INTERFERENCE REJECTION(SIGNALS WITHIN 3KHZ)

DIGITAL NOISE REDUCTION (DNR) OPERATION

The Digital Noise Reduction (DNR) system is designed to reduce the level of random noise found on the HF and 50 MHz bands, and it is especially effective during SSB operation. By rotating the [DNR] knob, any of sixteen different noise- reduction algorithms can be selected; each of these algorithms was created for dealing with a different noise profile, and you will want to experiment with the DNR system to find the best setting according to the noise currently being experi- enced.

1.Press the [DNR] button. The “” icon will appear in the display, confirming that the DNR system is en- gaged.

2.Rotate the [DNR] knob to select the setting that most effectively reduces the noise level.

3.To disable the DNR system, press the [DNR] button once more. The “” icon will turn off, confirming that the DNR system is not active.

The Digital Noise Reduction affects the Main band (VFO-

A) only.

DIGITAL NOTCH FILTER (DNF) OPERATION

The Digital Notch Filter (DNF) is an effective beat-cancelling filter that can null out a number of interfering beat notes inside the receiver passband. Because this is an Auto-Notch feature, there is no adjustment knob associated with this filter.

ADVICE:

If a very strong interfering carrier is encountered, we recommend you first use the IF Notch filter, as it is the most effective notching tool in the receiver section.

1. Press the [DNF] button. The “” icon will appear in the display, confirming that the DNF system is engaged.

2.To cancel DNF operation, press the [DNF] button once more. The “” icon will turn off, confirming that the Digital Notch Filter is no longer in operation.

ADVICE:

The Digital Notch Filter affects the Main (VFO-A) band only.
