ARMAS, Associated Press Writer WASHINGTON - A Senate Democrat influential on telecommunications issues has asked federal regulators to investigate whether any laws were broken by broadcasters who aired video news releases produced by the government. Stations may have violated the law if they used the video releases without disclosing that the government was the source of the information, Sen. Daniel Inouye, D-Hawaii, wrote in a letter to the Federal Communications Commission. The FCC should "take any remedial measures necessary to prevent station owners from misleading their viewers", said Inouye, adding that any lack of disclosure also represents "a serious breach of journalistic ethics." Inouye, ranking Democrat on the Senate Commerce, Science and Transportation Committee, said the FCC should also scrutinize whether stations violated prohibitions against accepting "money, service or other valuable consideration for the airing of content." The commission will "take the letter very seriously and will look into it," FCC spokesman David Fiske said Thursday. Generally, the FCC reviews letters and complaints before determining if there should be an investigation. The Republican White House has for some time been preparing and distributing 'press releases' without any attribution to the source, and many people who have read these 'press releases' have said they amounted only to government propoganda. The White House has defended the video releases, which are distributed to television stations across the country. The videos are frequently used without any disclosure of the government's role in their production by claiming they are 'truthful accounts'. President Bush at a news conference Wednesday pointed to a Justice Department memo issued last week that concluded the practice was appropriate so long as the videos presented factual information about government activities. "Now I also think it would be helpful if local stations then disclosed to their viewers that this was based upon a factual report and they chose to use it," Bush said. "But evidently in some cases that's not the case." The Justice guidelines conflicted with an opinion from the Government Accountability Office, the investigative arm of Congress. The videos could amount to illegal "covert propaganda" if stations did not clearly state the source of the information, the GAO said. There has been increased scrutiny on government media practices since the revelation in January that conservative columnists were paid to plug the administration's agenda and did not tell their audiences that they had received money. Bush, after the practice was disclosed, said it was wrong and ordered that it stop, then in February, a gay male prostitute who operated gay pornographic websites was found to be operating daily from the Press Room at the White House doing 'cut and paste' Republican press releases for 'Talon', an alleged web site with political news. The FCC is investigating at least one of those cases, involving commentator Armstrong Williams and his deal with the Education Department to promote the No Child Left Behind Act.

Now the Internet is shaking up this once-staid and lucrative business. Newspaper publishers that once enjoyed a virtual monopoly on the classified market are facing increasing competition, including from Web sites like eBay Inc. Experts wonder if free online ads and innovations that allow sellers of everything from exotic cars to Pez candy dispensers to reach a massive audience via the Web will expand the business for all or inflict serious damage on incumbents. EBay, best known for its auction site, has spent more than $850 million to buy three online classified companies in the United States and abroad. Last summer, the Web marketplace took a 25 percent stake in mostly free, San Francisco-based Craigslist.org (http://www.craigslist.org), an online classified shop that covers about 100 cities worldwide. EBay recently launched free classified Web sites in seven international markets including Germany, China and Japan. Those new Kijiji-branded sites (http://kijiji.com) mimic Craigslist. Moves like these are causing havoc with newspapers, many of which have fought back with online versions of their publications -- complete with classifieds. "It's a free-for-all," said Peter Zollman, founding principal of consulting firm Classified Intelligence. "I think the threat (to newspapers) is very real because classified advertising is so lucrative." The Newspaper Association of America expects the market for print newspaper classified advertising to grow 5.2 percent to $17.4 billion