microKEYER II Rear View
Note:  microKEYER II™ is a hardware product - it "fully supports" a radio when microHAM releases a cable set designed to interface microKEYER II 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.
