Sorry, I was not clear. Will try again. I did not mean to suggest Utah was an EM reception station but to query how NSA protected against its own apparatus emissions, sometimes overly simplified under the rubric of TEMPEST -- an ever shifting and refined technology. TEMPEST protection measures are known to be capturable and exploitable for counter-counter-spying. Not unlike encryption and anonymizers target their users. So, if NRAO is affected by its emissions and NSA has similar capabilities then it would protect against, harvest and analyze emissions similar to the way NRAO does, or more likely, much better. Harvesting the harvesters is common tradecraft as with counter-spying the counter-spies. However, the exquisite capabilities of NRAO-like antenna array are not common nor accessible to the general public -- there are at least three of these around the US and more overseas linked by super-fast scientific networks. Presumably they have lesser capabilities than those used by official spies, although mutual assistance is fairly common in educational institutions as in commerce, for the same profitable reasons, and as always, sacred cow national security. Reportedly a former NSA array was inherited by an educational institution to use out-dated equiment. The equipment still useful for NSA purposes had been removed, or so the story goes. It is hard to get information that is not deliberately leaked, redacted, fed to malleable outlets for editorial obfuscation, all this is now a major online industry amplified from the earlier analog distribution. Popularization of technical information is pretty well condemned to degradation for easy and avid public consumption. As with the latest NSA revelations, nearly all of which is recycled with dollops of "shocking" novelty, with a few documents seasoning the voluminous editorializing referring to lurid accounts yet to be revealed, or not. A congressional hearing tomorrow will feature this methodology avidly seeking eyeballs. Hopefully a few more of Snowden's documents will be released unseasoned by gravy of Greenwald's gravitas, but probably only teasing tidbits as during the past few weeks. Hang tight, books and documentaries and movies are in the works. Along with Assange's and Manning's emissions.
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.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.--All my email is subject to viewing by the Panopticon :: https://en.wikipedia.org/wiki/Panopticon :: Except in the imaginations of the netizens there is no real secrecy or privacy on the Internets.
