I think people in San Diego and near Norfolk, VA have the same problems.

The C-band frequencies are 2x those of the S-band (4-8 GHz for C, 2-4
GHz for S); if the SPY-1 / SPY-1D radar is frequency hopping it may
well step on someone's C-band links at twice the radar's basic
frequency.  Just need a filter to remove actual S-band frequencies
from C-band feeds.
