microKeyer 2R, microkeyer 2R+

And once again - all in one controller, but now for two radios! The ideal device for all demanding radio amateurs who have more than one radio on their desk. And also highly suited for Single-Op/2 Radio (SO2R) operations in a contest.

MK2R+™ is a 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.

Package contains: MK2R™ or MK2R+™, USB cable, LPT cable, two (2) stereo audio cables, headphone cable ending with two (2) 6.3 mm (1/4") plugs, two (2) 3.5 mm (1/8") plugs, one (1) coaxial 2.1mm/5.5 mm power plug, two (2) RCA to RCA cables, and CD-ROM containing the microHAM USB Device Router program and documentation. We offer an optional 10 keys keypad MK-KEYPAD, see below.

  • Notes
  • MK2R and MK2R+ are hardware products - its level of functionality is determined by the features offered by the application software and transceivers with which it is used. MK2R and MK2R+ "fully supports" a radio when microHAM releases a cable set designed to interface MK2R to the specific input/output requirements of a supported transceiver. Due to differences in capabilities among transceivers, the support software (microHAM USB Device Router) and/or MK2R may not implement microphone muting, FSK and/or frequency decoding for all supported radios.
  • You will need at least one radio specific cable-set, or two cable sets if you plan to use two radios. For schematics of the cables please see below at the 'microKEYER', the cables are the same.
  • A computer with at least 800MHz processor clock is recommended for use with the micro-Keyer 2R/2R+.

Note: microHAM USB Device Router and microHAM Device Configurator are compatible with all 32bit and 64bit versions of Windows 7, Windows 8, Vista, XP, 2000 and 2003.