this year. But newspaper market share is falling amid intense competition from a range of players, including Web sites and Internet search companies, as well as radio and television, niche publications and Yellow Pages providers, Zollman said. Newspapers remain the dominant medium for listing jobs and selling cars and homes in most local markets, but Zollman warned they must work to keep that hold. "I don't think they'll go out of business, but the business is being transformed very fast," he said. Analysts who focus on the Web also point to the success of companies like Yahoo Inc. and MSN Web unit, which have seen their banner and branded ad revenue grow as big advertisers follow audiences from television to the Internet. ROOM FOR ALL? Still, some analysts see the changing classified ad market resulting in a larger sea that can float all boats. "It's a case of one and one equaling 2 1/2," said Ed Atorino, a publishing analyst at Fulcrum Global Partners. "It doesn't seem to be taking away a lot of dollars from the traditional media; it just seems to be a new market." Print newspaper classified revenue declined from 2001 to 2003, when the broader ad market was soft, but has risen in every other year since the Web went mainstream in 1995. The Kelsey Group estimates that total revenue from U.S. Web classifieds was $1.95 billion in 2004, excluding eBay, but including sites operated by newspapers. Auto sales typically constitute the biggest chunk of classified ad spending at newspapers, followed by help-wanted and real-estate listings, while Web classifieds are dominated by jobs, followed by dating and autos. The help-wanted market may be a harbinger for the future push and pull between the online and offline worlds. Newspaper job listings were the first to feel the heat from Internet rivals like Monster.com. Most newspaper chains during 2004 continued to lose online recruitment market share to rivals, based on the number of job postings, according to Corzen, a New York market research firm. Help-wanted revenue growth at newspapers also lags that of online job posting sites. But there were some bright spots. Online recruiting site Careerbuilder jointly owned by newspaper publishers Gannett Co. Inc., Knight Ridder Inc. and Tribune Co. gained market share, as did Hollinger International and Pulitzer Inc. Newspapers are also fighting back on other fronts. For example, Hearst Corp.'s San Francisco Chronicle is giving extended listings to unsuccessful sellers, while Miami Herald and San Jose Mercury News publisher Knight Ridder lets people buy online-only ads, with or without pictures. Still others allow their news items to be used freely in exchange for advertising revenue earned through online sources. Reuters Limited is one such example. Kelsey analyst Greg Sterling said the jury is still out, but newspapers appear to be worse off than before the arrival of online rivals. "It's very hard to know what kind of dollars have been lost from newspapers," he said. "I think it's substantial."

Now they're also attracting identity thieves looking to turn stolen credit cards into cash. Some Internet phone services allow scam artists to make it appear that they are calling from another phone number -- a useful trick that enables them to drain credit accounts and pose as banks or other trusted authorities, online fraud experts say. "It's like you've handed people an entire phone network," said Lance James, who as chief technology officer of Secure Science Corp. sees such scams on a daily basis. The emerging scams underline the lower level of security protecting Voice Over Internet Protocol, or VOIP, the Internet-calling standard that has upended the telecommunications industry over the past several years. Traditional phone networks operate over dedicated equipment that is difficult for outsiders to penetrate. Because VOIP calls travel over the Internet, they cost much less but are vulnerable to the same security problems that plague e-mail and the Web. Internet worms that snarl online networks can render VOIP lines unusable, and experts at AT&T say VOIP conversations can be monitored or altered by outsiders. Federal Trade Commission Chairman Deborah Platt Majoras recently warned that unscrupulous telemarketers could use VOIP to blast huge numbers of voice messages to consumers, a technique known as SPIT, for "spam over Internet telephony." All of these threats remain largely in the realm of theory. Caller ID spoofing, on the other hand, has emerged over the past six months as a useful tool for identity thieves and other scam artists, according to fraud