In areas where cell phone signals just won't work, Amateur Radio gets through. That's what Brent Yeates, KA7FAP, of North Logan, Utah, found out just before noon on Wednesday, December 2: He came across a dairy truck that had crashed and rolled over in the Logan River as he drove on Route 89 through Logan Canyon. As 38,000 pounds of dairy products were spilling into the Logan River, Yeates waded through the cold river to help get the driver out of the truck's cab and then put out a call on his handheld transceiver.

+ Spotlight on Amateur Radio: Major Computer Publication Devotes January 2010 Issue to Amateur Radio

Emergencies may get all the attention in the press, but lately, the technological side of Amateur Radio has been showing up a lot in places that are read by the people who make next year's trends. Hams indeed are technical and creative people, consummate MacGyvers. To kick off the new year, the computer magazine Linux Journal has come out with an entire issue dedicated to Amateur Radio and the creative uses of open source computer programs. This 80 page issue features Tux, the Linux mascot on its cover wearing a pair of headphones, holding a microphone -- and even sporting an Emergency Coordinator badge around his neck -- hooked up to an HF transceiver. The issue has headlines on the cover such as "Amateur Radio and Linux -- Open Source for the New Generation," and "Get Started with Amateur Radio," and includes articles like "When All Else Fails -- Amateur Radio, the Original Open-Source Project" by David Lane, KG4GIY.

+ Scott Robbins, W4PA, to Purchase Vibroplex

Scott Robbins, W4PA, of Knoxville, Tennessee, told the ARRL that he has signed an agreement to purchase The Vibroplex Company, Inc from present owner Felton "Mitch" Mitchell, W4OA, effective December 21, 2009. "Vibroplex represents the great tradition of CW operation in Amateur Radio going back many, many years," Robbins told the ARRL. "I'm tickled to be able to continue the more than 100 years of history that has gone into this company." Robbins -- who has been employed with Ten-Tec Inc since 1995 (he has been Product Manager for Ten-Tec's Amateur Radio equipment line since 1997) -- will leave his position in mid-December to take over full-time management and ownership of Vibroplex. "It's a great opportunity to continue the more than 100 years of tradition that the Vibroplex name represents," Robbins said. Read more here.

+ Organizational: Marc Tarplee, N4UFP, Appointed South Carolina Section Manager

Marc Tarplee, N4UFP, of Rock Hill, has been appointed the new ARRL South Carolina Section Manager. He will complete the term of Jim Boehner, N2ZZ, who was elected ARRL Roanoke Division Vice Director last month. When Boehner announced that he was stepping down from the Section Manager post he has held since January 2003, he recommended Tarplee, the South Carolina Section Technical Coordinator, for the position. Tarplee and Boehner both take on their new positions January 1, 2010. According to the Rules and Regulations of the ARRL Field Organization, when a vacancy in the office of Section Manager occurs between elections, the position is filled by appointment by the Membership and Volunteer Programs Manager in consultation with that Division's Director. MVP Manager Dave Patton, NN1N, consulted with Roanoke Division Director Dennis Bodson, W4PWF. Tarplee has been South Carolina's Technical Coordinator for almost seven years, first appointed by Boehner in January 2003. Tarplee's term of office as Section Manager will continue through December 31, 2010.

The Doctor Is IN: Focusing on 10 Meters

By ARRL News Editor S. Khrystyne Keane, K1SFA

Now with the ARRL 160 Meter Contest come and gone, it's time for me to focus on the opposite end of the HF spectrum: 10 meters. You guessed it -- I'm gearing up for the 37th running of the ARRL 10 Meter Contest. This contest has a bit of a twist to it: Operators have the choice of using CW only, SSB only or they can mix it up and use both. So as I prepare this week for the 'test, I went to ask the Doctor what is so special about 10 meters. Is there anything I need to be aware of and watch out for this weekend? Check up on what the Doctor has to say here.

+ Regulatory: FCC Dismisses Two Petitions

On Wednesday, December 9, the Federal Communications Commission dismissed two separate Petitions for Rulemaking. The first Petition was filed by Murray Green, K3BEQ, concerning the operation of repeater stations in the Amateur Service. The other Petition, filed by Glen Zook, K9STH, requested amending Section 97.119(a) to change how often stations must identify themselves. Read more here.

+ Now You Know!: The ARRL 10 Meter Contest and Satellites

By ARRL News Editor S. Khrystyne Keane, K1SFA

This weekend marks the 37th running of the ARRL 10 Meter Contest. Back in November 1973 when the contest was first announced in QST, the rules differed slightly from how they stand now. This event began due to the interest that radio amateurs showed in the 10 meter band, thanks to the 5-band awards offered by the ARRL. "Occupancy is an important issue of the day as is proof that there's life in the old band yet," the article stated. "At a recent convention the matter was raised and met with enthusiastic response. Rather than postpone the idea for another year, the consensus was 'let's give it a try for '73,' prompting a recommendation by the Contest Advisory Committee."

AMSAT-OSCAR 6 was launched October 15, 1972 by a Delta 300 launcher from Vandenberg Air Force Base, Lompoc, California. AO-6 was launched piggyback with ITOS-D (NOAA 2). AO-6 was the first-phase 2 satellite (Phase II-A). Weight 16 kg. Orbit 1450 x 1459 km. Inclination 101.7 degrees. Box shaped 430 x 300 x 150 mm. Quarter-wave monopole antennas (144 and 435 MHz) and half-wave dipole antenna (29 MHz). AO-6 Firsts: complex control system using discrete logic; satellite-to-satellite relay communication via AO-7; demonstrated Doppler-location of ground station for search and rescue, and demonstrated low-cost medical data relay from remote locations. Click here for more information on AO-6. [Image and information from AMSAT]

In 1973, each completed two-way QSO was worth 2 points, except QSOs with a US Novice were worth double that. The article pointed out that certain FCC-issued Novice call signs look a little strange: "Novices in KZ5 and KG4 have strange call signs -- a Canal Zone Novice has an 'N' at the end of the call, such as KZ5AAN. A Novice in Guantanamo Bay has an 'N' after the number, such as KG4NAA. All others replace the K with a W (i.e. WL7, WH6, etc.). If you work a station once on cw you can work him again on phone. Oscar QSOs also count."

Oscar QSOs? As in the satellite? Yes! The 1973 rules stated that "Oscar 6 contacts may be counted. All cw QSOs must take place between 28.0-28.5 MHz except those made though Oscar 6." The article also advised contest participants to stay clear of 29.45-29.55 MHz, as these were the Oscar downlink frequencies. Beginning in 1973 and continuing through 1979, QSOs made via the Oscar satellites counted for credit in the ARRL 10 Meter Contest. Beginning in 1980, after 10 meters had seemingly come back to life, the CAC no longer accepted the QSOs for credit in the contest. Now you know!

+ Silent Key: Ambassador William A. Wilson, K6ARO (SK)

Bill Wilson, K6ARO (SK)

William A. "Bill" Wilson, K6ARO -- the first US Ambassador to the Holy See (the Vatican) -- passed away from cancer early on the morning of Saturday, December 5. He was 95. First appointed as presidential envoy to Rome in 1981 by President Ronald Reagan, Wilson was appointed the first full ambassador to the Holy See in 1984, once official relations were established, serving until 1986.

Solar Update

The Sun, as seen on Thursday, December 10, 2009 from NASA's SOHO Extreme Ultraviolet Imaging Telescope. This image was taken at 171 Angstrom; the bright material is at 1 million degrees Kelvin.

Tad "When I behold, upon the night's starr'd face" Cook, K7RA, reports: Finally! A sunspot appeared on Wednesday, December 9, giving us a daily sunspot number of 13 -- this followed 16 days of no sunspots. The new group is number 1034, and need we say it is a Solar Cycle 24 spot? Cycle 24 spots were news at one time, but we haven't seen a Solar Cycle 23 spot since number 1016 on April 29-30, 2009. Solar Cycle 23 peaked around 8-9 years ago. Excitement builds for this weekend's ARRL 10 Meter Contest. Will sunspot activity amount to enough to enhance 10 meter propagation? The latest prediction shows a rising solar flux, 74 and 75 on December 10-11 and 77 from December 12-16; this must correspond to the new sunspot swinging into view, instead of peeking over the horizon as it did on Wednesday. Even without sunspots, Geminids meteor showers have intensified with each passing year as Earth moves deeper into the debris stream from extinct comet 3200 Phaethon. The predicted peak of the meteor shower is about five hours after the end of the contest and there is a good chance that ionized comet trails could enhance 10 meter propagation this weekend. Look for more information in the Solar Update, available on the ARRL Web site on Friday, December 11. For more information concerning radio propagation, visit the ARRL Technical Information Service Propagation page. This week's "Tad Cookism" brought to you by John Keats' When I Have Fears That I May Cease to Be.
