The office I work in has virtually no radio reception because it's a former gov't facility that did highly classified work. In essence, it's a huge Faraday cage.
When I started, I was told that it was perfectly fine to stream audio over the net.
Well, today the stations that I stream are all blocked out -- Yahoo Launchcast and WMZQ, a country station in the DC area.
But, I can still stream local news radio, the classical station, and believe it or not, Don and Mike, a rather coarse radio show.
What a pain in the ass.