experts. PRESIDENT BUSH ON THE LINE Any reporter would scramble for a ringing phone that reads "White House media line" on its caller ID display. But it's not the Bush administration on the line -- it's security instructor Ralph Echemendia, calling from a mobile phone on a remote Georgia highway. "You can see how this sort of thing could be used in a very malicious way," said Echemendia, a security instructor at the Intense School, a technology training company. Caller ID spoofing is not prohibited by law, but the Federal Communications Commission requires telemarketers to identify themselves accurately, a spokeswoman said. Echemendia built his own system to spoof calls, but several free or low-cost services allow even technical novices to falsify caller ID information as well. Debt collectors and private investigators use Camophone.com's 5-cents-per-call service to trick people into answering the phone, according to messages posted on a discussion board. Traveling salesmen say the service comes in handy when they want clients to return calls to the main office, rather than their motel room. James said criminal uses of caller-ID spoofing have become common over the last six months. Wire-transfer services like Western Union require customers to call from their home phone when they want to transfer money in an effort to deter fraud -- a barrier easily sidestepped by any identity thief using a caller-ID spoofing service. Fraud rings can now transfer money directly out of stolen credit-card accounts, rather than buying merchandise and reselling it, he said. Western Union spokeswoman Danielle Periera said the company has no other way to verify that transfer requests are valid. "We try hard to stay one step ahead of them and recognize that scam artists are sophisticated and often change their schemes," she said. Criminals can use caller-ID spoofing to listen to other people's voice mail, James said, especially when those accounts are not protected by passwords. They also have begun to use the technology to make it appear that they are calling from a bank or other financial institution, said Dave Jevans, who chairs the Anti-Phishing Working Group, a banking-industry task force. That helps them convince consumers to divulge account numbers, passwords and other sensitive information in a scam that echoes the "phishing" e-mails that have become common, he said. VOIP industry pioneer Jeff Pulver, whose Free World Dialup service can be used to spoof calls, said he couldn't prevent abuse of his system. The problem will likely recede as companies like VeriSign Inc. and NeuStar Inc. develop ways to verify online identities, he said: "We're not there yet, but we're going to get there."

In fact, says Mark Dineen, the general manager and a corporate vice president of WOW Internet Cable and Phone, the biggest complaint he gets is from people outside the service areas of 42 Detroit-area communities who want WOW but can't get it. Dineen's company was just rated No. 1 by cable TV subscribers in a nationwide J.D. Power and Associates survey that measured customer satisfaction. Comcast, the area's dominant cable provider, ranked seventh. [.....] WOW was founded in Colorado in 1999 and then moved to the Midwest in 2001 when it acquired the cable assets of Ameritech New Media. The Colorado operation broke off from the main corporation and is operated separately. [.....] Two weeks ago, WOW rolled out one of the industry's most aggressive bundled packages that includes digital telephone service. For $89.99 a month, customers get cable television, basic Internet and unlimited local and long distance telephone calls. The system, which allows customers to keep their existing phone numbers, uses Voice over Internet Protocol (VoIP) to patch two-way phone calls through the WOW network to the Sprint land-based network. "This really is the future," says Dineen, 40, a resident of Troy. "People get digital quality and all the caller ID and call forwarding and 911 features they expect, but never have to pay long distance fees."

