Northern News
Northern Tasmanian Amateur Radio Club
NTARC's November meeting this Wednesday will see a very special presentation by Rex VK7MO and Justin VK7TW talking about the latest generation of optical light communications equipment and techniques. The development of communications by visible light started out with experiments by Mike VK7MJ and Chris VK3AML, and given a digital flavour by Rex and Justin.
We'll make sure we get all the boring necessities of the meeting out of the way quickly to give maximum time for the star presenters… or should that be the star-light presenters hihi.
We'll kick things off at 7.30pm at Block B of the Tasmanian Skills Institute at Alanvale.
Coming up soon is the Spring VHF / UHF field day. Have you considered participating in this event? It's a lot of fun no matter how modest your equipment… just a little time and a good vantage point is all you need to make the most of this event on the weekend of the 28th and 29th of November.
Rumour has it that Karl VK7HDX and Jason VK7ZJA will perch themselves on the northern slopes of Mt Barrow, hoping to catch a duct or two to our northern neighbours.
Thanks from
(Jason VK7ZJA NTARC Secretary)

Next Club General Meeting and Xmas Dinner
The next General Meeting of the Club is scheduled for Saturday 5th. December, Venue to be advised. Jim VK7JH will be guest speaker at this meeting and will be giving us an insight into his travels during his extensive holiday trip earlier in the year.
Bookings have been made for the Club's Christmas Dinner which is to be on Wednesday 9th. December at the Bass & Flinders Restaurant, Ulverstone, 6.30 for 7.00PM sit down.
Members and friends will need to advise the Club in due course of their intention to attend for booking purposes and numbers.
As usual all persons welcome.
Welcome home Barry VK7FR
Some will remember that Barry VK7FR suffered a minor stroke several weeks ago, spending much of the time since in rehabilitation.
We are pleased to learn that Barry has made very good progress and has finally been allowed home permanently. His progress has been very good and we hope it is not too much longer before his distinctive golden voice is heard on the amateur airwaves.
Well done Barry.
Foundation License Assessments planned
It is planned to conduct an Amateur License Assessment later in the Month of November. The tentative date is Saturday 21st. Nov. with 3 candidates at this time.
If there are other people in the North West area who would like to sit for this exam, please advise the Club and we will accommodate you.
It is also perhaps timely to remind Tassie Amateurs that the Club has 2 Facilitators attached to the Radio & Electronics School, so if any amateur is thinking about studying for the Advanced License and would like a local Tasmanian Facilitator, then please also advise the Club as this can be arranged through the RES.
73's until next time

CCARC News
http://www.my-x15.net/ccarc
Cradle Coast Amateur Radio Club members are reminded that it's Inaugural Christmas Dinner/ Social evening at the Best Western Bass & Flinders Convention Room, Eastland's Drive East Ulverstone on Saturday the 5th of December with a roll up time of about 6.00 – 6.45 and a sit down at 7.00 pm.
The menu will be A La Cart rather than a set Christmas Style Dinner. If you are attending this event then please advise David VK7EX promptly of you intentions.
The Tasmanian Equine Endurance Riders Association is holding it's Tasmanian State Championship Title ride at Sassafras on Friday the 27th to Saturday 28th of November and have asked WICEN Tasmania South for assistance with providing communications and competitor tracking at base and checkpoints for the duration of the ride.
Due to the location of the event being in the north west of the state, WICEN Tasmania South have asked the Cradle Coast Amateur Radio Club for assistance in helping out with this event. The event starts at midnight Friday night and concludes around 6pm Saturday.
As some of the checkpoints are presumed to be in remote locations volunteers will need to be prepared for camping out for the duration. The preferred arrival time for radio operators is 12:00hrs Friday to allow setup and testing time in daylight but late arrivals up to 22:00 hrs Friday may be accommodated.
Amateurs who would like to participate in assisting with this event should contact David VK7DC for more details.
All members are notified there will be a general meeting of the Cradle Coast Amateur Radio Club at 1:30pm on Saturday, the 21st of November at the Penguin Lions club rooms 19 Ironcliffe road, Penguin. Please note that this meeting date has been moved forward by one week from the normal date, which is usually the last Saturday of the month.
The meeting is open to all members and non members alike. So, please remember that date change - Saturday, 21st of November.
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 the 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.

November Presentation
All you ever needed to know about Portable Antennas
A great big thank you to Phil VK7JJ and Lyn VK7FLYN (and Rosie) who came down to REAST last Wednesday evening for a great presentation of theory and practice about all things to do with portable antennas.
Phil ran through his vast experience with creating a practical multiband, quick, cheap, and easy portable antenna with maximum electrical efficiency that is wind and weather tolerant, that would get him back to a destination ie. VK7.
And Phil managed to cover all these aspects of antenna design along with claiming to have had more erections in the bush than anyone else…HIHI.
Phil has a great lecturing style and with copious use of the whiteboard Phil was able to relate the theory and practice for a subject that Phil obviously have much passion for.
The presentation was recorded for a future ATV broadcast and will be placed into the ATV Library very soon.
Thanks again to Phil and Lyn.

