[evlatests] New, strong, L-band RFI

[Rick Perley]

    A 'spectral sweep', with 125 kHz resolution, was done Friday, and L, 
S, C, and X bands. 

    A quick perusal of the L-band data shows a new RFI birdie, never 
seen before (to my knowledge):

    1444.50 MHz.  This is seen on *all* baselines except those connected 
to antenna 1 -- which was at the end of the west arm at the time.  All 
others are in D configuration.  The birdie is well resolved (a few MHz 
wide), and is *very* strong.   The fact that is is not seen on ea01, and 
is seen on all others, strongly suggests a local origin. 

    One other observation:  The well-known 1408 MHz birdie is on many 
baselines, but is *especially* strong on those connected to ea13.
