Welll... Shucks! I was just getting ready to volunteer my tower as a
place to store the LDF-5.<:-))
I'm going to store a HAM-IV on it for one friend and it'll turn my C-19
XR while there. Unfortunately, or maybe fortunately, I discovered the
inside is full of sand....Well, not full, but there is plenty enough to
cause a short life. It's in everything. The bearings look like they were
rolled in it. So I have to do a clean and grease, PLUS replace or fix
the broken terminal strip on the bottom which is where the sand got in.
OTOH the outside now looks like a new rotator of the proper gray color.
