I followed along on 5400, 4850, and 4800 kHz, through CODAR indeed made that last frequency hard to hear.
The art experiment was a combination of a woman (Amanda?) speaking and then some singing. My reception generally got better as 0630 UTC approached, but the speaking was never quite comfortably readable through the noise here.
