MORSE CODE DECODER
The decoded character strings are displayed on the
sub-display (up to 8 characters) by decoding the
received Morse code.
1 Press [CW/FSK (REV)] until you select CW mode.
• “CW” appears.
2 Press [DATA] to toggle the Morse Code Decoder
ON and OFF.
• “
” appears when the Morse Code Decoder
is ON.
• Whenever one character is decoded, the
character is displayed from the right end in Sub-
display.
THRESHOLD LEVEL ADJUSTMENT
Adjust the threshold level in order to reduce the
infl uence of the signal strength and external noise,
adjust the threshold level.
1 With the Morse code decoder ON, press and hold
[DATA].
• Threshold Level Setting mode starts. “ ” will
blink and the current number display and meter
display levels will blink.
2 Turn the MULTI/CH control to set the threshold
level.
• Adjust the threshold from 1 to 10 for weak
signals in which the S-meter does not show any
defl ection.
• Adjust the threshold from 11 to 30 for strong
signals in which the S-meter defl ects the
needle.
3 Press [DATA (REV)] or [CLR] to exit the threshold
level adjustment mode.
Note:
◆ The keying speeds range from 4 to 60 wpm.
◆ The weighting ranges from 2.5 (1:2.5) to 4.0 (1:4.0).
◆ There are eight corresponding abbreviations: BT, AR, AS,
HH, SK, KN, BK, and SN.
◆ The split-frequency and RIT/XIT frequency are not displayed
during this function.
◆ The setting mode is displayed by priority in setting modes.
When the setting modes are fi nished, the most recent
decoded character strings are displayed.
◆ Depending on radio wave conditions (noise, fading, signal
interference, etc.), decoding may not be performed correctly.
◆ If the keying speed of the target signal changes during
reception, the character immediately before and after the
changed speed will not be decoded correctly.
◆ Characters that cannot be decoded are displayed as
underscores.
◆ Available alphanumeric characters that can be displayed are
listed below.
0 1 2 3 4 5 6 7 8 9 A B C D E F G H I J K L M N O P Q R S T
U V W X Y Z / @ ?.
◆ The number 0 is displayed by entering a slash.
◆ This function does not work with message playback that is
recorded.
