BG5BQB @BG4IJK No, I apologize, I seem to have misidentified the purpose. I thought these sections were for avoiding aircraft, but after checking carefully, I realized they are for amateur satellite services. I just spoke with someone I know, and it seems that the U-band is likely the primary business band that needs to be used. However, I agree with you about the 6m band; I also find it quite unusual.
