SAUDI ARABIA 11936.207 kHz approx. peak of Riyadh's carrier on upper side flank, at 14.46 UT on Wed Sept 25, S=9+35dB noted on SDR remotedly in Doha, Qatar, ME.73 wolfie df5sx From: Zacharias Liangas via groups.io Sent: Wednesday, September 25, 2024 1:21 PM
Subject: Re: [WOR] ARS Riyadh Yemen excile radio on 11936v kHz and - probably - Iranian Sirjan site jamming up to 11959v kHz 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 https://zachs-radiopage.blogspot.com/2024/09/comenting-on-problem-happened-in-sanna.html and hope laeter to add more info if possible _ Hard-Core-DX mailing list Hard-Core-DX@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/hard-core-dx http://www.hard-core-dx.com/

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] (wb df5sx, wwdxc BC-DX TopNews & hcdx Sept 24) _ Hard-Core-DX mailing list Hard-Core-DX@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/hard-core-dx http://www.hard-core-dx.com/

I see and hear the same in Masset. Very strong at 20:56. The chirping extends up to 11955 kHz, but strongest between 11936 and 11940. 73, Walt
