Currently listening to my overnight recording of RNZ Saturday Night, was not pleased to see that the switch from 13730 (uncopyable frequency) to 11725 (not great but much better here) took place at 0758-0759z rather than 0658-0659z as currently listed at RNZI's website. But as of 0823z the signal was SIO 444 with some QSB. I jumped ahead for a moment to make sure it did switch to 9700 at 0858-0859z because I'd have missed another hour if their engineers were generally off by an hour on their entire schedule, not just that one moment.
EDIT: The switchover happened as scheduled but not as usual. Typically there's a voiceover that interrupts the programming (because most of it is RNZ national, networked across the country via unchanging frequencies) saying that they're closing on this frequency and please retune, then it goes off, and appears about a minute later with the birdcall interval until the time pips. In this case the programming lasted until about 15 seconds before the hour and then QSY'd almost instantly - you could hear the end of the last song of that hour into the time pips instead of the interval.
Anyway, 9700's signal is also SIO 544 with some QSB. So a bit stronger but not the near-local quality a 555 signal would merit.
