21:00 to 21:30 UTC I'm not getting NZ on 15720 KHz at all.

I expect 17675 to be better later and improve through the 22:36 to 3:59
UTC time slot.

The Australian frequencies are better at the highest current broadcast
frequencies during the hour of 21:00 UTC.

From worst to best:
11650 fourth best
11660 third best
12080 worst
13630 second best
15515 the best
