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.
Mike,
you might want to reword that paragraph. Using SPLIT on the rig, i.e.
checking the "Settings->Radio->Split Opertating->Rig" option in WSJT-X,
is preferred. The "Fake It" option is a fallback if CAT control if your
rig's SPLIT function is unreliable or unavailable. The reason that using
the rig's SPLIT mode is preferred is that there is no doubt exactly when
the VFO dial frequency is changed since the rig times the change exactly
coincident with switching between Rx and Tx or vice versa as an atomic
operation. With "Fake It" mode there is less certainty that the start or
end of transmission coincides with the correct VFO dial frequency being
set, this can lead to CAT control errors or inaccuracies with some rig
models and with external PTT switching options.
