Omaziyo nehlabathi ibangela umdla irediyo, ungakwazi ukuqala nge ziingcinga esekethe, nto leyo eza kunika elungileyo kunokufumaneka khona amava kwi ungumzondeleli wireless ekuqaleni. Kuba Okokuqala, ungenza kuqokelela crystal iseti, imveliso yayo sele isiko elungileyo radio engahlawulwayo. Yena Kulula ukwenza, kunye nokwenza ukuba kwiiyure nje ezimbalwa. Oku kufuna ubuncinane nefikelelekayo zonke iseti nxalenye, Kakade ke, umnqweno ukusebenza. Kwisamkeli prototype tshin yokuqala yahlukile kwi ukuba sinako ukwenza utshintsho zingeyomfuneko ukuba bayile kwaye ukuvelisa kuba ibhodi yesekethe eziprintiweyo, kulula ukuba kumisa; ngokuba zonke iindawo bamba phezu kwetafile.
Lungisa kuyimfuneko ukuze nokuveliswa iinxalenye sixhobo. Le kakutsha iquka diode semiconductor receiver ngongoma (D9, D2), nto leyo a tshin. Beka of capacitors ukuba picofarads iwaka ezimbalwa, intonga ferrite (ubukhulu 7-8 mm) brand 400HH, 600HH kunye nobude-140 mm. Kwakhona kuyimfuneko ukulungisa uphawu wire NDV 1.2 (0,15-18 mm) yaye naziphi na Phones eliphezulu-resistivity coil ukungawi ubuncinane 1500 ohms. Zonke ezi radio zingathengwa evenkileni elithile.
Ngoku kugxininisa nokuveliswa jiko kuba yoba ferrite. Kuba oku kuyiphalusa kwiiseli ezininzi amaphepha evakalala kwi engundoqo ferrite kwaye iglu kubo. Ukuba ukufumana isakhelo elingqingqwa, nabanako lula zisuswe kwizikhondo. Ngoku umoya ujika ezingamakhulu amathathu wire pre-sizilungisile kwaye wenze kwiimpompo zethu zonke ambuyise ezintlanu. Impazamo esisiseko abo kuqala yenza crystal lakhe iseti kukuba onke amathuba mahlanu iluma wire, zalungisa kunye obluzhivaetsya. Shiya lo msebenzi kuba kamva, xa inkqubo ngokubhijela bend nje ngokwaneleyo ukwenza siqhubeke umoya wire. Ikhoyili eliphuma kuyimfuneko ukuba kulu ngephepha awomise.
Ngoku kuqokelela zonke izinto ngokungqinelana scheme elula. emuva ezipheleleyo coil kunye anode le diode liqhagamshelaniswe ukwamkelwa eriyali. Enye emuva kakhulu uqhoboshele phantsi enye yezona mveliso headphone. I-terminal lwesibini yoLungiso liqhagamshelene cathode le diode. Nonke nina obuziqokelele kunomathotholo wakho kuqala ngezandla zakhe. Ukuba zonke iisekethe ngumamkeli elibizelwe ndawonye ngokuchanekileyo, iqala ukusebenza ngoko nangoko. Icebo setting lwenziwa ngokuguqula inani amathuba kwi coil kwaye khetha i capacitor oludityaniswe ngaxeshanye headphones. Nale sifeze sandi.
Loo umdlali intlanzi kakuhle ezingqonge izikhululo zeradiyo abasebenza MW, Lw. Inyathelo elilandelayo isenokuba kwimveliso enye, kabini, kunye ndachithelwa balwamkele ezinokuthatha inani lee ngakumbi kwizikhululo. Kwaye kwixesha elide ukuvelisa i-isixhobosovavanyo lwemifanekiso elinzinyelwayo ngokuzenzekelayo isikhululo kwaye igcina kuyo. Le ngxuba scheme yesixhobo, amathuba amaninzi yabeka. Kodwa kwincoko yababini eyiyo yomfumani kuyimfuneko ukuba babe kwilebhu lakho kwikhaya izixhobo elungileyo test, phezulu kwamaza wenkunkuma, i oscilloscope, njl
