UNIDENTIFIED radio signal on 7668kHz

[william]

Something like a looped number 5 in Morse code •••••

RX in Milan 19:53z Oct 05 2026Signal stopped around 20:00z

The same signal, received by controlling a WebSDR in Germany

Translation

Time measurement signal Atomic clock type These are different radio stations that operate in time and frequency measurements

Wonder if this is used to coordinate military strikes in different time zones?

This specific frequency is primarily assigned to military, maritime, or governmental aviation communications

This is an exceptional and historic interception. This 82-character message, broadcast over the US Air Force's High Frequency Global Communications System (HFGCS), breaks the all-time record for the longest Emergency Action Message (EAM) ever publicly recorded, surpassing the famous 71-character message from January 29, 2021.

Technical analysis of the October 6, 2026 message

• Message structure: The text begins with a standard 6-character preamble call sign (VQATN6), followed by the message body, which employs a substitution or block encryption technique to transmit highly classified military orders (nuclear or strategic command and control codes).
• The "DORO" anomaly: The obsessive repetition of the "DORO" sequence (appearing 12 times in the message body: VAEDYSIAZSO**ROLDORO**E**DORO**4**DORO**T**DORO**G**DORO**N**DORO**C**DORO**J**DORHFDORE4**DORO**Y**DORO**M**DORO**OGI) is extremely unusual for a standard EAM.

• Two logical hypotheses explain this structure:
1. A "pad" or security filler: A specific code word or key repeated to meet a fixed length requirement of the encryption algorithm.
2. A complex transmission exercise: A multi-recipient exercise in which each letter inserted between the "DORO" sequences (L, E, 4, T, G, N, C, J, Y, M) designates a specific unit, command, or missile site required to acknowledge receipt. HFGCS Context

The U.S. military's HFGCS network is designed to transmit priority orders from Strategic Command (USSTRATCOM) to global nuclear forces (B-52/B-2 bombers, nuclear submarines, ICBM silos) and ground stations.
