Fwd: Lake Los Carneros ARDF report
by Marvin Johnston 11 Jan '07

11 Jan '07

A warmer-than-anticipated day made for a good turnout and excellent radio-orienteering at Lake Los Carneros, just west of Santa Barbara, on January 6, 2007. It was good to see some newcomers trying the sport for the first time, with lots of expert help. Since the full ARDF course was relatively short, there were only two beginner transmitters --- just enough to give some practice to the first-timers and warm-up for the others. To nobody's surprise, the best time on the full course was turned in by Jay Hennigan WB6RDV, who has medaled at the USA ARDF Championships and finished 16th on two meters in the World Championships last September. Jay made a trip around the lake to bag four of the five foxes in 37:20. Unfortunately, due to a command error (oops!), the fox #5 had been accidentally silenced when he got close to it. So Jay headed for the finish and then decided to go out again to find it when it was restored. He was given a fresh start coincident with #1 going on, as all others were. He got #5 and returned in 4:57, which means that he found it and was back at the finish before it cycled off!

Wireless Internet
by Bill Talanian 08 Jan '07

08 Jan '07

8 January 2007 To: Interested parties From: Bill Talanian Subject: Wireless Internet, An analysis The downtown site at La Vigia Hill is receiving interest by a company that is proposing to install a Wireless Internet at this location. The location has been surveyed by a consulting and engineering firm. The Wireless Internet is competitive to what is provided by Cox Cable and present DSL systems. The present configuration of their system will consist of 22 selected locations in Santa Barbara with the back-haul going to the cellular site near the county dump behind the Sheriff's Station. The company proposing this system is called Clearwire. The founder is Craig McCaw (Wendy's ex) who originally was successful with creating Cellular One. Cellular One was the original cellular company at La Vigia Hill. It is now called Cingular after McCaw sold his interest to AT&T. Clearwire proposes to use the present Cingular Tower for their antennas. Their equipment as I understand it is one footprint and 3 ft in height. The Club's effort in recent months has expanded our use of the unlicensed 2.4 GHz band for point-to-point linking and access to the Internet on the local DSL line. SBARC presently operates in the 2.4 GHz band to/from Diablo and QTH of N6TVE. Our future plan is to route the Diablo WebCam stream to UCSB. In addition, several other experimental proposals are on tap to use this spectrum for yet to be specified ARES use. Clearwire wireless technology uses OFDM transmission protocol, featuring a design standard that includes secure wireless data transmission. Wi-Fi operates on unlicensed 2.4GHz frequencies, making it vulnerable to scanning and packet interception. Clearwire operates at licensed 2.5GHz frequencies. Technically I'm not so sure if SBARC's use of the 2.4 GHz spectrum will be totally free of local interference once Clearwire cranks up on 2.5 GHz. We all know what happens when stations in the near field soak up the ether bandwidth. As usual our relationship with the telecom industry has always been excellent and cooperative. Typically the hilltop rationale is, last man in must ensure that mutual problems are not being generated. We hope not! Our local experience at La Vigia with DSL Internet access tells us that bandwidth limitations are hampering our present operations. Contact was made with Cox Cable to see if they could run a cable line to our equipment shed. Cox responded with a cost proposal and discount structure for a 501 group such as SBARC. The installation cost was fair but not exactly cheap. SBARC is still exploring this option. Of course one could always say that SBARC should install a Wireless Internet box and access the Internet via Clearwire. For sure there would be no excuse for not making it to their wireless system. Clearwire is still a proposal and it will be a year or more before anything happens due to permitting and local site agreements. The Cox Cable alternative is ready and available. If you run Clearwire on your browser you will get an idea of Clearwire and their movement in this direction. Here is a CNN clip. Bill Talanian Clearwire founder Craig McCaw shakes up the telecom industry again. <http://money.cnn.com/2006/09/15/technology/disruptors_clearwire.biz2//magaz…> Business 2.0 Magazine By <mailto:ESchonfeld@business2.com>Erick Schonfeld and Jeanette Borzo, Business 2.0 September 21 2006: 10:47 AM EDT SAN FRANCISCO (Business 2.0 Magazine) -- The Disruptor: Clearwire The Innovation: National Wi-Max broadband wireless service Clearwire Headquarters: Kirkland, Wash. Co-CEOs: Craig McCaw, Benjamin Wolff Founded: 2003 Employees: approx. 