2255 Woman giving a talk / lecture about the evolution of the white lower class - white trsh / trailer trash, up to about 2331 when the xmtr. went out of wack and into tones.
Not sure if it was related, but a series of SSTV were sent starting 2347. None decoded here.
S 3 - 5 here. Signal quality improved a great deal after 2315.
The 6925 AM station became somewhat audible when the tones started. Nothing from it until then.
