VK7 Event
Meet the Voice BBQ
Don VK7AY lets us know that Sunday March the 21st. is the date of this years "MEET THE VOICE" BBQ again at Ross at the same venue, the ROSS CARAVAN PARK, and the members of the Tasmanian Sewing Circle net will be pleased for your company.
The invitation is open to ALL Amateur Radio operators and their families to come along and enjoy the comradeship that abounds and to put a face to that voice you have heard on air for a long time but have never had the opportunity to meet in person.
Registration will be from 10AM on the Sunday morning, a BBQ will be provided for those wishing to Cook their own, but of course Ross is well catered for with food outlets if you prefer.
In the mean time give thought to inviting as your guest one or more of our senior amateurs to travel with you, be assured they would appreciate the thought, and no doubt they will enjoy the chance to be part of the days events and also Meet A Voice.
This is a day of friendship and a not for profit venture. A Registration cost of $5.00 per member or member family is to cover cost involved in organisation and any surplus funds have been in the past been handed to the repeater licensing and maintenance fund.
I can report that to date also ALL monies received for Registration have gone to the repeater fund as the generosity of individual amateurs has more then covered any expenses involved, and for that we thank those amateurs.
Ray VK7VKV has again offered to organise a car boot sale on the day for those with pre-loved amateur radio bits and pieces to dispose of , please contact him for further information, that is Ray VK7VKV.
Look forward to greeting you at Ross.

Northern News
Northern Tasmanian Amateur Radio Club
NTARC's Annual General meeting is only a little over two weeks away now. Yes, it might be a little less exciting than the usual meeting regime, however it is the one time when the members can have a real influence on the club and how it moves forward through the year.
We'd encourage you to come along and let your voice be heard. Just to entice you to come along, we'll have a $2 raffle for two bottles of wine. We hope to see you at Alanvale campus of the Tasmanian Skills Institute, at 7.30pm Wednesday the 10th of February.
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.
If you need to get a call book, you had better shake a tail feather and get in touch with Ann VK7FYBG to get yours before they're all gone.
The coffee meeting on Monday will be held in picturesque Lilydale at VK7YUMs café shop. Come along and enjoy a coffee and a chat.
Allen VK7AN and Joe VK7JG have been busy climbing mountains again, this time with Ben Lomond in their sights. The 70cm repeater VK7RBH on 438.050 MHz has been treated to a new antenna, and it has given the old girl a new lease of life. I'm sure NTARC members will join me in thanking Joe & Allen for their work maintaining the repeater network across the north of the state.
You may remember before Christmas, Jason VK7ZJA had problems keeping his dual band Nagoya NL770R mobile antenna upright at highway speeds. I'd proposed a short term solution, but really we need a more permanent solution. That wonderful invention, heat shrink tubing, comes to the rescue!
Selecting a suitable size piece of heat shrink to place over the folding joint of the antenna ensures it won't fold over while driving, and has the added advantage of keeping rain and moisture out of this vulnerable section of the antenna, hopefully keeping it performing like new for longer.
Thanks from
(Jason VK7ZJA, NTARC Secretary)

Radio and Electronics Association of Southern Tasmania
10th Model Makers and Collectors Exhibition
Will happen on the 20-21 March 2010 at the Derwent Entertainment Centre. REAST has attended these exhibitions and presented amateur radio to the public.
As the quote from the movie "The Dish" says….
"It is a chance for science to be daring"
The exhibition is great chance for REAST to show Hobartians how dynamic and interesting our hobby is.
From emergency communications, TARGA comms, satellites, Amateur Radio on the International Space Station, DXpeditions, DX, morse code, packet, optical communications, amateur radio direction finding, mobile and portable operation, IRLP, echolink, Amateur TV, the list is endless and it makes for some great demonstrations at the exhibition.
We are looking for volunteers who would be prepared to come along and help out on the stand, talk with people interested in the hobby, maybe loan some equipment for the exhibition and/or help setup.
The committee is excited about the opportunities this presents for the promotion of the hobby and will be out at the DEC telling the pubic all about our great hobby.
So, if you would like to be involved then contact Gavin VK7HGO or a committee member ASAP.
Also a reminder that we only have 8 2010 WIA Centenary callbooks left so, if you would like one then contact me or leave your name on the whiteboard at the clubrooms.
Also check out the WIA Centenary merchandise, if anyone is thinking of purchasing items they are of good quality, I have the vest and have seen the polo top.
(Cheers, Gavin, President, VK7HGO)

