FUNCTION FOR RECEIVE

■
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.

The function shifts the receive frequency up to ±9.999
