First we presume you are connecting via the AUX DIN connector on the rear
panel. And via the MENU you have selected AUDIO SOURCE to be LINE. Then
the next line below on the MENU the LINE GAIN set to about 35% to 50%.
The interface must provide a PTT command to this connector as well.
Yes, you will need RS-232 communications to get frequency info and control
other functions on the radio. For RS-232 communications, I've abandoned all
efforts to use a USB to RS-232 interface and opted to install a real RS-232
card in the computer with a fully populated DB-9 to DB-9 cable between the
radio and the computer. Lif is so much easier.
For audio, I use either the Tentec 712 USB Soundcard interface or the
SignaLink USB interface very successfully.
Since WSJT-X stopped working, I'd suspect the configuration in the computer
is not selecting the correct sound card.
Be sure the CAT software is not using a hardware PTT command and thus one
would use the PTT command from the soundcard. If all else fails for PTT,
just use VOX.

Subject: [TenTec] OMNI VII and digital modes issue
Hello all,
I wonder if anyone has been through this before? I have successfully used
digital modes for some time with a Yaesu FT857D.
I have been trying a couple of different ways to get my OMNI VII to run
digital modes with no complete success so far.
I have tried a sound card interface (EASY DIGI) using a connection to the
ACC1 socket and it receives properly and displays signals on the
waterfall. Also it will KEY the rig to transmit but there is no audio
even though the computer is sending audio into the interface.
Also it would not read the VFO from this port (obviously) - so I tried
also connecting an RS232 serial signal from the 9 pin serial plug on the
back of the OMNI VII. Now I can read the VFO but still can;t transmit
digital.
Now it will not key the rig on transmit. I tried using DTR instead of RTS
to see if that would help Neither one does it.
Oddly the waterfall stopped running in WSJT-X after doing some pretty poor
decoding (compared to what I am used to seeing) - it was showing
signals -however the display looks odd.
I have tried testing rig control and testing PTT in WSJT-X fr the OMNI 588
and both fail.
I am going through the manual to see what the settings should be for the
RS232 going into the OMNI VII. The odd thing is that I can now read the
VFO OK using SKCC logger so I now the interface works.
Best regards - Brian Carling, AF4K
