Everybody in radio should have one of these. They're called RadioSharks, and it's akin to a TiVo for radio. But the real application is that you simply install the provided software, plug the Shark into a USB port on your computer, and up pops a radio dial. You “tune in” the station of your choice, adjust the Shark (built-in antenna), and start recording whatever you like directly onto your hard drive. You can then listen to whatever you “taped” late or burn it to a CD.
There's also a timer, so if there's something you want to capture, the Shark will take care of it while you're doing something else. I have purchased Sharks for my staff (roughly $60-$65 at Amazon, J&R MusicWorld, etc.). Now when we make market visits, we can “tape” other jocks we might be considering, or stations that we think you'd be interested in hearing.
Why didn't I think of this?
