[evlatests] A remarkable relation!

[Rick Perley]

    Ken has done a preliminary setup for the 'spectral sweep', using a 
subset of 12 antennas. 

    I looked at the S-band data produced -- less than a minute in 
duration -- looking for the 128 MHz comb.  It wasn't hard to find -- the 
one I checked is at 2688 MHz (21 * 128). 

    The RFI was seen on many baselines, all of them connected to 
antennas 6, 8, and 10.  The three baselines amongst these three antennas 
had by far the strongest RFI.  These three antennas are located at N24, 
N28, and N32!  So we can be sure that the 128 MHz comb doesn't come from 
the site, or any building there.  I suspect the 128 MHz comb emanates 
from antenna 10 ...
