  1. Current Issues
    Replacement STS-2 has either failed or the local operator had issues with the install. The TR240 has been moved to the primary channels (00 location code) until the problem can be resolved.
  2. 2012-08-12
    Since Aug. 12 (2012) timing quality has been bad. A replacement GPS antenna was installed 12 Sept 2014.
  3. 2011-11-05
    Power system repaired and data flow has resumed.
  4. 2011-06-11
    Data flow stopped due to power system failure.
  5. 2011-05-25
    Upgraded to Q330 digitizer.
