The VOICE and FSK/DIGITAL settings can independently specify whether audio generated by microHAM
CODEC should be sent to the microphone jack or line input based on the operating mode.
VOICE settings:
Microphone jack, DVK control (default): The audio from microHAM CODEC is connected to the
transceiver's microphone jack when transmitting under DVK control - including while recording
DVK messages with "On Air recording" selected.
Microphone jack, logger and DVK control: The audio from microHAM CODEC is connected to the
transceiver's microphone jack when transmitting under DVK control or when commanded by user
software (e.g., a logging program).
Line input (rear): The audio from microHAM CODEC is connected to the transceiver's rear panel (line)
input.
Remote microphone The audio from microHAM CODEC is connected to radio microphone jack all the
time and does not switch to the local microphone. This selection is useful for use with computer
based transmit audio DSP processing (for example, 3
rd
party audio equalizer software) or for use
with remote operation of MKII.
FSK/DIGITAL settings:
Line input (rear): Audio from microHAM CODEC is connected to the radio rear panel (line) input all the
time. This is the default setting for FSK/Digital operation.
Microphone jack. Audio output of microHAM CODEC is connected to radio microphone jack all the time.
NOTE: The graphic is “live” and shows the current audio routing. The grey lines show the selected audio
path and the red lines show those paths currently transferring audio. The graphic is an excellent
tool for troubleshooting the audio configuration.
Sound Card: is only visible with
Vista and Windows 7. It
shows the Name, Mixer
ID, Wave In ID and Wave
Out ID for each
input/output in the
computer. The ID
numbers are necessary to
properly configure of
some applications (for
example: WSJT, MMVARI
etc.).
Sound card overrides microphone: When checked, audio from the sound card can override signal from
microphone even if footswitch is depressed. "Restore serial PTT and audio routing" must be selected on
the PTT tab to avoid disabling audio from the sound card when the footswitch is released.
