    The software interface is provided as Virtual Serial Ports. In order to configure and use microKEYER II with Windows compatible application programs, you must be running Router and have turned on microKEYER II. Router is then configured as required by the application (logging, control or digital mode) software.
  • Page 12: Creating And Using Virtual Serial Ports

    Router provides a set of virtual serial ports which allow Windows applications (logging and digital software) to work with microKEYER II just as they would work with "real" (hardware) serial ports. In order to use these virtual Ports, you must first create the ports and then assign a port to each function you wish to use (radio control, PTT, CW, FSK, etc.).

  • Page 19: Nd Cat

    CAT is not reliable because RFI can prevent the radio from switching back to receive. In addition, microKEYER II cannot control an amplifier when the application uses PTT by CAT since it has no way to sense that the the application has placed the transceiver into transmit. There is a dedicated T/R switching channel for this purpose called PTT.
  • Page 20 © 2008 All rights reserved Disable router queries – When this box checked, Router will not poll the radio for frequency and mode when that information is not available from the communication between the application and radio. NOTE: "Disable router queries" disables Router polling only when the port has been opened by an application program.
  • Page 21: Fsk & 2

    © 2008 All rights reserved NOTE: Although Router has been tested extensively using many different applications for the CAT and 2 ports, microHAM cannot guarantee proper operation with every possible combination of software. FSK & 2 FSK PORTS The FSK channels are used by application programs to send the FSK keying signal. FSK is used primarily for RTTY.

    © 2008 All rights reserved WinKey PORT WinKey is a unique external CW processor developed by Steve Elliot, K1EL. This CW processor supports paddle input like any other electronic keyer, offers many configuration options, and in addition converts ASCII data from the computer to Morse characters. This unique property assures perfectly timed CW output from the computer regardless of OS load.

    If a line ends in three dots (...) it means that the command or response has been broken across two USB packets. CONTROL PORT The Control Port allows an application program (logger) that implements the microHAM Control Protocol to make use of microKEYER II's CW, FSK and DVK message memories When an application opens the control port, Router reports port as open and displays settings used to configure COM port.
  • Page 26: Audio Switching Tab

    © 2008 All rights reserved AUDIO SWITCHING TAB microKEYER II uses an advanced, custom USB audio subsystem which allows Router to handle all of the audio routing. Microphone and receive audio are always connected to microHAM CODEC (the microKEYER II “sound card”).
  • Page 27 The black box will show the selected microphone. Transmit Monitor: microKEYER II includes a monitor ampflier that provides 2 watts to a user supplied speaker. Router will select the audio source to be monitored based on the operating mode. The monitor level can be set independently for each source/mode.
  • Page 28: Audio Mixer Tab

    If Stereo is not selected, the Audio Mixer tab will display a single set of controls and will mute the right channel. MicroKEYER II uses the left channel for all output but in some cases you may want to use the right channel for another purpose.

  • Page 30 Note, the display is active only if a sample rate is selected. microKEYER II shows one sliders for each input – Left for the Main RX and Right for the Sub RX. Keep the sliders at about 80% and use the RX Main and RX Sub pots on the front panel for adjustment.
  • Page 31: Ptt Tab

    ● PTT OUTPUTS microKEYER II has four PTT outputs: PTT1, PTT2, PAPTT and LNA PTT. PTT1 and PTT2 are brought out to the DB37 Radio connector. PAPTT and LNA PTT are RCA jacks for connecting to external devices. PTT1 is wired to the radio microphone jack and is generally used for VOICE modes.
  • Page 32 © 2008 All rights reserved MicroKEYER II can select the PTT output based on the mode, and optionally frequency, reported by the transceiver in response to polling by the application (logger) and/or Router. If Router is not able to read the operating mode from your radio (radio does not have computer control port or does not report usable mode information), you can select one of four fixed “no radio”...

    It is absolutely important to prevent ground currents from flowing to the common ground point by way of the signal cable. If you use a microHAM "keyer," a good test is to remove the DB15/DB37 connector and USB cable from the keyer and measure the resistance from the shell of the DB15/DB37 to the shell of the USB cable.
