Tere, Habr.<\/p>\n

Uues esimeses osas<\/a><\/noindex> K\u00e4ideldud on mitmeid signaale, mida saab vastu v\u00f5tta pikkade ja l\u00fchikeste lainetega. \u00dchtviisi huvitav on ka UHF (ultra-k\u00f5rgsagedus), kus leiab samuti midagi p\u00f5nevat.<\/p>\n

\"Mis
\nNagu esimeses osas, vaatleme signaale, mida saab arvuti abil ise dekodeerida. Neile, kes tahavad teada, kuidas see t\u00f6\u00f6tab, j\u00e4tkame postituse all.
\n<\/a><\/noindex>
\nEsimeses osas kasutasime hollandlast veebi vastuv\u00f5tjat<\/a><\/noindex> pikkade ja l\u00fchikeste laine vastuv\u00f5tmiseks. Kahjuks ei ole UHF-is sarnaseid teenuseid \u2014 sageduste vahemik on liiga lai. Seet\u00f5ttu peavad need, kes soovivad allpool kirjeldatud katseid kordustada, soetama oma vastuv\u00f5tja, millest \u00fcheks odavaks valikuks on RTL SDR V3<\/a><\/noindex>, mille saab osta hinnaga 30 $. Selline vastuv\u00f5tja katab vahemiku kuni 1,7 GHz, k\u00f5ik allpool kirjeldatud signaalid on just sellega vastu v\u00f5etud. <\/p>\n

Nii et alustame. Nagu esimeses osas, vaatame signaale sageduse suurenemise j\u00e4rjekorras.<\/p>\n

FM-raadio<\/h2>\n

\nIsegi FM-raadio ei \u00fcllata kedagi, meid huvitab selles RDS. RDS (Raadio Andmete S\u00fcsteem) olemasolu v\u00f5imaldab edastada digitaalseid andmeid \"FM-signaali sees\". FM-jaama signaali spekter p\u00e4rast demoduleerimist n\u00e4eb v\u00e4lja selline:<\/p>\n

\"Mis
\n
\nSagedusel 19 kHz asub pilottoon, ja tema kolmekordsel sagedusel 57 kHz edastatakse RDS signaal. Osakogrammil, kui m\u00f5lemad signaalid koos v\u00e4lja tuua, n\u00e4eb see v\u00e4lja umbes nii:<\/p>\n

\"Mis
\n
\nSiin on faasimodutusega kodeeritud madalsageduslik signaal sagedusega 1187,5 Hz (muide, sagedus 1187,5 Hz on samuti mitte juhuslik \u2014 see on 19 kHz pilottooni sagedus jagatud 16). Edasi, p\u00e4rast bititasandi dekoodeerimist, dekodeeritakse andmepaketid, mille t\u00fc\u00fcpide arv on \u00fcsna suur \u2014 peale teksti saadakse edastada n\u00e4iteks alternatiivseid sagedusi raadiojaama saatmiseks, ning kui sattuda teise piirkonda, saab vastuv\u00f5tja automaatselt seadistuda uuele sagedusele. <\/p>\n

Kohalike jaamade RDS-andmete vastuv\u00f5tmiseks saab kasutada programmi RDS Spy<\/a><\/noindex>. Seda saab \u00fchendada HDSDR-iga, kui valida FM-modulatsioon, signaali laius 120 kHz ja bitikiirus 192 kHz, nagu n\u00e4idatud pildil.<\/p>\n

\"Mis
\n
\nSeej\u00e4rel tuleb lihtsalt suunata signaal Virtual Audio Cable abil HDSDR-ist RDS Spyle (VAC seadetes tuleb samuti seadistada bitikiirus 192 kHz). Kui k\u00f5ik on \u00f5igesti tehtud, n\u00e4eme kogu teavet RDS-i kohta, palju rohkem, kui tavaline kodune raadiovastuv\u00f5tja n\u00e4itab:<\/p>\n

