August Auto Sales Could Be the Worst in Nearly Three Decades
Posted by: Richard T. Mindler , Jr. 9-1-10
Auto sales started out August on an upbeat note, with early trends showing the month could go down as the best so far this year. But as August winds down, it appears consumers were less eager to buy than first thought, despite the bevy of end-of-model-year deals.
In fact, August could go down as the slowest sales month in 28 years, Bloomberg News reported. Industry-wide, automakers are expected to report Wednesday that monthly sales totaled an annualized rate of 11.6 million vehicles, according to a composite estimate of eight analysts.
The last time auto sales were that low was August 1982, when the nation was mired in recession, according to researcher Ward’s AutoInfoBank. The rate is also 18% lower than the 14.2 million pace recorded during last year’s “cash for clunkers” rebate program, which boosted purchases and made August one of the best sales months in 2009.
Market Distortion From Cash for Clunkers
People aren’t buying because of the economy. With recovery seemingly stalled, Americans aren’t eager to take on more debt when their jobs may be at risk. Reduced home values and lower stock prices are also hampering auto sales, since households feel less wealthy.
Edmunds.com reports similar sales expectations for the month. The online car-buying guide predicts sales in August reached an annualized rate of 11.8 million, up from 11.5 million in July.
Comparisons between the current month and August 2009, are “a waste of time since ‘cash for clunkers’ distorted the market so badly last year,” said Jessica Caldwell, director of industry analysis for Edmunds.com. “It is likely that the current slow sales pace can be partly attributed to the thousands of ‘pull-ahead’ sales that last year’s CARS program stole from subsequent months.”
Despite a 1% boost in incentives for the month compared to July — to an average $2,864 for each vehicle sold — retail sales likely fell 7% in August compared to the previous month, according to industry tracker TrueCar.
Leaders and Laggers
TrueCar forecasts sales at Ford Motor ( F), Toyota Motor (TM), Mercedes-Benz and Honda Motor (HMC) rose during the month compared to July, with Mercedes and Honda each recording a 10% increase, while Ford’s sales climbed 5.6% and those at Toyota grew just 1%. Japanese automaker Mazda Motor may have enjoyed the best increase, with expectations that its U.S. sales jumped 21%, compared to July.
General Motors, Chrysler Group, Subaru and Hyundai Motor are expected to report flat sales, with Nissan Motors ( NSANY), BMW, Kia Motors and Volkswagen each reporting fewer vehicles sold.
Honda sales appear to have benefited from increased discounts and Toyota’s continuing recall woes. Honda boosted incentives by 66% from a year ago, Bloomberg reported, citing TrueCar data, while Nissan and Toyota raised discounts by less than half that amount.
Among domestic automakers, GM and Ford both increased incentives — 18% and 25%, respectively, in August, compared to a year ago. Chrysler, however, bucked the trend, reducing discounts 22%, compared to August 2009.
Summer 2010 Intense Heat — U.S. and Globally !
(Aug. 1) — Summer 2010 is far from over, but extremely hot weather has been a major weather story to date, not only in the United States but also in other parts of the northern hemisphere. All-time record high temperatures have been tied or broken in more than a dozen nations.
Across the United States, the heat has been particularly persistent in the southern and eastern parts of the country. A July heat wave produced 100-plus-degree heat along the Eastern Seaboard from southern New England to the Virginias, including temperatures in excess of 105° F in parts of Maryland (including Baltimore) and Virginia. Hartford, Connecticut, tied its all-time record high temperature of 102° F on July 6.
Globally, at least 14 different countries have reported all-time record high temperatures this year (not all have been during the northern hemisphere summer), according meteorologist to Jeff Masters of Weather Underground.

On Thursday of this last week, all-time record high temperatures were established in Moscow, Russia, with a high of 102° F. The heat has been persistent — this will be the hottest July on record by far — and accompanied by a severe drought, damage to crops and wildfires. In addition, Finland established a new all-time record for heat on Thursday when the temperature hit 99 degrees in Joensuu.
The most intense heat of the summer has occurred in the typically hot Middle East. All-time record high temperatures have been established in Saudi Arabia, Iraq (125.6° F for both) and Pakistan (128.3° F).
