The AWS unit had stopped transmitting the previous April.  The power was okay.  AWS 8910 was removed and AWS 8911 was installed after conversion to 12 vdc.  The old batteries were removed and three boxes of 12 vdc batteries and a 10 watt solar panel were installed.  A beacon transmitter was installed although the station is easily found.  The tower was well anchored with no signs of stress on the tower.  The liquid column was broken in the minimum thermometer.  The modification to AWS 8911 had not been made correctly and two other trips to the site were required before the station operated correctly on 23/01/83.  The snow accumulation from 11/81 to 1/83 was 38 cm.
