Station Summary

Early reports of E05 can be traced to the 1970’s. E05 was one of the English language stations maintained by the CIA’s network, thus E05 earning the nickname “CynthIA”. The voice employed was very professional in its work, having an obvious American accent.

Transmission schedules at E05’s height transmitted every day, in USB mode and a very strong signal sometimes more powerful than the AM broadcasts around it. At the end of E05’s existence over 100 regular frequencies were logged for it, being relayed from various countries allied with the US. When transmissions began a distinctive background noise was heard behind the voice machine due to high traffic. The noise itself could be described as the sound of rushing air.

Another form of this station was identified as E14. E14 is a ‘control’ station, only sending call ups with no messages; possibly as a way to distract jamming efforts. E05 was another station that had issues with being the victim of intense jamming attempts. The jammers would appear at either side of the transmission making it impossible to copy. Sometimes the call up would send clearly, only to be drowned out once the message arrived. On longer transmission the jammers would sometimes go off, its operators making sure E05 was still there before resuming. These became less frequent in the mid 1990’s and E05 had a mostly clear broadcast for the remainder of its life.

Message Sample (not callup):

Family Relatives: G05, V05, E14, E21(#), V14 (# May not actually be part of the network)
Station Family: Family 2 “CIA/NSA”
