks and months. The Omani Telecommunications Regulatory Authority has now allocated the band 50-52MHz to the amateur service on a secondary basis. The international standards committee responsible for EMC matters, CISPR, have launched an information-gathering campaign, specifically aimed at determining the extent and seriousness of interference from plasma TV receivers. Initially they have asked national standards organisations for this data and, in the UK, BSI contacted our Regulator, Ofcom. They posed the simple question, asking how many complaints have there been? Ofcom indicated that they had received only 12 to 15. Over the last few years, the EMC Committee have received many more complaints from members, but no recording system is in place. So, we now need your help. If you have suffered, or are suffering now, from interference from a plasma TV receiver we need to know. All that you have to do is send a very brief e-mail to . We only need to know the number of interference cases, no details, and no names/addresses. Please act as soon as possible, since the timescale for gathering this information is very tight. The RSGB Convention that takes place between 8 and 10 October has a wide variety of talks and lectures over the weekend. One of the latest talks to be confirmed is by David Johnson, G4DPZ on the current status of amateur satellite communications. He will also update the audience on the FUNcube satellite project. It is hoped that live satellite demos will take place as passes allow. Bookings for this popular event are already up on last year and you can find details of weekend packages or day tickets at www.rsgb.org.uk/rsgbconvention. The RSGB VHF Field Day takes place next weekend, 3 and 4 July. Although this is basically a 24-hour contest, there are exceptions. The 50MHz part takes place during the first eight hours and the 70MHz part takes place during the last eight. It is interesting to note how VHF NFD has developed over the years. At one time there were just a few categories and the only awards were for portables, but now there are two categories for fixed stations as well, Open and Restricted. For full details of the rules, go to the RSGB Contest website at www.rsgbcc.org/vhf and click on the calendar for 3 or 4 July. Jersey Amateur Radio Repeater Group has got its repeater GB3GJ back on the air.

Outside traders did brisk business at the last year's show and it is hoped to be able to accommodate many more at this year's event. There will also be a large area for car booters. Pitches can be booked via the National Hamfest website at www.nationalhamfest.org.uk. South Bristol ARC will be starting a new Intermediate course on 1 July.

There are rules on which bands can be used at certain times, so please check the rules before taking part. Now the solar factual data for the period from the 14th to the 20th of June, compiled by Neil Clarke, G0CAS on the 21st of June. Sunspots were visible every day except for the 15th and the 16th. The sunspot groups were small and only produced one C class solar flare which occurred on the 14th. Solar flux levels declined slightly from 73 units on the 14th to 69 by the 19th. The average was 71 units. The 90 day solar flux average on the 20th was 75 units, that's one unit down on last week. The 90 day solar flux levels have declined since late March when 83 units was recorded. X-ray flux levels varied little day to day and averaged A4.9. Geomagnetic activity started at quiet levels but by the 15th a coronal hole disturbance arrived, this peaked on the 16th with an Ap index of 19 units. The average was Ap 8 units. Solar wind data from the ACE spacecraft saw solar wind speeds increase from 360 kilometres per second to 600 kilometres per second by the 16th. Wind speeds then gradually declined. Particle densities were low except for the 15th which increased to 22 particles per cubic centimetre. On the quiet day the Bz varied between minus 3 and plus 4 nanoTeslas and between minus 9 and plus 7 nanoTeslas on the 16th which was the most disturbed day. Strong Sporadic-E occurred on most days on frequencies up to 70MHz, though there were also substantial periods when sporadic-E was not present. F2-related propagation at HF tended to be a bit below expected levels as a consequence of the midweek disturbance. And now the solar forecast. Without an upsurge in sunspot activity then solar activity is expected to be at very low levels. There are no signs that an upsurge in imminent, but as we know things can change with very little warning. Solar flux should be in the 70's for most of the week. Geomagnetic activity is expected to be unsettled for the next few days due to a recurring coronal hole. Activity should subside to quiet levels from midweek onwards. MUFs during daylight hours at equal latitudes should be around 18MHz for the south and 15MHz for the north. Darkness hour lows are expected to be about 11MHz. Paths this week to India should have a maximum usable frequency with a 50 per cent success rate of around 19MHz. The optimum working frequency with a 90 per cent success rate will be about 15MHz. The best time to try this path will be between 0900 and 1700 hours. Sporadic-E is expected to take place most days on the lower VHF bands with openings up to 144MHz possible now that we are at the peak of the summer season. And that's all for this week from the propagation team.
