Correct; the 847 doesn't do VOX, but I believe the SignaLink does.?
That was the only way it made sense to me that things were working.?
The SignaLink was keying the rig via its own internal VOX, and the
CAT, while also keying the rig, was overruled by the rig seeing PTT
on the Data port so getting the audio signal from there.?
If setting WSJT-x to VOX still has the 847 going into transmit, it
must be due to the SignaLink providing that function.? From what you
write, making only the change to the WSJT-x software for VOX did
nothing?? THAT I can't explain.? If the only PTT being recognized by
the 847 was coming from CAT, and the audio only coming in from the
Data port, that shouldn't have worked unless the signal was really
really loud.? What was it set to?

Tim,
I took up your request to test the keying my radio using a
SignaLink and VOX.? My Audio is fed from the SignaLink to the
radio using the SLCAB847 cable, plugged into the Data In/Out jack
located under the HF SO239 connector.
I wasn't able to complete the test VOX keying with SignaLink audio
because the FT-847 does it does not support VOX.? I searched the
manual and the internet before coming to that conclusion.? Using
WSJT-X I tested the remaining two PTT options, DTR & RTS, and
my radio would not transmit with either of those selected.? The
only way that I can make my radio transmit is by using CAT PTT.
I also tested a couple of older AFSK programs with my SignaLink
and CAT control.? Testing with FLDigi, my radio would transmit as
long as I select FLRig as the rig control option, and FLRig is
configured for the FT-847 with the COM port & baud rate set.?
I also tested DigiPan and the radio will transmit if I select the
COM port that is connected to the radio.? It's interesting to note
that DigiPan does not have a setting for the baud rate, but it is
set in my computer to match the rate that my FT-847 is configured
for.
