19. EDSP Filters

(A) APF

Selects and indicates the bandwidth for the EDSP CW audio peaking filter. Pressing the [APF] switch se- lects the bandwidth to be used for the EDSP CW audio peaking filter, with available selections of 240(Hz)/ 120(Hz)/60(Hz)/DATA (DATA is an optimized bandwidth for FAX, PACKET or SSTV operation, user-optimized via the Menu), or “OFF,” and the indicator changes ac- cording to the bandwidth selected. The most narrow setting is highly useful for very-weak-signal CW work.

(B) NR

Selects and indicates the setting of the EDSP Noise Reduction feature. Pressing the [NR] switch selects one of four EDSP noise reduction settings, and the indicator changes according to the selection chosen (choose the selection providing the most effective re- duction of noise under current operating conditions).

(C) CONTOUR

Press one of these four switches to select the de- sired EDSP (CONTOUR) filter.

: Low Cut Filter (High-frequency emphasis) Pressing this button activates the EDSP Low Cut Filter; the CONTOUR LED will glow green.

:Mid Cut Filter (High- & Low-frequency emphasis) Pressing this button activates the EDSP Medium Cut Filter; the CONTOUR LED will glow orange.

: High Cut Filter (Low-frequencies emphasis) Pressing this button activates the EDSP High Cut Filter; the CONTOUR LED will glow red.

OFF:

EDSP filter is off; the CONTOUR LED will go out.

20.MODE Selection Buttons

These momentary buttons select the operating mode, indicated by the LED in each button. Pressing AM, CW, RTTY, or PKT multiple times will switch be- tween the alternate operating features that can be used by these modes (covered later). Also, when you press and hold in the [PKT] key for one second, the user- programmed custom function setting mode will be ac- tivated.

21. CLASS-A Button

This button changes the final amplifier operating mode to Class-A. When operating the final amplifier in the Class-Amode, the maximum output power will be reduced to approximately 75 watts, and the LED inside this button will glow red. Operating SSB in Class- A yields an ultra-clean signal waveform.

22.FAST Button

For fast tuning, press this button (the “FAST” icon will appear), then rotate the main or sub tuning knobs (or press the UP(p) or DOWN(q) button). The tuning rate will increase ten times.
