HAMlib registered version is the same as the freeware version, except for that there is no more intro screen. You will get free updates for the lifetime of HAMlib, meaning a new registered version will be shipped to the email adress you registered with every time HAMlib is updated. The license you are buying is only for one single machine, and must not be used on more than one computer at a time. If your registered binary is used on more than one computer at the same time (and I get to notice this), your license will be terminated. This version does NOT come with the HAMlib source code.
