DIGI KEYER II™ is a powerful All-In-One USB interface for amateur radio digital mode operation including RTTY, PSK31, MFSK, Olivia, WSJT, APRS, PACKET, and many others which builds on the proven DIGI KEYER

DIGI KEYER II™ includes a rig control interface for all supported radios (Elecraft, Icom, JRC, Kenwood, Ten-Tec, and Yaesu), an internal Stereo sound chip using standard Windows Sound drivers, K1EL WinKey CW Keyer, and independent PTT outputs for both LNA and Power Amplifier control. 

Package contains:  DIGI KEYER II™ CDROM with drivers, control software and manual, USB A-B cable 2m (6.5ft) long, and one radio cable.

 

Features and functions:

 
DigiKeyer II™ block diagram
   • No serial or parallel port required - just one USB port
- Fully integrated: Sound Radio Control, true FSK and PTT 
- Computer sound card is not used 
   • 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 USB Sound Device 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 
- DigiKeyer II's noise floor is lower than any value priced soundcard 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.
 
   • Compatible with most standard Windows software 
- special microHAM USB Device Router creates as many virtual COM ports as needed to support your favorite programs
- customizable presets allow instantly changing configuration
    when switching programs
   • Integrated control port for all radios: CI-V, FIF-232, IF-232, RS-232
- fully supports Elecraft, Icom, JRC, Kenwood, Ten-Tec, and Yaesu radios
   • Dual Channel Receive:
- Supports simultaneous, independent receive with dual receiver radios 
- independent, front panel level controls for each receiver
   • Front Panel Level Adjustments: 
- Pots for Transmit level, Main Receiver level and Aux receiver level 
- no need to fumble with Windows Mixer to control levels 
   • Integrated K1EL WinKey™ chip with extended capabilities:
- front panel speed knob 
- nine (9) user programmable memories 
- internal paddle buffer for improved reliability. 
- PS/2 keyboard support for direct CW generation.
- PS/2 keyboard/keypad CW; works without a computer connection
- auto PTT 
- all parameters are stored in EEPROM and reloaded on power up
   • Hardware generated FSK 
- capable of sending 5/6/7/8 bits and 1/1.5/2 stop bits
- PS/2 keyboard support for direct FSK transmission without a computer
- PS/2 numeric keypad support for instant FSK message playback
- PS/2 keyboard works without a computer connection
   • Sound card Right channel audio detector and FSK/CW driver 
- capable of sending 5/6/7/8 bits and 1/1.5/2 stop bits
- Provides a "hard keyed" CW output for software that generates
   only audio (sidetone) CW
   • Utilizes your radio's rear panel connections (where available)
- all audio input and output is via rear panel connections 
- leaves your mic connection free for the microphone  
- PTT controls mute the microphone on supported radios
   • Independent keying buffer for Power Amplifier
- extended range solid state output for modern PA 
- relay isolated output for vintage PA with negative voltage T/R relay
   • Independent keying buffer for Low Noise Amplifier switching 
- extended range solid state or relay isolated outputs
- Bypass LNA before activating both PTT circuits for EME or scatter
   • Footswitch input with programmable functions 
- programmable PTT activation delay in 1ms steps
- selectable muting of CW and/or FSK when footswitch is closed
   • Squelch input for signaling to computer
- two inputs: one active low, second active high
- ideal for Echolink and remote interfacing applications
   • No external power adapter (where the radio provides auxiliary power) 
- No noisy DC to DC converters
- USB and Sound chip are powered from the computer USB port
- Controller is powered from transceiver or transceiver power supply
- Will not overload your USB port
   • Strong RFI immunity
- integrated chokes and filters for best RFI immunity
- advanced shielding and circuit design to suppress RFI generation
   • Input/Output connectors
- Computer: USB,  Radio: DB15
- Remote - MiniDIN6,  Amplifier keying - RCA, LNA keying - RCA
   • LEDs for CW/FSK and PTT and Squelch
   • Metal/Aluminum case, powder coated and silk screened
   • Free firmware/software upgrades via internet
 
 
Note: DIGI KEYER II™ is a hardware product - it "fully supports" a radio when microHAM releases a cable set designed to interface DK II 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 DigiKeyer II may not implement FSK and/or radio specific functions for all supported radios.
