Calibration Schedule

Regular weekly calibration slots, published changes and the next reference transmission.

Calibration sessions use the same pulse and carrier blocks as a tour, on one published reference frequency: the unmodulated carrier is exactly on that frequency, the third pulse is 25 ms and the PPS offset is 0. During the pulse and QST segments, the received frequency may differ slightly (see Rules) — use the carrier for frequency calibration.
