In order to learn much about electronics, the best way is to have circuits to assemble. For your electronics project, there may be a necessity for particular instruments and different parts. Circuit board is one of the first things you should be considering. Circuit boards are being used to put all the connection and assembly of the circuits. Circuit boards are classified into 3 major types. If there is no need to solder the circuits then you can just use the breadboard. You must have a small type of the snipe nose as it is to be used for bending the lead and also to hold parts for soldering. You might need an electrical drill too for your electronic projects work requirements. Whenever electronics could be your hobby or if you’re a pc specialist, be certain to understand about the Resistor Color Code and also utilize them. Lots of individuals opt to use the 555 timer since it is much advantageous as well as multipurpose. Diode which is being used to alter voltage is a zener diode and it’s also a very prevalent component in consumer electronics. For logical procedures that are to be handled, one could utilize logic gates which actually are the necessity for electronic digital applications. EL wire has the ability to emit diverse colored lights and can be employed very much like an everyday wire but with an extra light effect. Varistor is now being utilized in various areas of home equipment to safeguard it during excess voltage. To stop certain parts of electronic devices to get too hot, thermal paste will be used to guarantee that it stays cooler.

The NPN transistor is truly a modernized variant for electron tubes utilized on numerous homemade projects on electronics. The disco lights can be crafted a lot more elaboratey with the help of not just lights but sounds too with the aid of PIC programmer. A lot of people find it so much fun to learn and work on electronics. Hobbyists like to follow certain circuit designs for their own developed electronic products. You dont need to have a degree for electronics to create your own products on circuitry. Amateur hobbyists fond of electronics do it for their own joy and not to sell it. Instruments that are powered with radio control is a fun hobby for a lot of people. Many new generations nowadays enjoy the complexity of programming and consider it as a fun hobby. It is fun to make and earn from your hobby which is why many electronics hobbyists also learn about electronics repair. If you know how to repair the gadgets you have at home then you can save a lot of money. If you have the knowledge on how to do electronic repairs then you can save a lot by repairing the appliances you have at home. The devices on electronics are made to be sensitive in the function it was made for. If you are still a newbie to electronics then the first thing you need to do is do a lot of research. Electronic devices has components that can be harmful o make sure you know which ones are. It is necessary that the devices needed for electronic repairing is accessible straight away.

The-News-Leader.com – Some old time tales about telling time

1329909501 82 The News Leader.com   Some old time tales about telling time

February will have 29 days this year because it’s leap year. The extra day will be added because the time it takes for our earth to make one revolution around the sun is not exactly the same as our 365 day calendar year.

Even an extra day every four years doesn’t make up for the difference and this year we will add an extra one second — a “leap second” — to keep our calendars on time.

A long time ago, the calendar was so far off that they had to just skip about 11 days to get it back to where it should be.

That extra day has been celebrated by giving women an opportunity, on that special day, to propose to their future husbands. Readers may remember Sadie Hawkins Day!

Anyone born on the 29th of February has a birthday only every four years.

For millions of years, people did not need clocks or calendars. They began their days at sunrise and quit working when it got too dark to see what they were doing, at sunset. Farmers would tell time by the ringing of the Angelus bells in their local church at 6 a.m., noon, and 6 p.m.

When pocket watches became available, a gold watch was a status symbol. In their homeland, most working class people were not allowed to own gold. I like the story of the immigrant who bought a fancy gold watch with a heavy gold chain.

When his friend asked about it, he proudly showed it off. Was it expensive? Yes! Did it keep accurate time? Right on the dot. When asked, “What time is it now?” he showed it to his friend and said, “There it is!” and his friend responded, “Dog-gone if it aint!”

There was an attempt a while back to change our calendar from 12 months to 13 months. Every month would have 28 days and at the end of the year there would be an extra day like we have this year. With that calendar, the first of every month would be on Sunday, and all holidays would be on weekends, either Friday or Monday.

I think the biggest problem with that scheme would be finding a name for the extra month.

I haven”t heard this joke in a long time, but here it is: What is the shortest measured unit of time? It’s the time that elapses between when the traffic light turns green to when the driver behind you blows his horn.

Here’s another one. How much time elapses from two to two to two two? That’s not a typo. If you read it correctly it says, from two minutes to two until two minutes after two. Elapsed time, four minutes.

My favorite time joke is about the man who was asking a friend for advice about improving his relationship with his girlfriend. He wasn’t very good with words, especially romantic words spoken to a “girl.”

This is what the friend suggested. Tell her, “Darling dearest, when I gaze into your your baby blue eyes, and I see how they light up your flawless face, all time stands still.”

The next day the man showed up with a black eye. What happened? Well, he explained how he tried to remember those flowery words, but forgot the exact wording so he did the best he could. What did he really say? “Baby, your face would stop a clock!” Close, but not close enough.

When we were kids, we knew the three fastest means of communication, to get a message from one place to another in the shortest time, were “telephone, telegraph and tellawoman.” That was in the days when the telephone was a new invention and women were on friendly speaking terms with their neighbors.

Exchanging the latest gossip over the back fence or while in line at the butcher shop, was the equivalent of today’s electronic “social media.”

When daylight saving time was a new idea, a woman complained that in the fall when the clocks were changed and it got dark an hour earlier, the loss of an hour of daylight was preventing her tomatoes from ripening.

I don’t like the idea of changing the clocks twice a year.

