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.
