I recently became aware of this talkshow on radioevolution called Starfleet Communicator.

Broadcast every Thursday night at 6:00 P.M. EST | 7:00 P.M. MST | 8:00 P.M. CST | 9:00 P.M. EST. They are a new show - I think this is episode II, but older shows are available to listen to as well.

Stop by, kill some time, and even phone in.
