+ Public Service: Ham Radio Operators Assist in Catalina Island Rescue

Around 9:45 on the night of October 23, while attending an overnight event at the Boy Scouts' Camp Emerald Bay on Santa Catalina Island, Karl Tso, KI6PCW, and his wife, Deborah Ava, KJ6CRZ, of Topanga, California, decided to climb a hill to check out the view -- and to see if they could get into the repeater on the island with their handheld transceivers. As they climbed the hill, the two radio amateurs heard a sound; Tso turned his high-powered flashlight on the source, only to discover a man who had fallen 48 feet to the rocks below, bleeding and severely injured.

+ ARRL Recognizes: George E. Smith, AA2EJ, Wins Nobel Prize

Nobel Laureate George E. Smith, AA2EJ. Smith received the 2009 Nobel Prize in Physics for his invention of the charged-couple device (CCD).

Around 5:30 on the morning of October 6, George E. Smith, AA2EJ, of Barnegat, New Jersey, got a phone call that changed his life: He had just found out he had won the Nobel Prize in Physics for 2009 "for the invention of an imaging semiconductor circuit -- the CCD sensor." Smith will share the prize money with two other recipients: Charles K. Kao, of Standard Telecommunication Laboratories in the United Kingdom and Chinese University of Hong Kong, and Willard S. Boyle, of Bell Laboratories. Each recipient will receive a diploma, a medal and a document confirming their share of SEK 10 million (about $1.4 million); Kao will receive 50 percent, while Smith and Boyle will each receive 25 percent of the monetary award.

Kao was recognized by the prize committee for his "groundbreaking achievements concerning the transmission of light in fibers for optical communication." His discoveries paved the way for optical fiber technology, used for almost all telephony and data communication today. Boyle and Smith invented a digital image sensor -- the CCD -- that has become an electronic eye in almost all areas of photography.

"My wife Janet, AA2EI, and I sailed around the world for 17 years," Smith told the ARRL. "While we were on our boat, we used Amateur Radio, especially in the South Pacific. Janet was the principal radio operator. With our radio, we could keep track of other boats in the area. Over in the Southwest Pacific, there are shore stations there that provide weather forecasts every day on the ham radio. We would listen for these, as it was such a tremendous help for us as sailors."

This very first CCD prototype was pieced together months after Smith and Boyle laid out its working principles.

The CCD -- invented in about an hour over lunch when Smith and Boyle worked at New Jersey's Bell Labs -- was, according to Wired Magazine, the first practical way to let a light-sensitive silicon chip store an image and then digitize it. In short, it is the basis of today's digital camera. According to Wired, the "most amazing thing about the invention" is that Boyle and Smith came up with the design so quickly. With Bell Labs threatening to take the funds from their department and transfer the money to other research, Boyle had to come up with a competing semiconductor design. He got together with Smith, and within an hour, they came up with the idea and sketched it all out on a blackboard.

"One morning in October, 1969," Boyle wrote on his Web site, "I was challenged to create a new kind of computer memory. That afternoon, I got together with George Smith and brainstormed for an hour or so on a new kind of semiconductor device, drawing a few sketches and equations on a blackboard. We called it a charge-coupled device: A 'CCD.' When we had the shops at Bell Labs make up the device, it worked exactly as expected, much to the surprise of our colleagues."

When asked by the ARRL how he felt about winning the Nobel Prize, he exclaimed, "I feel great! Even though there's a lot of nonsense to go through with it, it's worth it and winning it does wonders for your ego. Aside from the initial shock and having to go through piles of mail, e-mail and returning telephone calls, I know that will calm down. As for the long-range future, I'm getting many invitations to give talks. Next year, I've been invited to speak at a major conference in Seoul, South Korea, another in Portland Oregon and another in Switzerland. I've been invited to France to give a talk, China, too. We need to sit down with a calendar and figure it all out. Having a Nobel makes a big dent in your lifestyle."

Smith told the ARRL that he knew the CCD was under consideration for the Nobel Prize, "but we didn't know exactly if, or when, it would happen. Research that wins the Nobel is often done many years beforehand. In my case, this was 40 year old research. The Prize Committee wants to make sure the research has stood the test of time.

Without CCDs, this image -- taken by the Hubble Space Telescope in 2002 showing "light echos" illuminating the dust around supergiant star V838 Monocerotis (V838 Mon) -- would not be possible. V838 Mon is located 20,000 light-years away on the periphery of our Galaxy. In early 2002, it increased in brightness temporarily to become 600,000 times brighter than our Sun.

