Impulse

[] From left, sales staffers Lee Carlander and Tracy Green; Chris Rose, director of sales/marketing; and engineers Jay Hennigan and Jessie Bryan of Impulse Advanced Communications. MIKE ELIASON/NEWS-PRESS Local firm boosts business broadband By STEVE SINOVIC, NEWS-PRESS STAFF WRITER March 11, 2012 7:58 AM Impulse buying may be taking a whole new meaning for small business owners in Santa Barbara looking for faster broadband service. At a time when businesses depend on Internet access more than ever, Santa Barbara-based Impulse Advanced Communications is investing heavily to land new clients in the region or help current customers upgrade. Some of the growth is being funded by a loan of more than $1 million (and more to tap in a bigger line of credit) from Business First Bank to fund the rollout of new service between Carpinteria and Goleta. "It should help us get into double-digit growth," predicted Dave Clark, president of the company, in a recent interview the NEWS-PRESS, as he discussed strategies to expand the customer base. Mr. Clark, a UCSB psychology grad who later ran Circuit City's IT system, said his time with Impulse dates back to when the company was a dial-up Internet provider mostly serving home users. As the landscape changed and other providers jumped onto the consumer bandwagon, Impulse, which was founded in 1996, charted a niche as network specialists, working with large local employers such as Santa Barbara Bank & Trust and Deckers. Impulse seeks to differentiate itself by addressing service gaps not offered by the larger competitors, helping to tweak many aspects of a customer's network, including phones, routers and switches. Thanks to business loans, Impulse set in motion its next-generation network when it saw Internet options for businesses on the South Coast remaining narrow while demand for bandwidth was increasing. Business Internet access comes through three pipelines: coaxial cable, traditional copper wire and fiber optics. Cox Communications owns and controls the region's coaxial cable lines and Verizon stopped upgrading its copper lines and has been focusing more on its wireless business and building a residential television network in large markets. But Verizon's traditional copper lines, which are linked to virtually every business and home in the region, presented an opportunity to telecommunications carriers with the proper licenses. So, 18 months ago, Impulse received a license which allows it to use all of Verizon's copper wire between a customer's building and Impulse's equipment. Thanks to advances in technology, Impulse is able to deploy equipment that provides fast, high-quality Internet access using copper. All the copper wire between Ellwood and Carpinteria run to six central Verizon offices and Impulse has leased space in five of them. For obvious reasons, the wires are highly secure, with cameras and badges and series of "tough tests" to gain access. "We each have our own cage locked off," said sales director Chris Rose, referring to the place where all the connections occur. Technology advances mean higher speeds and reliability don't bring sticker shock to customers. "From a customer perspective, there is a slight increase in cost, but a significant increase in bandwidth," said Mr. Clark, who hopes to expand the business to points north and south as sales increase in its home base. The company's hometown roots make entry by competitors difficult, Mr. Rose said. "That's been our point of differentiation," he said. "The level of problem solving and accountability isn't always there with the larger" companies. Having a degree in computer science doesn't necessarily lead to work for Impulse. Someone with a general networking certificate from a community college can qualify for an entry-level position with the firm. "They start with customer support for a period of time, graduate and get promoted to network operations," said Mr. Clark of the career trajectory of many of the Impulse workforce, which now comprises 30 employees. Still, network and systems engineers are on staff to help technicians learn and understand current technology. The recent recession notwithstanding, businesses of all kinds cannot stint on connectivity. As the economy recovers, any down time or delays are deadly, especially for data-heavy companies like law firms, banks and accounting firms, and those selling products and services online. "The quality of the connection is critical as a business grows," said Mr. Clark. "It's not so much the size, but the reliability of the bandwidth," explained Mr. Clark. In terms of reliability, he suggests that some clients have "highly redundant" service, which means backing up data in server farms and in clouds. To serve its current and future customers, Impulse plans to hire 10-plus additional employees over the next 16 months. While targeting small to mid-size businesses with new products are a priority, big business isn't being ignored. "They still need some love," said Mr. Rose of the larger companies. email: ssinovic(a)newspress.com

Anyone have any experience using these BST capacitors for antenna tuning arrays, or tunable filters ? :-) neil KE6DCJ ======== Powering a 30V DAC from a 3V supply (CN0193) Analog Devices Model Number: CN0193 The circuit generates a high voltage signal that controls the capacitance of a BST (barium strontium titanate) capacitor.

