VK7 REGIONAL NEWS BROADCAST FOR SUNDAY 26TH OCTOBER 2008 --------------------------------------------------------------------224KM CLOUDBOUNCE TESTS Well last week it a 165km cloudbounce contact between Rex VK7MO and David VK3HZ in VK3, this week it’s a 224km test across the top of Tasmania. http://reast.asn.au/optical.php#20081011 On the night of the 22nd of October Rex VK7MO and Joe VK7JG went portable in Northern Tasmania from one side of the island to the other using Bass Strait as a 224km path. Joe was transmitting a 627nm (red light) signal from at Cape Portland in the North East and Rex was receiving using the 10mm square Avalanche Diode receiver at Stanley in the North West. The transmitter was driven by a VC-TCXO stable oscillator which enabled Rex who was using the Spectrum Lab software to monitor for a signal at a 1milliHertz bandwidth. The signal peaked at 18dB using the very narrow bandwidth however this was not enough to use WSJT to complete a contact. There was very little cloud and it is hoped that in future better cloud cover will provide an increase in signal strength to enable a WSJT contact to be completed. The report complete with pictures and greater detail can be found at the address on the email and internet editions of this broadcast. http://reast.asn.au/optical.php#20081022 Congratulations to Rex and Joe and all involved. (Justin, VK7TW) --------------------------------------------------------------------JOTA REPORTS Our first JOTA report comes from the North and the NTARC crew and Tony VK7YBG. JOTA 2008 started out much like any other with a heavy day of setting up tents, food and camping facilities, antennas and radios – Ann and myself I completed all this on the Friday though and it made for a much easier event with radio operation and enjoying the weekend being the prime concerns. All went well for the whole weekend with SSTV, IRLP and FM 1 simplex being the preferred modes with the crew on "Barnards Peak" (In truth known as the Fingerpost Hill on the other side of town) keeping all manner of conversations and SSTV pictures ready for the scouts at a moments notice. Phil's idea (VK7JJ) of running a show and guess game using SSTV and the many and varied pictures of his Australia wide travels proved to be something everyone enjoyed including myself as it was my first time operating this mode. Special thanks go to all volunteers involved, especially Phil (JJ), Lyn (FLYN) and the crew on "Barnards Peak" running the remote station, Ann (FYBG) for all her hard work during the whole exercise providing food, drinks and all her work setting up and packing up and to Peter (KPC) for liaising with the scouts, providing great ideas and equipment for the event and his hard work over the course of the weekend. (Regards, Tony, VK7YBG) -------------------------------The next JOTA report comes from the New Norfolk Scout Group and from Ray VK7VKV and Brian VK7BDW: 18 members of the New Norfolk Scout Group attended a camp at Curringa Farm at Hamilton. Apart from the usual JOTA activities, the scouts were given plenty of practice at lashing and guying as all of the masts used were constructed by the youth members. A Moxon rectangle on 20m was erected on 4 lashed poles in the paddock. Contact were made with many other JOTA stations with the highlight being a contact with HB9S the station at the International Scouting Bureau in Switzerland. Looking forward to next year with plans already being made of a series of long wires across the paddocks. Brian VK7BDW takes up the story…Curringa Farm in Hamilton is a working sheep farm and scouts were given a demonstration of sheep shearing. I was really impressed that the previous week was spent in designing antenna's and the supports for the JOTA weekend. With Grou leader Ray VK7VKV supervising and giving technical advice ably supported by son Ben who is VK7FGBS. Operators on the Sat and Sunday were Ray and Ben and Brian set up his Icom 706 as another station VK7BDW. We operated on 20,40 and 80 meters and some interesting contacts resulted from NZ, Switzerland and USA plus local Scouts were heard. One of interest was a group in Canberra who were operating from Honeysuckle Creek where their Scouts talked with Astronauts in the ISS. 2 Although all the bands were not too kind it was a great weekend. Scout Leader Gerald Parsons thanked all involved and it is hoped an even better JOTA will happen next year. (73 Brian