[evlatests] RFI in X-band

[Rick Perley]

     I'm reducing some D-configuration X-band data, taken last November.

     There is a curious RFI signal seen between ~9320 and 9380 MHz.  
It's very erratic (meaning, short time-scale), and quite broad-band.  
Also quite strong.

     Any idea of where it's coming from?  All antennas seem equally 
affected, suggesting a distant origin.  But, given the data is from D 
configuration, this is a weak suggestion.
