For your listening pleasure: 32 minutes of pirate radio station, WMPR.
I recorded this broadcast of WMPR on 6.925MHz AM on February 17th, 2013 at 10:00 UTC. You'll note that this recording sounds a little "brighter" than a typical shortwave radio recording. This is due to the fact that I widened the AM filter to match the bandwidth of WMPR's signal (about 17 kHz!).