Saturday Afternoon Groups
Tony VK7FTCL lets us know that a date has been set for the trip to Hobart Airport. Saturday 12th of December is the day so if you wish to attend please get in touch ASAP to lock in your spot. We are restricted to the size of the group that can visit certain areas and these are filling fast. We already have confirmation from a couple of the areas including the tower and Rotorlift and just waiting word back from the others, but the likely itinerary will be starting the trip off at rotorlift looking at their rescue helicopters and a general run down on how they undertake their missions with a hands on look at their birds, a chat with the Australian Federal Police who will explain what their role is at airports around Australia, Fire and Rescue who will show us their range of fire fighting and rescue equipment and finishing off in the tower which is a highlight.
For more info or to book your spot please contact Tony at toneman(AT)bigpond.com.
On Saturday 5th December 2009 the Saturday Afternoon Group will be heading out for a "morning" field trip, hihi. We will be visiting the Bureau of Meteorology site at Hobart Airport. This trip will encompass the procedure to prepare the weather balloon for launch and then the tracking of it via radar. We will also look at the varied equipment used to monitor the weather, not only for Aviation but for the State in general.
Last years trip was fantastic. Dont miss this opportunity as space is very limited.
Again, contact Tony at toneman(AT)bigpond.com.

Technology News
Metamaterials Arrive in Cellphones
The following article appeared in IEEE Spectrum Magazine in October 2009 and was written by Saswato R. Das who is a New York City–based science writer.
The quest to build more-powerful multiband mobile handsets has gotten a boost from a relatively new class of materials. Called metamaterials, they are specifically engineered to have properties that do not occur naturally, such as the ability to bend light the wrong way. For manufacturers of mobile devices, recent advances in metamaterials promise a way to shrink size while still retaining multiband functionality.
LG Electronics' new Chocolate BL40 mobile handset, from its high-end Black Label Series, will incorporate a metamaterial antenna made by San Diego–based Rayspan, a start-up that's pioneering the commercialization of metamaterials. Metamaterials have allowed LG to "achieve the dramatically sleek, slim dimensions of the new LG Chocolate and unsurpassed radio-frequency capabilities," says Woo Paik, LG's president and chief technology officer.
Anirudh Srinivasan, an analyst with Frost & Sullivan, says, "Metamaterial antennas satisfy this void by enabling the antennas to be sized on the order of one-tenth the signal's wavelength and yet providing performance on par or better than conventional antennas sized one-half the signal wavelength, thereby providing a five times the size reduction."
Maha Achour, Rayspan's chief technical officer, says the antenna used in the LG handset is a few millimeters long and as thin as paper, and it simplifies the integration of both GPS and Bluetooth protocols. The same antenna array is also shared by the cellular and Wi-Fi radios within the handset.
Netgear's 2008 RangeMax wireless routers were the first commercial devices to use metamaterial. The Rayspan antenna allows the routers to reduce radio-frequency interference and boost the router's range.
The metamaterial antennas, which are fabricated directly on the router's printed circuit board, have proved to be robust with over 20 million metamaterial antennas in the market currently.
The major impetus for metamaterials research came from the work of Sir John Pendry of Imperial College London. In 2000, he wrote about creating a perfect lens with a metamaterial. He also theorized that you could design magnetic materials using structures made of nonmagnetic materials. For instance, although copper isn't magnetic, he hypothesized, a construction made of minuscule copper loops embedded on fiberglass should be. Experimentalists seized upon the idea, and as Pendry predicted, electromagnetic wave propagation through metamaterials is fundamentally different than through conventional materials.
Rayspan set out to harness metamaterials for wireless technology. "For 4G devices, you need to be able to handle multiple frequencies," Achour explains. "With conventional antennas, you cannot put two antennas together with coupling. Metamaterial antennas allow you to support four to six frequency bands." It is also difficult to get high performance from a small, ordinary antenna, she adds, but metamaterials make it easier.

== IN THE SKY THIS WEEK ==
The last quarter Moon is Tuesday November 10. In the morning Mars is readily visible in the eastern sky. Red Mars is in the constellation of Cancer and starts the week near the Beehive cluster. This will be readily visible to the unaided eye under dark skies, and will look quite nice in binoculars. On Monday November 9 the waning Moon is close to Mars, with the Beehive in between. Saturn is low in the morning sky this week. Bright white Venus is invisible the twilight glow and will not reappear until February. Jupiter is easily seen as the brightest object in the evening sky and is big enough to be appreciated in even the smallest telescope. Jupiter's moons are readily visible in binoculars or a small telescope.
This week also sees some interesting variable stars. The red giant Mira peaks in brightness on November 10 and can be seen in the eastern sky. On November 5th at 11pm AEDT the classic variable star Algol will be at its dimmest low in the northern sky, and you can watch it steadily brighten over the next few hours.
