L band system improvements 1. 7mm. D. Wood has a collection of efficiencies measure on Jupiter on Feb 1 and 19, for which he is getting quite consistent results. Cal levels were remeasured on February 15.
Efficiencies cover about a range of a factor of two.
There appears to be serious inconsistency on antennas 12 and 25. K. Sowinski believes there is still a problem with the cal levels on antenna 4, because the two IFs give different efficiencies. D. Wood reported on his observation, which occurred during a rain. In his observations, L. Rodriguez sees a large variety of phase behaviors. Sometimes you see short term variations with an rms approaching a radian, sometimes the short term is quite good, and you see long term phase bobbles of a radian on perhaps a half hour timescale.
