Eye on Awards : The IARU Region 2 Award

In October 2009, IARU Region 2 announced a new award -- the IARU Region 2 Award -- available to amateurs and shortwave listeners who submit confirmed QSLs with 20 Region 2 countries or entities. To be considered for the award, contacts must have been made after April 16, 1964 -- the date when IARU Region 2 was founded. Read more here.

Hints and Kinks: Unistrut Antenna Support

This idea comes to us from Louis Kobet, WB3DZD, of Camas, Washington.

When considering a center support for the installation of an inverted V antenna I decided on the following requirements: a strong material, easy assembly, corrosion resistant and with tilt-over capability. The initial design was to use several 10-12 foot sections of antenna mast or 2 inch galvanized pipe coupled together. Due to the cost of antenna mast and galvanized pipe being more than anticipated, an alternative, 10 foot sections of 1-5/8 inch Unistrut channel was selected.

Figure 1: The PVC pipe and hoist pulley device mounted to the top of the Unistrut for hoisting the antenna.

Unistrut is a ham's Tinkertoy. It is available in 13/16, 1 1/4 and 1-5/8 inch widths, 10 and 20 foot lengths and in 12, 14 and 16 gauge sizes. It is made with dipped surface protective treatments from electro-deposition acrylic green to "hot dipped" galvanized coatings and multiple channel designs (including telescoping sections). A vast selection of brackets and fasteners is available and it is continuously slotted for easy guying. The design and choices for project use are limited only by the creativity of the user.

The tilt over base support consisted of a treated 4×4 inch landscape post anchored in concrete. (The wooden post was moisture sealed at the top using the dipped coating used for hand tools and along the length with several coats of wood sealer.) The Unistrut mast pivot point on the support base was a 3 inch lag bolt about 50 inches above ground. In retrospect, a section of Unistrut could have been set in the concrete as the antenna base support.

The Unistrut mast preparation consisted of black paint (except for areas where the sections were bolted together) and the addition of a hoisting pulley mounted at the end of a 2 foot PVC pipe (see Figure 1). One problem encountered was in bolting the Unistrut together. Bolting back-to-back against the base of the "U" was not possible because I couldn't get a socket on the bolt head inside the Unistrut channel. To get around this the Unistrut was bolted with the open "U" ends face to face. Square Unistrut channel would have eliminated this issue. The three Unistrut sections were bolted together with about a 12 inch overlap.

Figure 2: The center of the inverted V raised into position at the top of the Unistrut support.

An antenna hoisting line was fed through the pulley and mast section carried to the base support for mounting. After attaching the mast to the pivot point it was tilted up into position, plumbed and secured in place with three additional lag bolts.

The V antenna was spread out, transmission cable attached and hoisted to the top of the mast. The ends of the V antenna were attached to a 12 foot landscape treated 4×4 that was secured to the property fence.

ITU News: ITU Digitizes Historical Archives

The International Telecommunication Union (ITU) announced on February 11 that they have launched the History of ITU portal. This program -- the digitizing of the ITU's archive of historical documents -- aims to improve access to information on the ITU and chart its evolution since its establishment in 1865, while ensuring the long-term preservation of historic documents. The archives will be freely accessible. ITU's Historical Documents Digitization Program is an ongoing project to catalogue and scan key ITU documents and outcomes of major conferences and make them available on the web. Optical character recognition (OCR) allows the documents to be fully searchable. Documents generated from ITU Plenipotentiary Conferences -- as well as from early radio, telegraph and telephone conferences -- are now available on the portal. The portal provides background information, key data and links to the documents and other materials for each conference. The digitization program will continue to make available documents of historic significance, including those related to Radiocommunication Conferences since 1903.

Silent Key: Chris Walters, N0HVK, Killed in Connecticut Explosion

Chris Walters, N0HVK (SK)

Chris Walters, N0HVK, of Florissant, Missouri, was killed in an explosion on Sunday, February 7. He was 48. Walters -- who was employed as a safety manager for an electrical subcontractor at the Kleen Energy Plant in Middletown, Connecticut -- was one of five men killed in the explosion; at least a dozen were injured. The accident received national news coverage. According to officials, the plant was in the process of doing a "blow down" -- clearing the natural gas lines -- when the explosion occurred, but investigators are still determining the cause of the explosion. According to his wife, Fran, Walters was unemployed in Missouri and had been in Connecticut for two months working a temporary job. While in Connecticut, Walters found time to enjoy Amateur Radio activities. He was a member of the Shore Point Amateur Radio Club (SPARC), volunteering for community events and fundraisers with the club; he was also part of SPARC's first ARRL Field Day. Connecticut Governor M. Jodi Rell requested that flags fly at half-staff on February 10 in honor and memory of the five men who perished in the explosion. -- Some information provided by WVIT and SPARC

Solar Update

No, you don't need to clean your monitor -- those are sunspots! The Sun, as seen on Thursday, February 11, 2010 from NASA's SOHO Extreme Ultraviolet Imaging Telescope.

Tad "Light breaks where no Sun shines" Cook, K7RA, reports: The increasing sunspot activity continues, and images from NASA's STEREO mission show a string of active regions in the Sun's northern hemisphere -- both visible and over the horizon on the far side. The high sunspot number for the week was 71 on February 8; the average for the week was 43.3. We haven't reported a weekly average that high since the week of March 27-April 4 in 2008 when it was 43.6. The daily sunspot number hasn't been as high as 71 since May 28, 2006 when it was 78. The earlier reading that reached that level or more was 105 on April 6, 2006. On February 8 -- when the daily sunspot number was 71 -- the total area covered by sunspot activity was 460 millionths of a solar hemisphere. That number hasn't been as high since the same earlier week in 2008 that had a high sunspot number average. The dates were March 26-27 when the area of sunspots was 520 and 510. Look for more information on the ARRL Web site on Friday, February 12. For more information concerning radio propagation, visit the ARRL Technical Information Service Propagation page.
