fixed channel crystals are installed in the transcei.
verI.
the RIT circuit is ON By turning the RIT knob. the receive
frequency of VFO can be changed by :t3 kHz and the fre-
quency of fixed channel by :t 150 Hz without changing the
transmit frequency.
@ H. SW (HEATER) SWITCH
This switch turns the heater circuits of the three transmitting
tubes on and off. The heaters would normally be turned to
OFF to reduce power consumption in mobile or portable re-
ceiving.
@ BAND SWITCH
This 11-position switch selects all the necessary circuits to
tune the transceiver to the desired 500 kHz band.
~~ POWER SWITCH
The POWER switch turns all the power on and off in
TS-8205.
@ FUNCTION SWITCH, ,
This 7 -position rotary switch selects one of the following
transceive functions.
This position allows calibration of the 1"5-8205'5
internal VFO to one of the transceiver's fixed fre-
quency channels (if an optional fixed channel cry-
stal is installed), With the switch in this position a
signal is generated at the selected fixed channel
frequency and the main tuning knob can be tuned
to zero beat the calibrating signal,

FIX:
@ RIT KNOB
This knob is used to change receive frequency when the AIT
circuit is in operation Set the center position (0) of the
AIT knob to the AIT -OFF.
@ IF SHIFT KNOB
By using this knob during reception. the center frequency of
the IF crystal filter can be shifted by :t 17 kHz. facilitating
the adjustment of the tonal quality of receive signal or elimi-
nating radio interference from nearby frequencies. For nor-
mal operation. this knob should be set to the center position
(click is heard).
This position alloWs calibration of the VFO-820
(remote VFO) to the transceiver's operating fre-
quency. With the switch in this position. the
transceiver generates a calibrating signal and the
VFO-820 can be tuned to zero-beat the calibra-
ting signal.

RMT
(:j~ MIC GAIN KNOB
This knob is used for adjustment of the gain of MIC amplifier
during sse operation. Adjust so that the meter pointer does
not deflect beyond the ALC lone.
With the switch in this position. the transceiver's
calibrator circuit generates a marker signal at
every 25 kHz for normal calibration of the internal
VFO.
CAL-
25 kHz:
The switch is kept in this position for normal
transceive operation.
VFO:
@ CAR (CARRIER) LEVEL KNOB
Used to adjust carrier level during CW operation. Adjust so
that the meter does not deflect beyond the ALC lond.
With the switch in this position. the TS.820S's in-
ternal VFO controls the receive function and the
internal fixed channel oscillator controls the trans-
mit function (if fixed channel crystals are installed
in the oscillator).
VFO.R
@ AF GAIN KNOB
This knob adjusts the gain of the receiving audio amplifier
The audio volume of the received signal increases as the
control is turned clockwise.
With the switch in this position, the TS-820S's in-
ternal VFO controls the transmit function and the
built-in fixed channel oscillator controls the re-
ceive function (if fixed channel crystals are instal-
led in the oscillator) The VFO.R and FIX.R allow
cross-channel operation without an external VFO.
FIXR:
@ RF GAIN KNOB
This control adjusts the gain of the receiver sections RF am-
plifier. Turn the knob fully clockwise for maximum gain and
for a correct S-meter reading Turn the control counter--
clockwise to reduce the gain.
@ FIX CH (FIXED CHANNEL) SELECT SWITCH
This four-position rotary switch selects between four diffe-
rent fixed frequency channels which can be installed Inside
With the switch in this position. the IS-820S's
fixed channel oscillator controls the transmit and
receive function of the transceiver (if accessory
