12:35 UT Good news! The 27-m receiver is back. When installed, it seemed to have a problem still with the Hi H polarization (0 drain current), but this morning the drain current is back... Mark says he will try replacing the Bias board today, but in the meantime, I am taking data on 2136+006, with pcal_hi-all.fsq, with the 200 MHz correlator. I hope to be able to set the delays as soon as the first data are available (the first scan started 12:34 UT). Note that I also updated the FEM and DCM attenuation settings this morning, so everything should be more or less operational.
