Perhaps you've chanced upon a Number Station, unwittingly as you scour the shortwave bands, and heard a cold, disconnected voice repeating simple commands endlessly into the ether. Or maybe you've scanned past a series of bleeps and pips, or pockets of noise, thinking nothing of them, as you seek a favoured music station. These are messages, to those who know how to receive them, and are able decode them in their various forms and configurations.

Shropshire Number Stations - Recordings of Covert Shortwave Radio Stations charts the covert shortwave radio stations broadcasting silently through the air around us, to aspirant agents in the fields of Shropshire, UK and the counties which surround it. These two continuous sides include recordings of 19 such lay-stations, captured by Eric Loveland Heath at various points over the last few years. The true nature of these amateur networks may never be known, nor might their cyphers ever be revealed. These are recordings of their activities, made conceivably for the sake of posterity alone, offering a glimpse into clandestine worlds otherwise obscured from view.
