Northern News
Northern Tasmanian Amateur Radio Club
Tony VK7YBG has set up a yahoo mailing group for those who might be interested in getting involved in WICEN in northern Tasmania. If you are interested in this, go to yahoo groups on the web and search for "wicennorth". I'm sure that Tony would be very pleased to hear from you.
A group of NTARC members including Joe VK7JG, along with David VK7NTD attended the repeater site at Snow Hill recently to find a grim sight. Originally, only the top section of the State Emergency Service tower had been reported as damaged, which is where repeater VK7REC lives. On arrival, it became apparent that the SES had meticulously dismantled the entire tower, not just the undamaged section, along with the heliax coax that fed the repeater antennae. Unfortunately this means that for the foreseeable future, VK7REC voice repeater will be off air while the options are considered. Some of the ideas being considered are to: do nothing or move the repeater to another commercial repeater site nearby if permitted. Since a new tower is very unlikely to be erected, and due to very limited antenna space on the fire watch tower, a third option could be to replace the repeater with a UHF one that requires minimum antenna mounting space. To do anything other than nothing will cost money, so it will be up to radio users of VK7REC to voice their support if they want the repeater facility to continue to be available.
The Annual General meeting is but only 10 days away now. We hope to see you at Alanvale campus of the Tasmanian Skills Institute, at 7.30pm Wednesday the 10th of February. As an added incentive to come along, a $2 raffle will be held for two bottles of wine on the night
the perfect accompaniment to those late night construction projects, so long as they're not 240 volt based circuits hihi.
Have you paid your annual NTARC membership fees yet? You'll need to be up to date with this to make your vote count at the AGM. Membership has been kept at $20 for the year, see Ann VK7FYBG if you need to make your payment.
Thanks from
(Jason VK7ZJA, NTARC Secretary)

CCARC News
http://www.my-x15.net/ccarc
The CCARC Inc is holding a garage sale on SUNDAY the 14th of FEBRUARY 2010 in conjunction with the Penguin History Groups Annual Bizarre. This will be held at the Old Penguin Railway Station and normally gets under way about 9.00 am
This event is for the sole purpose of raising money for the Club to help cover yearly ongoing costs of our infrastructure which is in place for all to use.
Now if any member, or non member for that matter, has some stuff in the shed that they are thinking of taking to the tip but are having trouble doing so because it might be a bit to good, then we have a very good solution to your problem, donate it to the garage sale, after all it will benefit your Club and the general amateur community rather than the tip shop.
For any items that you may wish to donate, but cannot attend the sale, drop off points will be notified on next weeks broadcast. The QTH of VK7EX in Ulverstone will be one of these points. So remember the sale date, SUNDAY the 14th of FEBRUARY 2010
--------------------------------------
If you are a non amateur or a short wave listener living in the North West, or West coast of Tasmania, and would like to become a licenced amateur radio operator, then come along to a meeting and find out about this interesting hobby. If you cannot make the meeting but would like to find out more about the hobby then contact the learning facilitator, Keith Winkler VK7KW, or any of the committee members.
Full contact details are available on our website which can be easily found by a "Yahoo" or "Google" search of CCARC TASMANIA
Cheers from
(David, VK7DC, Secretary, CCARC)

ATV Experimenters Night
Another great roll-up with a very special guest straight from the Australian Antarctic Bases. We welcomed Berndt Wulf VK5ABN who came along with Warren VK7FEET. Berndt was originally DL5JR before immigrating to Australia in 1982.
http://vk5abn.ping.net.au/index.php?mode=home
Berndt had the privilege of operating HF maritime mobile on the voyage back from Antarctica and made many DX contacts on the way back. Berndt heads back to the Adelaide hills today.
Our ATV studio desk anchors were Warren VK7FEET and Graham VK7ZGK and it was a wonderful casual chat to get the night underway.
Then it was on to our main presentations which included three different tours of the Parkes Radio Telescope, then into the talk given by Richard Garriott the recent space tourist to the ISS and then the 1956 RCA documentary of how records are made called - The Sound and the Story.
Much was also going on in the background to configure the video distribution amps and video switch matrices to accommodate the video mixer which arrives in about a week.
We are also installing an Optimod-TV multiband compressor, loudness controller and Hilbert clipper in the audio chain prior to the transmitters so our audio quality should improve in the near future.
We take a break next week as it is the first Wednesday night of the month and get back underway on Wednesday the 10th February.
This Wednesday night will see some more show and tell of interesting items and some very interesting videos courtesy of K7AGE.
Hope to see you along in a fortnight's time

