If the PTC-IIpro is like the PTC-II then the CW keying occurs via the PTT line. You must connect the PTT line to the transceiver key input (rather than the PTT line) in order to key it in CW mode. Since your transmitter is keying but no output, I assume that you have the PTC-II's PTT connected to the transmitter's PTT input rather than the CW key input.

The audio output of the PTC-II also has an on/off keyed tone (at the set mark frequency) so you could use that tone to modulate the transmitter in USB or LSB mode in order to generate a CW signal.

Using the CW Key line is likely the better option.
