What I can understand from the waterfall and spectrum analysis with two pictures
This is clearly a carrier shifting upwards to around 8-9 kHz. The modulation dissipates in proportion with the signal to a max length of 18 kHz reaching to around 11952KHz. Just see on how far it goes towards the right of the picture, The spectrum analyzer shows that the LSB part has less modulation than he USB part.
Today 25/9 around 10z the signal is centered on 11936.159 kHz. The supposed center is highly variable to a range of ±100Hz More zoom could help but as far as I tested it downgrades the clarity of the produced signal.
===================================
Here is the waveform with the chirping as tested in an audio program using the SAM mode : 10 HZ for the marked 1 second! There are two sub-chiprs that don't count which are shown with less amplitude than the other,
