Must be what I heard during my walk home, holding the Sony ICF-2010 portable via shoulder strap.
6935 USB
Between approx 0120-0145 UTC, heard a bunch of gut bucket old school blues, Robert Johnson, John Lee Hooker, "Black Girl" (not sure if Leadbelly version), "You Gotta Move" (maybe Mississippi Fred McDowell, not sure).
No vocal ID heard, SSTV tones around 0130z, no way to decode from the field with the portable.
Signal fair to good, peaks and fades as I was walking. Had the whip extended only halfway, oriented horizontally to minimize local RFI.
The old Sony needs to be tweaked to center frequency for music in sideband. As it is now I tune 1/10th low, 6934.9, and the pitch is still off a bit. So it's harder to identify some music.
