Subject: change at EBRE site

As anounced last Friday, the GPS receiver and antenna have been changed
today DOY: 105 at 10:00 UT. Data will be available from 00:00 to 10:00
UT recorded by the old receiver-antenna and from 11:00 to 23:59 UT
recorded by the new receiver-antenna.
Following there is the updated logsheet with the changes made. Note that
the antenna mount has been removed, so now the antenna height is 0.0
meters (it is mounted directly to the monument reference point).