\"Mis
\n
\nLisaks FM-ile on v\u00f5imalik dekodeerida ka DAB+, sellest oli juttu. erinev artikkel<\/a><\/noindex>Venemaal ei toimi see veel, kuid teistes riikides v\u00f5ib see olla asjakohane.<\/p>\n

\u00d5husaade<\/h2>\n

\nAjalooliselt on \u00f5hus\u00f5idukites kasutatud amplituudmodulatsiooni (AM) ja sagedusala 118-137 MHz. Pilootide ja lennujuhtide suhtlus ei ole kr\u00fcpteeritud ning seda v\u00f5ib kuulata iga\u00fcks. Kaksk\u00fcmmend aastat tagasi \"t\u00f5mmati\" selleks tavalisi odavaid Hiina raadiovastuv\u00f5tjaid \u2014 piisab, kui nihutada heterod\u00fc\u00fcni kerasid, ja sagedus nihkub, kui vedab, siis k\u00f5rgematele sagedustele. Need, keda huvitab \"digitaalne arheoloogia\", v\u00f5ivad lugeda arutelusid foorumis radioscanner<\/a><\/noindex> 2004. aastast. Hiljem l\u00e4ksid Hiina tootjad kasutajatele vastu ja lisasid lihtsalt Air-sageduse vastuv\u00f5tjatesse (esimese osa kommentaarides soovitati mudelit Tecsun PL-660 v\u00f5i PL-680). Kuid loomulikult on spetsialiseeritud seadmete (nt AOR, Icom vastuv\u00f5tjad) kasutamine eelistatavam \u2014 need omavad m\u00fcrasummutust (heli kustub, kui signaali pole ja pidevat kriginat ei kostu) ja suuremat sageduste skannimise kiirus.<\/p>\n

Iga suur lennujaam kasutab \u00fcsna palju sagedusi, siin on n\u00e4iteks Pulkovo lennujaama sagedused, mis on saadud saidilt radioscanner:<\/p>\n

\"Mis
\n
\nMuide, erinevate Venemaa linnade (Moskvast, Peterburist, T\u0161eljabinskist ja m\u00f5nest muust) vestluste kuulamiseks saab veebis http:\/\/live.radioscanner.net<\/a><\/noindex>. <\/p>\n

Meie jaoks on \u00f5husaates huvitav digitaalne protokoll ACARS<\/a><\/noindex> (Aircraft Communications Addressing and Reporting System). Selle signaale edastatakse sagedustel 131,525 ja 131,725 MHz (Euroopa standard, erinevates piirkondades v\u00f5ivad sagedused erineda) need v\u00f5ivad erineda<\/a><\/noindex>). Need on digitaalsed paketid bittide m\u00e4\u00e4raga 2400 v\u00f5i 1200 bps, mille abil saavad piloodid vahetada s\u00f5numeid lennujuhtidega. Dekodeerimiseks MultiPSK-is tuleb signaal seada AM re\u017eiimi (vajalik on SDR-vastuv\u00f5tja, kuna signaali ribalaius on \u00fcle 5 kHz) ja suunata heli Virtual Audio Card abil. <\/p>\n

Tulemus on n\u00e4idatud ekraanipildil.<\/p>\n

\"Mis
\n
\nACARSi signaalide formaat on \u00fcsna lihtne ja seda saab vaadata programmis SA Free. Selleks piisab, kui avada salvestise fragment ja n\u00e4eme, et AM salvestise \"sisek\u00fcljel\" on tegelikult sagedusmodulatsioon.<\/p>\n

\"Mis
\n
\nJ\u00e4rgmiseks, rakendades kirjele sagedusdetektorit, saame me kergesti bitivoog. Tegelikult on kahtlane, et seda tuleb teha, kuna valmis programmide ACARS-i dekodeerimiseks on juba ammu kirjutatud.<\/p>\n

Meteorosaatjad NOAA<\/h2>\n

\nKuulates lendurite vestlusi, v\u00f5ib minna isegi k\u00f5rgemale - kosmosesse. Kus on meie jaoks huvitavad meteorosaatjad NOAA 15<\/a><\/noindex>, NOAA 18<\/a><\/noindex> ja NOAA 19<\/a><\/noindex>, edastades Maapinna pilte sagedustel 137.620, 137.9125 ja 137.100 MHz. Signaali saab dekodeerida programmi abil WXtoImg<\/a><\/noindex>.<\/p>\n

