It's been generally RFI-quiet here ...

Just got 0.16" of sudden downpour a little earlier
and came inside.

Turned on the rig and from 550kHz - 14+mHz I heard
this in AM mode:


I did not hear it on 17m or higher on my IC-7200
using the ZeroFive 43' vertical.

Anyone recognize the sound's likely source, please?

Thanks - David KD4E