Daily Nexus - Seybold (W6AMS)
by Bill Talanian 09 Mar '12

09 Mar '12

Daily Nexux A UC Santa Barbara Student-Run Publication SB Local Aids in Formation of Public Safety Network by <http://www.dailynexus.com/author/garciela-romero/>Garciela Romero March 9, 2012 Santa Barbara resident Andrew Seybold, the nations leading wireless communication consultant, collaborated with the Public Safety Alliance to include the public safety broadband provision in the Middle Class Tax Relief Act. The bill, signed into law by President Barack Obama on Feb. 22, extends current payroll tax reliefs and several key job initiatives and grants a portion of the national airwaves exclusively to public safety organizations. The legislation also sets aside $7 billion for the construction of a nationwide public safety broadband network for fire, law-enforcement and EMS departments around the country. According to Seybold, people using cell phones voice, text, picture and video capabilities at higher rates during a crisis often overwhelm their servers capacities. Public safety can not use the commercial networks AT&Ts, Verizons, Sprints or T-Mobiles because when there is a major emergency, those networks get overloaded and overcrowded, Seybold said. Theres no way that they have priority on the network. Seybold spoke with members of congress while campaigning with the PSA for a new approach to emergency communication. Although the initial federal funding is insufficient to create a full-scale nationwide network, Seybold said the project is progressing forward. The bill grants the creation of nationwide piece of spectrum, which is dedicated to public safety, Seybold said. It is going to build a nationwide network and it is going to accomplish many things. It is going to give sight to first responders who are essentially blind today because all they have is voice. Seybold said recent national crises prompted the establishment of a new broadcast system for first responders. A couple months ago there was an earthquake in the Washington D.C. area all up and down the East coast. On the commercial networks nobody could make a phone call or send data for multiple hours, Seybold said. If public safety had been using that radio spectrum to do their broadband communications, it would have not been available to them. Therefore, we needed our own spectrum. Firefighters will have access to a buildings structural information and its contents under the new system, according to Seybold. They dont know what is there, they dont know if it is a laboratory, if there are dangerous chemical or poisonous gases, Seybold said. With broadband as they are going to the scene they will get transmitted to them the blueprints of the building and any locations with hazardous material, or anything like that, so that they can be prepared when they get there.

