I assume this is meant to be listed at being at 6925, not 6928 USB as I've got a fair to good signal of a blues tune here in Denver. Thanks for the show!
EDIT... listening to the SDR recording, and it was first on at 0010 for about a minute. Blues song that got very strong before suddenly cutting out at 0011. Came back on at 0014 but distorted modulation, not a very strong signal. Better when it came back on at 0049.
