Yes, I ran across the website of the Texas Part 15 station... would be great but seems improbable.
Well, I am hearing it again this morning at 1150 UTC, well after local sunrise. I think I've got a semi local pirate!
The plot thickens... I just (1315 UTC) heard an ID of WXLV. Pretty sure I copied it correctly. That call seems to be used by a NC TV station, as well as an FM station (probably Part 15) at a college in Allentown PA.
