[evlatests] Huge RFI in Ku-band

[Wes Grammer]

This looks suspiciously close in frequency to an RFI spike Dan Mertely 
discovered a few weeks back, which he traced to the Lowband receiver on 
ea19. Denis and Dan Dillon had a look at that receiver in the lab this 
week, and discovered it was the noise diode generating the RFI.

Maybe Mertely could check these antennas today or tomorrow, to see 
whether it's the same problem as on ea19?
