So i should be happy, the planes i fly have no rdr alt mess? :D
Last week i didnt see traffic passing me from right, same alt. Only after atc tells me traffic 12 o'clock half mile i saw him with very bad contrast to sun and clouds bihind him.
Pay much more attention while flying with small seperation is always a good idea i think :D
But it's a nice detail! Bad, i cannot use the RSBN navigation - only ADF works fine.
