Frequencies
An archive of radio signals received by The Function's monitoring station. Every record is a real observation, kept apart from any automated analysis of it.

Priority channels
| Channel | Frequency | Mode | Monitoring |
|---|---|---|---|
| CB Channel 19 | 27.185 MHz | AM | Not yet monitored |
| CB Channel 9 | 27.065 MHz | AM | Not yet monitored |
These two channels are meant to be watched continuously, without interruption from scanning. "Monitored" appears here only when a receiver has reported the channel within the last fifteen minutes.

Unidentified signal case files
Case files appear here once the archive responds. A case file is opened only for a signal that has been observed more than once and remains unidentified.
Archive standards
- Records come only from real signals received by the station. Nothing is invented, simulated or filled in to make the archive look busy.
- Each record keeps three things apart: what was observed, what automated analysis concluded, and any identification that is not confirmed.
- Transcripts never fill in missing words. Unclear passages are marked [unintelligible] and uncertain words are marked [?word?].
- Receiving a signal does not make it publishable. Private, protected and encrypted traffic is not published, and no attempt is made to defeat encryption. Where publication is not clearly lawful, only metadata is published or nothing at all.
- A possible numbers-station match is listed as a candidate until the evidence confirms it. Encrypted number groups are never "decrypted".
- Receivers are named by alias only. Location, network details and equipment identifiers are never published.
- Decoded text is shown exactly as received, as plain text. It is never run, followed or treated as an instruction.
