Effelsberg Station report
=========================
The mk4 tape machine has been permanently
replaced by a mk5a unit. All observations to be
correlated at JIVE and Bonn are now recorded
on mk4/mk5a using disk packs. A second mk5
unit may be purchased for Effelsberg.
MPI has purchased approximately 65 disc packs 
to support both EVN and millimetre experiments.
Tape recording on the VLBA terminal is still
used for experiments sent to Socorro.

A total of 66 8-packs have been assembled with 
a total capacity of about 81 TB.

Because of the limited bandwidth of the
standard IF system (100-200 MHz) we
have  changed to 200-500MHz for 6cm and
shorter, and are building a unit to
implement the "patch" command. See:

http://www.mpifr-bonn.mpg.de/EVN/ifswreport.ps.gz

New setups and oscillator values are needed. 
For the next session incoming schedule files 
will be modified as necessary.
This new IF system also allow the mk4/5 terminal
to have the same frequency agility as
the VLBA terminal.

The subreflector replacement is now in an
advanced planning stage. This will considerably
improve performance at 1.3cm and 7mm.

A water-vapour radiometer has been developed 
and recently mounted on top of the focus cabin, see:
