RigPi Keyer is a versatile Morse code generator based on the popular K1EL WinKeyer3 IC. It connects to the Raspberry Pi through the GPIO header and uses the onboard serial port, ttyS0.

Connect to you transmitter keying input. |
RigPi Keyer can be used with a paddle or straight key plugged into the PADDLE jack with or without a radio connected. The KEYER SPEED control works when the keyer is not under RigPi control and when using any of the main RigPi windows.
RigPi Keyer has a PTT switching circuit that normally follows PTT commands from RigPi. You can also use the WinKeyer3 PTT circuit independently through commands. Independent control means that you can use the RigPi Keyer PTT for remote control purposes, such as controlling a power switch. See the Technical RigPi Keyer PTT topic of Help to learn more about extended uses of RigPi Keyer PTT.
Settings
The RigPi Keyer settings are located in SETTINGS>Keyer. Morse can be sent by typing on a keyboard, through a custom Macro, or by means of a keying paddle. It is possible to use a straight key as well as a paddle.
The WinKeyer3 IC has an extensive set of programming commands, many of which are used in RigPi. You can also create Macros using these commands for special purposes.
Remote Keying
When away from home you can use your favorite hand key to send CW from your home station. A second RigPi, external Winkeyer/Raspberry Pi, or RigPi Hub with a Windows program that can key RTS or DTR is required. RigPi does not have to have an Audio board. You can use a paddle, bug, or straight key. Please see the RigPi Remote Keyer topic for details.
