How many DXers are there in the World?

clublog uniques3You may find this article of interest, written by Clublog Author Michael G7VJR?


''A question that comes up in the context of DXpeditions is just how many uniques are there out there? We’re aware that there are at least 50,000 (a record set by T32C in 2011) but can we estimate the full size of the population?

I ran a short database analysis against Club Log’s records for QSOs made after 1 January 2012. How many unique callsigns are worked in each continent?.....''

Solar wind stream buffeting Earth's magnetic field

CaptureDuring last 24 hours solar wind stream buffeted Earth's magnetic field causing geomagnetic storms around the poles. Geomagnetic conditions were short lived reaching G1 - Minor geomagnetic storm levels (Kp=5). At those levels weak power grid fluctuations can occur, minor impact on satellite operations is possible, migratory animals are affected at this and higher levels and aurora is commonly visible at high latitudes.

At about 05:13 UTC on August 4, Phi angle became positive (away) and total field, temperature and wind speed began to rise. Wind speed rose from 350 km/s to a maximum of 586 km/s at 23:00 UTC.​

The Bz component turned mostly southward for several hours and reached -13 nT by 20:25 UTC. This sequence of events brought unsettled levels of activity and a single period of minor storm conditions between 15-18 UTC.

During the same period, major storm levels were observed at high latitudes.

Geomagnetic field activity is expected to be at mostly quiet levels in the absence of any transient solar wind features. Recurrent coronal hole high speed streams are expected to bring unsettled to active conditions on August 5, 6 and 8, August 18-19, 21-23 and 31.

There is a slight chance for minor storm conditions on August 5 and again on August 31.

Saturn, Titan, Rings and Haze

titanbusy cassini 960This is not a solar eclipse. Pictured above is a busy vista of moons and rings taken at Saturn.

The large circular object in the center of the image is Titan, the largest moon of Saturn and one of the most intriguing objects in the entire Solar System. The dark spot in the center is the main solid part of the moon.

The bright surrounding ring is atmospheric haze above Titan, gas that is scattering sunlight to a camera operating onboard the robotic Cassini spacecraft.

Cutting horizontally across the image are the rings of Saturn, seen nearly edge on. At the lower right of Titan is Enceladus, a small moon of Saturn. Since the image was taken pointing nearly at the Sun, the surfaces of Titan and Enceladus appear in silhouette, and the rings of Saturn appear similar to a photographic negative. Now if you look really really closely at Enceladus, you can see a hint of icy jets shooting out toward the bottom of the image. It is these jets that inspired future proposals to land on Enceladus, burrow into the ice, and search for signs of extraterrestrial life. To view larger image click here.

Having trouble identifying noise?

iaru1Have you ever had trouble identifying different noises on the Bands? Maybe a usual one which we class as 'Radar', Digital Modes such as PSK or RTTY or maybe just something that arrives at short notice and you haven't heard it before?

Check out a few of these noises on the links listed below. Its likely you will find the answer here;

- Plasma-TV on 3500 kHz (USB)
- Plasma-TV on 3500 kHz (AM)
- Plasma-TV (standby condition) on 3500 kHz
- TV switching power supply on 14000 kHz

2013 IARU HF Championship Contest.

gr2Every year the IARU (International Amateur Radio Union) holds an international amateur radio contest organised by the ARRL.

The contest is usually held on the second full weekend of July, beginning 1200 UTC Saturday and ending 1200 UTC Sunday (July 13-14, 2013). Both Single and Multi operator stations may operate the entire 24-hour period.  Detailed information can be found on the ARRL IARU HF Championship website.

The objective of this contest is for radio amateurs to contact as many other radio amateurs, and especially IARU member society HQ stations, around the world using the 160, 80, 40, 20, 15 and 10 meter bands, by Morse (CW)  and Voice  (SSB).

GR2HQ is the callsign being used by the UK Headquarters Station. This the callsign of the team which represents the RSGB and UK amateurs.

This intention behind this website is to provide information specific to the GR2HQ entry, how and when to work the station, the awards available to those contacting the station,and of course QSL information.

2013 is the Centenary of the RSGB, an organisation that played a major part in the IARU and of course the early days of radio communications.

British Airways first Airbus A380


BA A380British Airways has released photos of the first Airbus A380, MSN95, painted in the airline's red, white and blue livery this week. Here ius a little 'useless' information for you;

It took 24 painters at Airbus' Hamburg hangar two weeks to complete using eight movable platforms up to 30 meters from the ground.

They applied five coats of red, white and blue gloss paint (2,300 litres of paint) covering an area of 3,500 square meters and with a total weight of the paint totalling 650kg.

