See postitus t\u00e4iendab artiklite seeriat \u201eMis toimub raadioeetris?\u201d teemaga raadiotehnoloogia l\u00fchikestes lainetes.<\/p>\n

Massiline raadiovastuv\u00f5tu liikumine meie riigis algas lihtsate raadiovastuv\u00f5tjate kokkupanemisest, et kuulata ringh\u00e4\u00e4lingu\u00fclekandeid. Esmakordselt avaldati detektori vastuv\u00f5tja konstruktsioon ajakirjas \u201eRaadiovastuv\u00f5tja\u201d, nr 7, 1924. aastal. Massiline raadiov\u00e4iksus N\u00f5ukogude Liidus algas 1922. aastal \u201ekolme tuhande meetri laine\u201d (sagedus 100 kHz, l\u00fchike laine) saatjaga, mille v\u00f5imsus oli 12 kW. Kominterni raadiojaam<\/a><\/noindex> (kutsung RDW). Aja jooksul laienes raadiov\u00f5tt l\u00fchilainega, ja siis 20. sajandi 30. aastate alguseks hakati arendama ka KVsaatamist, sealhulgas v\u00f5\u00f5rkeeltes (v\u00e4lismaised edastused<\/a><\/noindex>).
\n<\/a><\/noindex>
\nV\u00e4lismaised edastused KVs saavutasid oma \u00f5itseaegade \u201ek\u00fclma s\u00f5ja\u201d ajal kui efektiivne ideoloogilise v\u00f5itluse ja propaganda vahend. P\u00e4rast \u201eraudset eesriiet\u201d on venekeelsed edastused KVs enamasti uudiste, kultuuri ja jutlustamise iseloomuga.<\/p>\n

Rahvusvahelise raadiov\u00f5tte KVs reguleerib mittetulundus\u00fchingu reaalne organisatsioon HFCC<\/a><\/noindex>. Kaks korda aastas heaks kiidetakse HFCC konverentsidel sageduste ja raadioaja jaotamine. Andmebaasid<\/a><\/noindex> on allalaetavad veebisaidilt. Juurdep\u00e4\u00e4s olemasolevale andmebaasile on interaktiivne juurdep\u00e4\u00e4s<\/a><\/noindex>. Alates 31.03.2019 algab suvine rada A19. Talvine rada B19 algab 27.10.2019 ja kestab kuni 29.03.2020.<\/p>\n

Kuulame raadiot\u2026<\/h1>\n

\nPermis on KVs raadioprogrammide valik suhteliselt vaene. P\u00e4eva jooksul k\u00f5ikidel l\u00fchilainete sagedustel suudab vastu v\u00f5tta mitte rohkem kui kaks-kolm ja pimedas - k\u00fcmme raadiojaama suvel v\u00f5i paar tosinat talvel.<\/p>\n

Vastuv\u00f5tt, mida kasutan, on piisavalt \u201eeelarveline\u201d varustus:<\/p>\n

1. Raadiovastuv\u00f5tja Tecsun PL-380.
\n2. Raadiovastuv\u00f5tja SoftRock Ensemble II RX ja HDSDR v.2.70<\/p>\n

\"Mis
\n\u00dclaltoodud fotol on Tecsun PL-380 h\u00e4\u00e4lestatud sagedusele 11875 kHz (25 m laine). Edastus toimub vene keeles. Saate teema: hiina kultuur. HFCC andmebaasist tekstivormingus saame teada, et see on Rahvusvaheline Hiina Raadio, saatja asub Urumqis, saatja v\u00f5imsus on 500 W, antenn kiirgab 308 kraadi suunas.<\/p>\n

H\u00e4\u00e4lestame SoftRock Ensemble II RX ja HDSDR v.2.70 sagedusele 11875 kHz:<\/p>\n

\"Mis<\/p>\n

\u2026ja muudame selle hobi, spordi v\u00f5i kogu kollektiiviks<\/h1>\n

\nHFCC v\u00e4idab, et nende andmebaasis on andmed 85% rahvusvahelisest l\u00fchilainete edastamisest, samas kui \u00fclej\u00e4\u00e4nud 15% sisaldab kohalikku edastamist Aafrika ja L\u00f5una-Ameerika riikides, mis ei vaja rahvusvahelist regulatsiooni. See ei rahulda alati raadiovastuv\u00f5tu entusiaste, kes koostavad oma t\u00e4iendatud andmebaase. Andmebaas EiBi<\/a><\/noindex> on \u00fcks neist. <\/p>\n

Edastusraadiost signaalide vastuv\u00f5tmist nimetatakse DXing<\/a><\/noindex>. Selle n\u00e4htuse olemus<\/b>: raadiokuulaja saadab raadiostatsioonile raporti vastuv\u00f5etud \u00fclekandest, mille peale raadiostatsiooni haldus saadab vastuseks t\u00f5endikaardi (QSL), et kinnitada raadiovastuv\u00f5tu signaali vastuv\u00f5tmist. N\u00e4idist QSL-kaardist saab vaadata siin<\/a><\/noindex>.<\/p>\n

Eetriredaktsioonid k\u00e4sitlevad raporteid kui olulist tagasiside elementi. N\u00e4iteks mitu aastat tagasi intervjuust Taiwani Rahvusliku Raadio Venekeelse Teenistuse<\/a><\/noindex> toimetajaga, sain teada, et nende venekeelsel eetris olemise esimesed kaks n\u00e4dalat oli tunne nagu \"suhtlemine t\u00fchjusesse\", kuni nad said raporti raadiovastuv\u00f5tult Venemaalt. Sellest ajast peale p\u00fc\u00fcab RTI vene toimetus saata QSL iga\u00fchele, kes kirjutab.<\/p>\n

\u201eSisenemise barj\u00e4\u00e4r\u201c DXingusse on madal: piisab raadiovastuv\u00f5tja olemasolust. Entusiastid suhtlevad foorumites ja konferentsidel, kus vahetatakse teavet vastuv\u00f5etud raadiostatsioonide, QSL-b\u00fcroode aadresside ja eetrireklaamide kohta. Samuti avaldavad entusiastid regulaarselt temaatilisi k\u00e4siraamatuid ja teadete lehti. N\u00e4iteks DX-klubi toomiseks v\u00f5ib tuua Novosibirski DX sait<\/a><\/noindex>.<\/p>\n

L\u00fchikokkuv\u00f5tted<\/h4>\n

\nRaadiostatsioonide edastuste vastuv\u00f5tt on olnud ja j\u00e4\u00e4b raadioharrastajate liikumise oluliseks suunaks. Kaasaegses maailmas on l\u00fchilainete edastamine pigem kultuuride dialooge teeniv, mitte ideoloogiline.<\/p>\n

Raadiostatsioonide edastuste vastuv\u00f5tmine ei n\u00f5ua suuri rahalisi investeeringuid, lubade saamist ega kvalifikatsiooni t\u00f5endamist.<\/p>\n

Autor ei ole DXing entusiast, kuid toetab aktiivselt k\u00f5ike, mis toob inimesi kokku ja soodustab nende vahelist dialooge.
