[Ncep.nhc.nco_contacts] NHC's GOES-W antenna movement

So do we want to put the item on hold until we get the IDU back and can verify full antenna movement in azimuth and elevation? It sounds like the elevation timeout change to 4 seconds may have fixed the issue, but I would like to fully exercise the antenna to formally call the issue closed.

Thanks,
Greg

> Open the ODU (EL), viewing the EL ACU card, when giving the jog EL up command, see if the (6th LED from bottom) illuminates, also look at the EL VFD, the display should change to a frequency value. The EL Down command will illuminate the (5th LED). IF the LED’s and VFD are changing status. See if you can see if the motor shaft is rotating. You may  need  to put a mark or tape on the shaft to see it move.

I didn't see any other error messages. We had no trouble changing the Azimuth on GOES-West, or the Elevation and Azimuth on the other two antennas.
