Weather was mostly overcast through out the observations with a few gaps of clear sky. At 9:13 UT we’ve changed the DDC firmware on the DBBC2. The performance of V107 in geo-mode did not look as good as it should be and indeed the change to V016 improved Tsys in IFB and IFC. There was likely some contribution of artificial noise from the DBBC in some channels during the first part using V107 (reduced SNR?). As far as I could see there was no clock jump when changing firmware. gps-fmout looked reasonable stable over the observing time. Missed the following scans due to unintended antenna stops: 2019.324.10:51 1749+096 missed 2019.324.10:54 3c418 missed 2019.324.12:07 1749+096 missed The data will be e-transferred to Bonn.
