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"0".
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.

4.1.4. 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.
