It started on the night of March 3, 2019. Five of us — radio operators from different cities across Latin America — were monitoring the shortwave bands independently, as we did every night. None of us knew each other at the time.
At exactly 3:33 AM, all five of us picked up the same signal simultaneously. We know this because we later compared our recordings and the timestamps matched to the second.
The signal was on 6.666 MHz. A frequency that, according to every official registry, is unassigned and should be completely silent.
Spectrum analyzer capture — 6.666 MHz. Bogotá, Colombia. 03:33:00 AM.
The transmission lasted exactly 3 minutes and 33 seconds. It consisted of a voice — flat, without intonation, without breathing pauses — reading a series of numbers and coordinates. The voice was neither male nor female. It sounded like a human voice that had been processed to remove all traces of humanity.
"It wasn't a numbers station. I've heard numbers stations. This was different. This felt like it was meant to be heard. Like it was waiting for someone to be listening."
We decoded the coordinates independently. All five of us got the same result: a location in the Andean highlands, approximately 80 kilometers from the nearest populated area. The coordinates pointed to a specific point on a mountain that, according to satellite maps, had no structures, no roads, no reason to exist as a destination.
Three of us decided to go. Myself, a man who went by the handle "Omega_73" from Argentina, and a woman who called herself "Señal_Perdida" from Chile. We agreed to meet at the nearest town and travel together.
We arrived at the coordinates on March 15, 2019. The location was a flat area of rock at approximately 3,800 meters altitude. There was nothing there. No structures, no signs of human activity, nothing.
Except for a circle of stones. Approximately four meters in diameter. The stones had been arranged recently — the soil around them was still disturbed. In the center of the circle, buried under a flat rock, we found a metal box.
Señal_Perdida and I returned separately. During the descent, we both experienced the same phenomenon independently: our radios, which had been turned off and stored in our backpacks, began transmitting on their own.
The transmission was the same signal we had heard on March 3. The same voice. The same flat, inhuman tone.
But this time, instead of coordinates, it was reading names.
Our names.
"I destroyed my radio that night. I bought a new one six months later. On the first night I turned it on, at exactly 3:33 AM, the signal was there again."
The transmission has occurred every year since 2019, always on March 3, always at 3:33 AM, always on 6.666 MHz. I have documented all of them.
Each year, the voice reads a new list of names.
Each year, my name is on the list.
This year, for the first time, there was a second name after mine.
I don't know whose name it is. I've been trying to find out for three months.
Last week, someone with that name contacted me. They said they had been hearing a signal on their radio. They wanted to know what it meant.
I didn't know how to answer.
