[VHFcontesting] XV222 + IC746Pro

[David Pruett]

Peter,

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.

Good luck,

Dave/K8CC
