Frequency 88.7 was dead for six weeks. It came back on January 10th at approximately 0340 hours. The transmission was captured on a portable receiver near the south end of Monk.
The message is short. Less than ninety seconds. It loops on a 17-minute cycle. The content is fragmentary and partially degraded: what sounds like a room number, a street name that does not resolve cleanly on available maps, and a sequence of numbers whose purpose is not established. No voice. The audio is synthesized or recorded.
There is no carrier signature consistent with a civilian emergency band. The equipment producing this signal is either improvised or repurposed from something older.
Three interpretations were logged at the time of capture:
Automated remnant. A pre-set broadcast from equipment still running on backup power. This is the most common type of dead signal. It does not indicate a live operator.
Active signal. Someone is using old equipment deliberately and knows how to loop a message. This would indicate a live operator, but not necessarily a cooperative one.
Bait. A loop designed to draw attention to a location. This possibility has not been ruled out and should not be.
The signal was last confirmed active at 0210 hours on January 12th. It has not been confirmed since. Either the power source failed, the operator went silent, or the equipment was moved.
No team has been sent to locate the source. The Monk Residential block is navigable but carries medium threat. Entry is possible with care. The specific origin point within the block has not been established.
Anyone moving through the Monk Residential subzone should monitor 88.7. If the signal resumes, note the time, the loop start, and any deviation from the captured fragment.
Do not respond to the signal from a fixed location.
