About a month ago a spreaker radio station started broadcasting ciphered messages. Up to now we have received 19, and all have been deciphered. They warn of impending terrorism, violence on a huge scale perpetrated by cults who believe that the end of the world is near. But they also say that we can stop it, if we amass knowledge and investigate.

What we know so far: https://docs.google.com/document/d/1zar-trb6lPSBuqA-gihynMpRskavFES5iymfzMAWpvU/edit

Now dumping deciphered transmissions.