VK7BDW) -------------------------------Our next JOTA report is from The Lea Scout Camp overlooking Hobart and is from Gavin VK7HGO: Gavin was the sole operator at The Lea and reports it went very well with VHF contact via IRLP and repeaters from VK2,VK7GGA,VK7HDM. On HF there were many contacts which included: VK3s, VK7GGA, VK5s, VK7ABB, VK2s and VK7ZJJ. Unfortunately, Murphy struck and when the kids were not around the band was open, ie. Saturday on 7MHz was there all the time, but on Sunday it was in and out. Gavin reports he heard all states on 7MHz. (Cheers, Gavin, VK7HGO) -------------------------------Thomas VK7NML manned the station out at the Brighton Girl Guides and reports: The Girl Guides were very excited to get on air, having never used a transceiver before. They made many contacts with scouts and guides in Snug via VK7GGA and a couple with VK3SBG. The station was based at the Brighton Primary School, and even attracted the interest of other passing locals too. Thomas took some pictures of the station that are available at the address that appears in the email and internet editions of the broadcast. http://reast.asn.au/events.php#jota (73, Thomas, VK7NML) -------------------------------Our final JOTA report today is from DannyVK7HDM from the Glenorchy Scout Hall Camp Out: Saturday afternoon saw Mark, VK7FMAC, Graham, VK7ZGK and Danny, VK7HDM Danny turn up at the Glenorchy Scout hall to set up a radio station that would be run from 5pm Saturday till 1pm Sunday. With a lot of work from Graham, Mark and Noel and Danny we set up a 2MHz to 30MHz Dipole for all HF work and a ½ wave vertical for 2m. 3 Radios on hand were a Kenwood TS 430, Kenwood TS-2000X and for VHF and Icom IC-910H. With Graham departing late afternoon to spend some time with his family it was Mark and Danny who camped with the Glenorchy Group. Saturday afternoon saw 7MHz wide open and we worked many stations well into the night stations from VK3 and VK4. 80m was not good from the location however, 40mtrs was very good till we gave up and went to bed Saturday night. We also worked VK7FGGT Greg on 146.500 for about an hour Saturday afternoon talking to lots of the kids. Most of the other VHF time was spent talking with VK7SAA at The Lea. The Glenorchy Group Looked after us very well, supplied food and drinks all night. Sunday Morning was a late rise out of bed for everybody but we soon got into the activities again. All VHF work was between us and VK7SAA stationed at The Lea. HF was very quiet and we had a chat with VK3SAW for about an hour also worked ZL2AMI Bob from Wellington New Zealand for half an hour. Bob used to do JOTA in NZ for many years so was glad to chat with the scouts. Bob also used to build electronics equipment and some has ended up on our Mt Wellington so all the group thought that was cool. 1pm came around very quick and VK7ZGK arrived to help us pack up so with the help of Mark, Noel, Graham and myself we had our station packed up in no time. The highlight was working Bob ZL2AMI who new a lot about Hobart and Mt Wellington. Another highlight was having most of the Scout Group wanting to talk on the radio. Danny would like to thank Mark VK7FMAC, Graham VK7ZGK and Noel Gadd for their efforts this weekend to make it all happen. Looking forward to next year (Best Regards, Danny, VK7HDM) --------------------------------------------------------------------VK7 EVENTS CALENDAR And a quick reminder of the events and broadcasts across VK7: 4 REAST – November 1st – First Saturday Afternoon - Aviation Theme meet at Reg VK7KK’s QTH for BBQ at 12 Noon. http://reast.asn.au/events.php#satarvos REAST – November 5th –Special General Meeting – Queens Domain Clubrooms – 8pm http://reast.asn.au/events.php#SGM NTARC – November 12th David Murray from Centrelink at Alanvale TAFE at 7:30pm http://www.wia.org.au/clubs/vk7/NorthernTasmaniaAmateurRadioClub/ REAST – November 12th – Tour of Heart 107.3 Radio Station – 7pm at Radio Station – No ATV Night. http://reast.asn.au/events.php#HeartFM VK7 HAMFEST – December 6th – Central Highlands of Tasmania Hamfest – Miena – starts 10am. http://www.qsl.net/charct/ --------------------------------------------------------------------NON-COMMERCIAL FOR SALES & WANTED For Sale Tony VK7DXX has for sale an Icom IC-701 with 20 amp power supply needs band selector switch cleaned for $250, a PRM80 programmed for 70cm for $50.00 and a Yaesu FT-530 dual band Handheld for $150.

