J7 provides the FSK signal that controls mark/space selection, but
does not include a PTT signal that will switch your 746 from RX to
TX. Without a connection between the PK-232's PTT signal (from one of
the radio ports) to your 746's SEND input, your 756 will not switch
to TX unless you configure WinWarbler and Commander to perform this
function.
I don't understand your assertion that "The CI-V cable won't key
FSK"; if Commander sends your 746 a "transmit" command, your 746
should start transmitting no matter what mode its in. To check this
out, select RTTY in Commander's Main window to place your transceiver
in FSK mode, and then click the PTT panel's TX button; does your 746
start transmitting? If the right side of Commander's Main window
displays the current memory bank rather than the PTT panel, click
the "Filters & Devices" button to make the PTT panel and frequency-
dependent device readouts visible.
