The only reason you would HAVE to run Mode=Rig Split on WSJT-X is if your rig
doesn't behave well on Fake It.Generally speaking rigs will behave a bit better
in Rig Split.
If you are saying you don't run Fake It either then you are risking harmonics
and/or power loss. Split and Fake It both prevent harmonics and power loss
from from passband edges.
There's additional advantage to Rig Split....you can (if your rig supports) is
band pass the TX side from 1400-2200 (giving yourself a little extra room at
the top for wider modes).

Zeev,
I don't really understand your point - why are you setting the rig for spilt
operation? I sometimes worry that the use of the word "split" immediately
brings to mind the "Up 1 KHz" CW mindset. I work FT8 "spilt" all the time but
I never ever put the radio itself in "Split" mode. All "split" means in FT8
is that you are transmitting on a different audio frequency than the one on
which your are receiving. And that does not involve VFO-B or invoking the
"Split" option on the radio.
The word "split" in FT8 means the same thing as in CW or SSB in that you are
transmitting on a frequency different from that on which you are receiving.
But having said that, the means to achieve that "split" are completely
different.between FT8 and CW or SSB.
Maybe I am missing something. Please help me understand why I would want to
physically place the radio in "split" when running FT8

When using Omni-Rig, I believe WSJT-X Does not control the operation mode of
the IC-7300 regardless of the "Split Operation" selection.
As far as I can tell, WSJT-X assumes the user is responsible for selecting
"USB-D" for both VFO-A and VFO-B.
Here is a scenario that demonstrated this:
- Change the operation mode to "LSB" using the touch screen- Change the
frequency a bit using the VFO knob- Start WSJT-X- Set "Split Operation" to
"None" using File -> Settings... -> Radio
- Select the current band in WSJT-X
- Verify that the proper frequency is set- Notice that the mode remains "LSB"-
Select the "CQ" Command- Click the "Enable Tx"- Notice that the mode remains
"LSB" during the transmission
- Click "Halt Tx"
- Notice that the mode remains "LSB" after the transmission
An Omni-Rig log file, created when Omni-Rig was working exclusively with
WSJT-X, is available at
