Vina del Mar Relay Station transmits a steady stream of numbers read by a calm female voice every night. This code is required by our scientists to recalibrate some of the more exalted experiments. Yesterday a second signal started to overlay the quiet announcements. At first it was a low intermittent crackle that our experts in Santiago mistook for atmospherics. Minutes late the crackle had risen and changed to include higher harmonics, a strange scintillating composition taking over the airwaves. At seven minutes into the transmission the unknown signal had become so strong that it was hard to even discern the voice of the reader. It was then that our experts noticed a detail with the most frightening implications: the girl had begun changing her rhythm ever so slightly to better match the signal – with no speakers installed in the recording room. Later no code could be heard at all, and only once or twice a high pitched scream came through the fiendish interference.
