The Frequency That Doesn't Exist — 7.047 MHz and the Voice That Shouldn't Be There

23:14 local time. August 3rd, 2026.

I was running my usual sweep of the 40-meter band when the waterfall display lit up with something that made me double-check my equipment. A strong, clear signal at 7.047 MHz — right in the middle of a frequency allocation that's supposed to be unused in this part of the world.

Not static. Not interference. A voice.

## THE TRANSMISSION

Male voice, measured cadence, reading what sounded like coordinates. I grabbed my headphones and started recording.

The audio quality was better than it should've been for shortwave at this distance — wherever it was coming from. No fading. No atmospheric distortion. Just clean, precise speech reading strings of numbers:

"47-23-17... 82-11-09... 34-47-03..."

I checked my logs. The signal repeated exactly every 17 minutes. Same voice. Same number sequences. Four complete cycles over 68 minutes.

Then at 00:22, it stopped mid-transmission. Not faded out — just cut, like someone flipped a switch.

## WHAT I KNOW

7.047 MHz falls in a frequency range that's allocated to amateur radio in some regions, but not consistently worldwide. It's also close to — but not exactly on — frequencies used by military and time signal stations.

The coordinates don't map to anything obvious. I've been plotting them for the past eight hours. They're scattered across the eastern United States, no clear pattern. Some are in national forests. One is in the middle of Lake Michigan. Three are within 50 miles of military installations.

The 17-minute interval. Always 17.

I've been tracking this for 7 years now, and that number keeps appearing in ways that make pattern-recognition software in my brain light up like a Christmas tree. But I also know what confirmation bias looks like.

## THE ALTERNATIVES

Here's what it could be:

• **A numbers station.** Intelligence agencies have been using shortwave to transmit encrypted messages since the Cold War. They're still active. This fits the profile perfectly — coded coordinates, precise timing, sudden cutoff.
• **Military exercise.** MARS (Military Auxiliary Radio System) operators sometimes run drills on frequencies that overlap amateur allocations. The clean signal quality suggests professional equipment.
• **Pirate broadcaster.** Someone with good gear and a weird sense of humor, deliberately choosing a frequency and timing pattern to mess with people like me.

All of these are more likely than what my gut keeps suggesting.

## WHAT DOESN'T FIT

But here's the thing — I've monitored this frequency range for three years. I have automated logging running 24/7 with alerts for unusual activity. This signal appeared with no preamble, no testing, no preliminary transmissions. Just suddenly there, as if it had always been broadcasting and I'd only just tuned in.

The coordinates themselves: When I plot them on a map and connect them in sequence, they form a rough arc. Not a circle. Not random scatter. An *arc* that curves from Tennessee northeast toward Lake Ontario, then abruptly terminates.

The same arc I've been tracking aerial returns along for the past four months.

Coincidence has a pattern if you look long enough.

## TONIGHT

I'm keeping the SDR locked on 7.047 MHz. Recording continuously. If it comes back at the 17-minute mark, I'll have more data. If it doesn't — well, that's data too.

The numbers don't lie, but they don't always tell the whole truth either.

Has anyone else picked up transmissions on 7.047 MHz in the past 24 hours? And if you plot coordinates 47-23-17 / 82-11-09 / 34-47-03 — do they mean anything to you?

Another entry for the log.

Stay vigilant.
