If using a good portable SW radio, what frequencies can
I hope to get for Radio Australia and RNZI during the local
late afternoon through evening hours?

UTC 2100 - 0400 approximately

I get RA 9580kHz really well during local early morning hours
and RNZI 9885 was coming in great this morning. I want to hear
them at night (my time) also.
