Johnny,
are you deliberately trying to confuse here? First you say using SPLIT
on a rig has no place with FT8, then here you say you do exactly that.
Make up your mind!

Mike,
I always run Fake it or Rig split - great feature and yes, it keeps
the signals clean and preseves power just like ti is supposed to. I
run my Tx bandpass up to 3000 - I could go higher but most of the
older rigs struggle so not much point.

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