ATV Experimenters Night
We had a fantastic roll-up last Wednesday night. We now have the four studio cameras full setup and operating.
We started with a show and tell of recent project of VK7TW in a precision AZ/EL mount for portable operation made fully from some very interesting recycled items ranging from WWII radar units to clothes dryers!
Our main presentation was some public domain NASA videos from the Apollo 17 mission.
This Wednesday night will see some more show and tell of interesting items and on air interviews along with three video presentations about the Parkes Radio Telescope.
So, if you are interested in receiving analogue ATV on a Wednesday night from around 7:30pm and you have a UHF TV antenna pointed toward the Queen's Domain then try tuning your analogue TV down the UHF TV band to SBS and then tune a little lower and you will probably find our ATV signal on 444.25MHz.
We also have a signal going out on digital Satellite TV standard - DVB-S on 1283MHz and you will need a digital satellite receiver and suitable antenna to receive this signal.
We get underway around 7:30pm in the ATV studios. So, if you would like to be involved in ATV come up to the domain and see and experience was amateur television is all about. We guarantee you'll be impressed….HIHI.
Hope to see you along.

Satellite News
Satellite Summary
JARL Publishes FO-29 Return-to-Operations Schedule
Mineo Wakita, JE9PEL reported this week that FO-29 ground controllers at JARL plan to open the satellite for amateur radio use. FO-29 may not remain operational after eclipses due to power budget issues but operations are planned according to the schedule that can be found at the AMSAT website.
Depending on the power budget JARL may need to selectively cancel operations. Operators are reminded to please use as low power as necessary on the uplink to complete their communications.

AO-51 Returned to Normal Attitude
Drew KO4MA who is AMSAT-NA VP Operations lets us know that on 9 January the magnet on AO-51 was repolarized to again favour the northern hemisphere. There may be some rapid fading as the nutation dampers do their job over the next few weeks. The command team appreciates all the reports and observations during this experiment.
--------------------------------------
OSCAR-11 Reception Reports Wanted
During the period - 30 November 2009 to 14 January 2010 good signals have been intermittently received, and decoded. Sometimes signals have been very strong, although frequent changes in polarisation have been observed. The satellite was not heard during solar eclipses, which now occur during the afternoon and evening passes over the UK.
Please send reception reports to the address that can be found on the email and internet editions of this broadcast.
xxxxx(AT)amsat.org (replace xxxxx by g3cwv) or post to amsat-bb. If you have a file, please discuss it with me, before sending it!

HISTORY News
How did Clipsal get it's name…simple really!!!
As most people know Clipsal is a popular Australian brand of electrical accessories and it started in Adelaide and now has factories in many places. It is now majority-owned by Schneider Electric as of 2004.
Clipsal was established by Alfred Gerard in Adelaide in 1920, selling a range of adjustable sheet metal fittings which joined the various imported conduits of differing diameters found in Australia at the time.
This fitting was the product that gave the Clipsal company it's name ("clips all" - Clipsal). Alfred's son Geoff eventually took over the company, and it soon spearheaded several manufacturing breakthroughs, including the invention of the first all-Australian switch in 1930.
The company also did early research and development on thermoplastics in the 1950s.
These days Clipsal Integrated Systems, a division of Clipsal, was responsible for the creation of the C-Bus protocol used in home automation systems.

Technology News
Siemens gurus hit 500Mbps with white LED lights, dare you to blink
You know what's better than wireless power?
Nothing, frankly. You know what comes darn close? Wicked fast transmissions through thin air.
Researchers from Siemens have just shattered their own record for wireless data transfer using white LED light, hitting a whopping 500Mbps while working in collaboration with the Heinrich Hertz Institute in Berlin.
The old record sat at "just" 200Mbps, but the new speeds are helping to take Visible Light Communication from a hopeful technology to a serious contender in the space.
These same researchers were also able to show that a system using up to five LEDs is capable of beaming out data over long distances at up to 100Mbps.
