I use a IC-746Pro also, but have never connected a transverter to it.
"Commander" (whatever that is) may have a command to set the display
offset, but the IC-746Pro CI-V protocol does not support it so it won't
work. I've never seen an Icom supporting display offset. Some Yaesus,
yes. Some Kenwoods, yes. But no Icoms.
I was not aware of the command to turn down the power output on the
IC-746, and while I'm not certain, based on the way the IC-746 manual
describes the command, I'll bet it affects all bands
You will have to set up the XV222 for common rx/tx IF, because the
IC-746 lacks a receive antenna input. With a common IF, if you plan to
add an attenutation you'll have to build some sort of relay system to
switch it out of line on receive.
222.0 - 223.7 won't be problem as for contesting you probably only need
222.05 -222.15 unless you're gonna run FM up higher.
