Indeed that is the problem.

Does error caused by the non-linearity exceed the beamwidth of your antenna?

Hi there,
Has anyone modified the LVB Tracker software to allow for more
calibration
points? If so, would you be willing to share this?
The reason I ask is that I'm using an old Yaesu G-450XL to rotate my satellite beams. I was hoping to use a FoxDelta ST2 to control this
rotator
but found that the feedback voltage is anything but linear. It seems
that
the FoxDelta controller uses the LVB Tracker version 0.7 firmware. I
took a
quick peek at the source code and it doesn't look to be too hard to
add
calibration points for say every 30 degrees. Perhaps one every 90
degrees
would be sufficient. Of course that depends also a little on the fact
if
the modified code will fit in the 16F876.
