It should be ready in about 2 weeks. Power filters for the box have been received. Since the decision to locate the GBT control building in the Jansky lab addition has been made, the need for shielding workstations is not as critical. Preliminary shielding effectiveness measurements on the second floor of the new addition show that the rooms have about 75db of shielding. Further tests of the 1500MHz oscillator for the laser ranging system have been completed.
Some leakage still exists.
A separate memo, documenting the tests, has been written.
