Fig. 4-1 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. For SSB
operation the MODE switch should be set to comply with
common operating practice: that is. it should be set to LSE
for the 3.5 and 7 MHz bands and to USB for the bands
above 14 MHz
Ascertain that the TS-120S(V) is ready for operation, then
turn, the POWER switch ON. The meter, d i a l scale and
digital display will lluminate. indicating the transceiver isin
operation. The transceiver is fully solid-state, allowing
reception as soon as the POWER switch is turned ON.
'Advance the AF GAIN contro! clockwise until some receiver
noise is heard from the speaker. Turn the main tuning knob
so the desired signal can be heard clearly
While turning the main tuning knob. the frequency (MHz
digits) reading on the digital display wil change at the edge
of each band (for example, from (28.999.9} ro {23.000.0)
MHz). When tuning above or below a band edge. the 1 MHz
and 10 MHz digits are blanked. as shown below.

4.1.2. NB SWITCH
The TS-120S{V) has a sophisticated noise blanker designed
to reduce ignition-type pulse noise. The noise blanker is pi
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 the signal
is absent

4.1.1, WWV RECEPTION
To receive WWV at 15 MHz, set the BAND switch to
JJY/WWV and turn the main tuning knob until the subdial
reads "500". The digital display indicates "000.0" instead
of 15.0000.
