Radio Japan schedule change?

Does anyone know if Radio Japan has changed their broadcast schedules?
I listen to their broadcast to North American on 9535 KHz at 17:00 UTC.
When I tuned in both this Tuesday and Thursday (local California time)
there was a broadcast in Japanese up to 17:00, then they went off the
air. It also seems during the day that the 31 meter band is better to
listen to than frequencies above 12000 KHz. Is this due to the change
of seasons or propogation? Denny Dollahon.
