The news headlines:

  • IOTA Contest next weekend

  • Sked group launched on Facebook

  • RSGB Centenary Day film available online

The annual Islands on the Air contest takes place next weekend on 27 and 28 July. The most sought-after multipliers are those assigned to offshore islands and a list can be found at www.rsgbiota.org/info/directory/EU.pdf. This year a special Centenary Commemorative Certificate is available. Everyone who enters and submits a log of contest QSOs will be eligible. To qualify, simply make 100 QSOs along with 20 multipliers and send your log in. It is recommended that you make more than 100 QSOs and 20 multipliers to allow for any errors. Details can be found at www.rsgbcc.org/hf/rules/2013/riota.shtml. The IOTA Contest is also an opportunity to gain some points towards your HF Centenary Award.

A new group has been formed on Facebook for amateurs wishing to schedule contacts with other amateurs. So if you need a particular contact for an award, or just a chat, then go to www.facebook.com/groups/hamsked and have a look.

Paul Whatton, G4DCV has produced this short film of the RSGB’s historic Centenary Day event which was held at Bletchley Park on Friday, 5 July 2013. To view this six-minute film, go to http://rsgb.org/news/.

The RSGB’s Centenary Convention, sponsored by Martin Lynch & Sons, takes place over the weekend 11th –13th October at Horwood House, just a few miles outside Milton Keynes. One of the highlights of this year’s event is the lecture by Michael Wells, G7VJR. He will be giving a presentation on his venture to Easter Island where he and his colleagues operated as XR0YG in March, on all bands 160m through to 10m, CW only. Electricity on Easter Island was subject to frequent blackouts, which caused a few problems, but after six days on the air they’d made some 24,000 QSOs. More details on the RSGB Centenary Convention can be found on the front page of the RSGB website, www.rsgb.org/.

All G0 calls are being combined into a single group and Tony Roberts, G4KZZ has kindly accepted the challenge of being the new sub-manager. Over the next 3 to 4 months all cards and envelopes stocks will be transferred to Tony from other sub-managers. The RSG website www.rsgb.org/news/ has further details.

G100RSGB, the special event callsign celebrating the RSGB Centenary will be operated today by Chelmsford ARS using 80 to 6m as well as 2m and 70cm. Monday and Tuesday it’s the turn of Colchester ARS on the 80 to 10m bands using SSB and CW. On Wednesday and Thursday Essex CW Club will be using the call for CW on the HF bands. Felixstowe ARS take over the callsign on Friday and Saturday using the 80 to 6m bands as well as 2m and 70cm. Next Sunday Loughton & Epping Forest ARS will be on the air using the 80 to 6m bands plus 2m and 70cm. Details of how to get your QSL card are on the RSGB website, www.rsgb.org.uk, under the Operating drop down menu, clicking on Centenary Station.

A Full licensee is needed for a Hampshire Scout Group JOTA event in October 2013. Due to current overseas posting of the normal licensee, a stand-in is urgently required. They must be able to provide own HF equipment for the duration and be able to create a station at Bishop's Waltham Scouts HQ in the upper section of Scout HQ building. A central support is already erected for dipole. Respondents please contact Andy, G0JLX via e-mail to g0jlx@mail.com.

Now the contest news

Today sees the Low Power Contest taking place between 0900 and 1600UTC. There are two power categories, 10W and 3W, and sections for fixed and portable stations. That makes four categories, and a trophy is awarded to the winner of each. Using the 3.5 and 7MHz bands, CW only, the exchange is signal report, serial number and power.

The 4m Trophy Contest has the potential for some DX working. Last year 168 stations were recorded in the logs in 31 squares and ten countries. Running from 1000 to 1600UTC today, the exchange is signal report, serial number, locator and postcode.

Also on today, the UK Microwave Group’s 24 to 248GHz contest takes place from 0900 to 1700UTC. Using all modes the exchange is signal report, serial number and locator.

The 50MHz UK Activity Contest takes place on 23 July from 1900 to 2130UTC. Using all modes on the band the exchange is signal report, serial number and locator.

On Tuesday 23 July the SHF UK Activity Contest will take place between 1900 and 2130UTC. Using all modes on the 2.3GHz and up bands, the exchange is signal report, serial number and locator.

The Centenary IOTA Contest that takes place on 27th and 28th July will be the biggest HF event of the month. There are 12- and 24-hour categories. The IOTA Reference is part of the exchange, the one for mainland Britain being EU-005 and mainland Ireland is EU-115. Offshore islands have different references. All the European references can be found on the internet at www.rsgbiota.org/info/directory/EU.pdf. Running from 1200UTC on the 27th until 1200UTC on the 28th on the 3.5 to 28MHz bands, the exchange is signal report, serial number and IOTA reference.

The UK Microwave Group 5.7 to 24GHz contest takes place next Sunday, the 28th, from 0600 to 1800UTC. Using all modes the exchange is signal report, serial number and locator.

And now the solar factual data for the period from Friday the 12th to Thursday the 18th of July compiled by Neil Clarke, G0CAS on Friday the 19th of July.

Several sunspot groups were visible every day with most quiet and stable. However, two were medium sized and magnetically complex but these could only produce a couple of small strength C class solar flares each day. In total 16 C class solar flares took place. Solar flux levels gradually declined from 118 units on the 12th to 111 by the 17th. The average was 114 units. The 90 day solar flux average remained the same level as last week at 121 units. X-ray flux levels showed little variation day to day and averaged B3.8 units. Geomagnetic activity started the period at unsettled levels and then increased to sub-storm levels by the 15th with an Ap index of 35 units. The disturbance was probably due initially to a small coronal hole and then a coronal mass ejection. The average was Ap 16 units. Solar wind data from the ACE spacecraft saw solar wind speeds decrease from 560 kilometres per second on the 12th to 330 by midday of the 17th. Particle densities were moderate most days with a high of 22 particles per cubic centimetre during the 15th. Bz varied between a maximum of minus 10 and plus 3 nanoTeslas during the disturbance and between minus and plus 4 nanoTeslas on the quietest day. Radio aurorae took place from midday of the 14th till the afternoon on the 15th, but only a few contacts were reported from the UK. Sporadic-E propagation occurred every day, up to 70MHz.

And finally the solar forecast for the coming week. This week the quiet side of the Sun is expected to be looking our way. Therefore, solar activity is expected to be only at low levels with only C class solar flares taking place. Solar flux levels should be around 120 units at first but by the middle of the week a decline could take place. Due to a recurring coronal hole geomagnetic activity is expected to increase for most of the week. Activity could decline to quiet levels by next weekend. MUFs during daylight hours at equal latitudes should be around 21MHz for the south and 18MHz for the south. Darkness hour lows should be about 13MHz. Paths this week to the east coast of North America should have a maximum usable frequency with a 50 per cent success rate of around 17MHz. The optimum working frequency with a 90 per cent success rate will be about 13MHz. The best time to try this path will be between 1700 and 2200 hours UTC. Sporadic-E is expected to take place on some days.

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