[evlatests] Antenna 14

[Rick Perley]

    First -- the good news.  There is no sign of the 'wandering phase' 
that EVLA antenna 14 used to show. 

    But, from last night's test, I find that IFs B and D gave no 
fringes, at P and L bands only.  At all other bands, all four IFs 
behaved relatively well.   

There is a regular amplitude modulation on IF 'A' -- typically a few 
percent in ampliutude and a few tens of seconds in period, seen at L, C 
and (weakly) at Xband.  No correlation with reported Tsys is seen.
