[evlatests] An interesting birdie in Ka-band on ea06

[Rick Perley]

    Upon continuing review:

    ea06 in RCP only has an interesting family of birdies:

    1) The line is centered at 26277 MHz. 
    2) There is a series of sidebirdies at an interval of 812 kHz, 
descending in strength, which covers essentially the entire 128-MHz-wide 
subband.
    3) This was visible, with identical characteristics, last March. 
    4) The birdie is well resolved, and moves in time -- by at last 125 
kHz over the one minute we spent at this frequency.