Next Saturday the 1st November, the Saturday afternoon group is holding their first monthly activity meeting. The theme for November's meet is aviation. The group will meet at Reg VK7KK's QTH at 725 Acton Rd Acton (PLEASE NOTE CHANGE OF LOCATION from last week’s broadcast). If you have trouble finding the group, give us a yell on 147.425 simplex and we will direct you to us. 5 We will meet up at 12 noon at VK7KKs for a BBQ lunch (BBQ and meat supplied - couple of bucks donation if partaking). We will have a general discussion about aviation and listen to some comms from Hobart Airport before heading to the airport just before 1pm where we will visit the Rotor Lift complex and have a tour through this area, the Bureau Of Meteorology facility for a guided tour and the Fire fighting and Marine Rescue section where the Commander of the day will explain their role in ensuring they are ready for any emergency whether on land or at sea involving an aircraft in the area. The trip will finish up by the tower where plans are still being made as to whether a trip inside of the tower will be permissible or a talk from an Air Traffic Controller on the outside of the tower will occur. Obviously all of the plans are subject to change depending on whether a search and rescue mission is on or severe weather etc. which may tie up the resources of the organizations that we are visiting. We must know numbers as we are restricted to around a dozen visitors. Of course if the day is over subscribed we will simply duplicate the event in a couple weeks time so no one misses out. To lock in your spot please email Tony, vk7ftcl at the email address toneman@bigpond.com. http://reast.asn.au/events.php#satarvos 73’s (Tony, VK7FTCL) --------------------------------------------------------------------November Meeting - Special General Meeting In two week’s time on Wednesday November 5th @ 8pm there will be a Special General Meeting.

(REAST Committee) --------------------------------------------------------------------Education and Training 6 Last Tuesday night started the first night of the next Foundation Licence training course with six eager participants. The course will probably run over three nights with the third night being a recap and practical night with the assessment night on the 11th of November. If you are interested in attending the course and/or the assessment and it could be an assessment for other than just the Foundation licence then please let Reg VK7KK know ASAP and he can be contacted by ringing mobile: 0417 391 607 or email: regemm@ozemail.com.au ASAP. http://reast.asn.au/events.php#FoundationLicenceCourse (Reg, VK7KK, REAST Education Officer and Assessor) --------------------------------------------------------------------ATV Experimenters Night Last Wednesday night was a mixed bag of ATV programs being broadcast including a live patch from the digital set top box from NASATV. Thanks to Ken VK7DY and Ian VK7ZIF for realigning the satellite dish and LNB to receive NASATV. For those who don’t know, NASA have a free to air satellite channel that broadcasts continuously a feed from their facilities around the world. The programs include live feeds, set pieces on different missions and the research they are undertaking. We were fortunate enough to see an interview with the current ISS crew and Richard Garriott along with many other interesting programs. We also dismounted the omnidirectional ATV antenna that we were having trouble with and Ian VK7ZIF is taking a look at this for us. Thanks Ian. This antenna will enable a more even signal spread around Hobart and hopefully enable more ATV viewers in the near future. There will be another ATV night presentation this week starting around 7:30pm. How do you receive ATV on an ATV night well, ATV goes out on 444.25MHz – just below SBS on the UHF TV Band. If you have an antenna pointed somewhere toward the Domain why not try tuning down the low end of the UHF TV band and give us a call on what you are seeing and hearing. See you there. http://reast.asn.au/events.php#ATVnights (Justin, VK7TW) --------------------------------------------------------------------7 SATELLITE NEWS ISS SSTV Pictures Abound Over the last week whilst Richard Garriott W5KWO has been on the International Space Station there has been much activity with Richard sending down SSTV pictures on most passes and even talking with amateurs and schools