Do you enjoy Amateur Radio or are you a keen Shortwave Listener?
Are you willing to contribute to the global amateur radio community? How? By simply doing what you enjoy best - listening and reporting intruders, whilst you listen or communicate via the HF bands or even suspect a pirate on the VHF and UHF bands.
All you need to do is simply file a report on any potential intruders you hear:
* Frequency (in kHz) - Bandwidth
* Time (UTC)
* Day of the Month,
* Country if you know
* Bearing (if available)
* Remarks (calls if known, language, locations, names, sked times)
* An audio sample, if possible
How do I report an intruder?
If we are successful within the IARU Region 3 in confirming, detecting and evicting intruders from the HF bands, we will share this success with you all. We need to ensure the Amateur Radio bands are available for your enjoyment and especially during an emergency situation.

On Tuesday, September 2, the League celebrated the 140th anniversary of the birth of ARRL's co-founder and first President, Hiram Percy Maxim, W1AW. Maxim -- born in 1869 -- decided a national organization for Amateur Radio was in order after he needed a "relay" station in Agawam, Massachusetts to pass a message he was sending from Hartford to Springfield, Massachusetts. In honor of The Old Man's (TOM) birthday, the ARRL is holding a week-long Special Event, where eligible amateurs may add /140 to their call signs. A complete list of who may add /140 can be found on page 20 of the September 2009 issue of QST. Hams who work at least 25 /140 stations can earn an attractive certificate; this certificate can be endorsed in increments of 25 QSOs, up to 100 http://www.arrl.org/news/stories/2009/08/17/11025/?nc=1.
Maxim was no stranger to technology. He entered the Massachusetts Institute of Technology (Class of 1886) and graduated at the tender age of 16. Through the activities of his son Hiram Hamilton Maxim, TOM became interested in Amateur Radio. In 1908, he filed for a patent for a firearms silencer the patent was granted the following year. Maxim used this technology to make silencers for guns, motor exhausts, safety valves and air releases. In all, Maxim received 59 patents, most of them in the field of mechanical engineering.
In 1928, Maxim, along with other dignitaries of the day -- including Thomas Edison -- attended a party at the home of George Eastman, the founder of Kodak. TOM was an avid film buff and was even involved in the early days of motion pictures. Check out this video (available on YouTube) of a dapper Maxim at Eastman's party
"I hope everyone enjoys our Special Event honoring Hiram Percy Maxim," said ARRL Chief Executive Officer David Sumner, K1ZZ. "I know if TOM was alive today, he would be on the air, having a ball!" Maxim, together with Clarence Tuska, founded the ARRL in 1914. Maxim served as President of the ARRL from its inception until his death from complications stemming from a throat infection in 1936. -- Thanks to Howie Lash, AE0KU, for bringing the YouTube clip to our attention

One of the hard things for all types of club is keeping the momentum going. One of the problems that amateur radio clubs face is developing activities that are inclusive of the majority of members. When we think about this, we realise that the hobby is very diverse in the areas that can attract personal interest - homebrew can be anything from kits to replicas, antennas to transceivers, analogue and digital. Field activities can be QRP, contest and DX or any mix of all these things.
So within our clubs we need to find ways of including people in ways that can allow them to share their interests and encourage others in growing their knowledge and experience of this great hobby. Not every one wants to be a paper hanger and cover the shack walls with certificates and awards and not every one is an avid collector of QSL cards but we can share why these things make our personal enjoyment of the hobby better and the tricks we have learned to do things better. Our personal enthusiasm for the aspects of the hobby can be a big incentive for some one else to dip their toe in the water.
It has been around for a long time and is a bit corny but the following can be a way of helping us focus on how we can help our club.
Someone has said that membership of any organisation is made up of four bones....
There are the "wishbones" who spend all their time wishing someone else would do the work....
There are the "jawbones" who do all the talking but very little of anything else....
Next comes the "knucklebones" who knock everything that everyone else tries to do....
And, finally, there are the "backbones", who get under the load and do the work.
What kind of member are you?
Australian 137 kHz beacon on-the-air
Drew Diamond, VK3XU, is operating a CW beacon on 137.4 kHz every Saturday and Sunday afternoons and evening.
Drew has activated a 50-watt transmitter into an inverted wire antenna from Wonga Park.
He would like to receive signal reports, they can be sent to his email address:
firstname.lastname@example.org provide date, time, signal strength and grid locator (eb QF22ML).
Due to the very low antenna efficiencies at this frequency, Drew estimates his effective radiated power is 6 milliwatt. His signal has been heard in Melbourne, Sale and Sydney.
