BST Capacitors
by neils 13 Mar '12

13 Mar '12

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. The capacitance of a BST capacitor can be altered by applying a voltage of between 0 V and 30 V to the correct terminal. This changes the thickness of the dielectric and, hence, the capacitance. BSTs are often used for tuning antenna arrays or tunable filters. Clearly, there is an advantage in being able to tune these applications for example, compensating for component tolerance errors. This reference circuit has been engineered and tested for quick and easy system integration. Design note here: http://www.analog.com/static/imported-files/circuit_notes/CN0193.pdf

Daily Nexus - Seybold (W6AMS)
by Bill Talanian 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 08 Mar '12

08 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

Seybold (W6AMS) and Public Safety

<http://www.noozhawk.com/noozhawk/print/030112_public_safety//> Noozhawk.com Santa Barbara & Goleta Local News [] PRINT THIS PAGE Expert Andy Seybold Plays Role in Creation of National Public Safety Communications Network http://www.noozhawk.com/noozhawk/article/030112_public_safety/ By Alex Kacik, Noozhawk Business Writer | <http://twitter.com/NoozhawkBiz>@NoozhawkBiz Andy Seybold, a Santa Barbara mobile computing consultant and f Andy Seybold, a Santa Barbara mobile computing consultant and founder of Andrew Seybold Inc., worked with the Public Safety Alliance to get the public safety section of the federal tax bill through Congress. (Alex Kacik / Noozhawk photo) Federal tax bill signed by Obama includes a provision that could open new doors for the way first responders receive information When <http://www.whitehouse.gov/administration/president-obama>President Barack Obama signed last weeks tax bill, he did more than extend a payroll tax deduction and unemployment benefits. The legislation also includes a section that could revolutionize how public safety officials communicate, according to Santa Barbara technology expert <http://andrewseybold.com/company/about-andrew-seybold>Andy Seybold. I look at fire and police agencies that only have voice communication as blind, Seybold said. We will give them eyes. He said its a communication solution that could have aided first responders during Santa Barbaras <http://www.fire.ca.gov/index_incidents_Tea.php>Tea Fire in 2008. During the wildfire, residents overloaded commercial networks, forcing public safety officials to rely on a segmented network that prevented certain agencies from communicating with each other. When there are major disasters, commercial networks get jammed and public safety cant count on it, said Seybold, a mobile computing consultant and founder of <http://andrewseybold.com>Andrew Seybold Inc. Public safety needs their own piece of spectrum. Two and a half years ago, Seybold joined the <http://www.psafirst.org/>Public Safety Alliance, which lobbied <http://en.wikipedia.org/wiki/United_States_Congress>Congress to reallocate a piece of spectrum for public safetys nationwide interoperable network for solely its own use. The alliance has opened new opportunities, according to <http://www.sheriffs.org/>National Sheriffs Association president Paul Fitzgerald. Ive been in law enforcement for more than 36 years, and Ive never seen an issue that united public safety officials as this has, he said. But some argued against the initiative. First, a public safety network requires higher standards, and dissenters thought the cost was too high. Therefore, they said it would be more cost effective to auction off the spectrum for commercial use. Second, some didnt understand why public safety couldnt share spectrum with commercial networks. We got a very cold reception, Seybold said. They are worried about the national debt and are looking at the fact that this spectrum could be auctioned for $3 billion that could go toward national debt. But if you put in perspective that our national debt grows at $4.5 billion a day, what were talking about is less than one day of national debt. So our argument was, this is really an investment in public safety. During the <http://en.wikipedia.org/wiki/September_11_attacks>9/11 terrorist attacks and <http://en.wikipedia.org/wiki/Hurricane_Katrina>Hurricane Katrina, one of the biggest problems was that police officers couldnt talk with firefighters because public safety spectrum is spread out all over, Seybold said. But a nationwide public safety broadband network would go beyond efficient voice communication, he said. It would provide the video tools and interconnectivity that most people have with their smartphones. For instance, first responders would be able to immediately receive blueprints of virtually any building, dispatch could stream live footage of a developing scene through a dashboard camera, and paramedics could electronically send the results of an ultrasound so doctors could start treating a victim. If we have all these tools in front of us, we will catch more people and be safer, Seybold said. Retired Ithaca, N.Y., <http://www.govtech.com/e-government/Harlin-McEwen-chairman-Public-Safety-Sp…>Police Chief Harlin McEwen, chairman of the <http://www.psst.org>Public Safety Spectrum Trust, said sometimes speed and efficiency mean the difference between life and death. These are the kinds of things that happened, in my career or today, because of the lack of ability to transmit data in a way that is fast and reliable with the bandwidth that is necessary, McEwen said. It would also give rural areas access to broadband services that they never previously had exposure to, he said. But do the benefits outweigh the costs when the nation is trillions of dollars in debt? Thats the important question if it is a smart investment at this time, Santa Barbara entrepreneur and <http://www.noospheric.com>Noospheric founder Jacques Habra said. What if theres a major earthquake, and whats the cost for not having a (nationwide) system? Look at the potential human loss. America is one of the top nations that puts human safety first. Now, McEwen said, the government will set up the First Responder Network Authority in the next six months that will serve as the governing board. Once we have a reliable service to get information quickly, he said, it will save lives and make work more efficient. <http://www.noozhawk.com>Noozhawk business writer Alex Kacik can be reached at <mailto:akacik@noozhawk.com>akacik(a)noozhawk.com .

[ardf-socal] Next ARDF at Santa Fe Dam on March 11
by Marvin Johnston 29 Feb '12

29 Feb '12

Sunday, March 11 is the date of the next southern California on-foot transmitter hunting session. It will be at the Santa Fe Dam Recreational Area in Irwindale and will feature a five-transmitter radio-orienteering course of low-to-moderate difficulty. All ages are welcome, so bring the family. A ham radio license is not required. Experts will be on hand to teach you the basic techniques of on-foot radio direction-finding (RDF). 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. Course-setter will be Marvin Johnston KE6HTS. Because Marvin has duties for LAOC during this event, there will not be an antenna and attenuator building workshop. However, if you want to pick up a kit for antenna and/or attenuator to take home, contact Marvin by e-mail (marvin(a)west.net) and he will bring it to the park with him. 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.
