A few nights ago I got my J-38 out to help with Straight Key Night.
(Had a blast!).

The J-38 isn't particularly new to me... I got it from my Elmer before
I was licensed, probably when I was 9 years old.

But... as I look at it, I see it has a screw eye and two posts in the
back, and realize that I never knew what they were for. The two posts
in the back might be some kind of shield tie-down (or maybe something
I have no conception of related to land-line telegraph wiring), but
what the heck is the screw eye there for?
