RIT control
When the transmit frequency of the distant station
drifts a little bit during the QSO, but you do not wish
to alter your transmit frequency to compensate, you
may wish to make use of the RIT control function. This
control allows shifting the receive frequency without
shifting the transmit frequency. The RIT control allows
you to shift the receiver frequency. This control is also
useful for pileups when the DX station is transmitting
a little above or below his receive frequency.
Notes: 2
1. The RIT offset is displayed on the main display. You
can therefore preset the offset before you actually
need to use it. When you move to another station
make sure you turn OFF the RIT switch.
2. The figure below illustrates that the RIT display and
the VFO display may not agree exactly in all in-
stances since the RIT and VFO tune in 20 Hz steps.
The main display resolution is 100 Hz, and would
not show a change of 20 Hz. You would need to
change the frequency at least 100 Hz to see an ac-
tual change in this display. (Except FM mode.)

@) IF SHIFT control
The IF SHIFT control ailows you to shift the iF pass-
band of the receiver, without changing the actual
center frequency of the receiver. This contral is use-
ful when there is interference near your center fre-
quency.
Interference from lower frequencies can be reduced
or eliminated by rotating the IF SHIFT control in the
@ direction. This will cause the resulting audio fre-
quencies to have a slightly treble response, i. e. low
cut filter (low frequencies attenuated). Interference
from higher frequencies can be reduced or eliminated
by rotating the IF SHIFT control in the © direction.
This will cause the resulting audio frequencies to
sound a little bassy, i.e. high cut filter (high frequen-
cies attenuated).
