(3) XIT
By using XIT, transmit frequency can be shifted independent
of receive frequency.
With the XIT switch ON, the XIT is controlled by the RIT/XIT
knob and transmit frequency can be shifted by about +2
kHz. When both the RIT and XIT switches are ON, both
receive and transmit are shifted without adjusting the main
tuning.
(4) MONITOR
To monitor transmitted SSB signal quality, turn the
MONITOR switch ON to sample and demodulate a part of
the transmit IF signal.
This feature is useful for checking modulation, or when
adjusting the speech processor.
When monitoring, use a headphone to avoid audio feedback.
NOTE:
If the HEATER switch is OFF or the DRIVE control is in-
correctly adjusted, the ALC circuit will not operate properly,
causing excessively high transmit IF signal level, resulting in
a distorted monitor signal.
(5) CW OPERATION (fig. 4-13)
Tune and load the TS-830S as described in Sections 4.3.
Using shielded line, connect a key to the rear panel KEY jack,
set the MODE switch to CW. and set the stand-by switch to
SEND for transmitting.
CW transmission is automatically monitored through the
transceiver's speaker. Sidetone audio gain can be adjusted
through the opening in the bottom cover.

(i) Reception
The TS-830S operates in two different CW modes:
WIDE and NARROW. In the WIDE mode, the SSB filter
(pass bandwidth 2.4 kHz, —6 dB) and an audio filter are
used.
20
In the NARROW mode, option CW filters (YK-88C,
YK-88CN, YG-455C, YG-455CN) may be used to nar-
row the IF pass bandwidth to 500 Hz (—6 dB) or 250
Hz along with the audio filter. In both modes, high
frequencies are cut so the received signal willbe more
easily copied.
B@ OPERATION WITHOUT CW FILTERS
To receive CW, set the IF SHIFT control to its center position
and the RIT switch to OFF. Adjust the main tuning for about
an 800 Hz beat and your transmit frequency will be tuned
(zeroed) to the transmit frequency of the station you are
receiving. If the O beat cannot be obtained easily, adjust the
IF shift knob, then return the mode switch to CW. The
transmit frequency of the unit is adjusted to that of the mate
station. You may now adjust the RIT for a pitch which suits
your preference. If interference is encountered, adjust the IF
SHIFT. For more convenient and effective CW operation,
use of the optional CW filters is recommended.
@ OPERATION WITH CW FILTERS (OPTION)
Set the IF SHIFT to its center position and the RIT OFF.
Adjust the main tuning for maximum S-meter deflection.
Receive signal pitch will be about 800 Hz, indicating correct
tuning.
@ KEY CONNECTION (Fig. 4.14)
Your key should be connected as illustrated in Fig. 4-14.
When using an electronic keyer, make sure that polarity is
correct. Use shielded line from the key to transceiver.
NOTE:
When using an electronic keyer, set polarity of the keyer for
NEGATIVE keying.
