8.8
Communicating using a CW Message
Continuous Wave (CW) is a radio emission type that is used to send and receive Morse code messages over the air.
CW Message is used to send Morse code messages preconfigured in the transceiver by using the PF keys.
Pressing the CW Message key causes the transceiver to send a CW Message.
The transceiver will switch to analog modulation mode when the transceiver sends a CW Message.
A maximum of 32 alphanumeric characters and symbols can be configured and sent.
The CW Message to be sent can be configured using KPG-169D/ KPG-170D/ KPG-175D. The following functions are
relevant to sending a CW Message.
Function
CW Speed
CW Modulation Delay Time
Audio Frequency
CW Sidetone
Note
• A CW message is always sent in analog mode regardless of the configuration for Zone Type.
• CW specifications are compliant with articles in FCC 90.425 Station Identification and International Morse Code.

CW Speed refers to how fast the CW Message is sent by using Morse code.
CW Modulation Delay Time is the amount of time from when the transceiver starts transmitting until
the transceiver starts sending the CW Message.

Note
If "Off" is configured for CW Modulation Delay Time, the transceiver sends a CW Message
immediately after the transceiver starts transmitting.
Audio Frequency is the frequency used to send the CW Message.
CW Sidetone is the function to emit tones from the speaker while the transceiver sends a CW
Message.
