Icom IC-756 Marine Radio User Manual


 
When you 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 find the DX stations receive fre-
quency.
e When you nd the DX stations receive frequency, push
[RIT] to turn the RIT function OFF.
- Now you can transmit the DX stations receive fre-
quency and receive the DX stations 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.

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.
