[evlatests] 4-band Status

[Rick Perley]

    Things are much improved now.  Ken squashed some buglets, and the 
observations just made clearly show the following:

    1) Antennas 7 and 12 give no fringes at all. 

    2) Antenna 24 is completely messed up -- huge and false amplitudes, 
or noise, or both. 

    3) Antennas 11, 17, and 26 have their polarizations reversed.  
Please interchange the R and L cables. 

    4) Antenna 18 gives barely visible fringes. 

    5) Antenna 21 gives no fringes on the A,C (IF#1) side. 

    6) The fringe amplitudes for antennas 11 and 19 are very low.
