Station report for Effelsberg   (Jun 2005)
=============================


- Most observations during the last session went smoothly (despite some
  problems with the formatter, which could be replaced quickly by the EVN spare
  formatter - thanks to the Medicina team for providing prompt help). Again,
  the majority of experiments ran on the MK4/MK5-terminal.
  However, between the sessions, we participate regularly on 
  VLBA+EB (including HSA) observations; these run on the 
  VLBA-terminal. Additionally, in April, Effelsberg observed within
  the Global mm VLBI Network (using MK4/MK5).

- Dave Graham constructed an IF switchbox which was implemented before
  the June session and used throughout without problems. For details see
  http://www.mpifr-bonn.mpg.de/EVN/ifsw.html.

- The project 'new subreflector' for the 100m-telescope is progressing
  es expected. The design phase is coming to an end, construction
  should start soon. The new secondary mirror with active surface,
  improved focus drive, and better frequency agility to be 
  installed in summer 2006.

- The water-vapour radiometer, mounted on prime-focus cabin, is in
  frequent operation. A web-based interface to the data on a SQL
  server is under development.

- The geodetic GPS receiver is in continuous operation. The data
  is available on request.

- The generic VLBI account for Effelsberg (evlbi@mpifr-bonn.mpg.de) 
  will soon be closed. Please address all requests directly either
  to Axel Jessner (ajessner@mpifr-bonn.mpg.de) or Alex Kraus
  (akraus@...).