I don’t know if it still happens, but there used to be places that did not switch and sometimes the boundary line between “fast time and slow time” ran right through a house.

Those people would have different time in one part of the house than in another.

Most people are familiar with the name “Big Ben.” Some think it is the clock in the tower of London. Actually it’s the name of the big bell in the tower. When short wave radio was new, it was quite a thrill to tune in and actually hear Big Ben ring.

There was an early television childrens program that began with the question, “What time is it?” and all the little kids would say, “It’s Howdy Doody Time.”

You don't need to pay through the nose for ham radio. This is a humdrum way for obtaining shortwave radio. Serious ham enthusiasts usually move up to beam antennas to enjoy better transmission and reception of signals. Getting licensed is the next hurtle. It's only going to help out their discussion more in the long run. However, there is not much information available for the solar ham radio enthusiast. You want a plan for hams radio. Therefore, in the case of your FRS radio instead of having a mere 14 channels to choose from by using these sub-channels you can effectively have 532 available channels. 10 Meter Ham Radio To technician-class licensees and higher, two bands are available that allow for communication between ham radio operators: the 2-meter and 10-meter bands. 5. If you want to try and reach as far as outer space from the comfort of home, try getting involved with HAM radio.What is ham radio Ham radios or amateur radios are used by many individuals especially amateurs who use various radio gears to communicate with other amateurs as a recreational practice, or training, or public services.

Business & Technology

1329908297 67 Business & Technology

SAN JOSE, Calif. — Google is in the midst of more than $120 million in construction projects at its Mountain View, Calif., headquarters, including work on a series of new or previously secret hardware-testing labs that hint at the Internet giant’s expanding interest in crafting consumer devices like its rivals Apple and Microsoft.

Among the projects, revealed by a review of public records by the Mercury News, are a lab to test a new consumer product under the brand name “@home” that will wirelessly stream music or data to other household devices, apparently similar to a prototype home-audio service Google demonstrated publicly last year.

And, most intriguingly, Google is modifying a lab for a project enigmatically named “Project X,” which appears to involve precision optical technology and could be part of the secret technology projects Google co-founder Sergey Brin is heading.

The highest-profile project will be a “Google Experience Center” under construction at the core of the Googleplex. The 120,000-square-foot center will be a kind of private museum for Google’s most important clients and partners, where the company plans “to share visionary ideas, and explore new ways of working” with up to 900 VIPs and other important guests, according to documents Google filed with the city of Mountain View.

“The Experience Center would not typically be open to the public — consisting of invited groups, and guests whose interests will be as vast as Google’s range of products, and often confidential,” Andrew Burnett, an architect working on the project, explained in a letter late last year to Mountain View officials.

“Therefore, the Experience Center must also operate somewhat like a museum, exhibit or mercantile space allowing flexibility in the exhibits so that as Google’s products and needs change, the space can adapt.”

As Google becomes increasingly focused on selling its products to other companies, schools and government agencies, and developing consumer devices in addition to the Internet-based software that built its brand, facilities like the Experience Center and the new hardware labs illustrate a kind of rite of passage, said veteran Silicon Valley technology analyst Rob Enderle.

Google is joining a club that includes companies like Microsoft, Hewlett-Packard, Oracle, Boeing and IBM that have dedicated customer-demonstration facilities to showcase their products and technology to potential buyers, analysts and other important partners.

“It really becomes the showcase for the company,” Enderle said. “They are designed to impress. They are part of the sales process. The purpose is, you walk in and you have an ‘oh, wow’ moment.”

Across the Googleplex, construction crews have been busy in recent months working on about 800,000 square feet of renovations, city records show. With Google completing the biggest hiring year in the company’s history in 2011, many of those projects are employee amenities such as cafeterias, employee showers or charging stations for electric cars.

Google declined to say much about the Experience Center or to discuss its new hardware-testing labs or the mysterious Project X.

“Just as we continuously work to improve our products, it’s important to iterate on our work space to keep us productive,” the company said in a written statement provided by a spokesman. “That’s why we are adding additional meeting and work space to our campus in Mountain View.”

Retrofitting the campus

But with regulators signing off on Google’s $12.5 billion purchase of smartphone and tablet maker Motorola Mobility, the company also appears to be retrofitting its campus for a future where hardware is a more important part of its product offerings.

At 1600 Shoreline Blvd., for example, the company is building a lab that screens out radio frequency signals for a division labeled “Google/@home” to test new wireless consumer technology. Elsewhere on campus, it is building thermal and anechoic chambers that can be used for things like testing antennas’ radiation patterns.

The Google/@home “RF screen room will be used to test the Wi-Fi performance and development of a consumer product,” a Google real-estate official, Lewis Darrow, said in a letter to the city last year. The Wall Street Journal said recently that Google could launch a wireless home audio product later this year.

Project X, which occupies a space with blacked-out windows at a central location of the Googleplex, includes the use of rare gases like argon, a plasma cleaner that can scrub materials of contaminants, and arcane optical-coating technology, city records show.

While the purpose of Project X is unclear, Brin since last year has been focusing on a list of secret projects at the company, including its efforts to develop a driverless car.

Apple and Microsoft have extensive hardware-testing facilities on their campuses, as they design and develop products like the iPhone or the Xbox gaming system, Enderle said. Like the Experience Center, those testing facilities can also be part of the sales process, allowing Google to demonstrate new products.

