The isolation of the numbers station’s location worked decently. The broadcast range of the numbers station covered a manageable area that chiefly encompasses Wisconsin, Illinois, Indiana Michigan.
Close to the eastern coast of Lake Michigan, a weak reception can be picked up in western Michigan and north-western Indiana. The strongest reception is present in south-eastern Wisconsin and north-eastern Illinois, also in the proximity to the coast.
They actually managed to reproduce the transmission cut-off event, the exactly the same event when they first communicated their encryption key: after they sent the key and it was time for the station to air, the introductory part was interrupted halfway through and the other transmission spliced in, exhibiting an identical pattern as earlier. Furthermore, transmitting anything on USB or LSB did not make a noticeable difference, however.
For the associates that were tasked to help with the triangulation, the situation took a slightly different turn. From the associates’ perspective, it appeared like the station succumbed to a sudden power failure and ceased to air. Complete silence prevailed for precisely 120 seconds before the station resumed its normal operation. These 120 seconds were briefly interrupted by two bursts that were separated by a time gap of 75 seconds. The bursts appear to be a sped up Morse-encoded message:
“AYIN LETZIYON TZOFIYAH”
Beyond that, there were no other notable frequencies or anomalies.
The analysis of the audio sample was tougher nut to crack, but it maybe it was worth the money. Someone applied a steganographic technique to discretely encode information in the beat of the music itself. It was a hidden Morse code message:
“THE BELL TOLLS FOR THEE. DC7941E387159BE7.ONION”
Apparently it contained a deep web link that lead to a plain text page. The text was encrypted with the the PGP they sent previously and was signed by key ID 45 6C 73 65, the same one as mentioned in the first-contact message.
Decrypting the text yields a list of people:
People had tried to solve the murders, but their investigation has hit a dead end. Contact them.
Erica Larsson - picked up the trail.
ew Ze%27ev Gudavich - effectively the lead investigator. He followed the trail and was driving force behind the investigation. Investigations stalled significantly when he had gone missing. Maybe find his notes in his home or at last known location?
Trevor Arnell - seen with
Ze%27ev Gudavich, possible associate.
Joseline Tenjo - helped acquiring clues.
Vance Reid - Barkeep of Saevae, had contact with the group of investigators. Should be also be able to rally up more people.
I will see if I can recruit more. Stay tuned.

((There were probably more people in the investigations, but I dunno.))
