Control and Switch Settings
4.1
RECEPTION
First connect the antenna, microphone and key.
Then, set
the controls and switches referring to Fig. 4-1.
Ascertain that the TS-130SE
is ready for operation, then
turn the POWER
switch
ON.
The
meter,
dial scale and
digital display will illuminate, indicating the transceiver is in
operation.
The
transceiver
is fully solid-state,
allowing
reception as soon as the POWER
switch is turned ON.
Advance the AF GAIN control clockwise until some receiver
noise is heard from the speaker.
Turn the main tuning con-
trol so the desired signal can be heard clearly.
4.1.1.
WWV
RECEPTION
To receive WWV
at 10 MHz, set the BAND switch to "10"
and turn the main tuning control until the subdial reads''O".
4.1.2 RF ATT switch
The
input to the receive
RF amplifier is attenuated
ap-
proximately 20 dB, providing distortion-free reception.
This
feature may be used in cases of receiver overload, caused
either by a strong local signal, or during weak signal recep-
tion when a strong adjacent signal may blank the receiver.
4.1.2.
NB SWITCH
The TS-130SE
has a sophisticated noise blanker designed
to reduce ignition-type pulse noise. The noise blanker is par-
ticularly important for mobile operation.
When
necessary,
activate the noise-blanker by depressing the NB switch ON.
4.1.3.
RF GAIN
CONTROL.
(Fig. 4-2)
For normal
operation, this control should be turned fully
clockwise
for maximum
sensitivity.
Receive sensitivity is
reduced by turning the control counterclockwise.
Adjust
the RF GAIN
so the S-meter
does
not show
ex-
cessive
deflection.
This minimizes
noise during reception
and allows the S-meter to indicates signal peak (or a little
below that point).
Noise is markedly reduced when signal is
absent.

RIT CONTROL
By using the RIT (Receiver Incremental Tuning) control, the
receive frequency can be shifted by about + 1.5 kHz without
changing the transmit frequency.
If the frequency of the station you are working changes, your
receive frequency can be reset by turning the RIT switch ON
and
adjusting
the
RIT
control.
Adjusting
the
control
clockwise
increases
the frequency.
The
RIT shift can
be
checked by the digital display.
When first calling another
station, the RIT should be OFF, otherwise your transmit and
receive frequency
will not coincide
