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
adjustment is not required.
