[evlatests] A new, bad source of wideband RFI at P-band

[Rick Perley]

In order to characterize the P-band beam when the subreflector is in the non-standard positions (for VLITE), I have taken more than a dozen short observations at P-band over the past few days.

The latest one, taken last evening near 7PM, at very low elevation (pointing to the NE) showed a strong, wideband source of RFI that I've never seen before.

It spans 338.0 through 344.0 MHz, and was on continuously through the 35-minute observation.  It was much stronger in the horizontal plane than in the vertical.

Any ideas of what this is?

Rick