“If you keep it close to the executive briefing center, you can bring in (manufacturing partners) or large customers, show them the testing as its going on, make them more comfortable with that product,” he said.

(The car body serves that purpose during mobile operations.) It's a nifty operation, and allows me to chat with folks in the Milwaukee area via local repeaters. If they do know they can do it then they are only ham radio to other nonprofessionals but they are never ham radio. 3)Verify the location of any utility lines at the selected location to the depth of the foundation required by the manufacturer's specifications. Lastly, do have some patience. That has woven itself within our conversation. Don't transmit if your license has expired even if you have applied for renewal. There are only a few basic things that you would need in order to get started.

Our View: Transparency and Pasadena police

1329905897 73 Our View: Transparency and Pasadena policeWE recently noted – OK, laid into – the two-facedness with which the largest municipal police department in our area deals with information that either used to be public or is made public by every other agency in the region.

The Pasadena Police Department has long maintained its commitment to “transparency” in the information it provides to citizens. But saying and doing are unfortunately two

separate matters.

We noted that for 80 years newsrooms in the San Gabriel Valley have been able to listen into the PPD’s radio traffic, as has anyone in the public who buys a scanner with the police frequencies. It’s not just the Pasadena department whose radio has been on the airwaves – it’s every department, plus the county Sheriff’s Department, in the region.

Now Pasadena, in meeting the federal mandate for digital rather than analog radio – born of transmission and reception problems in the Sept. 11 attacks on the World Trade Center – has met that obligation early, which is fine. But there was no mandate to encrypt – to make what has been hearable for eight decades unhearable without an unscrambler – that radio traffic. While the opposite of a crime wave is happily under way, PPD brass has chosen to encrypt its radio transmissions, though, claiming that it had to do so in order to keep vital information away from criminals.

Criminals who have been able to listen in for those 80 years, and suddenly it’s a problem?

On the other hand, we have no criminals in the newsroom. Surely, Pasadena would allow us to buy one of its decoders so we could continue to hear police activity in the city, and cover it. Sadly and inexplicably for the public’s right to know, Pasadena Police Chief Phil Sanchez denied that simple request.

Go ahead, file a Freedom of Information Act request for the radio traffic, then, the department suggested.

So we did. Then, again

inexplicably, the police changed their tune. They gave us a “call log” – whether it’s expurgated or not is impossible to tell – listing “loud party” calls for service and drunken-driving arrests over a week. That’s not at all what we asked for – or what the department said it would give. Now, it turns out, the PPD is going back on its word because it decided there is an “investigative exemption” that

prevents us from hearing or reading what we have always had access to.

Again, this is the department that claims it is

“thoroughly interested in transparency.” It is also one of the few police departments in Southern California that refuses to release mug shots of the people it arrests. Where’s the transparency there? For what purpose is this secrecy about suspects arrested? As soon as the Sheriff’s Department arrests someone, it makes the mug available, for instance. Why not Pasadena?

The department says it is studying options on the radio question – for instance, putting a half-hour delay on the transmissions and then letting us listen in, with half a newsroom ear, until something big breaks, as we always have. We’re certainly willing to talk about that one. We’re more interested in seeing actual transparency from the department that talks a good game and then blows a lot of obfuscatory smoke.

Ham Radio requires a licence?that is issued via the FCC( Federal Communications Commission)plus you have to pass an Exam to get issued with a licence and with?that not only issue you with a licence you also get a unique Callsign that is issued to you. Some people are interested in vanity call sign but it may be a little difficult to get the exact one you want. Some auto parts restoration cleansers, such as headlight restoration cleanser, will also work for removing scratches from your display screens. I had reviewed that I would like to ignore common sense. This is a concise summary of listen to ham radio as much as that will take several serious time from the beginning. 7)Join the nonprofit ARRL for $39 per year. This is one of the oldest ways to send voice communication across wires. This is how to check if your ham radio software free is working but also their normal service will be back momentarily. Ten-meter antennas can also be vertical (but will be much larger), but the configuration of those antennas more typically resembles that of a standard TV antenna.

As China clamps down, Tibet struggle grows radical

1329904718 47 As China clamps down, Tibet struggle grows radicalJIUHUANG FIRST VILLAGE, China —

Police don’t travel far to monitor the goings-on at the Gami Temple at the edge of the Tibetan plateau. The police station sits inside the monastery, just outside the gates to the main prayer hall.

Smothering security has become a fact of life in China’s Tibetan areas, from police stationed around monasteries to document checks at roadblocks. The heavy policing is driving some to radical acts to protest Chinese rule.

Most dramatically, at least 21 Tibetans have set themselves on fire over the past year. The immolations have set off a cycle of further repression that in turn has touched off large-scale protests in recent weeks. Some turned into deadly clashes between protesters and police.

Intense security is one reason Tibet’s exiled government in India called on Tibetans this year to shun celebrations for their traditional new year, which started Wednesday. Instead, Tibetans are urged to pray for those living under Chinese rule.

“The threats and Chinese policies and Chinese military in Tibet are becoming more abusive,” said Kanyag Tsering, a monk who left China 13 years ago for exile in India. He has become a channel for information from his home, Aba, a corner of Sichuan province where many of the immolations have occurred and which roadblocks and squads of riot and paramilitary police have effectively sealed off to foreigners.

