FUNCTION FOR TRANSMIT
■
∂
∂
TX function
The
∂
TX function shifts the transmit frequency up to
±9.999 kHz in 1 Hz steps (10 Hz steps when can-
celling the 1 Hz step readout) without moving the re-
ceive frequency.
• See
@9
on p. 5 for function description.
q

switch.
• “
” and the shifting frequency appear when the
function is ON.
w
Rotate the
[RIT/
∂
∂
TX]
control.
e
To reset the
∂
TX frequency, push
[CLEAR]
for
1 sec.
• Push
[CLEAR]
momentarily to reset the RIT frequency
when the quick RIT/
∂
TX clear function is ON. (p. 103)
r
To cancel the
∂
TX function, push
[
∂
∂
TX]
again.

When RIT and
∂
TX are ON at the same time, the
[RIT/
∂
∂
TX]
control shifts both the transmit and re-
ceive frequencies from the displayed frequency at
the same time.
• Calculate function
The shift frequency of the (RIT or)
∂
TX function can
be added/subtracted to the displayed frequency.
While displaying the (RIT and/or)
∂
TX shift fre-
quency, push (
[RIT]
or)
[
∂
∂
TX]
for 1 sec.
• Practical example
When you
fi
nd a DX station on 21.025 MHz/CW and
the station is picking up stations transmitting slightly
up from 21.025 MHz.
q
Push
[RIT]
and
[
∂
∂
TX]
to turn both the RIT and
∂
TX functions ON.
w
Rotate
[RIT/
∂
∂
TX]
to
fi
nd the DX station’s receive
frequency.
e
When you
fi
nd the DX station’s receive frequency,
push
[RIT]
to turn the RIT function OFF.
• Now you can transmit the DX station’s receive fre-
quency and receive the DX station’s transmit fre-
quency (21.025 MHz).
r
Start transmitting while the station is standing by.
