USB micro KEYER
 
Click here to read the review in the September 2005

QST

 
microKEYER™ is a powerful All-In-One multi-mode USB interface for CW, SSB, AM, FM, and digital modes (RTTY, PSK31, SSTV, APRS, PACKET, EchoLink and many others).
 
Using a single USB port and a sound card, microKEYER can interface with any Windows-based logging or control program to run any FSK, CW , AFSK, SSB, AM, or FM mode.
 
microKEYER also includes a rig control interface (CAT/CI-V) with interfaces for all supported radios, a powerful CW memory keyer, and a buffer for keying a Power Amplifier.
 
Package contains:   microKEYER™,  CDROM with drivers and control software, USB A-B cable 2m (6.5ft) long, three sound card cables 1.5m (5ft) long, and one radio cable (specify your radio). 
 
Discontinued
 
Note: an external power supply is required only with Kenwood, Elecraft K2 and Yaesu FT-847 transceivers.  With all other transceivers supported by microKEYER, power is obtained from the transceiver's auxiliary 13.5 volt output.   
 

 
Features and functions:

Note: microKEYER™ 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.  Their presence or absence in microHAM USB Device Router does not mean that a specific transceiver is, or is not, supported.
