3.1 FRONT PANEL CONTROLS
CD METER
@ VFO INDICATOR
The VFO indicator is a light emitting diode which illuminates
whenever the TS-820S's internal VFO is controlling the trans-
ceiver's operation. The indicator is not lighted during fixed
channel, or remote VFO. operation
The meter monitors six different functions. depending on
the position of the METER switch. In receive the meter is
automatically an 5-meter The 5-meter shows received si-
gnal strength on a scale of 0 to 40 db over 59 In transmit
the meter function depends on the position of the METER
switch. as described below
@ RIT INDICATOR
This light emitting diode is illuminated when the RIT circuit
is turned on. showing that the transmit and receive frequen-
cies may be different ~ METER SWITCH
The position of the METER switch determines the function
of the meter The switch selects one of the following func-
tions (see Section 4 for nominal meter readings):
<1)
SUB-DIAL
The sub-dial is turned with the main tuning knob to select
the operating frequency of the transceiver It is calibrated at
50 kHz intervals from 0 ~ 500 kHz.
ALC
(Automatic Level Control) -In thIs position the
meter monitors the ALC voltage of the internal
ALC circuit (or the AlC voltage feedback from a
linear amplifier operated in conjunctIon with the
TS-820S). For SSB operation the ALC reading for
voice peaks shquld be within the indicated ALC
range of the meter. The ALC voltage adjustment
is made with the MIC control for SSB and with
the CAR control for CWo
@ DIAL SCALE
The unique mono-scale permits direct reading of frequencies
over the range of 0 to 500 kHz graduated at 1 kHz irller-
vats. Operating frequency can be obtained by adding the
frequency read on the dial to the frequency (MHz) indIcated
on the BAND switch.
(Plate Current) -In this position the meter moni-
tors the plate current of the final tubes. The me-
ter scale is calibrated from 0 to 350 ma.
IP
(ii DIAL CALIBRATE KNOB
This knob is used to calibrate the reading on the dial scale.
It should not be used for turlll\g purposes
(Output Power) -In this position the meter mo-
nitors the relative output power of the transcei-
ver. There is no meter scale for this Rosition.
Normally the reading should be adjusted with the
RF VOLT control for a 2/3 scale meter reading.
RF:
@ MAIN TUNIG KNOB
This knob turns the VFO and dial scale to select the fre-
quency to be added to the bslld frequency to establish the
transceiver's operating frequency
This indicates the state of compression when the
speech processor is operated.
caMP:
@ STAND-BY SWITCH
This two position lever switch selects one of the following
functions
(High Voltage) -In this position the meter moni-
tors the high voltage from the power supply. The
meter scale is calibrated from 0 to 10. indicating
0 to 1000 volts.
HV
The transceiver is receiving unless the micro-
phone PTT switch is switched to transmit, or the
VOX circuit is activated.
REC:
SEND
The TS-820S is locked into the transmit mode in
this switch position.
@ ATT INDICATDR
This indicator uses a light emitting diode. It is illuminated
when the RF A TT switch is turned to ON
@
FIX (FIXED CHANNEL OPERATION)
INDICATOR
~
The FIX indicator is a lightemltting diode which illuminates
whenever the TS-820S's internal fixed frequency oscillator is
controlling the transceiver's operation