Intruder Watch News
QRM from Security and Home Control Systems
Roger Harrison VK2ZRH through the Spectrum-Issues mailing list alerts us to another possible source of localised interference on the 40m band.
Nigel Holmes from the ABC raised the alarm after using a spectrum analyser to detect a signal that has a continuous sweep from about 7.1MHz to 8.5MHz at a two to five second rate.
It was traced to a neighbour who just installed the X10 security and home control system which is using the spread spectrum protocol and under 100mw however at 300 feet it makes 40 meters unusable.
Roger's comment on the list is
..
"Mmmm.? Looks like we may need to be alert to the appearance of these systems in Australia."

The FISTS Military Appreciation Award
The North American FISTS CW Club announces a new operating achievement award, the USA FISTS Military Appreciation Award. To earn the award, make 2-way CW QSOs with 100 FISTS members who are U.S. military veterans or currently serving in the U.S. military.
Logs must include the following QSO information for the station worked: Call, Name, Date, Band, FISTS Number, and Branch of Military Service. Each FISTS number may be worked only once for one point. Remember that it is the FISTS NUMBER that counts not the call sign. If a person changes their call, you cannot work them again for credit, because they will still have the same FISTS number.
Anyone, FISTS and non-FISTS may earn the award. The award is free; including postage, to current FISTS members who submit qualified logs.
For more information on this award take a look at the website on the email and internet editions.

Flexible antennas can multiply tune
Antennas aren't just for listening to the radio anymore. They're used in everything from mobile phones to GPS devices.
Research from North Carolina State University is revolutionising the field of antenna design - creating shape-shifting antennas that open the door to a host of new uses in fields ranging from public safety to military deployment.
Modern antennas are made from copper or other metals, but there are limitations to how far they can be bent - and how often - before they break.
NC State scientists have created antennas using an alloy that "can be bent, stretched, cut and twisted - and will return to its original shape", says Dr Michael Dickey, assistant professor of chemical and biomolecular engineering at NC State and co-author of the research.
The researchers make the new antennas by injecting an alloy made up of the metals gallium and indium, which remains in liquid form at room temperature, into very small channels the width of a human hair.
The channels are hollow, like a straw, with openings at either end - but can be any shape. Once the alloy has filled the channel, the surface of the alloy oxidises, creating a 'skin' that holds the alloy in place while allowing it to retain its liquid properties.
"Because the alloy remains a liquid," Dickey says, "it takes on the mechanical properties of the material encasing it."
For example, the researchers injected the alloy into elastic silicone channels, creating wirelike antennas that are resilient and that can be manipulated into a variety of shapes.
"This flexibility is particularly attractive for antennas because the frequency of an antenna is determined by its shape," says Dickey. "So you can tune these antennas by stretching them."
While the alloy makes an effective antenna that could be used in a variety of existing electronic devices, its durability and flexibility also open the door to a host of new applications.
For example, an antenna in a flexible silicone shell could be used to monitor civil construction, such as bridges. As the bridge expands and contracts, it would stretch the antenna - changing the frequency of the antenna and providing civil engineers information wirelessly about the condition of the bridge.
Flexibility and durability are also suitable for military equipment, since the antenna could be folded or rolled up into a small package for deployment and then unfolded again without any impact on its function.
Dickey thinks these new applications are the most likely uses for the new antennas, since the alloy is more expensive than the copper typically used in most consumer electronics that contain antennas.

