2. Transmit by computer generated PTT or WinKey PTT.
This setting is displayed in the MIDDLE picture and indicated by the second letter of the settings
(ACmA). 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 microphone jack. This
setting is for VOX operation.
B: Computer generated audio is routed to the
transceiver accessory input and the station
microphone is muted. This is the preferred
setting for digital mode operation (AFSK, PSK,
etc.) when the computer generates a PTT signal
on a virtual port.
C: The station microphone is connected to the
sound card microphone input and audio output
from the computer is connected to the radio's
microphone input. This setting is similar to "A"
but microphone signal goes through the sound
card. This configuration is useful for voice keyer operation (DVK) and is the preferred setting with N1MM
Logger, Win-Test, or WriteLog.
3. Transmit by foot switch or hand mic PTT.
This setting is displayed in the BOTTOM picture and indicated by the third letter of the settings (ACmA).
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 microphone is connected directly to
the transceiver microphone jack. This setting
allows the operator to interrupt a DVK message.
B: Computer generated audio is routed to the
transceiver accessory input and the station
microphone is muted. This is the preferred
setting for digital mode operation (AFSK, PSK,
etc.) when the computer generates a PTT signal
on a virtual port.
C: The station microphone is connected to the
sound card microphone input and audio output
from the computer is connected to the radio's
microphone input. This setting is similar to "A"
but microphone signal first goes trough the
sound card.
Even though all possible combinations can be accessed by clicking on the "Allow custom settings" box, not
every combination is practical. Router preselects the most useful settings for each mode group.
