Aceast\u0103 publica\u021bie completeaz\u0103 ciclul de articole \u00abCe se aude \u00een undele radio?\u00bb cu tema radiodifuziunii pe unde scurte.<\/p>\n

Mi\u0219carea de radioamatorism \u00een \u021bara noastr\u0103 a \u00eenceput cu asamblarea celor mai simple receptoare radio pentru a asculta transmisiile sta\u021biilor de radio difuzare. Prima construc\u021bie a unui receptor detector a fost publicat\u0103 \u00een revista \u00abRadioamator\u00bb, nr. 7, 1924. Radiodifuzia \u00een mas\u0103 \u00een URSS a \u00eenceput \u00een 1922 pe \u00abonda de trei mii de metri\u00bb (frecven\u021ba 100 kHz, banda DV) cu un transmi\u021b\u0103tor de 12 kW. sta\u021bia de radio im. Cominternului<\/a><\/noindex> (semnal RDW). Treptat, radiodifuzia acoper\u0103 banda SV, iar apoi, la sf\u00e2r\u0219itul anilor '20 \u0219i \u00eenceputul anilor '30, \u00eencepe s\u0103 se dezvolte difuzarea pe KV, inclusiv \u00een limbi str\u0103ine (difuzare extern\u0103<\/a><\/noindex>).
\n<\/a><\/noindex>
\nDifuzarea extern\u0103 pe KV a atins apogeul \u00een perioada \u00abr\u0103zboiului rece\u00bb ca unul dintre instrumentele eficiente ale luptei ideologice \u0219i propagandei. Dup\u0103 c\u0103derea \u00abcortinei de fier\u00bb, difuzarea \u00een limba rus\u0103 pe KV are, \u00een mare parte, un caracter informativ, cultural \u0219i de predicare.<\/p>\n

Reglementarea radiodifuz\u0103rii interna\u021bionale pe KV este gestionat\u0103 de o asocia\u021bie non-profit independent\u0103 HFCC<\/a><\/noindex>. De dou\u0103 ori pe an, la conferin\u021bele HFCC, se aprob\u0103 alocarea frecven\u021belor \u0219i a timpului de difuzare. Baze de date<\/a><\/noindex> disponibile pentru desc\u0103rcare de pe site. La baza de date activ\u0103 exist\u0103 acces interactiv<\/a><\/noindex>. Din 31.03.2019 a \u00eenceput sezonul de var\u0103 A19. Sezonul de iarn\u0103 B19 va \u00eencepe pe 27.10.2019 \u0219i va continua p\u00e2n\u0103 pe 29.03.2020.<\/p>\n

Ascult\u0103m radio\u2026<\/h1>\n

\n\u00cen Perm, oferta de programe radio pentru ascultare pe banda KV este modest\u0103. \u00cen timpul zilei, pe toate benzile de difuzare pe unde scurte, se pot recep\u021biona cel mult dou\u0103-trei, iar noaptea \u2013 unsprezece sta\u021bii radio vara sau c\u00e2teva zeci iarna.<\/p>\n

Pentru recep\u021bie, folosesc un echipament destul de \u00abbugetar\u00bb:<\/p>\n

1. Receptor radio de difuzare Tecsun PL-380.
\n2. Receptor radio de leg\u0103tur\u0103 SoftRock Ensemble II RX \u0219i HDSDR v.2.70<\/p>\n

\"Ce
\n\u00cen fotografia de mai sus, Tecsun PL-380 este setat pe frecven\u021ba de 11875 kHz (banda de 25 m). Difuzarea se face \u00een limba rus\u0103. Tema transmisiei: cultura chinez\u0103. Din baza de date HFCC \u00een format text afl\u0103m c\u0103 este Radio Interna\u021bional al Chinei, transmi\u021b\u0103torul se afl\u0103 \u00een Urumqi, puterea transmi\u021b\u0103torului este de 500 W, iar antena radiaz\u0103 pe azimutul de 308 grade.<\/p>\n

