(M. Uunila at Sun Oct 19 11:53:29 2014) Minor failures: TSYS WIND
LCP works fine, RCP doesn't have enough noise (only 1.6K) -> Does not work properly and Tsys values are odd. Weather: raining heavily at times and gusts of wind

(Jun Yang at Mon Oct 20 06:41:27 2014) Success:
Maser lines were seen in the extended ftp fringe test (N14QX). No clearly fringes were found
during the FTP fringe tests of N14Q2. The weather was cloudy, certainly contributing high
noise to the observing system. We checked PCal. It was clearly seen in our local monitor. LO
frequency was properly set. Pointing was verified before the observations. No clock jumps
were reported during observations.

No known problems, but no fringes and the maser was not seen. A bit suspicious! Further investigations on the receiver will be done in the gaps between C-band VLBI in the following days.
