Operation W I T H A Linear Amplifier; Fixed Frequency Operation - Kenwood TS-820 Operating Manual

When interference is encountered. turn the iF SHlFT knob
and the interference can be eliminated. For more effective
CW operation. use the CW filter YG-88C (option) by refer-
ring to page 34.
OPERATION W l T H C W FILTER (OPTION)
Set the transceiver in the receive mode by setting the IF
S H l F T knob to the center posltion and the RIT switch to the
OFF position Adjust the main tuning knob for maximum de-
flection of the S meter. The pitch of the sound of the receive
signal will now be about 8 0 0 Hz. indicating that the zeroing
is completed.
Turn the RIT switch t o ON and adjust the RIT knob for your
desired p ~ t c h of the sound. Also. adjust the IF SHlFT knob
for maximum signal strength.
OPERATION W l T H D I G I T A L DISPLAY (OPTION)
The digital display indicates the frequency of carrier signal
(BFO signal) so that the frequency indicated is deviated from
the transmit frequency of the opposlte station by the receive
beat frequency during CW reception ( w i t h IF SHlFT knob set
to its center position. the frequency indicated becomes lo-
wer).
To z e r o ~ i n the frequencies with the optional digital display
DG-1, set the RIT switch to O N and turn the RIT knob while
manipulating the standby switch. in order to locate a point at
which the frequency indicated is not changed regardless of
the position of the stand-by switch. With the RIT knob left
in that position, turn the main tuning knob until the slgnal
from the opposite station becomes a zero beat signal (zero
beat signal can be easily noted by turning IF SHlFT knob).
This completes the zeroing of the transmit frequency. Turn
the RIT knob for your desired pitch of sound.

AMPLIFIER
Tune and load the TS-820 as described in Sections 4.1
through 4.1 1 and adjust it for the selected mode.
The REMOTE connector on the back panel is provided for in-
terconnections with an ampliher. See the instruction ma-
nual of the amplifter to determnne whether the linear requires
a normally open (during recelvel or a normally closed (during
receive) relay contact Connect either pin 3 (normally closed
to ground during receive) or pln 5 J m e n to ground
during receive) o i the REMOTE connector to the control jack

on the amplifier.
Connect the ALC feedback from the amplifier to pin
6
of the
REMOTE connector. The output of the TS-820 is quite ade-
quate to drlve mosl amplifiers to full rated output.
4.1 5 FIXED FREQUENCY OPERATION
The T S ~ 8 2 0 has a built-in crystal controlled oscillator for
f ~ x e d frequency operation. This feature is most useful for
commonly used frequencies. nets, or any situation where
crystal controlled operation is required. To use the fixed fre-
quency oscillator, turn the FUNCTION switch to the FIX po-
sition. Select one of the four available channels with the f i ~
xed channel selector switch and tune and load the TS-820
as described in Sections 4.1 through 4.1 1 Simply operate
the transceiver as described in Sections 4.12 and 4.13.
