tion with the H SW switch turned to OFF 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 the clearest possible reception. and then
adjust the DRIVE control for maximum deflection of the S--
meter.
4.1 PRELIMINARY PROCEDURE
Set the MIC and CAR controls to zero and the MODE switch
to LSB. USB. or CW to prevent accidental transmit con-
ditions before tuning. The TS-820S must be operated into a
50 ~ 75 ohm antenna or dummy load with an SWR less
than 2 : 1. Random length wire antennas or light-bulb dum-
my 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 components in the output stage of the
transceiver,
The RF GAIN control varies the AGC feedback voltage which
effects the S-meter reading. With the RF GAIN control fully
clockwise. the S-meter gives a proper signal strength rea-
ding Tuning the control counter-clockwise reduces the RF
GAIN. reducing signal strength and band noise
Be sure to complete all of the required cabling. as described
in Section 2.3 " 2.8.
With a suitable antenna and microphone (or key) connected
to the transceiver. set the T5-8205 switches to positions des-
cribed in Table 1
4.3 READING THE OPERATING
FREQUENCY
4.2 RECEIVER TUNING
Refer to Table 1 for the initial switch settings of the T5-8205
for receiving. and then continue with the described proce-
dure.
The frequency dial of T5-8205 indicates accurate carrier
positions regardless of operating modes because of the use
of a special circuit system. thus the transmit and receive fre-
quency can be directly read on the dial. except for CW recep.
tion in which case the frequency on the dial is lower by the
beat frequency than the receive frequency
When the digital display is used.
If there is any difference between the frequencies on the dial
