If the TS-990 radio control is via USB, it is probably using the TX1;
command - particularly if COMM PTT = YES - which is equivalent to the
microphone PTT. The microphone PTT mutes the data (ACC) input and can
be responsible for the "no audio".
Try unplugging the separate PTT cable and see if you don't still have
PTT. If so, it can only be the TX1; command.
Unless I missed something, in RttyRite, per se, there is no control
for PTT, although the XMMT setup in Rttyrite will take you to MMTTY
where you can configure which comport controls PTT.
Since you are using XMMT.ocx, set the Rttyrite Port to *None* and
click "Option | Setup" in the RTTY control Panel. Now select the TX
Tab and set the PTT & FSK port to the port to which your PTT interface
(the Donner?) is connected. Make sure Tx Port on the Misc tab is set
to Sound (for AFSK) and the "PTT & FSK" port will bee used only for
PTT (on both DTR and RTS).
One last thing ... you may need to set COMM PTT to "NO" if there is a
conflict between the TX1; command and hardware PTT on PKS.
These notes are based on *other* Kenwood rigs and a simple transistor
PTT interface - since I have not worked with either the Donner or the
TS-990 - and "basic principles" of XMMT.ocx, Writelog and Kenwood
interfacing.

Appreciate your responses, although I confess that much of what you said
is above my pay grade - hi.
In my setup, PTT is NOT on the same port as CAT control:
Radio control of the TS-990 is via USB, not RS-232.
PTT is via RS-232.
So they are separate.
I have no idea how to control PTT from XMMT.ocs.
The source of XMMT.ocs, I believe, is the new version of Writelog. If
I'm wrong, someone correct me.

But I remain confounded by the fact that MMTTY standalone works fine
with the TS-990, but Rttyrite (in Writelog) will key the radio but
furnish no audio or generate RF out of the radio.
