4.3 VOX OPERATION
4.3.1. VOX SWITCH
VOX (voice operated transmit) is used to switch the TS-
130SE into transmit mode by your voice. Depress the
switch ON and speak into the microphone. The transceiver
automatically switches to transmit mode (the MIC control
should be adjusted in advance as explained in Item 4.2.2).
Both the send switch and the MIC P.T.T. switch are left in
the REC position.
4.3.2. VOX GAIN CONTROL
This adjusts the VOX circuit sensitivity. Speak into the
microphone at normal voice levels and adjust the control.
Clockwise increases sensitivity, allowing transmission with a
low voice level. Transceiver operating condition can be
checked by the sound from the speaker. When the speaker
is silent, the transceiver is in transmit mode.
Note that if the control is advanced too far, the VOX circuit is
"tripped" by ambient noise.
4.3.3. ANTI-VOX CONTROL
This prevents the VOX circuit from being "tripped" by sound
from the speaker.
Adjust the control so the VOX will not operate at the desired
speaker volume level.
4.3.4. VOX DELAY CONTROL
This control adjusts the transmit hold time of the VOX cir­
cuit. If the hold time is too short, the transceiver will return
to receive mode as soon as you stop talking into the
microphone. This can be eliminated by turning the control
clockwise. Adjust the control for comfortable operation at a
normal rate of speech.
4.4 SEMI-BREAK-IN OPERATION
The TS-130SE has a built-in side-tone oscillator to permit
semi-break-in operation, besides the normal CW operation.
During semi-break-in operation, the transceiver is placed in
transmit mode when the key is depressed, and returns to
receive mode when the key is released. The VOX circuit is
activated by the side-tone.
For semi-break-in operation, set the VOX switch ON and the
MODE switch to CW. Adjust the VOX GAIN to insure that
the transceiver is set in transmit mode whenever the key is
depressed. Also, adjust the VOX DELAY for desired hold-in.
ANTI VOX acljustment is not required.
4.5 OPERATION WITH A LINEAR
AMPLIFIER
The ACSY connector on the rear panel provides for inter­
connection with an amplifier. See the amplifier instruction
manual to determine whether the linear requires a normally
opened or normally closed (during receive) relay contact.
Connect the amplifier control line to either pin 5 (N.C.) or pin
4 (N O. during receive). Connect the Ground (Shield) of the
Control Line to Pin 2 and Pin 7. Connect amplifier ALC to
pin 6 of the ACSY connector. The TS-130SE output is quite
adequate to drive most amplifiers to full rated output.
4.6 FIXED CHANNEL OPERATION (Fig. 4-6)
The TS-130SE has a built-in crystal oscillator for fixed-
channel operation. This feature is most useful for commonly
used frequencies, nets, or any situation where crystal-
controlled operation is required.
