[Antennas] my beam moves itself!

[Billy Cox]

Gary,

Does the indicator follow the beam OK?

<If so, then your clamps are probably OK>

Can you have someone operate the control box
while you are outside to where you can HEAR
the brake wedge being released? <it's normally
a 'klunk' sound> You should be able to hear it.

Check for that ... as it seems like the wedge is
NOT engaged, and the beam is free floating.  Or
the lower casing is not locking down on the wedge.

The Ham-II had a upgrade ... better wedge and 
lower casing ... seems I upgraded one of mine
several years ago.

Hope this helps ...

Subject: [Antennas] my beam moves itself!

i have a problem with my CDE Ham II rotator (purchased used about three 
years ago). it goes like this:

a couple of weeks ago, i noticed that my beam seemed to be moving itself. i 
figured i could check whether the control box was at fault by simply 
unplugging the unit from the electrical outlet.

so the next day, i plugged in the unit, pointed the beam due north for a 
sked, then turned off the control box and unplugged it.

a few hours later, i went outside and looked and the beam had turned itself 
180 degrees and now pointed due south. i repeated this experiment just in 
case i had had something wrong the first time. but, indeed, without power, 
the beam moves itself to due south.

i doubt that the clamps are loose: when i move it back to north, movement is 
same as always and it's not a problem.

i'd be grateful for ideas from anyone about what to do (i know, i know...get 
a new one and use this to anchor a boat somewhere...)...if there's 
reasonable fix, i'd prefer that.

thanks much,
73s,