Check out this great You Tube video of the handover to BA and also of the aircraft in flight (click here)


Yorkshire Air Ambulance airlifts 5,000th patient

K640 BBC pictures 063A drummer who had to be cut from a car by firefighters after a head-on collision became the 5,000th patient to be airlifted to hospital by Yorkshire Air Ambulance (YAA).

Chris Parr suffered broken ribs, a fractured breast bone and a fractured knee in the two-car smash at Marsden, near Huddersfield. The 48-year-old, a drummer with Huddersfield band State of Confusion, was airlifted to Leeds General Infirmary. He is now recovering at home and has been visited by YAA paramedics Sammy Willis and John Baxter.

 Chris said: ''I could not believe how quick the response was to the accident and all the emergency services were just fantastic. It is amazing to think I am the 5,000th patient they have helped. The air ambulance does such a vital job and I'm so grateful to them.''

YAA was set up 13 years ago and operates two air ambulances from bases in North and West Yorkshire providing a life saving emergency response service to five million people. To keep both helicopters in the air, the charity needs to raise £9,990 per day, equivalent to £3.6 million per year. The only support YAA receives is through the secondment of their paramedics from Yorkshire Ambulance Service NHS Trust.

But demand for the air emergency response service is increasing. Last year YAA attended 933 incidents, and transported 431 patients directly to hospital for treatment, up from 376 patients the previous year.

A YAA spokeswoman said: ''This is an amazing achievement, which couldn't happen without the wonderful support we receive from Yorkshire people and businesses. So we would like to take this opportunity to say a massive thank you to everyone who helps us to keep saving lives in Yorkshire.''


Big Southern Sunspots

interest strip2

One of the biggest sunspot groups of Solar Cycle 24 is emerging near the sun's southeastern limb.

AR1785 has a "beta-gamma-delta" magnetic field that harbors energy for powerful X-class solar flares. Another active region trailing behind it, AR1787, is only slightly less potent, with a magnetic field capable of M-class eruptions. NASA's Solar Dynamics Observatory photographed the sprawling complex during the early hours on today (5th July).

These sunspots are a sign that the sun's southern hemisphere is waking up. For most of the current solar cycle, the northern half of the sun has dominated sunspot counts and flare production. The south has been lagging behind--until now. June brought a surge in southern sunspots, and the trend is continuing in July. This "southern awakening" could herald a double-peaked Solar Maximum due in late 2013-early 2014.

The largest dark cores in sunspot complex AR1785-1787 are as wide as Earth, making the ensemble an easy target for backyard solar telescopes. Amateur astronomers are encouraged to monitor developments, as NOAA forecasters estimate a 40% chance of M-flares during the next 24 hours.

Chinese Space Station transits the Sun...


Earlier this week in the sunny skies above the south of France, China's experimental Tiangong-1 space station flew directly in front of the sun. Using a filtered 6-inch telescope, astrophotographer Thierry Legault recorded the station's silhouette alongside big sunspot AR1775.

Most people are familiar with the 450-ton International Space Station. Fewer, perhaps, know about China's 8.5-ton Tiangong-1 (Heavenly Palace-1). It was launched in Sept. 2011 to establish a foothold in Earth orbit for China's fledgling space program. Tiangong-1 was briefly boarded by taikonauts (Chinese astronauts) in June 2012, and a second group is onboard now. Three Taikonauts arrived on June 13, 2013, on a 15-day mission to practice rendevous and docking maneuvers and to gain experience living in space. Their expedition is attracting little attention in Western press, but it is being widely followed in China. Earlier this week, more than 60 million students and teachers at 80,000 Chinese schools watched a live lecture by the crew of the Tiangong-1.

See the Tiangong-1 before it goes! Spaceweather's Simple Flybys app turns your smartphone into a field-tested space station tracker. It works for both the ISS and the Tiangong-1.

Most spectacular Moon of 2013 - tomorrow....


On June 23, 2013 we will experience a truly super supermoon. The full moon that falls on June 23, 2013 at 11:32 UTC, will not only be the closest to Earth for the year, but it will also appear the biggest full moon for 2013. It will also be about 30 percent brighter than an average full moon. Last supermoon was on May 24, 2013. And in 2011, we witnessed the moon's closest approach in 19 years.

Moon`s elliptical orbit is the main reason for the increase in its apparent size. About 50,000 km is the difference between the Moon`s apogee (it`s furthest point to Earth) and it`s perigee (it`s closest point to Earth).

The supermoon of June 2013 will be extra special, as the full moon coincides with it`s closest approach to our planet for 2013, at a distance of 356,991 km. Next time this event will occur is August 2014. It is also worth mentioning that between June 22 and June 25, 2013 the occurrence of "King tides" is expected
