ARRL Field Day: ARRL PR Committee to Host Field Day Webinar


The ARRL Public Relations Committee will be holding a free webinar entitled Field Day Press Release on Thursday, April 12 at 9 PM (EDT). This webinar is geared for those who want to learn the easiest — and most effective — ways to write up a media release for Field Day and actually get it noticed by the media in your home region. Learn the “tricks of the trade” from the people who actually work in radio, television and print media. ARRL Public Relations Committee Chairman Steven Polunsky, W5SMP, will host the event; Polunsky is also the Public Information Coordinator for the ARRL’s South Texas Section. Joining Polunsky are Bill Husted, KQ4YA (print), Mark Kraham, W8CMK (TV) and Don Carlson, KQ6FM (radio). Space is limited — reserve your spot today.

On the Air: Amateurs Must Protect New Radars in 23 cm Band


The Federal Aviation Administration (FAA) is deploying a new generation of Common Air Route Surveillance Radar (CARSR) that has some implications for the use of the 1240-1300 MHz (23 cm) band by amateurs. The Amateur Service allocation in this band is on a secondary basis, with aeronautical radionavigation and several other services primary in the United States Table of Frequency Allocations. The FCC rules require that amateur stations operating in the 23 cm band may not cause harmful interference to stations in the radionavigation-satellite service, the aeronautical radionavigation service, the Earth exploration-satellite service (active) or the space research service (active). One case of harmful interference in Southern California has been reported.

CARSRs are being installed in several dozen locations throughout the country and will use various frequencies in the 1240-1350 MHz range with an occupied bandwidth of about 3 MHz. In the vicinity of the radars, amateur operation may be precluded in a portion of the 23 cm band. The ARRL is in contact with FAA engineers. We anticipate that the constraints on amateur use of the band will be limited to those necessary to protect aviation safety, which of course cannot be compromised.

April 18 Is World Amateur Radio Day

Read by: RICK N9GRW

The year 2012 marks the 87th anniversary of the founding of the International Amateur Radio Union (IARU). To mark this occasion, the IARU and its more than 160 Member-Societies will celebrate World Amateur Radio Day on April 18. For many years, the IARU has declared a theme for each World Amateur Radio Day. The theme for 2012 is Amateur Radio Satellites: Celebrating 50 Years in Space in remembrance of the launch of OSCAR 1 on December 12, 1961 and the launch of OSCAR 2 on June 2, 1962.

The Founding of the IARU

In 1924, ARRL President Hiram Percy Maxim, W1AW, had scheduled a business trip to Europe. While in Europe, Maxim was asked by the ARRL Board of Directors to represent the ARRL in fostering international relations between amateurs. This, of course, he was delighted to do.

Following the informal meeting in 1924, representatives from France, Great Britain, Belgium, Switzerland, Italy, Spain, Luxembourg, Canada and the United States formulated a plan to hold an International Amateur Congress in Paris, France in April 1925 for the purpose of founding the IARU. Representatives from Europe, North America, South America and Asia attended the Congress, adopting a constitution for the IARU on April 17. At a closing assembly on the following day, officers were elected and the actions of the Congress ratified by representatives from 25 countries. Thus, April 18 became the official “birthday” of the IARU and is now designated World Amateur Radio Day.

Today, just as Maxim and his counterparts envisioned, the IARU is an international confederation of national Amateur Radio organizations that allows a forum for common matters of concern and collectively represents matters to the International Telecommunication Union (ITU).

A Brief History of Grape Growing and Winemaking in Tennessee


During the late 1800s, vineyards were flourishing in Tennessee, mostly in areas that were believed to be unsuitable for other agricultural uses. At the time, it appeared that grape-growing would become one of Tennessee’s most important cash crops. However, Prohibition all but ended this promise in 1919. It is just within the last quarter of the 20th century that grape growing (and winemaking) has seen a remarkable recovery.

In 1973, seven individuals interested in viticulture and oenology gathered around a kitchen table in Clarksville and organized The Tennessee Viticultural and Oenological Society (TVOS.) From this small beginning, TVOS membership has grown by leaps and bounds and includes both amateur and commercial grape growers and winemakers.

The Tennessee Farm Winegrowers Alliance (TFWA) was formed to promote the sales of Tennessee wine and to facilitate the relationship between Tennessee farmer grape growers and wineries. The result has become a major agri-business in Tennessee.

Now TFWA and TVOS work together to coordinate and advance the efforts of all Tennessee grape interests, including promotion, information, and legislation.
