AGC (Automatic Gain Control) was turned off, the conditions changed so the automatic adjusting didn't compensate. Possible the gain was manually increased to be more sensitive. Also possible the expected ground clutter overlay file (buildings, hills, etc.) which is applied through digital processing and usually doesn't show is not being processed as it usually is.

They are upgrading many Nexrad radars to Dual Polarization which can see vertically as well as horizontally; I think that might be increasing feedback depending on which mode the radars are in.

What is the difference between feedback and clutter? Just curious.
