rSet the desired condition using the main dial.

•Push and hold [F-4•DEF] for 1 sec. to select a default condition or value.

•Push [F-3•Ω ≈] to select the set contents for some items.

t Push EXIT/SET to exit from set mode.

RTTY FFT Scope Averaging OFF

Select the FFT scope waveform averaging function from 2 to 4 and OFF. (default: OFF)

Recommendation!

If you use the FFT scope waveform for tuning, use the default or smaller number setting is recommended.

RTTY FFT Scope Waveform Color 51 153 255

Set the color for the FFT scope waveform.

•The color is set in RGB format.

•The set color is indicated in the box beside the RGB scale.

•Push [F-3•Ω ≈] to select R (Red), G (Green) and B (Blue), and then rotate the main dial to set the ratio from 0 to 255.

	RTTY Decode USOS	ON
Turn the capability of letter code decoding after re-		• ON	: Decode as letter code.
ceiving a “space” (USOS; UnShift On Space function)		• OFF	: Decode as character code.
ON and OFF.
	RTTY Decode New Line Code	CR,LF,CR+LF

Selects the new line code of the internal RTTY de- coder.

CR: Carriage Return, LF: Line Feed

• CR,LF,CR+LF : Makes new line with any codes.

• CR+LF : Makes new line with CR+LF code only.

	RTTY Diddle	BLANK
Selects the diddle condition.		• BLANK	: Transmits blank code during no code
			transmission.
		• LTRS	: Transmits letter code during no code
			transmission.
		• OFF	: Turns the diddle function OFF.
