Interesting...
I wasn't able to get much sleep last night, so I decided to mess around with the spectrum analyzer. I'm borrowing a friend's RF module that covers everything from 100MHz to 18GHz to take RF noise measurements of wifi routers I quite literally hacked the living hell out of.
So I'm scanning between 1.5GHz-4.0GHz and I see an enormous spike centered at 2.2GHz that was nearly 100MHz wide (a TV station takes up about 5MHz of bandwidth, which is generally considered quite large). A quick look at the FCC spectrum database says that space is reserved for DoD. I checked it a few hours later and it had disappeared.
Looks like someone is doing some serious late night data exchanges. I also found RADAR near 1.2GHz with a period of 11 seconds, which is also DoD.
