Missileer Watch

Missileer Watch is a small, independent project by Daniel Frenkel of Valar Systems in Oregon. It documents Emergency Action Messages heard on the HF Global Communications System, copied off air, and presents them as a browsable record rather than a live monitoring service. The site is explicit that what you see may be sample data from a development fixture, not live traffic.

The core of the site is a messages section and a listen page, with times given in UTC (Zulu) and the primary frequency noted as 11175 kHz USB. The page reads two public files, archive.json and status.json, and receiver status is shown separately. Recordings and decodes are released under CC0 1.0, with attribution appreciated.

It is aimed at shortwave listeners and radio hobbyists who already know how HFGCS transmissions work and want to review past EAMs or check archive data. Casual visitors looking for a real-time feed may find the waiting states confusing, since the site does not promise continuous live coverage.

A practical approach is to start with the “New here? Start here” link, then check the status and archive files before drawing conclusions from the messages list. Signing in is optional and sets a single cookie only to keep you signed in; there are no tracking cookies, and the privacy page explains what is kept and how to delete it. Overall, it is a focused reference for the HF monitoring community rather than a general news source.
