DANF (Automatic Notch Filter) function

This function automatically attenuates beat tones, tuning signals, etc., even if they are moving. The automatic notch filter functions in SSB, FM and AM modes.

Select S4 (DSP menu).

Push [DISPLAY] 1 or 2 times when M or G is displayed.

Push [MENU] one or more times to select S4.

Push [(F-1)ANF] to toggle the automatic notch filter ON and OFF.

DNR (Noise Reduction) function

This function reduces noise components and picks out desired signals which are buried in noise. The received AF signals are converted to digital signals and then the desired signals are separated from the noise. The noise reduction function is available for all operating modes.

Select S4 (DSP menu).

Push [DISPLAY] 1 or 2 times when M or G is displayed.

Push [MENU] one or more times to select S4.

Push [(F-2)NR] to toggle the noise reduction func-

tion ON and OFF.

“DSP” and “NR” appear when the function is ON.

Push [(F-3)NRL] to toggle the noise reduction level indication ON and OFF.

Rotate the [M-CH] control to set the noise reduc- tion level.

Set the control for maximum readability. Deep rotation results in audio signal masking or distortion.

NOTE: Pushing [(F-3)NRL] automatically turns the noise reduction function ON, however, the trans-

ceiver maintains the ON/OFF condition when pushing [(F-2)NR].
