Recorded at the wild Rockwork ocean cliff near Manzanita, Oregon USA yesterday morning (August 6th) at 1300 UTC, at least one strong Australian station on 531 kHz is in the following clip, with apparent ID's at 10 seconds ("Radio _____") and at 3:22. There apparently is another Australian station mixing in at times, and possibly the Kiwi station PI in an island language. Any suggestions or comments about the identity of these stations would be appreciated-- thanks!
