+ On the Air: Scouts to Take to the Airwaves for the 54th Jamboree on the Air

For 2011, the WOSM organized a logo contest to choose the official logo. More than 100 logos were submitted. The winner of the contest is: Felipe Trejo Malpica from the Octavio group in Jalisco, Mexico. "The reef knot unites the world so it doesn't rip apart, especially in these times of crisis," Felipe said. "It also symbolizes the Scout Brotherhood throughout the world. In the typography of JOTA, the letter O represents radio communication; in JOTI, the letter I, a mouse represents the Internet. This idea is to graphically represent a world which uses modern means of communication to send a message of peace, unity, and of support in the face of the disasters that surround us."

Each year, more than 500,000 Scouts in more than 100 countries take to the airwaves on the third full weekend in October -- and this year will be no different. The Jamboree On The Air (JOTA) is a Scouting and Amateur Radio event sponsored by the World Scout Bureau of the World Organization of the Scout Movement. JOTA is an annual event where Boy Scouts, Girl Scouts and Girl Guides from all over the world speak to each other via Amateur Radio. Since 1958 -- when the first Jamboree on the Air was held -- millions of Scouts have met through this event. Many contacts made during JOTA have resulted in pen pals and links between Scout troops that have lasted many years. The radio stations are operated by radio amateurs, and many Scouts and leaders hold licenses and have their own stations. The majority of JOTA Scouts participate through stations operated by local radio clubs and individual hams. Read more here.

+ ARRL Briefs White House Staff on Amateur Radio's Capabilities During Emergencies

White House Cybersecurity Coordinator Howard A. Schmidt, W7HAS (left) invited the ARRL to the White House to brief staff on the part that Amateur Radio plays in Emergencies. Standing with Schmidt outside the West Wing are (left to right) ARRL President Kay Craigie, N3KN, ARRL Chief Executive Officer David Sumner, K1ZZ, and ARRL Emergency Preparedness Manager Mike Corey, W5MPC,

On September 12, at the invitation of White House Cybersecurity Coordinator Howard A. Schmidt, W7HAS, the ARRL briefed several members of the National Security Staff on the capabilities of the Amateur Radio Service to communicate in emergencies. "The White House is looking for ways that the great work of Amateur Radio operators can continue to support emergencies in the future with particular attention to increased use and dependency on Internet-based technologies," Schmidt said. The ARRL presentation, conducted by Emergency Preparedness Manager Mike Corey, W5MPC -- along with President Kay Craigie, N3KN, and Chief Executive Officer David Sumner, K1ZZ -- focused on Amateur Radio's current and evolving capabilities to provide Internet messaging connectivity.

+ Amateur Radio in Space: Take the ARISSat-1 Survey

AMSAT is inviting radio amateurs to complete a 19-question survey regarding ARISSat-1. "Please take a few minutes to answer the questions," said Steven Bible, N7HPR. "The survey results will be posted to the official ARISSat-1 website." ARISSat-1 was deployed from the International Space Station in August 2011 and is active on the following frequencies and modes:

  • 145.950 MHz FM Downlink: FM transmissions will cycle between a voice ID as RS01S, select telemetry values, 24 international greeting messages in 15 languages, as well as SSTV images. If you successfully receive the SSTV transmissions, you are invited to upload your picture to the ARISS SSTV Gallery.
  • 435 MHz - 145 MHz Linear Transponder: The linear transponder will operate in Mode U/V (70 cm up, 2 meters down). It is a 16 kHz wide inverting passband from 435.742 to 435.758 MHz and the convention will be to transmit LSB on the 435 MHz uplink and receive USB on the 145 MHz downlink between 145.922 and 145.938 MHz.
  • 145.919 MHz/145.939 MHz CW Beacons: The CW transmissions will be call sign ID RS01S, select telemetry and call signs of people actively involved with the ARISS program.
  • 145.920 MHz SSB BPSK-1000 Telemetry: The BPSK transmissions will feature a new 1kBPSK protocol developed by Phil Karn, KA9Q. When the CW2 beacon on 145.919 MHz is active, this indicates that the BPSK-1000 format is being transmitted. If the CW1 beacon on 145.939 MHz is active, the backup of BPSK-400 format is being transmitted.
+ Amateur Radio in Space: AMSAT Sponsors ARISSat-1 Re-entry Contest

AMSAT Secretary Alan Biddle, WA4SCA, said the ARISSat-1 Team is looking for entries in the Chicken Little Contest. This is your opportunity to calculate or guess when ARISSat-1 falls out of orbit. This is defined as the time it crosses an altitude of 78 kilometers, which is considered to be the point of no return. "This involves your prognostications, calculations, guesses, darts-in-the-calendar submissions for when ARRISSat-1 makes its final orbit," Biddle said. "We have a fair number of submissions from all over the world from adults, but very few from students. If you know of one who might be interested, encourage them to enter." Read more here.