Vastuv\u00f5etud pilt v\u00f5ib v\u00e4lja n\u00e4ha umbes nii (pilt veebisaidilt radioscanner):<\/p>\n

\"Mis
\n
\nKahjuks (f\u00fc\u00fcsika seadusi ei saa petta, ja t\u00f5epoolest, Maa on \u00fcmmargune, kuigi mitte k\u00f5ik ei usu sellesse) saab satelliidi signaali vastu v\u00f5tta ainult siis, kui see lendab meie kohal, ja mitte alati on need lendud mugava aja ja horisondi \u00fcle nurga. Varem oli vajalik teada saada l\u00e4hima lennu kuup\u00e4ev ja kellaaeg programmi installimisega Orbitron<\/a><\/noindex> (ajalooline programm, mis eksisteerib alates 2001. aastast), n\u00fc\u00fcd on seda lihtsam teha veebis linkide kaudu https:\/\/www.n2yo.com\/passes\/?s=25338<\/a><\/noindex>, https:\/\/www.n2yo.com\/passes\/?s=28654<\/a><\/noindex> ja https:\/\/www.n2yo.com\/passes\/?s=33591<\/a><\/noindex> vastavalt. <\/p>\n

Satelliidi signaal on \u00fcsna vali ja kuuldav praktiliselt igale antennile ja igale vastuv\u00f5tjale. Kuid et vastu v\u00f5tta head kvaliteeti omavat pilti, on siiski soovitatav kasutada spetsiaalset antenni ja head horisondi vaadet. Soovijad v\u00f5ivad vaadata ingliskeelset \u00f5petust youtube'is<\/a><\/noindex> v\u00f5i lugeda \u00fcksikasjalikku kirjeldust<\/a><\/noindex>. Minul isiklikult ei olnud kannatust asja l\u00f5puni viia, kuid teistel v\u00f5ib-olla l\u00e4heb paremini.<\/p>\n

Pagingu s\u00f5numid FLEX\/POCSAG<\/h2>\n

\nKas pagingu side t\u00f6\u00f6tab veel korporatiivsete klientide jaoks Venemaal, ei ole mulle teada, aga Euroopas toimib see t\u00e4iesti, seda kasutavad p\u00e4\u00e4steteenistused, politsei ja erinevad teenistused. <\/p>\n

FLEX ja POCSAG signaale saab vastu v\u00f5tta HDSDR ja Virtual Audio Cable abil, dekodeerimiseks kasutatakse programmi PDW<\/a><\/noindex>. See kirjutati juba 2004. aastal ja liides vastab sellele, kuid imelikul kombel t\u00f6\u00f6tab see endiselt t\u00e4iesti.<\/p>\n

\"Mis
\n
\nSamuti on olemas dekooder multimon-ng, mis t\u00f6\u00f6tab Linuxi all, selle allikakoodid on saadaval githubis<\/a><\/noindex>. POCSAG edastusprotokolli kohta on samuti olnud eraldi artikkel, soovijad v\u00f5ivad sellega tutvuda t\u00e4iendavalt<\/a><\/noindex>.<\/p>\n

Puldid\/juhtmevabad l\u00fclitid<\/h2>\n

\nIsegi k\u00f5rgemal sagedusel, 433 MHz, on terve hulk erinevaid seadmeid - juhtmevabad l\u00fclitid ja toitepistikud, uksekellad, auto rehvir\u00f5huandurid jne. <\/p>\n

\"Mis
\n
\nNeed to consider that these are often cheap Chinese devices with simple modulation. There is no encryption involved, and a basic binary code (OOK \u2014 on-off keying) is used. The decoding of such signals has been discussed in a separate article<\/a><\/noindex>. We can use the ready-made decoder rtl_433, which can be downloaded siit<\/a><\/noindex>. <\/p>\n

