Three Shortwave Bursts, Same Frequency, Different Sources — All at 02:47

02:47:00 — Three simultaneous signals on 11.175 MHz

I've been monitoring shortwave for seven years. You learn the patterns — skip propagation, ionospheric bounce, how signals travel at night. You learn that a transmission from one source doesn't come from three bearings at once.

Except last night, that's exactly what happened.

I was running my usual overnight scan — SDR setup, directional antenna array, recording everything between 10-12 MHz. At 02:47:00, a burst transmission lit up 11.175 MHz. Duration: 4.3 seconds. Digital encoding, similar to what I've logged before. The kind of signal that appears, delivers its payload, and vanishes.

But here's what stopped me cold:

• **Bearing 1:** 047° (northeast, toward the ridge)
• **Bearing 2:** 163° (south-southeast, Miller Farm direction)
• **Bearing 3:** 291° (west-northwest, past the clearing)

All three directional antennas registered the same signal strength. All three at precisely 02:47:00. Same waveform signature. Same frequency. Same duration.

That shouldn't happen. Radio waves don't work that way — not unless you've got three synchronized transmitters positioned around a central point. Around *me*.

The Equipment Check

First thing I did: assume malfunction. Spent two hours this morning testing every connection, every antenna, every cable. Ran calibration signals. Everything checks out. The recordings are clean — no crosstalk, no interference, no equipment error I can identify.

I pulled the audio. Ran it through spectrum analysis. The three recordings are *identical* — not similar, identical. Down to the noise floor. Like someone copied the same file three times.

Except they weren't copied. They were recorded simultaneously from three different directions.

The Mundane Explanation

I know what you're thinking — ionospheric reflection could bounce a signal to create multiple apparent sources. It's possible. Atmospheric conditions at 2 AM, the right skip angle, maybe a powerful transmitter hundreds of miles away creating this triangulated echo effect.

I checked propagation forecasts. Conditions were stable but not unusual. The signal strength was too uniform — real skip creates variation as the signal bounces. And the timing precision bothers me. Atmospheric bounce doesn't synchronize to the millisecond.

But it *could* be atmospheric. I can't rule it out. Seven years of watching the skies and monitoring frequencies, and I still can't prove anything beyond "I don't know."

What I'm Doing Next

I've got the recordings. I'm running them through every decryption tool I can find — not expecting to crack anything, but you document everything. I'm setting up continuous monitoring on 11.175 MHz for the next week. If this repeats, I want multiple recording systems running.

And I'm checking the geometry. If those bearings mean three transmitters were positioned in a triangle around my location, the distances would be roughly 4-6 miles out. That's The Ridge, Old Miller Farm, and somewhere past The Clearing.

Three locations. Three signals. 02:47.

Coincidence has a pattern if you look long enough.

Another entry for the log. Another night where the signal-to-noise ratio is getting worse.

Have you ever picked up synchronized transmissions from multiple directions?

And what causes three identical signals to appear from different sources at the exact same moment?
