Right, it's not IBOC (and it's not power supply noise). It's actual
low frequency modulation on 1190, complementary in each sideband
(so you don't hear it unless you're receiving one sideband only).

I'd doubt you could hear it at night since there are so many other
stations competing for the frequency, unless you're really close.

Whether it's WOWO or not I can't say, but it seems to be most likely,
since it's the only 1190 station really in competition for Central
Ohio in the daytime.

WFAN 660 had the same sort of thing for a couple of months last winter,
only it was a phase modulation introduced by their broken power supply,
inaudible unless you were hearing only one sideband.

This sounds more like a low bandwidth digital subcarrier.
