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.
