Bragging Rights

I recently discovered this audio clip of Col. Doug Wheelock aboard the International Space Station, recognizing my call sign (K5JAW) during an overpass of the United States on November 7, 2010.  The ISS maintains an amateur radio station, and is on the air frequently.  It's a challenge to have relatively weak earth-based signals heard aboard the ISS, orbiting about 200 miles above the surface of the earth.  Of course, being that high, it's relatively easy to hear their signals.  I've heard them on a number of previous passes, but this was my first confirmed contact.