on the ground. Steve VK7OO and Justin VK7TW have been receiving many SSTV pictures that has traced Richard’s time on the ISS even down to his saying goodbye on the last day. Justin has been posting some of these to the ISS Fan Club website along with many other hams around the world. Take a look at the web address on the email and internet editions of this broadcast. http://www.issfanclub.com/ http://members.ozemail.com.au/~justingc/ar2.html#SSTVfromISS --------------------------------------------------------------------TECHNOLOGY NEWS Creating Wireless Network Using Visible Light As reported in ScienceDaily on Oct. 16, 2008 — Boston University's College of Engineering is a partner launching a major program, under a National Science Foundation grant, to develop the next generation of wireless communications technology based on visible light instead of radio waves. "Imagine if your computer, iPhone, TV, radio and thermostat could all communicate with you when you walked in a room just by flipping the wall light switch and without the usual cluster of wires," said BU Engineering Professor Thomas Little. "This could be done with an LEDbased communications network that also provides light – all over existing power lines with low power consumption, high reliability and no electromagnetic interference. Ultimately, the system is expected to be applicable from existing illumination devices, like swapping light bulbs for LEDs." Little envisions indoor optical wireless communications systems that use white LED lighting within a room – akin to the television remote control device – to provide Internet connections to computers, personal digital assistants, television and radio reception, telephone connections and thermostat temperature control. 8 Moreover, since this white light does not penetrate opaque surfaces such as walls, there is a higher level of security, as eavesdropping is not possible. LED lights also consume far less energy than RF technology, offering the opportunity to build a communication network without added energy costs and reducing carbon emissions over the long term. "This technology has many implications for automobile safety," Little said. "Brake lights already use LEDs, so it's not a stretch to outfit an automobile with a sensor that detects the brake lights of the car in front of it and either alerts an inattentive driver or actively slows the car." http://smartlighting.bu.edu http://www.sciencedaily.com/releases/2008/10/081006130548.htm (Sourced from the ScienceDaily website) --------------------------------------------------------------------BPL NEWS 2008: The Year Broadband Over Powerline Died Karl Bode on the 16th of October on the DSL Report Website reports…. Manassas, Virginia was the first US city to see a real, non-trial launch of broadband over powerline (BPL) technology. However, BPL has floundered the last few years because of its inherent potential for interference with amateur and emergency radio, its irrelevance in the face of next-generation speeds, and the unavoidable fact that many utilities simply didn't want to be broadband providers. Manassas was a particular hotbed of interference debate, with enthusiasts complaining the FCC (who for years cheerleaded the technology a little too enthusiastically) didn't properly test the network and used bogus data to make the case for BPL. The FCC's dream technology, embraced in the hopes it would help them obfuscate the fact their policies have created an uncompetitive duopoly, hasn't been faring well. Last May, a flagship BPL trial in Dallas operated by DirecTV and Current Communications was sold to the local utility. In other words, another network that was supposed to be a shining example of broadband over powerline's promise is likely going to be shelved. The city may potentially keep the network operational to monitor the city's electric grid, but says the technology simply isn't viable as a major broadband option. That's something we've been saying for going on half a decade, though many didn't want to hear it. http://www.dslreports.com/shownews/2008-The-Year-Broadband-OverPowerline-Died-98477 9 http://arstechnica.com/news.ars/post/20081023-stick-a-fork-in-it-abroadband-over-powerline-post-mortem.html (Karl Bode and the DSL Report Website via BPL & Ham Radio Mailing List) --------------------------------------------------------------------WEB & EMAIL EDITION EXTRA BITS!!
