Today, GNURadio enthusiasts are in the same situation as radio electronics enthusiasts about 90 years ago: Many ideas sound very promising, but international regulations and national laws prohibit extended experimenting. Radio Amateurs such as Nobel Price winner Joe Taylor (K1JT) have demonstrated that digital signal processing allows moonbounce transmissions also to the private hacker, but also many more thrilling experiments such as airplane scatter and the active use of Amateur Radio satellites. Most, however, require a little more power than those 10 dBm produced by the USRP series. This talk shows how easy it is to make use of the definitions of international Amateur Radio regulations as part of the ITU ruleset and how to get a license according to national laws - and to experiment with GNURadio -and- with high power.
