@RIT/XIT control
0 RIT:
First, cancel any previously programmed offset using the
CLEAR key, then turn the RIT switch ON.
The RIT control allows shifting the receiver frequency
± 9.99 kHz. The RIT display will show the offset to the
nearest 1 00 Hz. Use of the RIT control will not affect the
transmit frequency.
When the RIT switch is ON, the RIT indicator will light, and
the receive frequency can be adjusted by using the RIT
control. Pressing the CLEAR switch restores the RIT to
the previous status.
Note: -------------------------------------
When the RIT is ON the transmit frequency may be differ-
ent from the receive frequency. For normal operation
leave the RIT switch OFF. It should be used only when ne-
cessary.
0 XIT (Transmitter Incremental Tuning)
Transmitter Incremental tuning is very similar to RIT (Re-
ceiver Incremental Tuning). XIT is only active in the trans-
mit mode. By using the XIT function it is possible to offset
the transmit frequency without the normal loss of receiver
audio that is experienced when using the SPLIT function.
Offsets of ± 9.9 kHz are possible.
The RIT /XIT offset can be preset, without affecting the ac-
tual operating frequency by turning OFF the XIT /RIT and
using the RIT /X IT display to determine the offset.
e
AFTUNE
The AF TUNE circuit is just the opposite of the NOTCH cir-
cuit. With this control it is possible to accentuate the de-
sired signal by providing additional rejection of noise and
interfering signals whose pitch (tone) falls outside the au-
dio passband.
Turn the AF TUNE switch ON and adjust the AF TUNE
control to peak the desired signal.
• ®PITCH control
The CW PITCH control is provided so that you may adjust
the pitch or tone of the incoming CW signal so that the
tone is pleasing to you. The TS-940S accomplishes this
without shifting the actual transmit or receive frequency,
by shifting the 1 00 kHz IF frequency, just prior to Product
Detection.
