What I can understand from the waterfall and spectrum analysis
Reception via TWR kSDR Cyprus
This is clearly a carrier shifting upwards to around 8-9 kHz.  The
modulation dissipates in proportion with the carrier to a max length of
18kHZ reaching to around 11952KHz. The spectrum analyzer shows that the LSB
side has less modulation than he USB part
Today the signal 25/9  1z+ is centered on 11936.159 kHz. It is highly
variable to a range of ±100HZ More zoom could help but the
Here is the waveform as tested in an audio program : 13 HZ for the marked 1
second!
I posted this info also on the page

and hope laeter to add more info if possible