The intense heat in both cases — across the United States and in Europe/Middle East — has been produced by persistent and strong high pressure systems in the upper levels of the atmosphere.
Across the United States, it’s common for a high pressure system to be dominant in the summer, but the high has been centered farther to the east than it is during most summers, resulting in the core of the heat being focused farther to the east. While there have been occasional breaks from the intense heat in the Mid-Atlantic and Northeast, the heat has been more persistent in the Deep South. Temperatures average three to five degrees above normal in June and two to four degrees above normal in July.
With the heat focused farther to the east, it’s actually been cooler than normal in Southern California, especially close to the coast where water temperatures have been lower than normal. Temperatures in July have averaged three to five degrees cooler than average from Los Angeles to San Diego. Each city had a record cool day. The Los Angeles International Airport (LAX) had a high of 67° F on July 9, and San Diego recorded a high temperature of 64° F on July 8 .
Across Europe and the Middle East, a high pressure system in the summer is also common; however, its strength typically waxes and wanes. This summer, it’s been more persistently strong than it is during most summers, allowing the heat to occur with more frequency and intensity.

Scholar Claims to Have Unlocked ‘The Plato Code’
LONDON (June 30) — A scholar unlocks a code buried within ancient Greek texts to discover secret messages left by a long-dead philosopher. This isn’t the plot of the next Dan Brown novel, but the result of an English academic’s five-year-long study of Plato.
Jay Kennedy of the University of Manchester claims that Plato (who died around 347 B.C.) wove a complex musical and mathematical cipher into the text of famed dialogues like “The Republic.” According to Kennedy’s research, which is published in this month’s edition of the respected classics journal Apeiron, that code was used to hide the fact that the Athenian was a secret follower of the philosopher Pythagoras and shared his belief that the key to understanding the universe lay in numbers and math.
“Plato’s books played a major role in founding Western culture, but they are mysterious and end in riddles,” says Kennedy, a historian and philosopher of science. “In antiquity, many of his followers said the books contained hidden layers of meaning and secret codes, but modern scholars rejected this. I have shown rigorously that the books do contain codes and symbols and that unraveling them reveals the hidden philosophy of Plato.”

English scholar Jay Kennedy claims to have unlocked secret messages in texts written by Greek philosopher Plato.
Other academics aren’t quite so certain that hidden meanings lurk beneath Plato’s ponderings. “It’s not impossible in principle, but I think I would need further persuasion,” says Dr. James Warren, an expert in early Greek philosophy at Cambridge University’s Corpus Christi College. “The question is, why should it be there? And what difference does it make to our understanding Plato’s dialogues?”
Kennedy says he unwrapped the Platonic puzzle using stichometry, measuring the number of lines in the original text. Using a computer program, he was able to convert the most accurate contemporary versions of Plato’s manuscripts into their original form, which would have consisted of lines of 35 Greek characters, with no spaces or punctuation. He found that the restored texts followed a curious pattern and had line lengths involving multiples of the number 12. “The Apology,” for example, has 1,200 lines, “The Symposium” has 2,400 and “The Republic” has 12,000.
He doesn’t believe this is a coincidence, as most educated people in ancient Athens would have been aware of the importance of line counts. Scribes were often paid by the line, and, as authors often chose not to give their manuscripts titles, librarians would have labeled them according to the number of lines.
The recurring pattern, Kennedy says, chimes with the 12-note Greek musical scale, supposedly pioneered by Pythagoras. And after dividing the texts into equal 12ths, the Manchester academic found that “major turns in the argument and major concepts” matched the spacings of musical notes. In every 1,000 lines in the 12,000-line “Republic,” for example, Kennedy observed that Plato turned to the theme associated with the relevant note on the scale. Musings on love or laughter appear at the third, fourth, sixth, eighth and ninth “notes,” which were considered harmonious by the ancient Greeks. At the more dissonant fifth, seventh, 10th and 11th “notes,” meanwhile, the philosopher engaged with matters of war or death.
“As we read his books, our emotions follow the ups and downs of a musical scale,” Kennedy says. “Plato plays his readers like musical instruments.”
