Station report for Effelsberg   (Nov 2004)
=============================


- Most observations during the last sessions went smoothly. After switching
  to MK5-only, the majority of experiments ran on the MK4/MK5-terminal.
  Between the sessions, many experiments took place on the MK4- (eg. for 
  the Global mm VLBI Array), and the VLBA-terminal (VLBA+EB, High Sensitivity
  Array).

- The water vapour radiometer for providing auxiliary phase and delay
  measurements for VLBI has been installed at the telescope site. First
  tests (during the 3mm GMVA observations) show encouraging results.

- The project 'new subreflector' for the 100m-telescope has just started.
  We expect the new secondary mirror with an active surface (with higher 
  accuracy), improved focus drive, and better frequency agility to be 
  installed in summer 2006.

- A new 21cm-system with better performance is currently under construction.

- The 50cm-receiver is currently not available.

- Axel Jessner (jessner@mpifr-bonn.mpg.de) joined the VLBI team in Effelsberg
  and will share responsibilities with Alex Kraus.
