RECEIVE AND TRANSMIT
4-11
Side Tone Level (Default: 50%)
Select the CW sidetone output level.
• 0 to 100% can be selected.
Side Tone Level Limit (Default: ON)
Set the CW sidetone level limit. When the [AF]
(L)
control is rotated above a specified level, the CW
sidetone does not increase.
• OFF: CW sidetone level is not limited.
• ON: CW sidetone level is limited.
Keyer Repeat Time (Default: 2sec)
When sending CW using the repeat timer, set the time
between transmissions.
• 1 to 60 seconds in 1 second steps can be selected.
Dot/Dash Ratio (Default: 1:1:3.0)
Set the dot/dash ratio.
• 1:1:2.8 to 1:1:4.5 (in 0.1 steps) can be selected.
Keying weight example: Morse code “K”
DASH
Weight setting:
1:1:3 (default)
Weight setting:

DOT (fixed*)
Adjustable range SPACE (fixed*)
Rise Time (Default: 4ms)
Set the rise time of the transmitted CW envelope.
• 2, 4, 6 or 8 milliseconds can be selected.

Key clicks on nearby frequencies can be generated if
the rise time of a CW waveform is too short.
Paddle Polarity (Default: NORMAL)
Set the paddle polarity.
• Normal or reverse polarity can be selected.
Keyer Type (Default: ELEC-KEY)
Select the keyer type for [ELEC-KEY] connector on the
controller.
• Straight key, BUG-KEY or ELEC-KEY can be select-
ed.
Regardless of this setting, the [KEY] connector of
the Main unit is for only a straight key.
MIC Up/Down Keyer (Default: OFF)
Set the microphone [UP]/[DN] switches to be used as
a key. (The microphone [UP]/[DN] switches do not work
as a “squeeze key.”)
• ON: The [UP]/[DN] switches can be used as a key
for CW.
• OFF: The [UP]/[DN] switches cannot be used as a
key for CW.
• When “ON” is selected, the frequency and memory
channels cannot be changed using the [UP]/[DN]
switches.
• The optional HM-151 microphone cannot be used
as a MIC Up/Down Keyer.
