It is not quite clear what caused the receiver to stop tracking about a week ago. It had been observed for several months already that the performance was not optimal. During certain periods of each day the receiver looses lock on most low elevation satellites. It is hypotesized that this may be caused by interference due to a nearby radar site located about one kilometer away from the station. We suspect that this may also be the cause for the complete breakdown of the receiver during last week. We are considering to replace the antenna by a new interference hardened version, in the hope that this may cure the problems. Further announcements will follow as the situation develops.
