Hello there, I managed to record 10Mhz of sample rate which u can find here: https://transfer.sh/vxuyz7zPyH/SDRSharp_20230928_110124Z_676100000Hz_IQ.wav
It seams that interfering signal is infact DVB-T on Channel 46 with Center frequency of 674 MHz I also managed to capture that interference channel which you can find here: https://transfer.sh/MFmwlKWYG8/AirSpy_20230928_132144Z_674000kHz_IQ.wav I hope the signal is strong enough to be able to decode something I believe the MUX is M2 from PayTV Provider called EvoTv from Croatia: https://www.hrvatskitelekom.hr/evotv How cuold this interfere me I am receiving here: https://maps.app.goo.gl/YeNntbpAk25eMjjC8 I am trying to receive 20kW Federalna Televizija on Channel 47 (PAL B/G) from Velika Gomila: https://fmscan.org/transmitter.php?t=1100309 The interference signal is located in Lička Plješivica, Mirkovica and Stipanov Grič (DVB-T): https://hr.wikipedia.org/wiki/Dodatak:Popis_oda%C5%A1ilja%C4%8Dkih_objekata_OiV-a The interference signal is on Channel 46, my Signal of interest is on Channel 47, thats one channel apart, how can interference even happen I a bit confused V V čet., 28. sep. 2023 ob 16:25 je oseba Fabian Schwartau < fab...@opencode.eu> napisala: > Do you know this site? > https://www.sigidwiki.com/wiki/Signal_Identification_Guide > > I had a short peek and could not find anything, but you may have a bit > more patience. > > Best > Fabian > > Am 27.09.23 um 13:21 schrieb veso...@gmail.com: > > > > Hello there all, I hope someone can help me > > > > I am trying to watch some television on CH47 (679.25Mhz) > > > > I am in Slovenia and I am trying to receive and watch Federalna > > Televizija transmitting from Bosnia and Herzegovina (BiH) > > > > But there is very anoying signal bothering me, you can see the problem > > here: https://youtu.be/wt4vEfu7yEI?si=XDQ8wQ-rK-lb8LMW > > > > Instead of seing PAL and hearing sound, I see this anoying lines and > > hear digital data :( > > > > So I decided to bring my Airspy R2 to visually see and record some IQ > > data on whats going on > > > > So this is what I recorded: > > > https://transfer.sh/dMhDtqnodK/baseband_679250000Hz_14-23-42_26-09-2023.wav > > > > Center frequency was 679.25Mhz but sadly I was only able to record about > > 2.5Mhz of Bandwith, because my phone could not handle full 10Mhz > > > > As you can see PAL was bearly able to get through this jamming signal > > > > At first I thought it could be 600Mhz 5G NR which is sadly right where I > > want to receive (663 – 698 Uplink, 617 – 652 Downlink), but thats only > > for US, not Europe > > > > The next suspect could be 5G Extended Lower SMH (which has downlink from > > 698 – 716) but its 20Mhz above my signal, PAL only needs about 6-8Mhz so > > this should not be a problem > > > > Then I thought maybe LTE Lower SMH on 700MHz could be the culprit, which > > again doesnt make any sense (Downlink on 699 – 716Mhz) > > > > I hope something could be done > > > > At least to figure out what signal that is so I can complain to relevant > > local authorities > > > > I am there for a 3 more days, so if needed I can do more messurments > > > > Sadly I only brought Airspy HF+, and Airspy R2 with me nothing more > > capable bandwith vise > > > > I also have Samsung Galaxy S10+ if it can maybe help in messuring LTE > > signals somehow > > > > Thanks to everyone for anwsering > > -- > > Sent from myMail for Android > > > >