It's from the NY Times. Note the risk to the innocent individual user, which is explained in the last paragraph. * Original: From..... Bill Craig March 19, 2005 Growth of Wireless Internet Opens New Path for Thieves By SETH SCHIESEL <http://query.nytimes.com/search/query?ppds=bylL&v1=SETH SCHIESEL&fdq=19960101&td=sysdate&sort=newest&ac=SETH SCHIESEL&inline=nyt-per> The spread of the wireless data technology known as Wi-Fi has reshaped the way millions of Americans go online, letting them tap into high-speed Internet connections effortlessly at home and in many public places. But every convenience has its cost. Federal and state law enforcement officials say sophisticated criminals have begun to use the unsecured Wi-Fi networks of unsuspecting consumers and businesses to help cover their tracks in cyberspace. In the wired world, it was often difficult for lawbreakers to make themselves untraceable on the Internet. In the wireless world, with scores of open Wi-Fi networks in some neighborhoods, it could hardly be easier. Law enforcement officials warn that such connections are being commandeered for child pornography, fraud, death threats and identity and credit card theft. "We have known for a long time that the criminal use of the Internet was progressing at a greater rate than law enforcement had the knowledge or ability to catch up," said Jan H. Gilhooly, who retired last month as special agent in charge of the Secret Service field office in Newark and now helps coordinate New Jersey operations for the Department of Homeland Security. "Now it's the same with the wireless technologies." In 2003, the Secret Service office in Newark began an investigation that infiltrated the Web sites and computer networks of suspected professional data thieves. Since October, more than 30 people around the world have been arrested in connection with the operation and accused of trafficking in hundreds of thousands of stolen credit card numbers online. Of those suspects, half regularly used the open Wi-Fi connections of unsuspecting neighbors. Four suspects, in Canada, California and Florida, were logged in to neighbors' Wi-Fi networks at the moment law enforcement agents, having tracked them by other means, entered their homes and arrested them, Secret Service agents involved in the case said. More than 10 million homes in the United States now have a Wi-Fi base station providing a wireless Internet connection, according to ABI, a technology research firm in Oyster Bay, N.Y. There were essentially none as recently as 2000, the firm said. Those base stations, or routers, allow several computers to share a high-speed Internet connection and let users maintain that connection as they move about with laptops or other mobile devices. The routers are also used to connect computers with printers and other devices. Experts say most of those households never turn on any of the features, available in almost all Wi-Fi routers, that change the system's default settings, conceal the connection from others and encrypt the data sent over it. Failure to secure the network in those ways can allow anyone with a Wi-Fi-enabled computer within about 200 feet to tap into the base station's Internet connection, typically a digital subscriber line or a cable modem. Wi-Fi connections are also popping up in retail locations across the country. But while national chains like Starbucks take steps to protect their networks, independent coffee shops that offer Wi-Fi often leave their connections wide open, law enforcement officials say. In addition, many universities are now blanketing campuses with open Wi-Fi networks, and dozens of cities and towns are creating wireless grids. While some locations charge a fee or otherwise force users to register, others leave the network open. All that is needed to tap in is a Wi-Fi card, typically costing $30 or less, for the user's PC or laptop. (Wi-Fi cards contain an identification code that is potentially traceable, but that information is not retained by most consumer routers, and the cards can in any case be readily removed and thrown away.) When criminals operate online through a Wi-Fi network, law enforcement agents can track their activity to the numeric Internet Protocol address corresponding to that connection. But from there the trail may go cold, in the case of a public network, or lead to an innocent owner of a wireless home network. "We had this whole network set up to identify these guys, but the one thing we had to take into consideration was Wi-Fi," Mr. Gilhooly said. "If I get to an Internet address and I send a subpoena to the Internet provider and it gets me a name and physical address, how do I know that that person isn't actually bouncing in from next door?" Mr. Gilhooly said the possibility of crashing into an innocent person's home forced his team to spend additional time conducting in-person surveillance before making arrests. He said the suspects tracked in his investigation would regularly advise one another on the best ways to gain access to unsecured Wi-Fi systems. "We intercepted their private conversations, and they would talk and brag about, 'Oh yeah, I just got a new