Onsala (Michael Lindqvist at Sat Jun 3 12:31:07 2006) Failure : RFI

Severe RFI.

Torun (K.Borkowski at Mon Jun 5 06:25:50 2006) Minor failures : RFI

No known problems apart from the RFI. (BBC Sidebands set to upper for the entire experiment; see feedback for EV015).

Westerbork (Tony Foley at Mon Jun 5 09:04:36 2006) Minor failures : RFI

Wb used in phased array mode. Very bad RFI at the start, but mostly ends about 06UT

Effelsberg (dgraham at Thu Jun 8 11:16:07 2006) Minor failures :

some RFI from 11 - 12UT

Noto (P. Cassaro at Fri Jun 16 22:44:19 2006) Minor failures : RFI

Torun (Kaz Borkowski at Mon Jun 5 12:32:29 2006) Minor failures :

This note concerns the UHF experiments only. Shortly before the first experiment we could manage to install the Lange coupler to produce two circular polarizations instead of the linear polarization announced in the block schedule. Also, we failed to install the phase cal.

Jodrell_Bank (Alastair Gunn at Tue Jun 20 09:14:12 2006) Success : PCAL

The MkII telescope was used (Jb2). During this session the Mk2 phase cal. signal was found to be too high and could not be easily reduced in strength. I therefore switched off the phas cal. signal for the entire session (for Mk2 only).