+ At the Workbench: The Deadline for the Third ARRL Homebrew Challenge Is Approaching

What are you building for the Third ARRL Homebrew Challenge?

The ARRL has sponsored two Homebrew Challenges in the past, designed to test our members' design and construction skills by making useful amateur gear at low cost -- and sharing their results with our members. Our first ARRL Homebrew Challenge, announced in QST for August 2006, required the construction of a 40 meter, 5 W voice and CW transceiver built for less than $50 of new parts. The Second Homebrew Challenge, announced in February 2009, resulted in a number of creative designs of low cost 50 W linear amplifiers to follow the transceiver -- two for about $30, as well as a multiband amplifier with many features for somewhat more. The deadline for the Third Homebrew Challenge is Tuesday, November 1. Read more here.

+ ARRL Invites Nominations for 2011 International Humanitarian Award

Nominations are open for the 2011 ARRL International Humanitarian Award. This award is conferred upon an amateur or amateurs who demonstrate devotion to human welfare, peace and international understanding through Amateur Radio. The League established the annual prize to recognize those radio amateurs who have used ham radio to provide extraordinary service to others in times of crisis or disaster.

As one of the few telecommunication services that allows people throughout the world from all walks of life to meet and talk with each other, Amateur Radio spreads goodwill across political boundaries. The ARRL International Humanitarian Award recognizes the Amateur Radio Service's unique role in international communication and the assistance amateurs regularly provide to people in need.

Nominations should include a summary of the nominee's actions that qualify the individual (or individuals) for this award, plus verifying statements from at least two people having first-hand knowledge of the events warranting the nomination. These statements may be from an official of a group (for example, the American Red Cross, The Salvation Army, a local or state emergency management official) that benefited from the nominee's particular Amateur Radio contribution. Nominations should include the names and addresses of all references. Read more here.

Solar Update

The Sun, as seen on Thursday, September 29, 2011 from NASA's SOHO Extreme Ultraviolet Imaging Telescope. This MDI (Michelson Doppler Imager) image was taken in the continuum near the Ni I 6768 Angstrom line. The most prominent features are the sunspots. This is very much how the Sun looks in the visible range of the spectrum.

Tad "The Sun shines forever" Cook, K7RA, reports: Our Sun has been very active this past week, with the average solar flux rising nearly 12 points to 155.5, while the average daily sunspot numbers dropped nearly 41 points to 96.1. This implies fewer, but more intense, sunspots. A huge sunspot group numbered 1302 emerged on September 22. This was the source of a coronal mass ejection that triggered an immense geomagnetic storm. The planetary A index peaked at 67 on September 26, followed by 30 the next day and 24 on September 28. The planetary K index reached 8 for two of the three-hour reporting periods on September 26, indicating an intense geomagnetic storm. The resulting aurora was observed in many places, including Maine, Massachusetts, Michigan, Minnesota, New York, North Dakota and South Dakota. On September 22, there was a major X1.4 class solar flare at 1100 UTC, with a large CME, but this was when sunspot 1302 was just coming over the horizon, so it wasn't Earth-directed. On September 24, sunspot group 1302 produced a larger X1.9 flare. Currently, the latest forecast from NOAA/USAF has solar flux for September 29-October 7 at 130, 130, 125, 120, 120, 115, 110, 110 and 140, and then 145 on October 8-10 and 140 on October 11-17. The predicted planetary A index is 12, 5 and 8 on September 29 through October 1, then 5 on October 2-7, then 8, 15, 12 and 8 on October 8-11 and 5 on October 12-21. Look for more information on the ARRL website on Friday, September 30. For more information concerning radio propagation, visit the ARRL Technical Information Service Propagation page.
