2)
Rotate
INCREMENTAL TUNING
CONTROL
counterclockwise.
Receive : 14.2639MHz
Transmit: 14.2678MHz
2)
The receive frequency
can be shifted
in
10Hz
steps by adjusting
the INCREMENTAL TUNING
CONTROL.
Rotating the control
in the
(+)
direction raises the
receive frequency,
and in the {—
)
direction lowers
it.
3)
To
turn OFF
the
RIT
function,
push
the RIT
SWITCH again.
The
letters
"RIT"
and the amount of shift are
no longer
dis-
played.
4)
When the
RIT circuit
is
OFF,
the
transmit and
receive frequencies
are the
front
panel
displayed
frequency.
They
are the
same
regardless of
the amount of
shift
previously
selected
with the
INCREMENTAL
TUNING
CONTROL.
However,
the RIT
shift
value
is stored
in a memory for
later
use when
the
RIT function
is
again
activated.

To
clear
the
RIT shift, push the RIT/zITX
CLEAR SWITCH.
The
shift
value resets
to 0.0
and
the receive and
transmit frequencies
become the same whether
the RIT function
is ON or
OFF.

The
ATX
circuit
allows the transmit frequency
to
be shifted
up
to
9.9kHz
to
either side of the receive frequency
without moving the
receive
frequency. This
function
is similar in operation
to
the RIT
function.
