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

SAUDI ARABIA 11936.143+ kHz Sept 18 at 1806 UT, very rapid

chirping vs Yemen service, S=9+20dB. Jamming from Iran? UTwente flails to

lock onto when tuned to 11935 kHz, but finally stix here when tuned to

11936.00 kHz.

(Glenn Hauser-OK-USA, via NASWA Electronic Flashsheet #1170 Sept 22)

11936.173 approx. kHz, wobbling carrier and upper side band signal of Yemen

excile radio Riyadh in Arabic. S=9+35dB signal into Doha Qatar SDR unit

remotedly at 15.20 UT on Tue Sept 24, hit heavily by probably Iranian

jamming signal - 23 kHz wideband - up to 11959.4 kHz - from Sirjan SW center?

[selected SDR options, span 12.5 kHz RBW 15.3 Hertz]