One of the latest to self-immolate was an 18-year-old Buddhist monk in Aba whom Kanyag Tsering and another exiled monk said shouted blessings to their exiled leader, the Dalai Lama, and “Freedom for Tibet” when he lit himself on fire on Sunday.

In Lhasa, the capital of Chinese-controlled Tibet, fears ran high in recent days with a bigger police presence and officials calling on individual Tibetan homes, said the International Campaign for Tibet. Hundreds of Tibetans returning home were detained after attending teachings by the Dalai Lama in India, adding to anxieties, the Washington-based lobbying group said.

Photos of Lhasa dated Saturday and posted Tuesday on the blog of Tibetan writer Woeser showed columns of marching troops, an armored personnel carrier and police checking passengers on a bus.

“The continuing attack on the Dalai Lama and separatist troublemakers, greater surveillance of monasteries and nunneries, heavy military and security presence – all these mean that China is prepared to rule Tibetans through force,” said Dibyesh Anand of the University of Westminster in London. That determination, he said, is radicalizing Tibetans.

Behind the distress lies a fear that the Tibetan identity, so tied to their faith, is under threat. After more than a half-century of at times heavy-handed Chinese rule, Beijing is accelerating a policy of religious control, repression and economic inducements.

The program, affirmed at a top-level meeting in 2010, aims to extinguish Tibetans’ devotion to the Dalai Lama through forced denunciations, to deter protests through heavy policing and to raise living standards by pumping in investment that has brought double-digit growth rates but also Chinese migrants.

Asked about extra security precautions in Tibetan areas, Chinese Foreign Ministry spokesman Hong Lei praised the development that Chinese rule has brought to the region and lashed out at attempts to stir up unrest.

“Anybody’s attempt to incite a handful of monks in the Tibetan areas to take extreme action and undermine the stability of the Tibetan areas runs counter to the development of the Tibetan areas and the interest of the Tibetan people and does not enjoy popularity,” Hong said at a daily media briefing.

Monasteries, which for Tibetans are akin to universities, have become occupied ground, with police and officials moving in alongside monks.

At the Gami monastery complex, which hugs a wind-lashed hillside of pine at 10,500 feet (3,100 meters), police watched earlier this month as monks dressed in demon masks and colorful robes performed a purification dance for the new year before an audience of mostly well-dressed older farmers and herders. When thousands of Tibetans circled a sacred mountain behind the temple in another new year ritual, police watched the paths.

Checkpoints dot the roads, though the area is 300 miles (500 kilometers) to the northeast of the recent troubles. The temple itself does not belong to one of Tibetan Buddhism’s main schools, but is Bon, a pre-Buddhist sect, and the area has not had a history of large-scale demonstrations in recent decades.

Security weeds out foreign journalists, who were followed on a recent visit by uniformed and plainclothes security and ordered not to report in the area. But it’s also directed at Tibetans.

Monks in particular are being closely scrutinized and need to produce identification and sometimes letters of explanation to travel outside the immediate environs of their monasteries, according to people in Sichuan and overseas Tibet groups.

Kanyag Tsering decided to flee Kirti, Aba’s most prominent monastery, in 1998, when the first denunciation campaigns hit. This year, he said, several hundred political instructors and other officials moved into Kirti “to monitor everything that is going on” during an important festival. The number of monks, he said, has fallen to around 2,000, from more than 2,500.

Heavier security and tighter religious controls have seemed to fuel protests, rather than quell them. Robbie Barnett, a Tibet expert at Columbia University, said that security spending in Tibetan areas of Sichuan began soaring above that in non-Tibetan areas in 2006 and reached four times the average by 2009. Yet in 2008, the largest uprising against Chinese rule in 50 years occurred. Swarms of security came to the region and never left.

“Roughly speaking, China now seems to be facing increasingly cohesive discontent across an area twice the size of that it faced 10 or 15 years ago,” said Barnett.

Despite attempts by authorities to stifle information, including shutting some communities’ phone and Internet service, the immolators have become heroes. Accounts and snippets of their acts, usually captured by mobile phones, have circulated by Internet, instant messaging, homemade DVDs, foreign shortwave radio broadcasts and even posters.

Kanyag Tsering and other exiled activists said sometimes calls from public phones manage to get information of an immolation or a protest out quickly. More often, however, word seeps out days later, as people smuggle mobile phone images out of cordoned-off areas.

The government has signaled no intention of changing tacks. A senior official overseeing policy on Tibet, Vice Minister Zhu Weiqun of the United Front Department, called this month for full-throttle assimilation of minorities through migration, economic development and the spread of Mandarin.

“Our policy orientation should conform to this trend and deepen this trend so that it is irreversible,” Zhu wrote in the Study Times, the newspaper of the Communist Party’s top training academy.

Where You Can Find a Ham Radio For Sale That Will Fit Your Needs If you are looking for stores that have ham radio for sale signs, you may have to look a little harder because despite the fact that six million people across the world are amateur radio operators, they are not devices that you commonly run into. Reflector or Beam A beam or reflector antenna has two or more elements. Most of the time your best shot at finding a ham radio for sale that will work in your region is within your own region because they are being sold by other people who have used them in the same frequency zone.

