Higher frequency Lower frequency %4 M ANUAL NOTCH FILTER CONTROL [NOTCH] (inner control; p. 83) Varies the notch frequency of the manual notch filter to reject an interfering signal while the manual notch function is ON. • Notch filter center frequency: LSB/RTTY/PSK-R : -1040 Hz to +4060 Hz USB/RTTY-R/PSK : -1060 Hz to +4040 Hz CW : C W pitch freq. -2540 Hz to CW pitch freq. +2540 Hz AM : -5100 Hz to +5100 Hz Higher frequency Lower frequency %5 RIT SWITCH [RIT] (p. 73) ➥ Push to turn the RIT function ON and OFF. • Use [RIT/∂TX] control to vary the RIT frequency. ➥ Push and hold for 1 sec. to add the RIT shift frequency to the operating frequency. ✔ What is the RIT function? The RIT (Receiver Incremental Tuning) shifts the receive frequency without shifting the transmit frequency. This is useful for fine tuning stations calling you off-frequency or when you prefer to listen to slightly differentsounding voice characteristics, etc. 1 PANEL DESCRIPTION 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 10
