Here's a couple minutes of my recording of Radio 4KZ, Queensland, on 5055 kHz. This segment runs from about 09:59:40 to 10:01:50 UTC on July 11. Recording was made on a WinRadio G33DDC using a SAL-12 antenna.

I was surprised to hear them on the backside of a minor geomagnetic storm, but there they were.

Sorry about the loud, chirping ute the intrudes intermittently.
