Yes it is. But it is not only done for one frequency, it is done for
all frequencies in the band.

well regarding the sideband issue, my understanding
is that it was done that way because of the technical
limitation of the mixer or sideband filtering method
of the rigs back then would no allow the lower

We are using the SAME version.
As I see it, using 0 for input and 2 for output should work for you.
It it does not, I am afraid it is a strange Windows quirk
