[evlatests] L-band frequencies

[Rick Perley]

    The L-band data taken yesterday allows a check on frequency 
headers.  All looks correct, to an accuracy of ~100 kHz or so (presuming 
the actual frequencies of our 'signposts' are what we think they are ...):

    I see two continuous emissions, centered at:

    1246.0, and 1268.5 MHz.  The former is quite strong, the latter is 
very narrow and continuous.  Dan:  What are these? 

    The usual ABQ radars are seen.  There are four, two of which seem to 
be much narrower in frequency that the others: 

    1310.0 and 1330.0 MHz.
