Posting this for my sibling. I do have an audio recording, and we're still getting it right now:

From my radio in the Mojave Desert, I noticed something unusual last night that I heard on 590KHz. It was a whining, grinding-like noise. I checked again in the morning and it showed up another receiver on the following frequencies (all in KHz): 590, 620, 690, 870-990, 1110, and 1610. It doesn't seem to be affecting local stations all that much except the occasional noise on KWDJ at 1360 KHz.
I have made a recording of the audio log. It seems to be appearing on other receivers too.