Enigma Weekend at Bletchley Park
Over the weekend 5th and 6th September, Bletchley Park in Buckinghamshire will be marking the 70th anniversary of the arrival of Alan Turing and Gordon Welchman with an Enigma Weekend.
Their usual Enigma exhibits will multiply when over 70 more previously top-secret machines from all around the world will be on display. Another highlight will be a talk on Saturday 5th September by Prof. Tom Perera, W1YP, entitled The U-Boat Menace and the Enigma. He will have an exhibit of his discs and various Enigma machines too.
Bletchley Park is open from 10.30 am each day and entry costs 10 pound per adult, which entitles you to visit as many times as you like for 12 months.
NZART Has a CD to loan on Bletchley Park. See:
It wasn't long ago when we were reporting that the theft of copper and other conductive metals was rampant. Power lines were cut down for their copper content, pipes in buildings under construction were ripped away, and wiring was disappearing.
But that's no longer the case as the global recession has resulted in a drop in demand for most metals with copper among the hardest hit.
The price of copper reached an all-time high in mid-2008 of more than $4 per pound on the world market, with the greatest demand from China. That price then plummeted to $1.50 per pound shortly after the global economic recession began last fall. This makes it not very profitable for a thief to risk his or her life for less than the price of a hot dog from a street vendor.
Add to this newly enacted laws like one in California that requires scrap metal dealers buying bulk metal to get a photo ID from anyone bringing in the items and to delay payment for three days. It also requires recyclers to photograph the items, pay only by check and take the seller's thumbprint.
Science Daily reports that solar cells could soon be produced more cheaply using nanoparticle inks that allow them to be printed like newspaper or painted onto the sides of buildings or rooftops. This to absorb sunlight and produce electric power.
The article cites the work of University of Texas chemical engineer Brian Korgel. Korgel is hoping to cut the cost of producing high output solar cells to one tenth of their current price by replacing the standard manufacturing process for solar cells.
Right now photovoltaic cells are made using a gas phase depositing system that must be carried out in a vacuum chamber and requiring high temperatures. For the past two years, Korgel and his team have been working on this low-cost, nanomaterials solution to photovoltaic manufacturing. He believes that nanomaterial inks could be printed onto a surface using a roll-to-roll process on a plastic substrate or stainless steel. Because of this the prospect of being able to paint the inks onto a rooftop or building is not far fetched as one might at first believe.
His team has so far developed solar-cell prototypes with efficiencies at one percent but notes they need to be about 10 percent. He says that if he can get the level to the 10 percent mark, then there's real potential for commercialisation. He says that then you could see this new production technique being used in three to five years. For hams involved in public service and emergency communications work, such a source of sunlight power used to charge battery banks would mean communications could continue even if the power mains we out of service for an extended period of time.
Funding for the research comes from the National Science Foundation, the Welch Foundation and the Air Force Research Laboratory. The complete story is at
Chicken feathers may help cars use hydrogen fuel in the future.
The feathers would not be the fuel, but they could help store it.
Hydrogen, the most common element in the universe, has long been touted as a clean and ample energy alternative to fossil fuels. When hydrogen reacts with oxygen, instead of yielding pollutants as fossil fuels do, it simply generates water.
Unfortunately, hydrogen is hard to store and transport. Hydrogen vehicles currently keep it in tanks in either liquid or pressurized gas form. As a pressurized gas, it takes up roughly 40 times as much space as gasoline, and as a liquid it needs to be kept at extremely low temperatures.
"Using currently available technology, if you had a 20-gallon tank and filled it with hydrogen at typical room temperature and pressure, you could drive about a mile," said researcher Richard Wool, director of the Renewable Resources program at the University of Delaware in Newark.
It has been suggested by Wool and his colleagues that superheated chicken feather fibres could hold vast amounts of hydrogen. They first looked at chicken feathers because they are extraordinarily cheap - the United States alone generates some 6 billion pounds of the feathers per year.
Chicken feather fibres are mostly composed of keratin, the same protein found in nails, scales, claws and beaks. When carefully heated for precise times to specific temperatures, the carbon-rich surfaces that result on the fibres attract hydrogen, somewhat like how activated charcoal filters can pull out impurities from liquids or gases.
The heating process can also form hollow tubes between the fibres, strengthening their structure, and make them become more porous, boosting their surface area and thus their capacity to store gas.
One can then pump gas into the fibres and store it at high pressure, and to release the gas, one just depressurises it or raises the temperature.
