I just opened a brand new radio from the box, and haven't done anything with it short of scanning a few repeaters for activity while sitting at my desk. This evening, when I finally decided to to take a closer look at it, I noticed this flat mark along the seam at the tip of the YHA-68. I was just curious if anyone else has come across this aspect before, and if so, is it simply a normal byproduct of the rubber molding process?
