I doubt that the Utah Data Center is a "front end" for receiving electromagnetic radio signals. Reception of those signals would be in remote locations and sent via fiber optical links to the data center to be stored and processed. NSA data centers do not need to be as free from radio interference as radio astronomy reception locations.An engineer formerly working at the National Radio Astronomy Observatory (http://www.gb.nrao.edu/nrqz/) lists its radiation emissions controls: http://cryptome.org/2013/07/radiated-emissions-control.htm Among them is the banning of vehicles which use spark plugs, thus diesel-fueled are required. Which suggests a question about radiation emissions at NSA Utah Data Center's 32 large generators. Since nearly all government and commercial data centers have generator back-ups, how are emissions from generators controlled? NRAO also "banned digital cameras down range after they proved quite noisy." Are noisy digital camera emissions more privacy threatening than phone signals? Is NSA harvesting those emissions?
There are hardware hacks to pick up computer keyboard signal emanations. Does anyone the the Maker/Hacker community have a similar hack to pick out digital camera signal output? Probably would be much easier to hack into the picture as it is transmitted/transferred by cellphone radio than to capture it from stray emanations in the actual process of taking photos.
Given the amount of noise on almost all available radio bandwidth the 'spark plug' problem should be mostly insignificant when compared to other sources.
