@_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!