But the ancient Athenian wasn’t just laying down a merry tune. Kennedy argues that the code also kept him out of trouble with the Zeus-worshipping authorities. “After [Plato's teacher] Socrates was executed for sowing doubts about Greek religion, Plato had every reason to hide his commitment to a scientific view of the cosmos,” Kennedy says.
Cambridge’s Warren, though, casts doubt on that motivation, noting that Plato frequently hinted that he thought the universe was mathematically structured. In his dialogue “Timaeus,” for example, he assigns a geometric shape to the tiny particles that make up each element, claiming fire is comprised of tetrahedrons and air of octahedrons.
“My other thought,” Warren says, “is that I don’t quite know why this belief would need to be coded, if indeed it is coded. Lots of people in Plato’s time (and before and after) had surprising views about what the world was made of and didn’t all feel the need hide it.” The philosopher Epicurus, who was born around 341 B.C., argued that the gods of Olympus didn’t punish or reward humans and that the world was little more than the movement of atoms flying through an empty void.
Kennedy, though, is certain that more musical and mathematical secrets lay within the texts, and he intends to keep delving and deciphering. “‘This is the beginning of something big,” he says, noting that he has some 2,000 pages of Plato to work through. “It will take a generation to work out the implications.”

BP Oil Spill Creates a Wave of New Jobs, Takes Others Under.
Mark Wilkie is a busy guy these days, and he has the BP oil crisis to thank. Wilkie, vice president of Sebastian, Fla.-based Granite Environmental, is working full-throttle to fill his Oklahoma and Florida factories with new employees to handle the crush of orders for cleanup equipment. The company’s already hired 24 new factory workers in Oklahoma and 14 in Florida, he told DailyFinance in an email interview Friday.
While the expanding oil spill in the Gulf of Mexico is expected to impact the environment for years to come, Granite is one of a dozens of companies seeing business boom as a result. The oil spill is drawing in a boatload of orders for equipment and services to mop up the mess, and that translates to a surge in hiring for the cleanup companies.
“I know from talking with a competitor that they brought on 6 Chinese plants,” Wilke says. “As for the trickle-down effects of logistics and materials vendors, that has exponentially grown as they have had to scramble to meet demand.”
Gaining from the Spill
It’s not just companies directly involved with cleaning up the oil spill, either. Others reaping benefits from the catestropic tragedy include hotels, grocery stores, laundromats and other service providers that dot the coastal communities that line the Gulf, where cleanup staging areas have been set up. For example, the Empire Inn and Venice Inn Motel, based in the coastal Louisiana communities that bear their names, say they are seeing a wave of business from the workers involved in the cleanup.
“I’m booked up at both hotels and I’ve been trying to hire maids here since the spill,” says Melissa Taylor, an assistant business office manager for both inns. “We normally have two maids at Empire and could probably use five, and normally have four at Venice, but could use six or seven. In fact, I’ll be doing maid work at Empire because we’re short staffed. I’ve had to do that a couple times in the past month and a half.”
At this time of year, the two inns are usually only 60% full, with most rooms occupied by regular seasonal customers, such as oil-field workers and leisure fishermen taking advantage of the area’s chartered fishing trips. But now, the inns have no vacancies and 70% of their guests are involved in oil cleanup, she says.
Surrounding businesses, from barber shops to laundromats to grocery stores, are also posting more business as a result. Darren Fremin, co-owner of Fremin’s Food Market in neighboring Port Sulphur, La., is one such business. Since the oil spill, Fremin has increased his workforce to 50 employees from 40, he says.
The Cleanup Crew
As of Friday, approximately 25,000 workers have been assigned to the cleanup, including current BP employees and contractors, according to a BP spokesman. Contractors also do their own hiring for the cleanup too. On Thursday, for example, Ashland Cleaning Services interviewed 396 potential job candidates at a Louisiana Workforce Commission office in Houma, La. From that group, 392 were hired and received four hours of safety training before being shuttled 70 miles to Grand Isle, La., to report for work, says Curt Eysink, executive director with the Louisiana Workforce Commission.
