I have used the subject rotator for almost 5 years. Last March the rotator
began behaving erratically and I returned the control box to Yaesu. 6 weeks
and $100 later they returned it saying they had "realigned" it (most of my
problems were related to inaccurate manual antenna direction--see letter
extract below). And the rotator worked fine. Last week the rotator stopped
working. The control box powers up but nothing happens when I press the manual
or preset controls. I haven't been up the tower yet to check the molex
connection so it's possible that the problem could be in the control cable (or
it could be the rotator). Before I get too involved here has anyone experience
similar symptoms where nothing happens? I hope to be able to borrow a spare
control box to see if the control box is again the culprit. Following is what
I wrote to Yaesu in my March 2006 control box problem:
Here are the symptoms of my problem:
(1) On power-up, the direction indicator automatically moves
either CW or CCW up to 20-30 degrees and stops; sometimes it comes back to its
original position;
(2) In manual control, it is difficult to get the antenna to stop
on a fixed heading such as north; the antenna goes past it and I have to keep
moving it back and forth to find the heading;
(3) In the preset position, if I turn it to 90 degrees, sometimes
the antenna stops 20 to 30 degrees off that heading and I?ve now noticed that
the indicator can show 45 degrees and the antenna is actually pointing north.
Of course, nothing at all is happening now. The antennas consist of a F12 C4E
and a C3i 5 el Yagi 8 feet above it.
Thanks in advance for any help, 73 and HNY to all.
