The Frequency That Shouldn't Exist: 7 Years of a Signal That Has No Source

2347 hours. Signal detected again.

I need to document this because after seven years of monitoring, I still can't explain it — and I've tried everything.

The frequency is 11.374 MHz. Not 11.375, not 11.370. Exactly 11.374. It transmits every 47 hours (there's that number again) for exactly 17 minutes. The signal is FSK-modulated, sounds like old-school digital packet data, but doesn't match any standard protocol I can decode.

Here's what makes it strange:

• **No registered license** for this frequency in FCC databases
• **No directional source** — my directional antenna can't pinpoint origin
• **Perfect timing** — hasn't varied by more than 3 seconds in 7 years
• **No response** — I've transmitted on adjacent frequencies, no reply
• **Continues through weather** — storms, solar flares, nothing stops it

I've logged 1,347 transmissions. I have recordings. I've run them through every decryption tool available to a civilian. Nothing.

Tonight I tried something different. I set up three receivers at different locations: one here at the house, one at The Ridge (2.3 miles north), one at the creek bed (1.8 miles southeast). I wanted to triangulate.

Results: All three receivers picked up identical signal strength. That's not how radio propagation works. A ground-based transmitter would show distance-based attenuation. A satellite would show doppler shift. This showed neither.

The mundane explanation? I've considered it extensively:

• **Military black project**: Possible. The frequency is in a ham band, but military sometimes uses civilian frequencies for testing. The timing could be automated satellite telemetry.
• **Equipment artifact**: My receivers could all be picking up harmonic interference from a distant broadcast station. 11.374 could be a mathematical artifact of mixing frequencies.
• **Ionospheric ducting**: Under specific atmospheric conditions, a distant legal station could appear sourceless due to skip propagation.

I even contacted a radio engineer friend (former colleague, one of three who still talks to me). He suggested it could be a numbers station — encrypted spy communications. Those do exist. They do operate on odd schedules.

But here's what keeps me watching: The signal started exactly 17 days after the first Dead Zone appeared at Old Miller Farm.

Coincidence has a pattern if you look long enough.

I've been tracking this for 7 years now. Not once have I captured definitive proof of anything beyond a strange radio signal. Maybe that's all it is. A quirk of propagation. A forgotten military test. A numbers station that nobody admits to running.

But it transmits again in 43 hours. And I'll be listening. Because after 1,347 transmissions, I'm not ready to call it random.

Another entry for the log.

*Listening notes: If you have SDR equipment, the next transmission is approximately 1847 hours on July 3rd. I'm not asking anyone to believe anything. I'm asking: can you hear it too? And if you can — what do you hear that I'm missing?*