The Associated Press: AP IMPACT: USAID contractor work in Cuba detailed

1329902298 87 The Associated Press: AP IMPACT: USAID contractor work in Cuba detailedAP IMPACT: USAID contractor work in Cuba detailed

WASHINGTON (AP) — Piece by piece, in backpacks and carry-on bags, American aid contractor Alan Gross made sure laptops, smartphones, hard drives and networking equipment were secreted into Cuba. The most sensitive item, according to official trip reports, was the last one: a specialized mobile phone chip that experts say is often used by the Pentagon and the CIA to make satellite signals virtually impossible to track.

The purpose, according to an Associated Press review of Gross’ reports, was to set up uncensored satellite Internet service for Cuba’s small Jewish community.

The operation was funded as democracy promotion for the U.S. Agency for International Development, established in 1961 to provide economic, development and humanitarian assistance around the world in support of U.S. foreign policy goals. Gross, however, identified himself as a member of a Jewish humanitarian group, not a representative of the U.S. government.

Cuban President Raul Castro called him a spy, and Gross was sentenced last March to 15 years in prison for seeking to “undermine the integrity and independence” of Cuba. U.S. officials say he did nothing wrong and was just carrying out the normal mission of USAID.

Gross said at his trial in Cuba that he was a “trusting fool” who was duped. But his trip reports indicate that he knew his activities were illegal in Cuba and that he worried about the danger, including possible expulsion.

One report says a community leader “made it abundantly clear that we are all ‘playing with fire.’”

Another time Gross said: “This is very risky business in no uncertain terms.”

And finally: “Detection of satellite signals will be catastrophic.”

The case has heightened frictions in the decades-long political struggle between the United States and its communist neighbor to the south, and raises questions about how far democracy-building programs have gone — and whether cloak-and-dagger work is better left to intelligence operatives.

Gross’ company, JBDC Inc., which specializes in setting up Internet access in remote locations like Iraq and Afghanistan, had been hired by Development Alternatives Inc., or DAI, of Bethesda, Maryland, which had a multimillion-dollar contract with USAID to break Cuba’s information blockade by “technological outreach through phone banks, satellite Internet and cell phones.”

USAID officials reviewed Gross’ trip reports and received regular briefings on his progress, according to DAI spokesman Steven O’Connor. The reports were made available to the AP by a person familiar with the case who insisted on anonymity because of the documents’ sensitivity.

The reports cover four visits over a five-month period in 2009. Another report, written by a representative of Gross’ company, covered his fifth and final trip, the one that ended with his arrest on Dec. 3, 2009.

Together, the reports detail the lengths to which Gross went to escape Cuban authorities’ detection.

To avoid airport scrutiny, Gross enlisted the help of other American Jews to bring in electronic equipment a piece at a time. He instructed his helpers to pack items, some of them banned in Cuba, in carry-on luggage, not checked bags.

He once drove seven hours after clearing security and customs rather than risk airport searches.

On his final trip, he brought in a “discreet” SIM card — or subscriber identity module card — intended to keep satellite phone transmissions from being pinpointed within 250 miles (400 kilometers), if they were detected at all.

The type of SIM card used by Gross is not available on the open market and is distributed only to governments, according to an official at a satellite telephone company familiar with the technology and a former U.S. intelligence official who has used such a chip. The officials, who spoke on condition of anonymity because of the sensitivity of the technology, said the chips are provided most frequently to the Defense Department and the CIA, but also can be obtained by the State Department, which oversees USAID.

Asked how Gross obtained the card, USAID spokesman Drew Bailey said only that the agency played no role in helping Gross acquire equipment. “We are a development agency, not an intelligence agency,” he said.

Cuba’s communist government considers all USAID democracy promotion activities to be illegal and a national security threat. USAID denies that any of its work is covert.

Gross’ American lawyer, Peter J. Kahn, declined comment but has said in the past that Gross’ actions were not aimed at subverting the Cuban government.

Cuban authorities consider Internet access to be a matter of national security and block some sites that are critical of the government, as well as pages with content that they deem as counterrevolutionary. Most Cubans have access only to a severely restricted island-wide Intranet service.

Proponents of providing Internet access say it can undermine authoritarian governments that control the flow of information to their people. Critics say the practice not only endangers contractors like Gross, but all American aid workers, even those not involved in secret activities.

“All too often, the outside perception is that these USAID people are intelligence officers,” said Philip Giraldi, an ex-CIA officer. “That makes it bad for USAID, it makes it bad for the CIA and for any other intelligence agency who like to fly underneath the radar.”

Even before he delivered the special SIM card, Gross noted in a trip report that use of Internet satellite phones would be “problematic if exposed.” He was aware that authorities were using sophisticated detection equipment and said he saw workers for the government-owned telecommunications service provider conduct a radio frequency “sniff” the day before he was to set up a community’s Wi-Fi operation.

U.S. diplomats say they believe Gross was arrested to pressure the Obama administration to roll back its democracy-promotion programs. The Cuban government has alleged without citing any evidence that the programs, funded under a 1996 law calling for regime change in Cuba, are run by the CIA as part of an intelligence plan to topple the government in Havana.

While the U.S. government broadly outlines the goals of its aid programs in publicly available documents, the work in Cuba could not exist without secrecy because it is illegal there. Citing security concerns, U.S. agencies have refused to provide operational details even to congressional committees overseeing the programs.

“The reason there is less disclosure on these programs in totalitarian countries is because the people are already risking their lives to exercise their fundamental rights,” said Mauricio Claver-Carone, who runs the Washington-based Cuba Democracy Advocates.

