Looks like DSB or over-modulated AM on the SDR waterfall? Some distorted audio if tuned in USB or LSB.
Checking the SDR recording, sign on was 0020, there was an ID by a YL at 0021 as "No Post Pirate Radio WNPP"
0044 "You're listening to WNPP, No Post Pirate Radio, broadcasting from heart of the great plains."
0126 Off?
Not sure if it was due to QRM or distortion, but unfortunately the broadcast was mostly unlistenable here.
