[evlatests] Phase Switching is part of it ...

[Rick Perley]

    Ken turned off phase switching, with the result that the 'pulsing' 
behavior has gone away, and the gigantic closure errors are back to more 
normal (5 to 10%) values. 

    He left 26 in a phase switching state -- to test me.  I was equal to 
the challenge1  :)  It is still 'pulsing'. 

    We note that the last time we know we had good data was immediately 
prior to maintenance day, last Thursday. 

    I still see the EVLA being significantly less sensitive than the 
VLA.  Larry B. assures me the feed heaters are on now (it's been snowing 
up at the site for the past couple of hours) for both VLA and EVLA.
