Rit Function - Icom IC-756PROIII Instruction Manual

■ RIT function

The RIT (Receive Increment Tuning) function com-
pensates for off-frequencies of the communicating
station.
The function shifts the receive frequency up to ±9.999
kHz in 1 Hz steps (10 Hz steps when cancelling the 1
Hz step readout) without moving the transmit fre-
quency.
• See #1 on p. 5 for function description.
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.

1 sec.
• Push [CLEAR] momentarily to reset the RIT frequency
when the quick RIT/∂TX clear function is ON. (p. 103)

• Practical example
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
frequency.
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.
