[evlatests] ea13 is radiating at L-band!

    The latest 'spectra sweep' shows clear evidence that ea13 is 
seriously polluting our spectrum at L-band.  In trolling through the 
spectra provided from the data, some baselines common to ea13 show 
strong RFI at multiples of 25 MHz, extending from ~1200 MHz through 
~1500 MHz.  There are only a few baselines on which this comb is easily 
visible -- these are 13 with 9, 14, 24, 25, and 26.  All of these are 
antennas adjacent to 13! 
    It's quite clear from this that ea13 is probably the sole source of 
the interference.