And as more oil washes up on the states beaches and marshes, cleanup hiring is expected to escalate, potentially mitigating some of the joblessness that has hit particular sectors of Louisiana’s workforce. Since the oil spill, 12,000 Louisiana residents have filed unemployment claims, with most of the filings coming from the southern part of the state from folks displaced by the oil spill, Eysink said.
Those hit hardest have included sportfishing charter boat operators and related businesses, local fisherman and shellfish farmers along Louisiana’s coastline.
In an effort to pay bills, some of these boat operators are seeking work from the same company that created the record mess. In mid-May, for example, 1,113 fishermen had signed contracts with BP under its “ Vessels of Opportunity” program and another 147 were on call, according to U.S. Coast Guard Private Stephen Lehmann.
Fishing Industry Suffers
Charter fishing boats based off of Louisiana’s coast have sustained a large hit, as tourists have canceled their sport fishing trips due to the oil spill, says Louis Houvenaeghel, general manager of Delta Marina in Empire, La. He’s frustrated that so many would-be tourists assume the entire coast is closed for fishing, instead of just those areas that are actually affected. The timing couldn’t be worse: The disaster comes right as the area is headed into its peak fishing season, and Houvenaeghe says he’s having to consider layoffs as a result.
The absence of fishers is cutting into the $1.36 billion in tourism dollars that Louisiana’s nine coastal parishes contribute annually to the state’s $8.3 billion tourism industry. Those parishes provide 14,980 tourism-related jobs that add up to a payroll of $238 million, according to Jim Hutchinson, assistant secretary of the Louisiana Tourism & Cultural Department.
In an attempt to generate revenues, Houvenaeghel has spent the past 30 days sending out a constant stream of proposals to BP and other cleanup contractors to consider using The Delta Marina — with its fuel dock, hotel, restaurant and charter fishing business — as a base station for their work. He’s gotten no nibbles to date.
But Hutchinson is unenthusiastic about the idea of replacing seasonal tourists with oil-cleanup workers in any case. “This sounds good on the surface, but it’s not necessarily a good thing,” he says. “Sport fishermen aren’t benefiting and while the hotels and restaurants may be busy, if they’re turning away their regular customers, these customers may never come back, even after the oil’s cleaned up and the workers leave.

Should You Rent or Buy?
Buying a home is a rewarding experience. You derive a great deal of personal satisfaction from owning a home. Homeownership allows you to build up your personal net worth over time. Moreover, long-term increases in housing prices nationwide makes homeownership a relatively attractive investment.
In some cases, renting may be a more attractive option. For example, if you plan to move in a year or two, you are unlikely to recover the closing costs you pay when you buy a home. In addition, finding a home to buy generally takes more time than looking for an apartment to rent.
In addition to building up equity over time, owning a home offers significant tax breaks. The interest expense that you pay on up to $1 million in home mortgage debt ($500,000 if you are married and filing a separate return) is tax-deductible.
Your tax savings from the mortgage interest tax deduction are greatest in the early years of a mortgage loan. For example, on a 7%, 30-year fixed rate mortgage loan of $100,000, you pay $6,968 in interest the first year of the loan. If you are in the 25% income tax bracket, your tax savings are $1,742. In Year 16 of the loan, you pay $5,090 in interest, which saves you $1,273 in taxes. In Year 24 of the loan, you pay $2,926 in interest, which saves you $732 in taxes.
When you sell your home, you can exclude up to $500,000 in capital gains if you are married and filing a joint return. (The exclusion limit is $250,000 for other tax filers.) You will need to pass the IRS’s ownership and use tests to show that the home has been your primary residence for at least two of the past five years. In addition to mortgage interest, you can also deduct your local property taxes on your income tax return.
As a homeowner, you can tap the equity in your home in the future with a home equity loan or line of credit. Interest expense that you pay on up to $100,000 in home equity debt is tax-deductible ($50,000 if you are married and filing a separate return).
Yet, renting does have some advantages. For one, renting doesn’t require you to make a down payment, which can easily reach $25,000 or $50,000. A total monthly payment for rent is generally cheaper, too, when you include all the other costs of owing a home. In addition to paying off a loan with interest, homeowners routinely pay homeowner’s insurance and property taxes. They may also be required to buy private mortgage insurance (PMI). Finally, homeowners face maintenance and home-improvement costs that renters avoid.
In general, renting has a lower financial burden, requiring smaller monthly outlays. With the extra cash that you save each month, you may be able to invest and earn a rate of return that compensates for missed opportunities of homeownership.
Renting may be a wiser course of action if you plan to relocate to another city soon or are in uncertain financial circumstances. For persons fresh out of school or newly divorced, renting may be the only realistic option.
The above information is educational and should not be interpreted as financial advice. For advice that is specific to your circumstances, you should consult a mortgage lender or financial adviser.

This article is about Spring Break.
Spring break, also known as March break, Study Week or Reading Week in some parts of Canada, is a week long recess from studying in early spring at universities and schools in the United States, Canada, mainland China, Korea, Japan, Taiwan, Mexico, and other countries.
Time of the year
In the United States, the timing of spring break in tertiary institutions may range from the middle of March to the later part of April, but many schools are in recess for at least one of the weeks in March. Some schools call this “March break” if it occurs in a middle week in March. Other schools call it “spring recess”, or “spring recession”.[1][2][3] Many K–12 institutions in the United States coincide their spring break with Easter and Passover. In New York and Connecticut, most students have spring break in April.
Canada has a very similar practice of giving a week-long break to its elementary school and secondary schoolNew Brunswick, for example, holds their March break during the first week of March, Ontario, Nova Scotia and British Columbia, have theirs during the second or third week, while the break in Alberta usually comes in the last week of March. In the United Kingdom, the corresponding 2 weeks’ holiday are called the “Easter break” or “Easter holidays”, as it is scheduled for the weeks following and preceding Easter, and accordingly is often held in April. students in the month of March. The exact time of the month varies from province to province;
In many Canadian universities, the similar break in late February or early March is called Reading Week, and is ostensibly intended to allow students to relax from the stresses of their studies.
In Japan, the spring break starts with the end of the academic year in March and ends on April 1 with the beginning of a new academic year.
In Southern African countries like Botswana, South Africa and Lesotho, the break is held late February or early March, with University of Botswana, Lesotho, Swaziland and others coming together for a week long of games, music shows and city tourism. [2]
History
From the end of World War II until the 1980s, Fort Lauderdale, Florida, was a notorious spring break destination in the United States. It was largely made so by the efforts of one man, George Warren “Bob” Gill Jr. who was called, “the Father of Fort Lauderdale spring break.”[4] Prior to that, a few were coming to the area for a break from winter cold. On March 19, 2006, the New York Times reported that Fort Lauderdale’s reputation as a spring break destination for college students started when the Colgate University men’s swimming team went to practice there over break in 1935.[5] Fort Lauderdale became even more popular due to the 1960 film Where the Boys Are, in which college girls met boys while on spring break there.
Common practices
In locales such as Cancún or Cabo San Lucas, Mexico, spring break activities traditionally include binge drinking, recreational drug use and casual sex.[citation needed] In the past, residents of the Fort Lauderdale area have become so upset at the damage done by vacationers, that the local government passed laws restricting parties in 1985. At the same time, the National Minimum Drinking Age Act was enacted in the United States, requiring that Florida raise the minimum drinking age to 21 and causing many underage college vacationers to travel outside the United States for spring break. By 1989, the number of college vacationers fell to 20,000, a far cry from the 350,000 who went to Fort Lauderdale four years prior.[6]
Spring break party goers responded by moving to the more permissive community of Daytona Beach area (over 200,000 students traveled there each spring at its peak), but after Daytona’s local government undertook similar measures, the crowds of the mid-1990s and early 2000s had fallen to a point where “a few students still come, but officials don’t even estimate their numbers.” Panama City Beach, Florida remains a popular spring break destination due to its relative proximity to many Southern colleges and driving distances. The locals in Panama City Beach welcome Spring Breakers every year, and is a major factor in the city’s economy. South Padre Island, Texas and Fort Myers Beach, Florida are also popular Spring Break destinations among students from colleges in the south-central and midwestern parts of the country, as well as from the Northeast. One of the biggest in the Southwest, popularized by MTV is Lake Havasu City, Arizona.
