My 6925 mystery was back again last night, peaking around 0730z this morning. I could hear audio of two stations at times, lending confirmation that this is some sort of mixing product. I'm curious if anyone else is hearing it - is it a mixing product in my SDR, or is it being generated at the transmitter site? One of the stations sounded like it was religious. It's usually just at the noise level most of the time, but will occasionally peak and become pretty strong, up to S7 at times. It's invariably heard right around this time, somewhere in the 0600-1000 window usually. And of course it never peaks around the TOH when there might be an ID.