\u2026\u0219i transform\u0103m asta \u00eentr-o pasiune, sport sau colec\u021bie<\/h1>\n

\nPotrivit declara\u021biei HFCC, baza lor de date con\u021bine informa\u021bii despre 85% din difuzarea interna\u021bional\u0103 pe unde scurte, iar cele 15% neacoperite includ difuzarea local\u0103 \u00een \u021b\u0103rile Africii \u0219i Americii Latine, care nu necesit\u0103 reglementare interna\u021bional\u0103. Aceasta nu este \u00eentotdeauna pe placul entuzia\u0219tilor recep\u021biei radio, a\u0219a c\u0103 ei public\u0103 propriile baze de date complete. Baza de date EiBi<\/a><\/noindex> \u2013 este una dintre ele. <\/p>\n

Recep\u021bia semnalelor de la sta\u021biile de radio comerciale se nume\u0219te DXing<\/a><\/noindex>. Esenta acestui fenomen<\/b>: ascult\u0103torul de radio trimite unei sta\u021bii de radio un raport despre transmisiunea recep\u021bionat\u0103, iar administra\u021bia sta\u021biei de radio r\u0103spunde prin trimiterea unei c\u0103r\u021bi de confirmare (QSL) ca dovad\u0103 c\u0103 semnalul acestei sta\u021bii a fost recep\u021bionat de ascult\u0103tor. Un exemplu de carte QSL poate fi v\u0103zut aici<\/a><\/noindex>.<\/p>\n

Redac\u021biile de difuzare consider\u0103 rapoartele un element important de feedback. De exemplu, cu c\u00e2\u021biva ani \u00een urm\u0103, dintr-un interviu cu redactorul serviciului de difuzare \u00een limba rus\u0103 al Radio Taipei International<\/a><\/noindex> am aflat c\u0103 \u00een primele dou\u0103 s\u0103pt\u0103m\u00e2ni de difuzare \u00een limba rus\u0103 au avut senza\u021bia unei \u00abcomunic\u0103ri \u00een gol\u00bb, p\u00e2n\u0103 c\u00e2nd au primit un raport de la un radioamator din Rusia. De atunci, redac\u021bia difuz\u0103rii \u00een limba rus\u0103 a RTI face eforturi s\u0103 trimit\u0103 QSL fiec\u0103rei persoane care scrie.<\/p>\n

\u201ePragul de intrare\u201d \u00een DXing este sc\u0103zut: este suficient s\u0103 ai un receptor de difuzare. Entuzia\u0219tii comunic\u0103 pe forumuri \u0219i conferin\u021be, unde schimb\u0103 informa\u021bii despre sta\u021biile de radio recep\u021bionate, adresele birourilor QSL, anun\u021burile de difuzare. De asemenea, entuzia\u0219tii public\u0103 \u00een mod regulat ghiduri tematice \u0219i buletine. Ca exemplu de club DX, se poate men\u021biona Site-ul DX Novosibirsk<\/a><\/noindex>.<\/p>\n

Rezumat scurt<\/h4>\n

\nRecep\u021bia transmisiilor de la sta\u021biile de radio comerciale a fost \u0219i r\u0103m\u00e2ne o direc\u021bie important\u0103 \u00een mi\u0219carea radioamatorilor. \u00cen lumea modern\u0103, difuzarea interna\u021bional\u0103 pe unde scurte serve\u0219te nu doar scopurilor ideologice, ci \u0219i dialogului cultural.<\/p>\n

Pasiunea pentru recep\u021bia transmisiilor de la sta\u021biile comerciale nu necesit\u0103 investi\u021bii financiare serioase, ob\u021binerea de licen\u021be \u0219i validarea calific\u0103rilor.<\/p>\n

Autorul publica\u021biei nu este un entuziast DXing, dar sus\u021bine activ tot ceea ce apropie oamenii \u0219i faciliteaz\u0103 dialogul \u00eentre ace\u0219tia.
