microHAM micro KEYER 2R Manual page 40

Router provides two modes to select the audio configuration, Fixed and automatic - Follow radio mode.
TIP: If Router can read frequency and mode from your radio (Ports tab | Set) use
mode. It will provide automatic selection of the appropriate audio configuration.
When Router is unable to read the operating mode from your radio (radio does not have computer control
port or does not report usable mode information), chose Fixed audio switching. There are several
optimized settings 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/FSK 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 button (foot switch) mode and allows playback of voice
messages from the computer. With this settings it is not possible to record voice messages in
application software.
–
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, allows
playback or recording of voice messages, and allows interrupting playback of a recorded message
by pressing the microphone PTT or foot switch. This setting is recommended for most VOICE use.
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 Orion or Orion II). Do not use with other software or radios.
SSTV (ACA) – Special setting for SSTV mode. Microphone is normally connected to the radio microphone
jack and allows VOX or foot switch VOICE operation. When an image is being sent from computer
sound card, the station mic is muted and drive applied to the transceiver mic input (Yaesu).
SSTV (ABA) – Special setting for SSTV mode. Microphone is normally connected to the radio microphone
jack and allows VOX or foot switch VOICE operation. When an image is being sent from computer
sound card output, drive is connected to the transceiver rear audio input (Kenwood, Ten-Tec,
Icom).
FSK, DIGITAL (BBB) – The station microphone is disconnected and the computer generated audio is
applied to the radio's rear panel audio input. This setting is recommended for all digital modes
operation regardless of keying type (FSK or AFSK).
DIGITAL (CCC) – The station microphone is disconnected and the computer generated audio is transfered
to the radio front panel mic jack. This setting is recommended ONLY for radios which do not have
rear panel audio input for digital modes like K2.
