Maybe the better solution is a bit more neighborly. Get a group of hams together to definitively find the source of the interference and go talk with those who are responsible and be nice about it. Also just because there is a big tower in the same area as the interference does not mean the tower is the source. Correlation does not equal causation. Some other things to consider..... is this broadband noise you describe a constant carrier or does it rise and fall possibly with another source or sources on another frequency or frequencies (which ones)? Where specifically does the interference come from? Can and have you triangulated and tracked it down definitely to its source of origin and can you prove the geographic source location with hard data down to a radius of oh at least a couple hundred feet or so? Most of the people I know that work with radio and communications systems are pretty conscientious about keeping their systems in good working order and fixing things (like interference) when they know they have a problem. Could it be that no one has alerted the proper responsible parties in a polite and helpful way with hard data to back it up and document the issue as to time, place, and characteristics as documented above? Also note that if the source *is* found to be something related to emcomm systems they generally have another reason to be nice, helpful, and responsive to hams. We tend to be their backup when all hell breaks loose. So go get a group of friends together and organize a t-hunt. Once you can define exactly where, when, (and how) the interference occurs, make some polite and inquisitive calls to find the parties responsible and offer to help resolve the issue however you can. The relationships you build through this process will likely be long lasting and have the potential to pay dividends over the long term for the entire amateur community.

I just read WB4APR message on Solar device HF noise and Han's concurrence. There is an ever growing problem of noise intrusion on many bands that the FCC does not appear to care about. Even if we do all the leg work, RDF'ing the source, and 'giving' the data to the FCC they do nothing.
Now here is where Big-Brother ARRL should stand up and create an open online reporting DB for HAMs to list the specifics of reoccurring HAM Band Noise, but not. After X number of concurrence ARRL legal could give the data to FCC WDC and hope for a resolution.
I've been consulting in the Cleveland area for a over a year during my daily commute my SUV FTM-400 scan stops on any of the FM SAT birds for a 1/4mile either side of the I-271 & I-480/Hwy-422 intersection. It is a solid +S40 FM white noise blanking a wide area of 2meters. Just to the west of this intersection on the hill is a big commercial comm tower on the University Hospitals Home Care Services building too. For the FCC this is easy citation money - if they would ever patrol large city's again.
