I know I read about this topic several weeks ago but I can't find it when I search. I had my new EC93SV+ out this week for its first real trip. Using a split screen for Clear Vu and Side Vu the Clear Vu was noticeably darker to the point it was almost unreadable. The Side Vu was great. I was on auto brightness and changed to manual 100% and there wasn't much change. What other adjustment could I try? Clear Vu was on 455 kHz.
