QRSS from Rik Strobbe. One modem line to PTT and one to indicated dots or dashes. This is a 0 to 5v signal which will probably work with the circuit attached. I suggest try it before going to the trouble of shifting the levels to avoid 0v as I suggested earlier. The cap (trimmer) will probably need to be very small.