Popular destinations outside the United States include Cancún, Cabo San Lucas, Acapulco, Barbados, Mazatlán, Puerto Vallarta, Jamaica, the Bahamas and the Turks and Caicos Islands. Tour agencies have not only cited the lower drinking ages in these places, but also the fact that the drinking ages are poorly enforced. Some Tour Companies put on special chartered flights for Spring Break at discounted rates.
It is common for companies to market during spring break, for instance Coca-Cola, Gillette, MTV, and branches of the United States armed forces.

Uses of radio
Early uses were maritime, for sending telegraphic messages using Morse code between ships and land. The earliest users included the Japanese Navy scouting the Russian fleet during the Battle of Tsushima in 1905. One of the most memorable uses of marine telegraphy was during the sinking of the RMS Titanic in 1912, including communications between operators on the sinking ship and nearby vessels, and communications to shore stations listing the survivors.
Radio was used to pass on orders and communications between armies and navies on both sides in World War I; Germany used radio communications for diplomatic messages once it discovered that its submarine cables had been tapped by the British. The United States passed on President Woodrow Wilson‘s Fourteen Points to Germany via radio during the war. Broadcasting began from San Jose, California in 1909,[9] and became feasible in the 1920s, with the widespread introduction of radio receivers, particularly in Europe and the United States. Besides broadcasting, point-to-point broadcasting, including telephone messages and relays of radio programs, became widespread in the 1920s and 1930s. Another use of radio in the pre-war years was the development of detection and locating of aircraft and ships by the use of radar (RAdio Detection And Ranging).
Today, radio takes many forms, including wireless networks and mobile communications of all types, as well as radio broadcasting. Before the advent of television, commercial radio broadcasts included not only news and music, but dramas, comedies, variety shows, and many other forms of entertainment. Radio was unique among methods of dramatic presentation in that it used only sound. For more, see radio programming.

A Fisher 500 AM/FM hi-fi receiver from 1959.
AM radio uses amplitude modulation, in which the amplitude of the transmitted signal is made proportional to the sound amplitude captured (transduced) by the microphone, while the transmitted frequency remains unchanged. Transmissions are affected by static and interference because lightning and other sources of radio emissions on the same frequency add their amplitudes to the original transmitted amplitude. In the early part of the 20th century, American AM radio stations broadcast with powers as high as 500 kW, and some could be heard worldwide; these stations’ transmitters were commandeered for military use by the US Government during World War II. Currently, the maximum broadcast power for a civilian AM radio station in the United States and Canada is 50 kW, and the majority of stations that emit signals this powerful were grandfathered in (see List of 50kw AM radio stations in the USA). In 1986 KTNN received the last granted 50,000 watt license. These 50 kW stations are generally called “clear channel” stations (not to be confused with Clear Channel Communications), because within North America each of these stations has exclusive use of its broadcast frequency throughout part or all of the broadcast day.
FM broadcast radio sends music and voice with higher fidelity than AM radio. In frequency modulation, amplitude variation at the microphone causes the transmitter frequency to fluctuate. Because the audio signal modulates the frequency and not the amplitude, an FM signal is not subject to static and interference in the same way as AM signals. Due to its need for a wider bandwidth, FM is transmitted in the Very High Frequency (VHF, 30 MHz to 300 MHz) radio spectrum. VHF radio waves act more like light, traveling in straight lines; hence the reception range is generally limited to about 50-100 miles. During unusual upper atmospheric conditions, FM signals are occasionally reflected back towards the Earth by the ionosphere, resulting in long distance FM reception. FM receivers are subject to the capture effect, which causes the radio to only receive the strongest signal when multiple signals appear on the same frequency. FM receivers are relatively immune to lightning and spark interference.
