On Sunday, October 12, Richard Garriott W5KWQ from Austin, TX became the sixth private citizen to fly with the Russian Federal Space Agency (RKA) for a mission on the International Space Station (ISS). Richard is following in the footsteps of his Dad, astronaut Owen Garriott, W5LFL, who was the first amateur radio operator to have a QSO from space. Richard docked with the ISS on the 14th, two days after launch.
Garriott, a successful video game industry professional, had numerous scheduled contacts planned during his trip including those with several schools, amateur radio friends and even the Mayor of Austin. In the end his flight provided a unique opportunity for ground stations to make contact via amateur radio with someone who had more time for contacts than “professional” astronauts aboard the ISS typically do. That being said, there was a rapidly growing number of amateur radio operators vying to log a contact with W5KWQ and the International Space Station Amateur Radio Club, NA1SS.
On Saturday, October 17th while attending the weekly Charro Amateur Radio Club meeting in Brownsville, my attention turned to satellite and space communications while discussing Richard’s mission with K5REW. Ric shared his past experiences with space shuttle communications and provided several helpful tips. My ongoing interest in actively working satellites must have been sufficiently energized since by Sunday morning I was up early to attempt my first space contact… And there he was, as clear as day– and right on time! Somewhat surprised at how clear he was coming in, I figured, this must be just as easy as many say it is: “you can work the ISS with a 3 or 5 watt HT and even get away with just using the rubber duck antenna the radio comes with”. So, with that in mind, I dropped the power on my base station ICOM IC-220H and called… And called.. and called… And yes, called some more. Helloooo?
To my dismay, he was acknowledging stations in Houston and Dallas, but what about me or others in the Valley? Later that afternoon I caught the tail end of a QSO he was having as I started my car- Gave my call but again, too late. Later that day Jerry KB5TMC sent an e-mail with some slow scan TV images that Richard had transmitted. Jerry’s e-mail motivated me further…. I reeeeeally wanted to do this now.
I dusted off a small three element Arrow Yagi and fashioned it for use with my mobile. Next, I went on a field trip at the crack of dawn to Port Isabel figuring that I would do better there at reaching the Southern Gulf of Mexico just above the horizon than from my home QTH in Los Fresnos. I also had a “plan B”. If initial attempts failed, I could drive across the Queen Isabella bridge and, if timed just right, should have an unobstructed path while atop the bridge. Well I gave it a go and resorted to “Plan B” but still no success.
Not being known as a person that easily gives up I took a better look at the remaining pass trajectories for that day. A later morning pass attempted from home yielded no improvement. I figured that my best remaining chance would be to attempt a contact while he was a high overhead as possible– not near the horizon. There was one such attempt that afternoon. I waited and tried but I did not even hear Richard at all, even as he was tracked pretty much over head…. Maybe he was taking a nap or conducting some top secret experiment? His mission would soon be over and how could we have him fly over the Valley without at least saying “Hola”? Wednesday morning would put him following the path of an arc over the RGV once more… This attempt had to count.
I decided to give it a go from home this time, watching his trajectory on my computer while using an Alinco DR135 and the same Yagi. The plan was to aim the antenna at the ISS through his trajectory and follow his path as best could be accomplished manually. It was a clear morning with very few clouds and the stars made quite an impressive backdrop to “my mission”. This time I began transmitting my call at about 30 seconds before I anticipated his being in range, figuring if he heard me first, I might have an edge. At 11:23:44 UTC he was commencing his pass. I called a couple of times, no Richard. Then… Two minutes later at 6:25 Central Time… Eureka! “This is Richard W5KWQ aboard the International Space Station; station in Los Fresnos, Texas please call back.” Could it be? “This is AB5JO in Los Fresnos, TX, just want to congratulate you on your flight and wish you a safe trip home”. “We are starting to prepare for the trip back now. Good contact, thank you.” And, as quickly as our contact began, he was no longer heard.
How cool, I thought. Hey, one for the Valley. Thinking back, Ric and Jerry motivated me enough to “Just do it” and although I was getting more and more suspicious of my success, I was getting equally as determined. As it has been proven time and time again with Ham Radio, ingenuity, determination and an unobstructed path– and the proper antenna go a long way. Hope this motivates you to go out and do something you have been meaning to do.
For now, I have to get to mowing my lawn!
73,
Joe
