Delaying The Audio Signal; Tx Monitor; Adjusting The Tx Monitor Level - Kenwood TS-990S Instruction Manual

DELAYING THE AUDIO SIGNAL

While using VOX, there is a time lag between the time
you start talking on the microphone and the time the
transceiver begins transmitting. As a result, speech
clipping may occur. To prevent this as much as possible,
set a VOX voice delay time (a time lag) to transmit the
audio signal after the transceiver is placed into a transmit
state.
1 Select Group No. 6, "TX/RX Filters & Misc", from the
Menu screen.
2 Access Menu 09, "VOX Voice Delay (Microphone)".
If anything other than Microphone is configured for the audio
source for transmission, you must access to Menu 10, "VOX
Voice Delay (Except Microphone)".
3 Press [SELECT] (F4) to allow editing of the parameter
box.
4 Press [ ] (F2) or [
VOX Voice Delay Time.
• Select "Off", "Short", "Medium", or "Long".
• The default is "Medium".
5 Press [ ] (F1).
6 Press [MENU] to exit.

TX MONITOR

You can monitor the audio during transmission. This
function is convenient when you check the effectiveness
of the speech processor or TX DSP equalizer. In FSK and
PSK modes, you can monitor FSK and PSK signals to be
transmitted from the transceiver.
[MONI] [MONITOR]
1 Press [MONI] to enable or disable the transmit monitor.
The "MONI" LED lights green while the TX monitor is active.

ADJUSTING THE TX MONITOR LEVEL

With this transceiver, you can adjust the monitor level of
the transmission audio.
1 Rotate the MONITOR control to adjust the volume level
of the TX Monitor.
Note:
◆ In SSB, AM and FM modes, an acoustic feedback may result while
the speaker is in use. Use a set of headphones, instead.
◆ The transmission of the CW message cannot be monitored using
the TX monitor. You can monitor a CW transmission using CW
sidetone.
◆ In FM, FSK and BPSK mode, the audio in the TX monitor differs
from the audio signal actually transmitted.
◆ This transceiver has an RF monitor that demodulates the
modulated waves while in SSB and AM modes and an AF monitor
while in FM, FSK and PSK modes. The audio in the AF monitor
differs from the audio actually transmitted.
