1940 radio shell for display
by Dorothy Oksner 03 Apr '12

03 Apr '12

Santa Barbara County Genealogical Society is looking for a Radio from 1940 to borrow for their April 14 & 15 Open House, to be displayed along with other 1940 memorabilia, in celebration of the release of the 1940 Census. All the better if it's only a shell where an iPod or iPhone can be hidden playing music from the 1930s and 1940. Contact Dorothy Oksner ox(a)silcom.com 684-3048 KJ6UGL Dorothy sbgen.org

Upcoming CERT Training
by Rod Fritz 01 Apr '12

01 Apr '12

Hello SBARC Members and Friends, A few months ago, a few SBARC members attended the CERT Training (see attachments) and we found it very well-done and worthwhile. Basically, it prepares you to assist your family and neighbors during the first 72 hours of a major disaster when local services may not be readily available. Although, the courses listed here are held in the UCSB area, you will be welcome if you’re an outsider as many of us were. If you’re interested, I suggest contacting Jim Caesar by email (see the “From” line below) and do yourself, your family and your community a big favor by completing the course.

Ham Radio Now
by Marvin Johnston 29 Mar '12

29 Mar '12

Those of you who were at the last SBARC club meeting saw a DVD on ARDF by Gary Pearce, KN4AQ. He has some other information available that some of you might find interesting: HAM RADIO NOW - Episode Six: New Ham Band! The recently concluded WRC-2012 in Geneva produced a new ham band in the MF range - 472-479 kHz. Last Monday, Cliff W4FT and I traveled to Washington DC to talk to Brennan Price N4QX, ARRL's Chief Technology Officer and part of the team that the League send to Geneva. Brennan gave us all the details and background, and it's all on-line, waiting for you at www.HamRadioNow.TV. And we didn't send an email about it, but Episode 5 is there, too, on the upcoming QST: Digital Edition. ARRL's marketing manager Bob Inderbitzen NQ1R gives us the details on that. Starting with the June issue, League members will be able to read/download QST on-line. Ham Radio Now is viewer-supported. If you like what you see, you can contribute at www.ARVN.tv — whatever you think it's worth to you. Thanks to everyone who has contributed so far! 73, Gary KN4AQ ARVN: Amateur Radio//Video News Ham Radio Now.TV Gary Pearce KN4AQ 508 Spencer Crest Ct.

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
