MK2R™ and MK2R+™ are most powerful All-In-One multi-mode two radios USB controller for CW, SSB, AM, FM, and digital modes (RTTY, PSK31, SSTV and many others) designed for the serious contest operator or DXer with two transceivers. microKEYER 2R includes rig control interfaces for two supported radios (Elecraft, Icom, JRC, Kenwood, Ten-Tec, and Yaesu), independent PTT outputs for both LNA and Power Amplifier control, an improved, second generation WinKey CW Keyer, receive and transmit audio switching.

microKEYER 2R Plus also includes a unique, dual codec sound system for audio processing.
