This probably happens when a command is sent to 2k to track an object. For some reason, the antenna does not ever reach the target.
Could be tested with a program that monitors 2k position (in background) while randomly setting the antenna to track a target one after the
other. Hopefully could diagnose the reason why 2k does not reach source.
2k is entirely offline after installing new switches. 2h is also now offline completely. Will look into both of these.
