[evlatests] Extreme Tuning in KU-band

[Rick Perley]

    Ken's latest test was to push the tuning ranges of Ku-band, using 
our super-wide 3-bit system.  The results are quite impressive ...

    He set A1/C1 to give data from 11.076 through 13.124 GHz, and B2/D2 
for 16.976 through 19.024 GHz. 

    BPASS was then run to view the spectral bandpasses.  I find:

    A)  At the low end:  Most antennas are down by 10 dB by 11.5 GHz, 
but all give usable signal down to 11.35 GHz. 

    B) At the high end:  Most antennas are down by 10 dB by 18.5 GHz, 
but all give fringes up to 18.6 GHz. 

    The problems noted in the last report are present in this test.
