Jose - Goldstone and Freily say X up and S/X down should be possible; maybe the crew did not understand the process. Jesse will open a DR if it turns out to be a procedural problem; he will ask the crew to phone us on the meet me line. Freily - 'retracted' means X only. 'Extended' means S/X down possible with either S or X up. If 'retracted, would have X up and down, but the S is not reflected into the horn. Noise Temp in 'extended is 1.0-1.5K higher. Normal configuration is to 'retract' the dichroic plate for X-band up. So need to put dichroic plate into 'extended.' Jose says this should already be in the X-up, S/X-down configuration procedure; but it may not have been followed. S band went away during LCP noise diode measurements.
