3-2-2. CW zero-beat operation
Zero-beat operation with a station during CW mode
operation
1. Set the RIT/XIT switches to OFF.
2. When an optional filter is not used, tune the TUN-
ING dial so that the receive beat frequency is ap-
proximately 800 Hz. You can check this by turning
the VOX OFF, and then closing your CW key. Then
by using the sidetone oscillator, and the incoming
receive signal you can zero-beat by turning the
TUNING dial until the two tones are the same fre-
quency.
3. When the YK-88C filter is used the simplest method
to use is to adjust the TUNING dial for a maximum
S-meter deflection.
Reception at the desired pitch after zero-beat
operation.
1. After zero-beating turn the RIT switch ON, and ad-
just the RIT control for the desired pitch.
2. Adjust the IF SHIFT control for the strongest sig-
nal level.
3-2-1. Initial setting
1. Preset the controls as shown in the accompanying
illustration above.
2. Place the POWER switch to ON. (During fixed-
station operation you must first turn ON your DC
power supply, the PS-50 is recommended.)
3. The meter will illuminate and a frequency will ap-
pear in the display.
4. Set the BAND switches for the desired band. If you
desire to tune a frequency other than one of the
amateur radio frequencies, place the 1 MHz switch
ON. With the 1 MHz switch ON the UP/DOWN
switches will advance the frequency in 1 MHz
steps, rather than thru the amateur radio bands.
5. Select the desired MODE using one of the mode
switches.
Notes:
1. By international convention amateur radio fre-
quencies below .1 0 MHz utilize the LSB (Lower
Sideband) mode, and frequencies of 10 MHz
and above use USB (Upper Sideband).
2. The TS-440S automatically selects the normal
mode for you. The exact changeover point is
9.5 MHz. You can override this selection by
pressing the desired mode switch.
6. Adjust the AF gain control tor the desired volume.
7. Slowly rotate the TUNING dial until the desired sig-
nal can be heard clearly.
8. The desired receive frequency can also be entered
directly by using the numeric keypad. For details
of this operation please refer to the "Direct key-
board frequency entry" section on page 13.
