Abstract
Both moves are announced in band, on the per-block control bit of the continuous stream, in a fixed window of 104 control-bit periods every 1.2 s that no beacon or labels window ever uses. The window is there whether or not anything is announced; it carries zero bits when idle. Two payloads use it, each covered by a 4-byte keyed tag:
- Whole-carrier retune: {new_frequency, key_fingerprint}.
- Mix move: {mix id, new_frequency, key_fingerprint}, sent only on the carrier that carries the mix, only while the rack holds the move.
Neither carries a switch time, delay, countdown, count, position, profile, salt or list. The operator chooses the new frequency or the target carrier. The rack holds the change for a time it never sends (4 s in the embodiment, so a pack hears three or four copies). For a retune the rack then retunes its radio and sends nothing more on the old frequency. For a mix move the hold ends at the start of a labels window; in that block period the mix's name and id leave the old carrier's labels and its audio leaves the old carrier and starts on the new one: break before make, never on both.
A pack acts only on an announcement whose tag verifies under its key and whose fingerprint is its own, and, for a mix move, only if the mix id is the mix its user picked.
