STATION_NOTES
-------------
TSUKUB32(T-Ts): OK.  
               
WETTZELL(V-Wz): Low amplitude in SR4U caused a D code on scan 087/07:53.
                Manual pcal in fringe fitting.
                Transfer rate: 256 Mbit/s

WETTZELL data were real-time transferred to Tsukuba by 
data transfer software "VDIF/SUDP".
