CW RISE TIME
The CW signal rise time is a period required for the output
waveform of the CW signal to reach its maximum from
when the key is pressed down. The default value (6 [ms])
is suitable to low- to mid-speed keying. Select "4 [ms]", "2
[ms]", or "1 [ms]" for high-speed keying.
1 Select Group No. 5, "CW Configurations", from the
Menu screen.
2 Access Menu 14, "CW Rise Time".
3 Press [SELECT] (F4) to allow editing of the parameter
box.
4 Press [–] (F4) or [+] (F5) to select "1 [ms]", "2 [ms]", "4
[ms]", or "6 [ms]".
The default is "6 [ms]".

ADJUSTING THE SIDETONE AND PITCH
FREQUENCY
You can hear the tone from the speaker of the transceiver
when you press down the key while in CW mode. This
tone is called sidetone. You can monitor your Morse code
transmission by listening to the tone. While Break-in or
other transmit capabilities are disabled, you can use the
tone to practice keying.
In CW mode that require the direct keying of the carrier,
a BFO (beat frequency oscillator) is required to convert
the carrier into audible sound. The difference in frequency
between the BFO and carrier is audible as a beat sound.
The difference in frequency is called receive pitch.
The sidetone and receive pitch are the same in frequency.
You can turn the CW PITCH control to adjust the
frequency of the sidetone to your preference.
The adjustable frequency range is between 300 and
1100 Hz, and turning the CW PITCH control clockwise
increases the frequency and counterclockwise decreases
the frequency.
