Bhuku rino rinozadzisa nyaya dzinoti “Chii chaunganzwa paredhiyo?” musoro weshortwave radio broadcasting.

Mufambiro mukuru weredhiyo weamateur munyika yedu wakatanga nekuungana kwevatambi veredhiyo vari nyore kuteerera nhepfenyuro. Iyo dhizaini yekugamuchira detector yakatanga kubudiswa mumagazini "Radio Amateur", Nhamba 7, 1924. Kutepfenyura kweredhiyo muUSSR kwakatanga muna 1922 pa "wave yemamita zviuru zvitatu" (frequency 100 kHz, DV range) ne. transmitter ine simba re12 kW nhepfenyuro dzakapihwa zita Comintern (fonera chikwangwani RDW). Zvishoma nezvishoma, kutepfenyura kweredhiyo kwakafukidza huwandu hweCB, uye mukupera kwe20s nekutanga 30s, kutepfenyura kweHF kwakatanga kukura, kusanganisira mumitauro yekunze (kutepfenyura kune dzimwe nyika).

Nhepfenyuro yekune dzimwe nyika paHF yakasvika pakakwirira panguva yeCold War seimwe yezvishandiso zvinoshanda zvekurwira pfungwa uye propaganda. Mushure mekudonha kweIron Curtain, kutepfenyura kwemutauro wechiRussian paHF kwainyanya kuve kwenhau, tsika uye kuparidza.

Kutepfenyurwa kwenhepfenyuro dzepasi rose paHF kunoitwa nesangano risiri rehurumende risiri purofiti HFCC. Kaviri pagore, misangano yeHFCC inobvumidza kugoverwa kwema frequency uye nguva dzekutepfenyura. Databases iripo yekurodha kubva kune saiti. Kune database iripo iripo interactive access. Kubva munaKurume 31.03.2019, 19, mwaka wezhizha weA19 wakatanga. Mwaka wechando weB27.10.2019 uchatanga muna Gumiguru 29.03.2020, XNUMX uye uchaenderera mberi kusvika Kurume XNUMX, XNUMX.

Kuteerera radio...

MuPerm, sarudzo yezvirongwa zveredhiyo yekuteerera mubhendi yeHF ishoma. Munguva yemasikati, pane ese mapfupi-wave nhepfenyuro mabhendi iwe haugone kugamuchira anopfuura maviri kana matatu, uye munguva yerima - gumi nemaviri nhepfenyuro muzhizha kana gumi nemaviri munguva yechando.

Kugamuchira ini ndinoshandisa zvakaringana "bhajeti" midziyo:

1. Nhepfenyuro yeredhiyo inogamuchira Tecsun PL-380.
2. Kukurukurirana nhepfenyuro yeredhiyo SoftRock Ensemble II RX uye HDSDR v.2.70

Mumufananidzo uri pamusoro, iyo Tecsun PL-380 inotaridzwa ku11875 kHz (25 m renji). Nhepfenyuro inoitwa muchiRussia. Dingindira rechirongwa: Tsika dzeChinese. Kubva kuHFCC dhatabhesi mune zvinyorwa zvemavara tinodzidza kuti iyi iChina International Radio, iyo transmitter iri muUrumqi, iyo transmitter simba i500 W, antenna inopenya muazimuth 308 degrees.

Isu tinogadzirisa SoftRock Ensemble II RX uye HDSDR v.2.70 pane frequency ye11875 kHz:

Dzvanya bhatani reFreqMgr kuti upinde muFrequency Manager uye uwane nhepfenyuro mudura reEiBi:

... uye ishandure kuita chirairo, mutambo kana muunganidzwa

Maererano neHFCC, dhatabhesi ravo rine data pamusoro pe85% yenhepfenyuro dzeHF dzepasi rose, uye 15% yasara inosanganisira kutepfenyura kwemuno muAfrica neLatin America, izvo zvisingade mitemo yenyika. Izvi hazviwanzoenderana neredhiyo vanofarira, uye vanoburitsa yavo, yakawedzerwa, dhatabhesi. Database EiBi - mumwe wavo.

Kutambira masaini kubva kunhepfenyuro dzeredhiyo kunodanwa DXing. Hunhu hwechiitiko+ Muenzaniso wekadhi reQSL unogona kutariswa pano.

Vapepeti venhepfenyuro vanoona mishumo sechinhu chakakosha chemhinduro. Semuenzaniso, makore mashoma apfuura kubva kubvunzurudzo nemupepeti Russian nhepfenyuro nhepfenyuro yeRadio Taiwan International Ndakaziva kuti kwevhiki mbiri dzokutanga dzokutepfenyura mumutauro wechiRussian, vakanga vaine manzwiro oku“taurirana pasina chinhu,” kutozosvikira vagamuchira mushumo waibva kune mumwe munhu aidzidza paredhiyo aibva kuRussia. Kubva ipapo, vapepeti venhepfenyuro yeRussia RTI vanga vachiedza kutumira maQSL kune wese akanyora.

Iyo "chikumbaridzo chekupinda" muDXing yakaderera: zvakakwana kuve neanogamuchira nhepfenyuro. Vanofarira vanotaurirana pamaforamu uye makonferensi, kwavanotsinhana ruzivo nezvezviteshi zveredhiyo zvakagamuchirwa, kero dzeQSL Bureau, uye zviziviso zvekutepfenyura. Vanofarira zvakare vanogara vachiburitsa zvinyorwa zvinyorwa uye tsamba dzenhau. Muenzaniso weDX kirabhu ndeye Novosibirsk DX saiti.

Pfupiso pfupi

Kugamuchirwa kwenhepfenyuro dzeredhiyo kwave uye kunoramba kuri nzvimbo yakakosha yeamateur radio movement. Munyika yanhasi, kutepfenyura kwekunze paHF hakushandi zvakanyanya pfungwa sezvinangwa zvenhaurirano dzetsika.

Iyo hobby yekugamuchira nhepfenyuro haidi kuisirwa mari yakakomba, kuwana marezinesi kana kusimbisa zvikwaniriso.

Munyori wekuburitswa haasi DXing anofarira, asi anoshingairira kutsigira zvese zvinounza vanhu pamwechete uye kukurudzira nhaurirano pakati pavo.