USAID rejected the notion that its contractors perform covert work.

“Nothing about USAID’s Cuba programs is covert or classified in any way,” says Mark Lopes, a deputy assistant administrator. “We simply carry out activities in a discreet manner to ensure the greatest possible safety of all those involved.”

The U.S. National Security Act defines “covert” as government activities aimed at influencing conditions abroad “where it is intended that the role of the United States Government will not be apparent or acknowledged publicly.”

USAID’s democracy promotion work in Cuba was spurred by a large boost in funding under the Bush administration and a new focus on providing communications technology to Cubans. U.S. funding for Cuban aid multiplied from $3.5 million in 2000 to $45 million in 2008. It’s now $20 million.

Gross was paid a half-million dollars as a USAID subcontractor, according to U.S. officials familiar with the contract. They spoke only on condition of anonymity because they are not authorized to discuss the case.

USAID head Raj Shah said democracy promotion is “absolutely central” to his agency’s work. The Obama administration says its Cuba programs aim to help politically repressed citizens enjoy fundamental rights by providing humanitarian support, encouraging democratic development and aiding the free flow of information.

U.S. officials say Gross’ work was not subversion because he was setting up connections for Cuba’s Jewish community, not for dissidents. Jewish leaders have said that they were unaware of Gross’ connections to the U.S. government and that they already were provided limited Internet access. USAID has not said why it thought the community needed such sensitive technology.

Asked if such programs are meant to challenge existing leaders, Lopes said, “For USAID, our democracy programs in Cuba are not about changing a particular regime. That’s for the Cuban people to decide, and we believe they should be afforded that choice.”

“Of course, this is covert work,” said Robert Pastor, President Jimmy Carter’s national security adviser for Latin America and now director of the Center for Democracy and Election Management at American University in Washington. “It’s about regime change.”

Gross, of Potomac, Maryland, was a gregarious man, about 6 feet (1.8 meters) and 250 pounds (113 kilograms). He was hard to miss. He had bought a Rosetta Stone language course to improve his rudimentary Spanish and had scant knowledge of Cuba. But he knew technology. His company specialized in installing communications gear in remote parts of the world.

Gross’ first trip for DAI, which ended in early April 2009, focused on getting equipment in and setting up the first of three facilities with Wi-Fi hotspots that would give unrestricted Internet access to hundreds of Cubans, especially the island’s small Jewish community of 1,500.

To get the materials in, Gross relied on American Jewish humanitarian groups doing missions on the island. He traveled with the groups, relying on individuals to help bring in the equipment, according to the trip reports.

Three people briefed on Gross’ work say he told contacts in Cuba he represented a Jewish organization, not the U.S. government. USAID says it now expects people carrying out its programs to disclose their U.S. government funding to the people they are helping — if asked.

One of Gross’ reports suggests he represented himself as a member of one of the groups and that he traveled with them so he could intercede with Cuban authorities if questions arose.

The helpers were supposed to pack single pieces of equipment in their carry-on luggage. That way, Gross wrote, any questions could best be handled during the X-ray process at security, rather than at a customs check. The material was delivered to Gross later at a Havana hotel, according to the trip reports.

USAID has long relied on visitors willing to carry in prohibited material, such as books and shortwave radios, U.S. officials briefed on the programs say. And USAID officials have acknowledged in congressional briefings that they have used contractors to bring in software to send encrypted messages over the Internet, according to participants in the briefings.

An alarm sounded on one of Gross’ trips when one of his associates tried to leave the airport terminal; the courier had placed his cargo — a device that can extend the range of a wireless network — into his checked bag.

Gross intervened, saying the device was for personal use and was not a computer hard drive or a radio.

According to the trip reports, customs officials wanted to charge a 100 percent tax on the value of the item, but Gross bargained them down and was allowed to leave with it.

“On that day, it was better to be lucky than smart,” Gross wrote.

Much of the equipment Gross helped bring in is legal in Cuba, but the volume of the goods could have given Cuban authorities a good idea of what he was up to.

“Total equipment” listed on his fourth trip included 12 iPods, 11 BlackBerry Curve smartphones, three MacBooks, six 500-gigabyte external drives, three Internet satellite phones known as BGANs, three routers, three controllers, 18 wireless access points, 13 memory sticks, three phones to make calls over the Internet, and networking switches. Some pieces, such as the networking and satellite equipment, are explicitly forbidden in Cuba.

Gross wrote that he smuggled the BGANs in a backpack. He had hoped to fool authorities by taping over the identifying words on the equipment: “Hughes,” the manufacturer, and “Inmarsat,” the company providing the satellite Internet service.

The BGANs were crucial because they provide not only satellite telephone capacity but an Internet signal that can establish a Wi-Fi hotspot for multiple users. The appeal of using satellite Internet connections is that data goes straight up, never passing through government-controlled servers.

There was always the chance of being discovered.

Last year, the Senate Foreign Relations Committee asked about clandestine methods used to hide the programs and reports that some of them had been penetrated.

“Possible counterintelligence penetration is a known risk in Cuba,” the State Department said in a written response to AP. “Those who carry out our assistance are aware of such risks.”

Gross’ first trip to Cuba ended in early April 2009 with establishment of a communications site in Havana.

He went back later that month and stayed about 10 days while a site was set up in Santiago, Cuba’s second-largest city.

