1690 WVON Chicago with open carrier right now 5:46 am CT. Hearing Montreal and at least one other, dominated by one with medical infomercial.
As of 6:05 the WVON silent period is over.

Details: An early awakening led to fiddling with the radio dial, and that led to three new catches:
The first was 1700 WEUP Huntsville, Ala. at 5:23 a.m., with music matched to the 10 kW station's stream. I noticed no hash from WVON, which is about six miles from me. So I tuned to 1690.
Open carrier! And two, maybe three stations under the carrier, which was full quieting, to use the ham phrase. One was music. It took some doing, but by 5:43, I'd pegged it as 1690 CJLO Montreal, matched to an SDR in Montreal. The 1 kW station's stream was way behind and would have been a tentative match. That's two. (And as the sun rose in Montreal, it faded out.)
On my CC Radio, on which those catches were made, I was getting the aforementioned medical infomercial, but I think that was a spurious signal. It didn't appear on by Sony ICF-2010, with or without my Tecsun AN-200 loop elsewhere in the house. What did appear with careful spinning of the lazy Susan was a talk program. At the top of the hour came an ad mentioning the locale and then the ID on 1690: WMLB Avondale Estates, Ga., an Atlanta suburb on 10 kW day power. That's three.
Five minutes later, the party ended with WVON throwing the switches to air programming again. But it was fun while it lasted.