"Amateur Radio has always attracted individuals who want to understand and exploit nature's laws," fellow Nobel Laureate Joe Taylor, K1JT, told the ARRL. "These are essential characteristics for first-rate scientists, as well. The 2009 Nobel Prize in Physics honors the invention of an imaging semiconductor circuit -- the CCD sensor used in digital cameras, the Hubble Space Telescope and many other scientific and consumer devices. It was no great surprise to learn that one of the Laureates, George Smith, is also a radio amateur." Taylor was awarded the Nobel Prize in Physics in 1993 "for the discovery of a new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation."

Next month, Smith will travel to Stockholm, Sweden for the award ceremony on December 10. It is certain that his picture will be taken scores of times by the international media, made possible through the technology that he and Boyle pioneered.

+ Operating: Fall Frequency Measuring Test This Month

The W1AW Frequency Measuring Test (FMT) has taken several different formats over the past few years. This year, we return to the "classic" FMT -- measuring the frequency of an unmodulated carrier. Accurate frequency measurement is required of all hams for both regulatory compliance -- "stay in the band!" -- and operating convenience, particularly on the new digital modes. The W1AW FMT will run on November 12, 2009 at 0245 UTC (this is Wednesday evening, November 11, 2009 at 9:45 PM EST). It will replace any W1AW bulletin normally scheduled for that time. It is recommended that participants listen to W1AW's transmissions prior to the event to get an idea of conditions to see which band (or bands) will be best for measurement purposes. Read more here.

+ MARS: MARS Cuts Ribbon on New Pentagon Station

A military institution designed to provide emergency communications has moved to new quarters in the Pentagon. On October 21, John G. Grimes, the former Assistant Secretary of Defense for Networks and Information Integration, cut the ribbon on the new Military Affiliate Radio System (MARS) station, now located on the fifth floor of the Pentagon. The facility -- manned by the Pentagon Amateur Radio Club (PARC) -- is packed with amateur radios, radiotelephone patches, computers and data links. "This is a great facility, manned totally by volunteers," Grimes told the crowd who came to see the new station. "It's a crucial capability for our country." Read more here.

Now You Know!: Hiram Percy Maxim and the W1AW Station

More than 1000 visitors come to see ARRL and operate W1AW each year. Each visitor has a chance to tour ARRL HQ and meet and talk with staff, and see all that the League does to promote the Amateur Radio Service. When they go over to W1AW, some guests want to know if the station was once the home of Hiram Percy Maxim, cofounder and first President of the ARRL.

The July 1920 edition of QST featured Maxim's house on its cover. Click here to read a description of the 1AW station.

In February 1936, when Maxim died of pneumonia on his way back from visiting Lick Observatory on Mt Hamilton in San Jose, California, the ARRL HQ station -- W1MK -- was located at Brainard Field in Hartford. In March 1936, the Connecticut River flooded and the building where the station was housed was destroyed by the flood waters. The League's Board of Directors decided that a new station be built on a more suitable site in memory of Maxim. In December 1936, the FCC -- in the first action of its kind -- assigned the call W1AW to ARRL in memoriam. The ARRL purchased a 7 acre site in Newington, about 5 miles southwest of Brainard Field. From the flood until September 1938, W1MK operated from ARRL Headquarters, then on LaSalle Road in West Hartford. On September 2, 1938 -- what would have been Maxim's 69th birthday -- W1AW, the Hiram Percy Maxim Memorial Station, was dedicated, with the ceremony broadcast across the country by CBS Radio. So, no, the building where W1AW is located was never home to Hiram Percy Maxim; in fact, he never saw it. But even so, we know that his spirit lives on every time we sit down at a radio. Now you know!

Do You Know?: A Trivia Answer for Our Readers

Last week, ARRL News Editor S. Khrystyne Keane, K1SFA, told ARRL Letter readers about the long and proud history of the ARRL Sweepstakes, mentioning that at one point, The Philippines was a multiplier in the Sweepstakes, as was Cuba (as part of the West Indies Section). We wondered what years that The Philippines and the West Indies Sections ceased to be multipliers in Sweepstakes. Unfortunately, we didn't receive any correct answers. The Philippines was no longer a Section as of 1946 and in August 1988, two new Sections -- Puerto Rico and US Virgin Islands -- replaced the West Indies Section (Cuba disappeared from the West Indies Section in 1940). Thanks to everyone who sent in answers. Look for another trivia question in a future edition of The ARRL Letter.
