Greatly simplified The QCX circuit is simplified (i.e. 50% fewer components to install, 50% fewer components to install, no complicated transformer windings, no alignment procedures required), and is more versatile.Package Contents:1 x Transceiver1 x Handheld Microphone1 x Audio cable1 x For Morse key
