[amsat-bb] Help with SatPC32 Labjack Yaesu 5500 rotator control

[Alan]

Quick progress report.

After deleting KB4103718 and resetting the rotor position change to 3
degrees, I have not seen a stall in a week.  I will open that out a degree
at a time, and see what if anything happens.

73,

<Erich,
<
<So far the stalls have occurred in the middle of the night.  One was
showing
<the elevation at 4 degrees, with the target at 0.  The Labjack server was
<indicating a down command.  I closed and restarted SatPC32 and when I
<selected Park, it dropped to 0 and the desired azimuth.  The second time
was
<an azimuth problem, with a large difference between the commanded and
<actual position.  The Labjack server was indicating a turn.  Closing and
<restarting cleared the problem.
<
<There are two changes that I know of.  I recently changed the rotor
position
<change window from 3 degrees to 10 degree to reduce wear, as that is close
<enough for LEOs.  I have reset that to 3 degrees to remove the variable.
<
<Mark, G0MGX suggested that I look at KB4103718, which has been reported to
<be causing some USB issues.  I have removed it, and will see what happens.
If
<it happens again, I will get more details.  It certainly looks like
something in the
<OS rather than SatPC32.

<<Hello Alan, Nick and others,
<<I didn't make any changes with  ServerLabjack. The file is unchanged
<<since Dec. 12. 2012.  SatPC32 itself only outputs the target positions
<<to ServerLabjack. Only this file then checks whether the rotors have
<<reached the target positions.
<<Is there any  correlation between updating  the target positions by
<<SatPC32 and stalling of the rotor?
<<
<<I also use  Windows 7, 64-bit and  the Labjack U-12 with a KR-5600.
<<Lately I used it for multiple satellite passes and  I just tested full
<<360° turns of the az. rotor/ 90° turns of the el. rotor in both
<<direction (entered target postions in menu "Rotor").   No issues so far.
<<73s, Erich, DK1TB