amplifier and a new antenna and I can reach a quarter of a mile,' " he said. "Hotels are wide open. Universities, wide open." Sometimes, suspected criminals using Wi-Fi do not get out of their car. At 5 a.m. one day in November 2003, the Toronto police spotted a wrong-way driver "with a laptop on the passenger seat showing a child pornography movie that he had downloaded using the wireless connection in a nearby house," said Detective Sgt. Paul Gillespie, an officer in the police sex crimes unit. The suspect was charged with child pornography violations in addition to theft of telecommunications services; the case is pending. "The No. 1 challenge is that people are committing all sorts of criminal activity over the Internet using wireless, and it could trace back to somebody else," Sergeant Gillespie said. Holly L. Hubert, the supervisory special agent in charge of the Cyber Task Force at the F.B.I. field office in Buffalo, said the use of Wi-Fi was making it much more difficult to track down online criminals. "This happens all the time, and it's definitely a challenge for us," she said. "We'll track something to a particular Internet Protocol address and it could be an unsuspecting business or home network that's been invaded. Oftentimes these are a dead end for us." Ms. Hubert says one group of hackers she has been tracking has regularly frequented a local chain of Wi-Fi-equipped tea and coffee shops to help cover its tracks. Many times the suspects can find a choice of unsecured wireless networks right from home. Special Agent Bob Breeden, supervisor of the computer crime division for the Florida Department of Law Enforcement, said a fraud investigation led in December to the arrest of a Tallahassee man who had used two Wi-Fi networks set up by residents in his apartment complex. Over those Internet connections, the suspect used the electronic routing information for a local college's bank account to pay for online pornography and to order sex-related products, Mr. Breeden said. The man was caught because he had the products delivered to his actual address, Mr. Breeden said. When officers went to arrest him, they found his computer set up to connect to a neighbor's wireless network. Mr. Breeden said the suspect, Abdul G. Wattley, pleaded guilty to charges of theft and unauthorized use of a communications network and was sentenced to two years' probation. In another recent case, the principal of a Tallahassee high school had received death threats by e-mail, Mr. Breeden said. When authorities traced the messages to a certain Internet Protocol address and went to the household it corresponded to, Mr. Breeden said, "Dad has his laptop sitting on a table and Mom has another laptop, and of course they have Wi-Fi, and they clearly didn't know anything about the threats." Cybercrime has been known to flourish even without Wi-Fi's cloak of anonymity; no such link has been found, for example, in recent data thefts from ChoicePoint, Lexis/Nexis and other database companies. But unsecured wireless networks are nonetheless being looked at by the authorities as a potential tool for furtive activities of many sorts, including terrorism. Two federal law enforcement officials said on condition of anonymity that while they were not aware of specific cases, they believed that sophisticated terrorists might also be starting to exploit unsecured Wi-Fi connections. In the end, prevention is largely in the hands of the buyers and sellers of Wi-Fi equipment. Michael Coe, a spokesman for SBC, the nation's No. 1 provider of digital subscriber line connections, said the company had provided about one million Wi-Fi routers to its customers with encryption turned on by default. But experts say most consumers who spend the $60 to $80 for a Wi-Fi router are just happy to make it work at all, and never turn on encryption. "To some degree, most consumers are intimidated by the technology," said Roberta Wiggins, a wireless analyst at the Yankee Group, a technology research firm in Boston. "There is a behavior that they don't want to further complicate their options." That attitude makes life easier for tech-savvy criminals and tougher for those who pursue them. "The public needs to realize that all they're doing is making it harder on me to go find the bad guys," said Mr. Gilhooly, the former Secret Service agent. "How would you feel if you're sitting at home and meanwhile someone is using your Wi-Fi to hack a bank or hack a company and downloads a million credit card numbers, which happens all the time? I come to you and knock on your door, and all you can say is, 'Oops.'

