This is a prerlease segments for bastard Sons of Dial-Up – www.BSoDtv.org This is a build of the Tiny TNCx Kit, which hooks to a ham radio (or your FRS Radio) that lets you operate digital modes. A Terminal Mode Controller (TNC) is pretty much an old school modem. It turns binary bits of data from a terminal (a computer or PDA) into sound which can then be transmitted over radio waves.
