All:
A peculiar thing happened with my Yaesu 2800 rotor controller today. The
rotor kept returning to it's preset position after turning it either
clockwise or counter clockwise. It also moved very slowly.
My first thought was that the preset circuit must be bad, but then I
noticed that the problem went away when I pulled on the preset button.
It turned out that the button itself was jammed. Tapping on it a few
times allowed it to return to it's normal position.
I noticed what appeared to be a tiny piece of plastic which could have
worked it's way into the button causing it to jam. Might be a fluke, but
thought I'd pass it on.

Here?s a question for everyone. I?m installing a new T-base for my crank-up
US Tower so that I can use the raising fixture and stop climbing it when
it?s retracted. (getting too old for that) and I?ve got the holes prepared
and am wondering about the anchoring material to use.
I?ve drilled the holes 2.5? in diameter to account for the nuts at the base
of the anchor bolts, which I?ve had to cut off because I couldn?t go deep
enough. So now I have 2.5? diameter holes to install 1-1/8? anchor bolts in.
My obvious choices are anchoring epoxy, which is expensive at over $20 per
tube, Quikrete anchoring cement, and I just discovered something called
Rockite- for anchoring and patching. I?m hoping that any of these choices
will work. I?d like to save a few $$ and use the Quikrete which will be much
easier to use (mix like concrete and pour into the holes). It has a pull-out
strength of 14,100 psi after 24 hours and 21,000 psi after 28 days.
Anyone have experience with any of these products. I?d like to do my pour
today if possible.
Thanks in advance.
