L20030313_00017:02:30Start of experiment0EG
Started data taking but will be adjusting convergence and
testing daystar in the path. skies not quite clear but will try
to get an indication of the receiver status.
L20030313_00017:32:45Have been tweaking and finding the beam again. running0EG
with a 20db attenuator to use singal from low altitudes.
L20030313_00017:45:06removed 20db ND filter and raised chopper0EG
there is a lot of cirrus interfering and noise levels are high
L20030313_00017:49:52Daystar put in the path1EG
L20030313_00017:54:58Getting a signal trough but clouds hamper real adjustments1EG
contiuing when it gets darker.
L20030313_00017:55:59End of experiment1EG
