microHAM MK2R Manual page 42

NOTE: Use "Select by frequency" only if your radio does not have a dedicated mode (PKT, DIG, DATA or
USB-D/LSB-D etc.) for audio based digital modes like PSK31, MFSK, OLIVIA, FSK-RTTY etc.
and you must use USB/LSB/FM for digital operation.
Use VOICE settings: VOICE settings will be used when LSB, USB, AM or FM are selected regardless of
operating frequency. This should be used with most Yaesu transceivers, Icom transceivers that support
USB-D and LSB-D and the K3.
Use DIGITAL settings: DIGITAL settings
will be used when LSB, USB, AM or
FM are selected regardless of
operating frequency.
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.).
There are several audio switching configurations for each operating mode.
CW (AAA) – The audio configuration is not important for CW operation. This choice has been included to
maintain consistency with T/R keying (configured on the PTT tab) where it is important. CW (AAA)
assures quiet audio switching and minimizes relay clicking.
VOICE (ACmA) – The station microphone is connected to the radio mic jack. When the computer generates
PTT on the virtual port PTT channel, the sound card output is switched to radio mic jack. This setting
works with VOX or PTT (foot switch) mode, allows DVK playback, supports input switching for SSTV,
and allows interrupting playback of a recorded message by pressing the microphone PTT or foot switch.
When a DVK message or SSTV image is being transmitted, the station mic is muted and the computer
audio is applied to the transceiver microphone input. With this setting, DVK messages must be recorded
in the "on air" mode. This setting is recommended for general VOICE use.
VOICE (CmCmA) – The station microphone is connected to the sound card mic input except when the foot
switch or microphone PTT is pressed. When the microphone PTT or foot switch is pressed, the
microphone is connected to the radio. This setting allows use of VOX or manual PTT, off air recording of
voice messages, and allows interrupting playback of a recorded message by pressing the microphone
PTT or foot switch.
VOICE (CmCmCm) – The station microphone is always connected to the sound card mic input. This is the same
as above but when the foot switch or hand mic PTT is pressed, the microphone remains connected to
the sound card.
VOICE (CmBA) – Special setting for radios which use the rear panel audio input for DVK input during voice
operation (N1MM Logger with Ten-Tec Orion or Orion II). Do not use with other loggers or radios.
VOICE (ABA) – Special setting for SSTV mode. The microphone is connected to the radio microphone jack and
allows VOX or foot switch VOICE operation. When an image is being transmitted, the sound card audio
is connected to the transceiver rear audio input (Kenwood, Ten-Tec, and Icom transceivers) and the mic
is disconnected. This setting is not recommended for DVK operation with Icom transceivers.
