Transceiver Settings - Kenwood TS-990S Setting Manual

4.3. Transceiver Settings

Perform the required settings to implement KNS operations using transceivers.
● Set the transmitting audio input path settings
With KNS operations, normally transmitted audio is input from an ACC2
connector. Input is also possible using USB audio functions from a USB
connector, but as the delays are great, this is not recommended.
On the Modulation Source screen of the TS-990S, set "ACC2" to ON, to be
transmitted when "DATA SEND (PF)" is operated, to transmit audio input from
the ACC2 connector. (Refer to "SELECTING THE AUDIO LINE FOR
TRANSMISSION" in the instruction manual.)
Modulation Source can be configured for each DATA mode (DATA Mode Off,
DATA 1～3) that is currently selected.
Reference:
Set "USB audio" to ON, to be transmitted when "DATA SEND (PF)" is
operated, to transmit USB audio signals input to the USB connector.
Set a playback device and recording device to the device connected to the
TS-990S as a default using the Windows sound settings of the host station.
● Data VOX settings
With the TS-990S, VOX functions can be implemented using either audio
input to the ACC2 connector or USB audio signals input to the USB connector,
but to prevent unintentional transmission during KNS operations, turn OFF
the function on the Modulation Source screen.
Caution:
When this function is ON, be aware that all sounds created by the PC other

than the intended audio transmissions are also transmitted.
When using this function for the first time, we recommend connecting a

dummy load to the TS-990S to perform checks and adjustments.
