Students Call Space Station With Home-Built Radio 330
Pizzutz writes "Four Toronto college students have accomplished a technological feat that their teachers are calling a first. The Humber College seniors made contact with the International Space Station Monday with a radio system they designed and built themselves. School officials say that, to their knowledge, that's never been accomplished by students at the college level." Somewhat disappointingly, the students actually did have permission to make contact.

I understand how the story would be more romantic if they contacted the ISS out of the blue (imagine how surprised those aboard the station would be!). But the fact of the matter is that living in space is precarious at the best of times. Unexpected events, especially those that tie up communication channels, are unsafe and not welcome. Thus the students did the right thing by clearing permission first, and they should be applauded for that.
Also, the students probably wanted their signal to actually be answered, rather than ignored or (even more likely) simply not noticed!

This is not exotic technology. NASA has a program devoted to doing this in high schools. [nasa.gov]
From their blog, the only big problem was getting permission to go on the roof of a building (a large flat roof) to put up the antenna. If they'd just headed out to an open field (they're using a radio intended for car installation, after all), mounted the antenna on a tripod, and aimed it by hand, they probably could have completed the project in a week.
Hams talk to the ISS all the time. When it's visible, it's only a few hundred miles away, after all. The only real problem is booking some astronaut time.
