Icom IC-756 - Manual (Page 32)

When you find 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 find the DX station’s receive fre-
quency.
e When you find 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.
PRACTICAL EXAMPLE
• RIT function
The RIT function shifts the receive frequency up to
± 9.999 kHz in 1 Hz steps (10 Hz steps when can-
celling the 1 Hz step readout) without moving the
transmit frequency.
- See #2 on p. 5 for function description.
q Push the [RIT] switch.
w Rotate the [RIT/ ∂ TX] control.
e To reset the RIT frequency, push [CLEAR] for 2
sec.
r To cancel the RIT function, push [RIT] again.
- “ ” disappears.
• ∂ ∂ 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 #3 on p. 5 for function description.
q Push the [ ∂ TX] switch.
w Rotate the [RIT/ ∂ TX] control.
e To reset the ∂ TX frequency, push [CLEAR] for 2
sec.
r To cancel the ∂ TX function, push [ ∂ TX] again.
- “ ” disappears. ∂TX TX RIT RIT
NOTE: When RIT and ∂ TX are ON at the same time, the [RIT/ ∂ TX] control shifts both
the transmit and receive 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 frequency,
push [RIT] or [ ∂ TX] for 2 sec.
