Principle - arduino keyer identifies the played characters (enabled echo feature in K3NG code) and sending to server for playing with other hardware of the cw keyer or cw daemon (contains RemoteQTH server for Raspberry PI). This configuration is resistant to change internet latency during transmission, because not transmitted separately each dit/dash, but the entire ASCII character that perfectly transmiting the server side.

Main functions:

• CW keying
• Detect keying characters and show on the LCD
• Send keying characters to USB serial (echo mode)
• CW sidetone during the PTT is ON, otherwise play audio from RX
• Sidetone volume
• Four SET/MEM switch
