I am trying to rename my Sat Receiver for Galaxy 12 and Galaxy 18 on 123.0W. The Lyngsat Map List for North and South America lists then as G12 and G18, BUT the detailed Lyngsat Tp Frequency Listing as well as Mike Kohl's list has them BOTH as Galaxy 18?? Can someone please tell me which one is for C Band and which one is for Ku Band?