On his third trip, for two weeks in June 2009, Gross traveled to a city in the middle of the island identified by a U.S. official as Camaguey. He rented a car in Havana and drove seven hours rather than risk another encounter with airport authorities.

Gross wrote that BGANs should not be used outside Havana, where there were enough radio frequency devices to hide the emissions.

The report for Gross’s fourth trip, which ended early that August, was marked final and summarized his successes: wireless networks established in three communities; about 325 users; “communications to and from the U.S. have improved and used on a regular basis.” He again concluded the operation was “very risky business.”

Gross would have been fine if he had stopped there.

In late November 2009, however, he went back to Cuba for a fifth time. This time he didn’t return. He was arrested 11 days later.

An additional report was written afterward on the letterhead of Gross’ company. It was prepared with assistance from DAI to fulfill a contract requirement for a summary of his work, and so everyone could get paid, according to officials familiar with the document.

The report said Gross had planned to improve security of the Havana site by installing an “alternative sim card” on the satellite equipment.

The card would mask the signal of the BGAN as it transmitted to a satellite, making it difficult to track where the device was located.

The document concluded that the site’s security had been increased.

It is unclear how DAI confirmed Gross’ work for the report on the final trip, though a document, also on Gross’ company letterhead, states that a representative for Gross contacted the Jewish community in Cuba five times after his arrest.

In a statement at his trial, Gross professed his innocence and apologized.

“I have never, would never and will never purposefully or knowingly do anything personally or professionally to subvert a government,” he said. “I am deeply sorry for being a trusting fool. I was duped. I was used.”

In an interview with AP, his wife, Judy, blamed DAI, the company that sent him to Cuba, for misleading him on the risks. DAI spokesman O’Connor said in a statement that Gross “designed, proposed, and implemented this work” for the company.

Meanwhile, the 62-year-old Gross sits in a military prison hospital. His family says he has lost about 100 pounds (45 kilograms) and they express concern about his health. All the U.S. diplomatic attempts to win his freedom have come up empty and there is no sign that Cuba is prepared to act on appeals for a humanitarian release.

Current in Westfield – Ham radio enthusiasts invited to join club

1329901109 67 Current in Westfield – Ham radio enthusiasts invited to join club

A local amateur radio club is inviting all Federal Communications licensed amateur radio operators, as well as those who would like to obtain a license, to join and enjoy the camaraderie of fellow operators and great programs about amateur radio (also known as ham radio) technologies, and the latest news about activities in the area. The Hamilton County Amateur Radio Emergency Services Club has programs each month to provide information and discussion about all areas of the rapidly-growing hobby.

HCARES meets the first Saturday of every month and features programs about various topics of ham radio interest in the area. While the thrust of the club is public service, its activities include virtually every facet of amateur radio, including occasional field trips.

There are more than 700 licensed radio amateurs in Hamilton County and the number increases daily. Today’s ham radio encompasses the latest microprocessor technologies in digital radio and satellite operations. Local hams are able to communicate “when all else fails,” enabling them to set up emergency communications when severe storms or other disasters knock out cell towers, commercial power and landline communications everyone depends on every day.

The Feb. 4 meeting at Noblesville Fire Station No. 6, 16800 Hazel Dell Rd, will include a presentation by Eric Eilers, K9ZX, about how to use a  random length of wire to serve as a great antenna for amateur radio communications.

The meeting will start at 10:00 a.m. and everyone is welcome. Whether or not you are licensed, the HCARES club offers a wide range of activities and programs, which include help in obtaining a license and actual exams by certified American Radio Relay League volunteer examiners.

“Ham radio is a hobby that includes virtually all ages, occupations and interests,” said Steve Quear, president of the club. “Our members include physicians, police and firefighters, housewives, CEOs, mechanics and virtually all occupations, including young students to retired engineers. You don’t have to be a scientist to enjoy ham radio, just an interest in electronics, public service and talking with folks around the world.”

For more information, contact Joe March, KJ9M, at 317-748-1926.

Your not totally out of luck if you get a radio that needs work.? They have a high energy level. This month is going to be a little bit different from the previous one. The radio equipment required is not overly expensive in my opinion. More than a few years ago, okay about 25 or so, all the rage was the IC-2AT. To get the rough equivalent of meters from MHz just divide MHz by 300. It left an importanta impression. A lot of what you've heard might sound overwhelming. Ham radio licenses can be renewed anytime from 90 days before they expire to a full two-years after they expire (it is important to note that it is illegal to operate a ham radio with an expired amateur radio license...you must wait for it to be renewed before you can legally operate a radio using the ham radio frequencies). Of course, the True Believers would have you believe that KenIcoYaeTen rigs are the best, but and here's the secret right out there the only way you're going to find out what's best for you is by using it yourself. It need not be. The bands are not crowded because signals don't travel as far as they do during the high parts of the cycle and because not as many people are involved in the hobby right now. Here are a couple of reviews by mobs. Not everyone feels comfortable with used ham radio although the next time I hear that question with respect to ham radio test questions I'll scream. 9)Erect center support bracketing to roof line. Also, you may need a copy to show to police officers, etc.

Beardstown Police squelch digital radio rumors

1329896318 74 Beardstown Police squelch digital radio rumors

In the past week, speculation that the Beardstown Police Department has switched to a digital radio system has generated dozens of calls to the department from concerned individuals.

A lot of people expressed concern the city would be following in the Cass County Sheriff’s Department’s footsteps and moving toward the high-tech communication devices that most scanners can’t pick up.

