NEET INTEL GitHub

NEET INTEL is a research project documenting the High Frequency Global Communications System (HFGCS) and the Emergency Action Messages (EAMs) broadcast on it. The HFGCS is a US Air Force shortwave network used to relay short, encoded messages to military forces. The transmissions are public — anyone with a shortwave receiver can hear them — but the messages themselves are deliberately opaque, and little has been published about how they are structured or how their patterns shift over time. This site collects the project's analyses, recordings, and reference material in one place.

If you are new to the HFGCS

Start with the HFGCS FAQ for a plain-language overview, then browse the HFGCS Wiki tab for additional information.

If you came for EAM structure analysis

The EAM Structure Analysis tab groups EAMs by character length and highlights repeating segments across messages. The "How to read these heatmaps" page explains the visualization.

If you came for the recordings

The NEET INTEL YouTube tab indexes every video in the DCRP (early daily compilations) and the DTCP (daily timecards with transcribed EAMs).

If you are tracking SKYMASTERs

The SKYMASTER tab catalogs SKYMASTER and FAKEMASTER events from 2023 onward, with 2026 forecasts and a year-over-year comparison.

Everything else

The Miscellaneous tab links to additional pages that do not fit cleanly under the categories above.

Contact

The Contact and Support tab lists ways to reach NEET INTEL and to support the project. Tip: ← / → switches tabs from the keyboard.

Emergency Action Messages are known to be highly structured. These pages group EAMs by character length and analyze them for repeating segments to identify candidate structural elements. Colored positions indicate possible pattern segments across messages. Click any colored position to highlight additional instances of that pattern.

Note: If the browser is unable to display the entire text of messages, the display automatically switches from individual characters to an abstract timeline view where colored segments represent pattern positions. (For desktop devices, try reducing the font size. For mobile devices, try turning your device to landscape mode to increase the vertical space.)

HFGCS EAM DAILY COMPILATION RECORDINGS PROJECT

The HFGCS EAM DAILY COMPILATION RECORDINGS PROJECT (DCRP) is the first attempt by NEET INTEL to collect recordings of EAMs broadcast on the HFGCS and share them with a wider audience. Unlike the later NEET INTEL DAILY TIMECARD PROJECT (DTCP), this series does not necessarily reflect comprehensive 24/7 HFGCS monitoring, and many of the videos represent a “whatever I happened to hear that day” effort, though the series does become more ambitious by its end (setting up for the more ambitious DTCP). Originally 100+1 videos (owing to 23022 being split into two parts), an additional 7 videos (after the series concluded) that are functionally similar have been classified as part of this project.

NEET INTEL DAILY TIMECARD PROJECT

The NEET INTEL DAILY TIMECARD PROJECT (DTCP) is the successor to the HFGCS EAM DAILY COMPILATION RECORDINGS PROJECT. The project generates daily timecards of transcribed Emergency Action Messages (EAMs) and/or Force Direction Messages (FDMs) broadcast by the US military over the High Frequency Global Communications System (HFGCS), paired with jpop, kpop, and occasionally cpop. Part 1 is comprehensive, starting 230623 and ending 240201, representing a 7-month period of continuous and near-comprehensive HFGCS coverage. The remainder of the project covers mostly non-consecutive dates, with several shorter periods of continuous coverage included.

An HFGCS Wiki is a proposed project by NEET INTEL to provide a centralized repository of information about the HFGCS and EAMs. The scale of a project is too ambitious for a single person, but NEET INTEL initiated a pilot project in December 2025 to demonstrate what it could look like. Below are some examples of the Wiki's pages as saved by archive.org.
