At around 2210, I noticed a station on 870, but only the LSB was visible in the waterfall (or audible). They were playing bluegrass music. My guess was WPWT, TN based on the programming. But LSB only?
A few minutes later, they got buried by IBOC from 880. Now hearing some talk radio on the 870 USB, maybe WWL, no ID yet.
Any guesses? I'll have to try again tomorrow.
