Yes, as well as AFSK. The K3 is a great FSK radio. There are options for numbers-letters shift, inverting tones, adjustable pitch for mark and space and the frequency is based on the Mark tone instead of the suppressed carrier. In addition to computer keying the FSK via pin-1 of the ACCY connector, you can also operate true FSK without the aide of a computer using your CW paddles.
