2. The transceiver is switched to transmit by PTT on virtual serial port or by WinKey generated PTT.
This setting is displayed in the MIDDLE picture and indicated by the second letter in settings scheme (ACA).
The current operating state is indicated by a large black frame around the switching picture.
A: Computer audio is disconnected from the radio
and the station microphone is connected
directly to the transceiver front panel
microphone jack. This setting is for those who
prefer VOX operation in SSB.
B: Computer generated audio is routed to the
transceiver rear panel and the station
microphone is muted. This is the preferred
setting for digital mode operation (AFSK, PSK,
etc.) when the computer generates a PTT
keying signal on a virtual port.
C: The station microphone is connected to the
sound card mic input and audio from the
sound card is routed to the transceiver
microphone input. This setting is useful for
SSB message playback (DVK). This
configuration is useful for voice keyer operation (DVK) and is the preferred setting with N1MM Logger,
Win-Test, or WriteLog.
3. Transceiver is switched to transmit by footswitch or hand microphone PTT button.
This setting is displayed in the BOTTOM picture and indicated by the third letter in settings scheme (ACA).
The current operating state is indicated by a large black frame around the switching picture.
A: Computer generated audio is disconnected
from the radio and the station microphone is
connected directly to the transceiver front
panel microphone jack. This setting is for SSB
when the microphone should be connected
directly to the transceiver.
B: Computer generated audio is routed to the
transceiver rear panel and the station
microphone is muted. This is the preferred
setting for digital mode operation (AFSK, PSK,
etc.) when the computer generates a PTT
keying signal on a COM port.
C: The station microphone is connected to the
sound card mic input and audio from the
sound card is routed to the transceiver
microphone input. This setting is useful for
SSB message playback (DVK). This configuration is useful for voice keyer operation (DVK) and is the
preferred setting with N1MM Logger, Win-Test, or WriteLog.
