   •

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.

   •

Ultra low noise: 
- The sound circuits are designed with special attention to low noise 
- The receive noise floor in microKEYER II is lower than any value priced 
  
sound card or similar amateur product. 
Dynamic range rivals that of professional products.
- Special circuit design maintains full dynamic range and low noise floor   
     with all radios - both high level and low level outputs.

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.
