This is the model of the balloon we will be flying

On February 26th (2200Z) until February 28th (2200Z) The Bexar Operators Group, W5BOG, will be operating from the Choke Canyon State Park, located in Calliham just west of Three Rivers, Texas, in the sheltered (cabin) area.

We will be testing a balloon launched vertical antenna about 126 feet high. It will be stabilized by four guy-cords. A special based-loaded antenna balun (4:1) has been obtained for easier antenna matching. The ground radial system will have at least 4 full sized wires with possibly more.

We will also make a determination, based upon weather conditions and the number of people assisting, to use this vertical just for transmit and use a “beverage antenna” for receive and/or increase the vertical antenna height to 252 feet so we can better compete during this “top band” event.

Two, 9 foot meteorological balloons have been purchased for this experiment, just in case we screw up with the first “flight”.    Helium tanks will be purchased close to the flight-date.    Pictures of the step-by-step antenna setup and station operation will be taken for article submission in either “QST” or “CQ” magazine.

On Wednesday, December 23, the Department of Defense (DoD) issued an Instruction concerning MARS, effective immediately.

This Instruction gives the three MARS services — Army, Air Force and Navy/Marine Corps — a new focus on homeland security and a new name: Military Auxiliary Radio System.

 The Instruction is the first major revision to MARS since January 26, 1988 — as such, the first revision since the 9/11 attacks and Hurricane Katrina, two major events that changed the way Amateur Radio dealt with emergency communications.

The DoD defines a “military auxiliary” as “an organized body of volunteers prepared to supplement the uniformed services or any designated civilian authorities by provision of specialized autonomous services when called upon or when situations warrant,” and gives the Civil Air Patrol and Coast Guard Auxiliary as examples of auxiliaries.

Checking my mail box yesterday, I was quite surprised to find an envelope from the “Heartland DX Association”.

This club runs the Nebraska QSO Party, which is held in late April each year.

See: http://www.hdxa.net/  

I had competed in this contest in 2007 and was given a certificate for top score from Texas. In 2008, I again competed but never received a reply nor were any results posted. Since I never knew what really happened, I didn’t compete in the 2009 event.

You can imagine my shock when I just received a certificate for “Tops From Texas” for the 2008 contest!   In 2010 I will compete in other state QSO events and hopefully will get rewarded with more certificates, but in a more timely manner.     You should try a few of these contests as well as they are alot of fun!