As Sullivan acknowledged, some old TV sets did work like Bonomi's 1930s Crosley: they required "tuning in on a single band by twiddling an analog variable tuning capacitor to the right frequency [which] would have been difficult." But by the 1950s, TV set manufacturers were installing "turret tuners" to simplify VHF tuning. A single knob rotated a cylindrical mechanism fitted with twelve little hand-wired circuit boards, one for each channel. Each circuit board had a bunch of capacitors, some hand-wound coils, and a row of metal contacts that mated with metal springs. As each circuit board was brought into position by the rotating mechanism, the springs mated with the contacts on the board, placing that board in the circuit. After the introduction of UHF, turret tuners were manufactured with 13 circuit boards, one for each VHF channel + one that switched to a separate UHF tuner. The UHF tuner was tuned in one continuous-tuning dial. Sullivan continued: > Later on, [turret] tuners had separate fine- tuners for each channel > so one wouldn't need to retune when switching from station to > station. On each channel, the fine-tuning control engaged a tuning slug inside one of the little hand-wound coils. Here's a link to a picture showing a turret VHF tuner (left) and what appears to be a continuous-tuning UHF tuner (right). This particular photo happens to be on a British website, but the basic structure of the turret mechanism is the same in the USA. http://www.thevalvepage.com/valvetek/guidgrid/GGRID2.JPG Back in my cable TV days during the 70s, turret tuners used to drive us nuts. There was only one VHF TV station in the market (Channel 3), so if a viewer wasn't hooked to cable, the only exercise the tuner got was from getting flipped back and forth between UHF and 3. This kept the contacts on UHF, 2, and 3 clean, but the rest of the contacts got pretty dusty and/or corroded. If this viewer then connected to cable (just 12 channels in those days), suddenly, all 12 VHF circuit boards were needed. We spent a lot of time explaining, "I'm sorry, sir, your TV set's tuner needs to be cleaned ... please take it to the TV repair shop of your choice ... no we do not repair television sets ... our franchise agreement specifically prohibits it." Things got even worse when we introduced our first pay service (HBO) in 1978. We "hid" it in the midband on cable channel 17, "in the clear" (not scrambled, not trapped). We provided each HBO sub with a primitive converter: a little box with a single two-position switch: - One position converted channel 17 to channel 2 for HBO. - One position passed the incoming cable signal through unaltered for channels 2-13. It wasn't very good security, but the powers-that-were considered it to be good enough, since turret tuners couldn't tune it. Well, it wasn't long before local TV shops discovered a new line of business: retuning one of the lesser-used turret circuit boards (like public access) to channel 17. Of course, Bonomi's old Crosley would have tuned to it. But by the 1970s, virtually all TV sets used turret VHF tuners. Varactor tuners with digital displays were just coming on the market, and the old continuous-tuning models had just about disappeared. A few years later, we moved HBO to channel 2 (so we could sell HBO to hotels and motels), installed negative traps to secure it, and abandoned all those old two-position-switch converters. But some people never figured it out: for years thereafter, those old boxes kept appearing at garage sales and flea markets, sometimes accompanied by "get HBO free" signs. As for the folks who paid some TV shop to illicitly retune a circuit board to channel 17 ... well, they got what they paid for.

I believe 200 is 108.0, > 201 is 88.0, and I'm not sure how they numbered the space below 88.0. Channel 200 is 87.9; 201 is 88.1, and so on up to 300 which is 107.9. There are two stations in the entire U.S. on channel 200: KSFH, a high-school station in Mountain View, Calif., and K200AA, a Calvary satellator in Sun Valley, Nev. In addition, Federal Signal Corp. has an experimental license for WA2XNX in Brazos, Tex., but I have no idea if this station is operating. Channel 200 is reserved for non-commercial, class-D stations which have been "bumped" by a primary station from their previous channel, and for which no other FM channel would be technically permissible. I suspect this rule was made specifically for KSFH, which was for many years the only station on the channel; K200AA was just recently built. -GAWollman -- Garrett A.

The allocations here were also all shifted upward by 1kHz following a WARC conference in 1978, so 899, 908, 917kHz became 900, 909, 918 etc. > There is something similar in FM.

Yes, FM broadcasts in Europe use both even and odd slots, and in Britain there have even been some stations given a 50kHz allocation, i.e. xx.x5 MHz. > One other peculiarity: in most countries, FM is about 88 to 108 > MHz.

The former Soviet Bloc countries in eastern Europe also had their own FM band. I can't remember the details, but I think it was somewhere around the 60 to 70MHz region. In Britain, the original FM broadcast band ran only from 88 to 100MHz. The band above 100MHz was used for two-way radio, a fact soon discovered by even the casual listener when imported radios covering right up to 108MHz started to appear in the country. The broadcast band was extended right up to 108MHz after the other services had been moved to different frequencies in the 1980s. Another minor technical variation here is that we use a different pre-emphasis curve on FM broadcasts: 50uS vs. 75uS. - Paul. ------------------------------ TELECOM Digest is an electronic journal devoted mostly but not exclusively to telecommunications topics.
