Personnel Changes
-----------------
none



Brief Report of Last EVN Session
--------------------------------
Problems occured with the 5cm receiver. Either the system temperature
and the calibration signal showed a large variation with frequency.
Especially at 6.65GHz, the system temperature was very high (500K).
A major revision of the receiver will take place in the near future.

The other parts went smoothly.


Problems Encountered Since Last TOG Meeting
-------------------------------------------
Sometime the VLBA-FS-computer (a VX Works system) crashes without obvious
reason. An upgrade should take place soon.



Changes/Upgrades Made to Hardware/Software
------------------------------------------

o Current FS version: 9.4.13.
o Telescope: The wear of the azimuth-gears still require a limitation of
  the azimuth slewing rate to 20deg/min. New gears are ordered and will
  delivered until fall 2001.
