Lol! Doh!
Yes I had the spherical selected and now understand why the quiet zone is where it is
That said I still think the SHM is 180 degrees out. No matter which array I select the down arrow with the trailing line seems to be 180 degrees out. To me that line on the display is there to let you see which way your ship is pointed.
I'm sure 688i didn't have this problem or I would have noticed. Will have to break it out just to check.
Thanks