AndySeybold (W6AMS) Recognized for service

Andy Seybold, W6AMS, recognized by Public Safety Alliance PSA celebrates broadband-network victory Mar 6, 2012 10:55 AM, By Donny Jackson (donald.jackson(a)penton.com) BROOMFIELD, COLO. In a room filled with smiles, plaudits and good-natured ribbing, many key members of the public-safety community last night celebrated its unlikely political victory that resulted a new law that secured the 700 MHz D Block spectrum for first responders and $7 billion in funding to help pay for a nationwide broadband network. Hosted by the <http://psafirst.org>Public Safety Alliance on the eve of the <http://www.pscr.gov/>Public Safety Communications Research (PSCR) meeting, PSA officials reflected on the varied support needed to make the much-anticipated broadband legislation a reality. "When we first started this endeavor, they told us that it couldn't be done," said PSA spokesman Chris Moore, police chief in San Jose, Calif. "Public safety was told, 'You will not get the D Block, and forget about funding.' "Everybody came together, because it was the right thing to do, and it was the right time not only for public safety but for the American public. Were not a special interest; we're here to protect the American public. And that's what we're were able to do, with everybody in this room coming together." Former <http://iafc.org>International Association of Fire Chiefs President Jeff Johnson echoed this sentiment. "Nothing in my 32 years of service ... is greater that what we've achieved here tonight. Nothing will change the business more than this. I hope you all will take a moment to take satisfaction in what you have done." Moore expressed public safety's appreciation for the support it received from key lawmakers like Sen. Jay Rockefeller (D-W.Va.) and Rep. Peter King (R-N.Y.). Similar plaudits were given to President Barack Obama, Vice President Joe Biden a key figure in this episode, according to many sources and others in the current administration. "For the first time ever, public safety came together on an issue and stayed united for over three years. For the first time in my memory, the federal agencies that are responsible for public safety the DOJ, DHS and Commerce came together. Anna Gomez [deputy assistant secretary for communications and information and deputy administrator of the <http://ntia.doc.gov>National Telecommunications and Information Administration] thanks for bringing everyone together and making that happen." Moore also acknowledged the support from key industry players most notably, Verizon, AT&T, Motorola and Harris that provided key funding and support for public safety on Capitol Hill. All of the key public-safety organizations were applauded for their efforts, particularly the <http://apco911.org>Association of Public-Safety Communications Officials (APCO). "It's tough enough just to get public safety all in a room," Moore said. "It's even harder to try to get us to agree on anything. Like Jeff Johnson said, 'It's like cats and dogs sleeping together. It's not natural.' But it happened." Six critical players Johnson, former APCO president Richard Mirgon, New York City Police Department Deputy Chief Charles Dowd, Public Safety Spectrum Trust (PSST) Chairman Harlin McEwen, Seattle Chief Technology Officer Bill Schrier, and mobile wireless consultant Andrew Seybold were singled out for their significant contributions during the lengthy process by Moore. To conclude the event, Johnson credited Moore for his role in helping to develop consensus throughout the public-safety community on this issue. "This room is filled with different opinions, and this issue is filled with different perspectives. If we did not have a leader that understood how to balance it all, ... we would have failed, he said. "As much as it pains me as a firefighter to admit that a cop was the guy who brought people together, I'm asking you for one moment of your attention to recognize the leadership of Chris Moore. The guy is spectacular ... he is awesome."

[ardf-socal] Reminder of ARDF at Santa Fe Dam on Sunday
by Marvin Johnston 09 Mar '12

09 Mar '12

Remember to set your clock ahead one hour Saturday night for Daylight Savings Time so you'll be on time for the ARDF session at Santa Fe Dam on this Sunday, March 11. The weather forecast is favorable, so make plans to attend. This event is a mix-in with a classic orienteering session of the Los Angeles Orienteering Club (LAOC). That's why it's on Sunday, not Saturday. The transmitter hunt will commence at 10 AM. Hunters may start out on the courses at any time until 12 noon. Courses close at 2:30 PM. Orienteering flags and electronic scoring will be used at each transmitter. If you have an "e-stick," be sure to bring it. For non-LAOC members, there will be a $12 donation for individuals ($14 for small groups) to cover expenses related to the use of Los Angeles Orienteering Club's e-punch equipment and maps. For LAOC members, the donation is $7 individual and $9 group. Santa Fe Dam Recreational Area is in the city of Irwindale near the intersection of the 605 and 210 freeways. From 605 northbound, take the Live Oak Avenue exit and go east. From 605 southbound, take Arrow Highway exit and go east. In both cases, you will merge into Arrow Highway westbound. The park entrance will be on your left, opposite Azusa Canyon Road. Alternately, from the 210 freeway, exit at Irwindale Avenue, go south to Arrow Highway, turn right (west) and look for the park entrance on your right opposite Azusa Canyon Road. Vehicular entrance and parking costs $10 per vehicle. After the entry kiosk, continue to the first stop sign, go straight through the intersection and then turn left into the parking lot at the end of the short road. Talk-in is on 146.52 MHz simplex. A map to the park is at www.homingin.com. If you have questions, send e-mail to homingin(a)aol.com. The park's business office will not have updated information about this event. 73, Joe Moell K0OV homingin(a)aol.com www.homingin.com