Space News
Mars Rover now a Stationary Science Platform
On Australia Day 2010 NASA announced that after six years of unprecedented exploration of the Red Planet, NASA's Mars Exploration Rover Spirit is no longer a fully mobile robot. NASA has designated Spirit a stationary science platform after efforts during the past several months to free it from a sand trap have been unsuccessful.
"Spirit is not dead; it has just entered another phase of its long life," said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington.
"We told the world last year that attempts to set the beloved robot free may not be successful," adds McCuistion. "It looks like Spirit's current location on Mars will be its final resting place."
Ten months ago, as Spirit was driving south beside the western edge of a low plateau called Home Plate, its wheels broke through a crusty surface and churned into soft sand hidden underneath.
After Spirit became embedded, the rover team crafted plans for trying to get the six-wheeled vehicle free using its five functioning wheels the sixth wheel quit working in 2006, limiting Spirit's mobility.
At its current angle, Spirit probably would not have enough power to keep communicating with Earth through the Martian winter. Even a few degrees of improvement in tilt might make enough difference to enable communication every few days.
"Getting through the winter will all come down to temperature and how cold the rover electronics will get," said John Callas, project manager at JPL for Spirit and its twin rover, Opportunity. "Every bit of energy produced by Spirit's solar arrays will go into keeping the rover's critical electronics warm, either by having the electronics on or by turning on essential heaters."
Steve Squyres, a researcher at Cornell University and principal investigator for Spirit and Opportunity said that "Degraded mobility does not mean the mission ends abruptly. Instead, it lets us transition to stationary science."
One stationary experiment Spirit has begun studies tiny wobbles in the rotation of Mars to gain insight about the planet's core. This requires months of radio-tracking the motion of a point on the surface of Mars to calculate long-term motion with an accuracy of a few inches."If the final scientific feather in Spirit's cap is determining whether the core of Mars is liquid or solid, that would be wonderful -- it's so different from the other knowledge we've gained from Spirit," said Squyres.
Tools on Spirit's robotic arm can study variations in the composition of nearby soil, which has been affected by water. Stationary science also includes watching how wind moves soil particles and monitoring the Martian atmosphere.
Spirit may have been stopped, but it hasn't stopped discovering the secrets of Mars.

EMS News
WiFi Suit: Neighbour Sues Neighbour For Using Electronics
The Santa Fe reporter newspaper reports that a Santa Fe man who alleges he suffers from "electromagnetic allergies" is suing his neighbour because she refuses to turn off her gadgets, he claims.
According to the Santa Fe Reporter, Arthur Firstenberg, the plaintiff, has been sleeping at friends' homes or in his car to avoid the electromagnetic waves created by his neighbour's cell phone, wireless network, computer, compact fluorescent lightbulbs and dimmer switches.
Firstenberg claims he suffers from Electromagnetic Sensitivity, or EMS, which induces "nausea, vertigo, diarrhoea, ringing in the ears, severe headaches and body aches, crippling joint pains, insomnia, impaired vision, impaired muscular control," as well as other potentially life-threatening ailments.
According to Firstenberg, he first started experiencing symptoms when he was in college in the 1980s and has been a vocal opponent of
wireless systems being established in public buildings, though he has met with little success.
When Firstenberg first hired Monribot to cook meals for him in his home, Monribot had initially made concessions by turning off her phone and computer. However, when she moved in next door, she refused to keep her phone, computer and wireless network turned off when not in use. When asked if she could use a landline instead of her iPhone, Firstenberg says the neighbour "flatly refused without explanation."
The battle against Wi-Fi isn't one Firstenberg is fighting alone. He's part of a group of Santa Fe residents who are pursuing legal means to remove all Wi-Fi hotspots from public locations because they claim the wireless internet waves aggravate their "electromagnetic allergies." To add merit to their case, they are classifying their "allergy" or "sensitivity" as a disability and are claiming the Americans with Disabilities Act, which prohibits discrimination based on disability.
