Just found a link with info on listening to audio from the Space Shuttle on your ham radio: http://www.amsat.org/amsat/sarex/shutfreq.html (145.460 MHz in Boulder). I'll have to try it out. I've been a little lax on turning on the radio lately.
My primary reason for getting my ham license was for storm chasing. I wanted to be able to report in and warn people of dangerous weather. I've been a member of SKYWARN for a number of years, but seem to be under deadline at work when the best storms come up!
I've always wanted to talk to the Shuttle or ISS, so I'll have to try it some time.
