Mortty v5 is a full-featured, inexpensive, hardware solution for precision CW and RTTY keying. It supports both CW and TinyFSK RTTY modes, selectable via a slide switch on the rear panel. The device runs both modes from a single firmware—no need to swap sketches as required in previous versions of Mortty. Detailed information about Mortty V5 is located at the Mortty V5 website:
