I've posted an analysis of Lab data from 08 Dec 05, calculating Trx.  It
can be found at http://wiki.gb.nrao.edu/bin/view/Projects/CcbDecTrx

The summary is Trx is between 20 K and 35 K for almost all channels (2
channels have Trx ~40 K (1 channel = port/phaseSwitchState).

Also, I've posted plots of the Light Curve following turn on and turn off
of the Cal signals at
http://wiki.gb.nrao.edu/bin/view/Projects/CcbDecCalLtCurves

There seems to be no major issue there.