\"Mis
\n
\nBy running the program, you can see various devices and (if there's a parking lot nearby) find out, for example, the tire pressure of your neighbor's car. This has little practical meaning, but from a purely mathematical perspective, it\u2019s quite interesting \u2014 the protocols of these signals are easy to decode.<\/p>\n

By the way, those buying such wireless switches should bear in mind that they are completely unprotected, and theoretically, your hacker neighbor with a HackRF or similar device could maliciously turn off your light in the bathroom at the most inopportune moment or do something similar. Personally, I don't worry about it, but if security is a concern, one could use more serious and expensive devices with full keys and authentication (Z-Wave, Philips Hue, etc.).<\/p>\n

TETRA<\/h2>\n

\nTETRA<\/a><\/noindex> (Terrestrial Trunked Radio) \u2014 is a professional system for corporate radio communication with quite extensive capabilities (group calls, encryption, merging several networks, etc.). And its signals, if not encrypted, can also be received via a computer and SDR receiver.<\/p>\n

A TETRA decoder for Linux existed quite a while ago<\/a><\/noindex>, but its setup was far from trivial, and about a year ago a Russian programmer created a plugin for receiving TETRA<\/a><\/noindex> for SDR#. Now this task can be solved in almost literally two clicks; the program allows you to display system information, listen to voice messages, collect statistics, etc.<\/p>\n

\"Mis
\n
\nThe plugin does not implement all the capabilities of the standard, but the main functions work more or less.<\/p>\n

According to Wikipedia, Tetra can be used in ambulances, police, rail transport, etc. Regarding its spread in Russia, I am unaware (it seems the Tetra network was used at the 2018 World Cup, but this is uncertain); those interested can check themselves \u2014 Tetra signals are easily recognizable and have a width of 25 kHz, as seen in the screenshot. <\/p>\n

Muidugi, kui v\u00f5rgus on kr\u00fcpteerimine lubatud (selline v\u00f5imalus on Tetras olemas), ei t\u00f6\u00f6ta pistikprogramm \u2014 k\u00f5ne asemel kostub vaid \"mullitamine\".<\/p>\n

ADSB<\/h2>\n

\nT\u00f5usame sagedusel veelgi k\u00f5rgemale, 1,09 GHz sagedusel edastatakse lennukite transponderite signaale, mis v\u00f5imaldab sellistel saitidel nagu FlightRadar24 n\u00e4idata m\u00f6\u00f6duvaid lennukeid. Seda protokolli on eelnevalt k\u00e4sitletud, seega ma ei hakka siin kordama (artikkel on niigi suur), soovijad saavad lugeda esimest<\/a><\/noindex> ja teist<\/a><\/noindex> osade.<\/p>\n

Kokkuv\u00f5te<\/h2>\n

\nKuidas n\u00e4ha, isegi 30-dollarise vastuv\u00f5tjaga on \u00f5hus palju huvitavat. Olen kindel, et siin on kaugel k\u00f5ik loetletud ja ma olen ilmselt midagi vahele j\u00e4tnud v\u00f5i ei tea. Soovijad v\u00f5ivad proovida iseseisvalt \u2014 see on hea v\u00f5imalus tutvuda mingi s\u00fcsteemi t\u00f6\u00f6p\u00f5him\u00f5ttega l\u00e4hemalt.<\/p>\n

Hobiraadiot ma ei k\u00e4sitlenud, kuigi see on samuti olemas UHF-l, aga artikkel on siiski ametlikest sidekanalitest.<\/p>\n

P.S.: Erakordselt koolih\u00e4kkeritele<\/a><\/noindex> v\u00f5ib m\u00e4rkida, et avatud eetris ei edastata t\u00f5eliselt salajast teavet juba umbes 50 aastat, seega ei tasu sellelt vaatenurgalt aega ja raha raisata. Aga sidep\u00f5him\u00f5tete ja erinevate inseneris\u00fcsteemide \u00f5ppimise seisukohalt on reaalsete v\u00f5rkude t\u00f6\u00f6ga tutvumine t\u00e4iesti huvitav ja \u00f5petlik.