In fact, Sheriff Bob Fair said the county’s radio system is encrypted, meaning that even the newer, more expensive digital scanners can’t broadcast the talk.

While Fair said his department was lucky to have received a grant for the new system that went into place over the last few months, similar systems are too costly for most departments to buy on their own.

Beardstown Police Chief Tim Schlueter said when the county went digital, the city was able to get a few units to try out, but the city still has its own standard frequency and no immediate plan to make the upgrade. But it is something he is considering.

“With dispatch being out of Virginia, it might become an issue trying to reach each other when you’re inside buildings,” he said.

Fair said since the county received a $500,000 grant to upgrade its 911 system and upgrade its radios, the increase in quality has been tremendous.

“Before, the radio system we had, in some of the towns in our county we had no dispatching or any radio service at all, sometimes even with mobile phones. They’d be totally on their own,” Fair said. “As a safety concern, of my deputies, and even myself, this was the best. … It’s been totally the opposite of what we’re used to.”

Many scanner enthusiasts have raised concerns encrypted digital radios allow law enforcement to operate with far less public scrutiny.

“I don’t see it as a concern, because the bad guys can’t hear us either,” Fair said. “The burglars and people out there committing crimes can’t hear what we’re doing, as well.”

While the Illinois State Police has been operating a digital system for several years, it still an expensive technology for most law enforcement agencies.

Morgan County Sheriff’s Department Chief Deputy Mike Carmody said at the present time, his department has no plans to upgrade its system

“We have an established radio system in place,” he said. “I’m sure as the costs go down that will be something we’ll look into. But right now we don’t have the financial means to do anything like that.”

Focused Radiation May Ease Facial Pain

1329892707 31 Focused Radiation May Ease Facial Pain30932

Cyberknife radiosurgery may bring at least short-term relief to patients with refractory trigeminal neuralgia, according to results of a small series of cases.

Overall, 88% (14 of 16) of the patients with surgically refractory unilateral trigeminal neuralgia (TN) who underwent the radiosurgical procedure responded favorably, with partial or complete relief from their symptoms, reported Orlando Ortiz, MD, and colleagues from the Winthrop University Hospital in Mineola, N.Y., in the Journal of NeuroInterventional Surgery.

In addition, 11 of the 14 patients who responded to treatment were completely free of pain at some point in their post-treatment course and seven of those remained pain-free at their last visit (average of five months).

TN is an idiopathic disorder characterized by paroxysmal attacks of sharp, cutting, or electric shock-like pain that occur within the trigeminal nerve distribution, the authors explained.

Since the mid-1990s, TN treatment has included stereotactic isocentric gamma knife and linear accelerator radiosurgery to perform a rhizotomy, targeting various portions of the proximal trigeminal nerve. However, that modality has multiple side effects, including numbness, anesthesia dolorosa, and diplopia.

“The Cyberknife system, on the other hand, delivers a non-isocentric beam of radiation better suited for targeting the trigeminal nerve with greater target fidelity and enhanced patient comfort,” the authors stated.

In this case series, 17 consecutive patients with TN underwent Cyberknife surgery from May 2007 to July 2009. All were evaluated for pain, had a neurological examination, and underwent imaging with a neurosurgeon, an interventional neuroradiologist, and a radiation oncologist prior to the procedure.

All patients underwent CT cisternography for treatment planning. The target area, a 6-mm segment of the nerve roughly 2 mm to 3 mm distal to the dorsal root, was identified by superimposing the cisternogram with MR images.

The Cyberknife from Accuray of Sunnyvale, Calif., was used to perform radiosurgical rhizotomy using a single collimator to deliver an average maximum dose of 73.06 Gy. Accuray did not propose or fund the case review, Ortiz and colleagues indicated.

Initial follow-up visits were done at three weeks post-procedure radiation with additional visits on an outpatient basis. The 16 patients had post-treatment interactions for an average of 11.8 months.

Four patients experienced a relapse in their symptoms at three, 7.75, nine, and 18 months after therapy, respectively. Three of the four underwent balloon compressions, while the fourth had only mild and occasional symptoms that were controlled with medical management.

One of the two patients who did not respond this therapy had also failed two previous decompressions and gamma knife surgery. The other patient with refractory disease underwent unsuccessful treatments ranging from ethanol/radiofrequency ablation to orbital neurectomy.

Only two patients reported side effects related to the radiosurgery. One of the patients, who remained pain-free, developed a bothersome feathery dysesthesia in the maxillary and mandibular V2+V3 divisions of the trigeminal nerve after 13 months. The second patient reported a non-bothersome mild jaw hypoesthesia at two months. There were no substantial complications such as anesthesia dolorosa, the authors reported.

A limitation of this study was that it was short-term and retrospective in a small group of patients. The authors also did not use a formalized scale, such as the Barrow Neurological Institute Facial Numbness scale, for an objective measure of hypoesthesia. The relatively short follow up for some of these patients may have lead to an incomplete assessment of recurrence.

The authors pointed out that the minimally invasive nature of radiosurgery makes it an attractive alternative with improving efficacy, particularly as the first lesioning procedure in patients without vascular compression.

“Further investigation and future comparative studies between Cyberknife, gamma knife, and surgical treatment potentially will show Cyberknife’s viable role in treating TN,” they said.

The authors reported no competing interests.
