WE saw this recently here, The FCC and FAA sent a crew of about 10 perrsons to hunt down some rogue emissions that were afecting the local FAA Weather Radar. They were here for about 2 weeks.
The local radar operated in 5610, had a rx opening from 5580 to 5640. The gain of the Weather antenna was 70db and the rx thershold -110, so imagine how a stray radio would interfere! They had a field day with local wispa using non FCC DFS Aproved gear in the band! They even got some stats on Canopy gear not trigerring correctly to the radar signature! They were going to Motorola with the info gathered here Gino A.

NOT Just because they have their gain tuned such that they can't hear a reflection off a baseball in your area doesn't mean your signal won't come booming in for them :) Mostly weather radar... And - remember - its just not the news stations in your area with radars // military installations, government establishments, airports, NOAA etc... the list goes on.
