@_elena well, next time you come to FOSDEM, feel free to drop by the amateurradio infobooth and will show you all the geekyness and fun radio-technology has to offer.
Usually we are in the AW building. (Can't miss it, it the building with the large radiomast in front of it 
)
But, as Michael also mentions below, be carefull, as once you enter the wonderfull and sometimes magical world of radio technology and mesh* networking, there is no way going back. 
Enjoy the ride!
