**please rememeber to select the right lead for your radio from the drop down list above. Cable list at bottom of this page.

micro KEYER II™ is the most powerful single radio All-In-One USB interface and the only USB interface to fully support voice operation including microphone switching.With an single USB port, microKEYER II™ works with any Windows-based logging or control program for CW, voice, FSK and digital (RTTY, PSK31, SSTV, OLIVIA, MFSK, WSJT, etc.) operation. micro KEYER II™ includes a radio control interface that supports all standards (RS-232, CI-V, Kenwood and Yaesu TTL), a powerful CW memory keyer using K1EL's WinKey, a Digital Voice Keyer, two channel audio for transceivers with dual receivers, automatic microphone selection, and a buffer/sequencer for amplifier or LNA control.

No serial or parallel port required:
- just one USB cable between your computer and microKEYER II

Complete "Computer Radio" electrical isolation
- transformer isolation between sound circuits and radio
- optical isolation between USB port and of ALL digital signals: Radio Control, CW, PTT, FSK, PA PTT, & LNA PTT

Standard Sound Device - no custom drivers: 
   The microHAM CODEC is an industry standard device recognized by 
   Windows, Apple OS 10 and LINUX. There are no custom device drivers 
   to install and no compatibility problems with your favorite applications.

Note: microKEYER II is a hardware product 
it "fully supports" a radio when microHAM releases a cable set designed to interface microKEYER to the specific input/output requirements of a supported transceiver.  Due to differences in features and control protocols among transceivers, the support software (microHAM USB Device Router) may not implement decoding of operating mode and/or frequency, automatic selection of mode, frequency/mode dependent configurations, and/or FSK for all supported radios. Automatic selection of frequency/mode dependent configurations is a user interface enhancement. The ability of microHAM USB Device Router to provide automatic selection of operating configuration does not mean that a specific transceiver is, or is not, supported.
