Hard core WFMU Listeners are probably familiar with The Conet Project, a four CD set of shortwave recordings of "Numbers Stations." Now the entire set can be downloaded directly from Irdial, here.

A typical numbers station will repeat an endless series of numbers, only a tiny portion of which actually carry any meaning. It's the needle-in-a-haystack approach to secure encryption.
