RR, looking at the rig's manual I see
that this one is capable of the same maximum Rx bandwidth of 3000
Hz in both USB and USB-DATA modes. So there is no need in this
case to use different modes for Tx and Rx. In which case with
FT-450D I would recommend the following settings in WSJT-X:
This will allow WSJT-X to set the rig's
mode and also gives the most efficient T/R switching.

the WSJT-X "Settings->Radio->Transmit Audio Source"
options are greyed
out for your rig because the selection of the Tx audio input
rig is determined by the DATA mode of the rig. In USB-DATA
audio is taken from the rear DATA jack, in USB it is taken
from the MIC
Some Yaesu rigs have limited Rx bandwidth in USB-DATA mode,
even if the
rig menu settings are adjusted for the maximum width. This
unfortunate but you can work around it with a small
the WSJT-X "Settings->Radio->Mode->None", and the
"Settings->Radio->Split Operating->Rig" options.
WSJT-X will utilize
SPLIT on your rig to optimize the transmit. All you need do
your Tx VFO is in USB-DATA mode and your Rx VFO is in USB
gives the correct Tx audio source while maintaining maximum
