4.1 RECEPTION (I)
NOTE:
Set the MIC and CAR controls to minimum to prevent
accidental transmission before tune-up is completed. The
TS-830S must be operated into a 50 ohm antenna or
dummy load with an SWR less than 2:1. Random length
wire antennas or light-bulb dummy loads cannot be used.
Conventional half-wave dipoles and beam antennas should
only be used at or near their resonant frequency. Exceeding
an SWR of 2:1 can damage the output stage of the
transceiver.
Adjust DRIVE control
for maximum deflection

(1) Basic Procedures for Receive Operation
The TS-830S has many advanced features such as VBT, IF
SHIFT, NOTCH, etc. to assure enhanced receive operation.
For the use of these specialized controls and switches, refer
to Section 4.2 "Reception (II)".
14
With a suitable antenna and microphone or key connected
to the transceiver, set the controls as described in Fig. 4-1.
Turn the POWER switch ON. The meter, dial scale, and VFO
indicator will light, indicating the transceiver is operating.
Advance the AF GAIN control clockwise until some receiver
noise is heard in the speaker. Turn the main tuning dial
within the frequency range of the Amateur band chosen until
a signal is heard. Tune the signal for clearest reception, and
then adjust the DRIVE control for maximum S-meter
deflection. (Fig. 4-2).
(2) WWYV Reception
Set the band switch to "10"
control to 10.0 MHz.
and turn the main tuning
4.2 RECEPTION (II)
This section covers operation of controls and switches to
provide maximum performance from the TS-830S.
(1) RF ATT SWITCH
The input to the receive RF amplifier is attenuated
approximately 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
reception when a strong adjacent signal may blank the
receiver or "Pump" the noise blankes.