1,000 Key stat: 99,500 worldwide subscribers CNN and Business 2.0 look at ways to improve technology in terms of engine and fuel efficiency. (September 20) Play video The Disrupted: Telecom and cable companies It's almost a given these days that Clearwire, the Wi-Max wireless network founded by cellular pioneer Craig McCaw, will shake up the wireless broadband sector. "If anyone is going to do it, it's going to be Clearwire," says Joe Laszlo, a senior broadband analyst at JupiterResearch in New York. "They've got the best technology, great financing, and a lock on nationwide spectrum." The only real question seems to be how deep into the telecom establishment the shock waves from McCaw's latest bit of disruption will penetrate. Clearwire's initial goal is to create a nationwide broadband wireless network based on Wi-Max, a more powerful relative of Wi-Fi technology. Because Wi-Max infrastructure is much cheaper to build and maintain than traditional networks, some analysts think Clearwire will be able to seriously undercut the broadband prices of <http://money.cnn.com/quote/quote.html?symb=CMCSA>Comcast (<http://money.cnn.com/quote/chart/chart.html?symb=CMCSA>Charts), <http://money.cnn.com/quote/quote.html?symb=VZ>Verizon (<http://money.cnn.com/quote/chart/chart.html?symb=VZ>Charts), and their ilk. But the threat posed by McCaw's strategy could be much greater than just price pressure. Clearwire's approach could put in jeopardy the billions of dollars that telecoms and cable operators are pouring into upgrading their existing broadband networks. And in theory at least, Clearwire could eventually offer the cutting-edge services that telecoms and cable companies are angling for -- Web-based TV, movies on phones, VOIP calls, and the like. Clearwire is already offering VOIP phone service to 13 markets, and some expect the startup to partner with mobile-phone, IPTV, or satellite-TV companies to further expand its range of services. (Full disclosure: AOL, owned by the parent company of Business 2.0, is a reseller of Clearwire Wi-Max service.) "Filling a need that others aren't addressing has always been a focus of the McCaw companies," says McCaw's co-chief executive officer, Ben Wolff. "We are creating a brand-new category." Certainly, the press-shy McCaw knows a thing or two about shaping disruptive networks. He began building the country's first national cellular network in the early 1980s, eventually selling it to AT&T for $11.5 billion. With Clearwire, McCaw has moved on to Wi-Max. Wi-Max has big technical advantages over other fast pipes, particularly Wi-Fi. Unlike Wi-Fi, it operates on a licensed spectrum, making the service far more reliable. The range of Wi-Fi signals is measured in hundreds of feet; Wi-Max's range is measured in miles. Clearwire already offers basic Wi-Max broadband service in Brussels, Dublin, and 27 U.S. metropolitan markets covering more than 200 cities and towns. Its network had 100,000 subscribers at the end of March. (The company won't say how many new subscribers it has added since then or disclose financial details.) Clearwire also has made the installation process, often a painful hassle for Wi-Fi users, consumer-friendly with Wi-Max. A customer plugs a paperback-size modem into a power source and into a computer (via Ethernet) and the network is good to go. "It's a very simple process for a consumer to get up and running," says Jupiter's Laszlo. Clearwire has challengers, notably <http://money.cnn.com/quote/quote.html?symb=S>Sprint (<http://money.cnn.com/quote/chart/chart.html?symb=S>Charts), which expects to spend as much as $3 billion in the next two years building a rival Wi-Max network and currently owns more spectrum than Clearwire. But Clearwire has powerful backers: In July, <http://money.cnn.com/quote/quote.html?symb=INTC>Intel (<http://money.cnn.com/quote/chart/chart.html?symb=INTC>Charts) and <http://money.cnn.com/quote/quote.html?symb=MOT>Motorola (<http://money.cnn.com/quote/chart/chart.html?symb=MOT>Charts) pumped $900 million into the company, a measure of their faith in McCaw's approach -- and of their hunger to sell chips and other gear that make Wi-Max work if it becomes a mainstream service. Perhaps most important, Clearwire has McCaw. "Disruptive," says Rich Begert, CEO of Wireless Services and a former McCaw executive, "is the best way to describe Craig." **************************

ARDF at Lake Carnaros Saturday, 1/6/2007
by Marvin Johnston 03 Jan '07

03 Jan '07

Hi everyone, Someone asked me a question about going out as a team. Since this is a training or practice event, it is fine (and even encouraged) to go out as a team. If you have kids or grandkids, this would be a great opportunity to do something together. There will be five transmitters to find, and you or your team will be provided with a detailed orienteering map of the area. Depending on how many transmitters you want to find, the course will range from about 1/2 mile to a little over 2 miles. Reservations are not needed, and the details are on the HomingIn website at http://www.homingin.com. We have a tradition in place where we go out to Sizzler's after the event is over and transmitters picked up (about 4:00PM) and everyone is welcome. Marvin
