CW Keyer Interface

The CW keyer is specifically designed to work with a DTR/RTS keyline to emulate the closure of a CW key. Several transceivers have this capability built in to the hardware. Some expose a separate keying port (FT-991A) and some share the CAT serial port (IC-7300). A simple DTR/RTS keying circuit can also provide the h/w interface. This one provides galvanic isolation:

PTT delay is in milliseconds. Enter a non-zero value to enable a delay between the PTT-on and the first CW keyline closure. The same delay will be applied to the last CW keyline closure and PTT-off.
