STATION_NOTES
-------------
TSUKUB32(T-Ts): The X-band noise was large, 
                because the X-LNA cryogenic system was in bad condition.
               
WETTZELL(V-Wz): OK.
                Transfer rate: 200 Mbit/s

WETTZELL data were transferred to Tsukuba by 
data transfer protocol "Tsunami".