High power is useful in penetrating buildings, diffracting around hills, and refracting in the dense atmosphere near the horizon for some distance beyond the horizon. Consequently, 100,000 watt FM stations can regularly be heard up to 100 miles (160 km) away, and farther (e.g., 150 miles, 240 km) if there are no competing signals. A few old, “grandfathered” stations do not conform to these power rules. WBCT-FM (93.7) in Grand Rapids, Michigan, USA, runs 320,000 watts ERP, and can increase to 500,000 watts ERP by the terms of its original license. Such a huge power level does not usually help to increase range as much as one might expect, because VHF frequencies travel in nearly straight lines over the horizon and off into space. Nevertheless, when there were fewer FM stations competing, this station could be heard near Bloomington, Illinois, USA, almost 300 miles (500 km) away.[citation needed]
FM subcarrier services are secondary signals transmitted in a “piggyback” fashion along with the main program. Special receivers are required to utilize these services. Analog channels may contain alternative programming, such as reading services for the blind, background music or stereo sound signals. In some extremely crowded metropolitan areas, the sub-channel program might be an alternate foreign language radio program for various ethnic groups. Sub-carriers can also transmit digital data, such as station identification, the current song’s name, web addresses, or stock quotes. In some countries, FM radios automatically re-tune themselves to the same channel in a different district by using sub-bands.
Aviation voice radios use VHF AM. AM is used so that multiple stations on the same channel can be received. (Use of FM would result in stronger stations blocking out reception of weaker stations due to FM’s capture effect). Aircraft fly high enough that their transmitters can be received hundreds of miles (or kilometres) away, even though they are using VHF.
Marine voice radios can use single sideband voice (SSB) in the shortwave High Frequency (HF—3 MHz to 30 MHz) radio spectrum for very long ranges or narrowband FM in the VHF spectrum for much shorter ranges. Narrowband FM sacrifices fidelity to make more channels available within the radio spectrum, by using a smaller range of radio frequencies, usually with five kHz of deviation, versus the 75 kHz used by commercial FM broadcasts, and 25 kHz used for TV sound.
Government, police, fire and commercial voice services also use narrowband FM on special frequencies. Early police radios used AM receivers to receive one-way dispatches.
Civil and military HF (high frequency) voice services use shortwave radio to contact ships at sea, aircraft and isolated settlements. Most use single sideband voice (SSB), which uses less bandwidth than AM. On an AM radio SSB sounds like ducks quacking, or the adults in a Charlie Brown cartoon. Viewed as a graph of frequency versus power, an AM signal shows power where the frequencies of the voice add and subtract with the main radio frequency. SSB cuts the bandwidth in half by suppressing the carrier and (usually) lower sideband. This also makes the transmitter about three times more powerful, because it doesn’t need to transmit the unused carrier and sideband.
TETRA, Terrestrial Trunked Radio is a digital cell phone system for military, police and ambulances. Commercial services such as XM, WorldSpace and Sirius offer encrypted digital Satellite radio.

(Nov. 30) — “Twitter” has been named the “Top Word of 2009,” beating out such contenders as “vampire,” “H1N1″ and “Obama.”
According to the Global Language Monitor, a Texas company that tracks word usage on the Internet, the name of the popular microblogging Web site was the most attention-grabbing word of the year.
“In a year dominated by world-shaking political events, a pandemic, the aftereffects of a financial tsunami and the death of a revered pop icon, the word Twitter stands above all other words,” said Paul JJ Payack, president of the Global Language Monitor.
According to the group, the 10 top words for 2009 were:

Twitter, a site where users post messages of 140 characters or less, became a household word in America in 2009, with politicians, authors, comedians and everyday Americans joining in droves. But in addition to being a place where millions of users go to say what’s on their mind, Twitter proved itself to be an especially useful tool for news gathering, especially in the wake of the protests that followed the Iranian elections. It has also shown itself to be a great place to go to hear unsubstantiated rumors.
But winning the Top Word of 2009 is not, in itself, a sign of staying power. None of the top words (some of which aren’t even really words) of the past nine years was able to repeat that honor in the following one. Those are:
2008: Change
2007: Hybrid
2006: Sustainable
2005: Refugee
2004: Incivility
2003: Embedded
2002: Misunderestimate
2001: GroundZero
2000: Chad
So, congratulations, Twitter. Enjoy the honor while it lasts.
