- Zvimwe zvinodiwa
Kuburikidza nemidziyo iyi, ruzha rwunoshandurwa nhanho nhanho, kutumirwa, uye pakupedzisira kugamuchirwa nekuridzwa neredhiyo yemushandisi. Mumidziyo iyi, FM transmitter, FM nhepfenyuro antenna, tambo uye mutsara wekuteerera zvinodikanwa, uye nhepfenyuro haigone kurarama pasina ivo. Mimwe michina inoda kusarudza kuti yowedzera here kunhepfenyuro zvichienderana nemamiriro chaiwo.
Vanoshanda pamwe chete sei?
Mumidziyo yataurwa pamusoro, FM kutepfenyura transmitter ndiyo yakakosha mudziyo wemagetsi, uye zvimwe zvigadzirwa zvemagetsi zvinoshanda zvakaitenderedza. Nekuti FM nhepfenyuro yekutepfenyura haingori midziyo yemagetsi yekutepfenyura masaini, asiwo nekuda kweizvi, nhepfenyuro yeFM inotepfenyura inotaridzawo mashandiro enhepfenyuro dzeredhiyo zvakanyanya.
Kushanda Frequency
Iyo frequency yekushanda yeiyo transmitter inosarudza frequency chinzvimbo cheredhiyo. Semuenzaniso, kana transmitter ikatumira redhiyo frequency pa89.5 MHz, frequency chinzvimbo cheredhiyo i89.5mhz. Chero bedzi redhiyo yakashandurwa ku89.5mhz, vateereri vanogona kuteerera kuchirongwa chenhepfenyuro.
Panguva imwecheteyo, iyo frequency renji yeinotumidzira yakasiyana, nekuti iyo yekutengesa FM frequency bhendi inotenderwa nenyika yega yega yakasiyana. Nyika zhinji dzinoshandisa 88.0 MHz ~ 108.0 MHz, nepo Japan inoshandisa 76mhz ~ 95.0 MHz frequency band, uye dzimwe nyika dziri kuEastern Europe dzinoshandisa 65.8 - 74.0 MHz frequency band. Iyo frequency yekushanda yeiyo transmitter yaunotenga inoda kusangana nekutengesa frequency bhendi renji inotenderwa munyika yako.
Kushanda Simba
Simba reiyo transmitter rinotarisa kuvharika kweredhiyo. Kunyangwe kufukidzwa kwechiteshi cheredhiyo kuchikanganiswa nezvinhu zvakawanda, zvinosanganisira simba remutakuri, kureba kwekuiswa kweantenna, kuwana kweantenna, zvipingamupinyi zvakatenderedza antenna, kuita kweiyo FM inogamuchira zvichingodaro. Nekudaro, iyo yekuvhara inogona kuverengerwa zvichienderana nesimba reiyo transmitter. Uyu ndiwo mhedzisiro yekuyedzwa kwemainjiniya efmuser. Pasi pemamiriro ezvinhu chaiwo, vatumiri vemasimba akasiyana-siyana vanogona kusvika pakuvhara kwakadaro, iyo inogona kushandiswa sereferensi yekukubatsira kusarudza simba reiyo transmitter.
Maitiro Ekushanda
FM radio station haishande nechigadzirwa chimwe chete chemagetsi. Kunyangwe FM nhepfenyuro inotepfenyura ndiyo yakakosha midziyo yemagetsi, inoda kubatana kwezvimwe zvemagetsi kuti ipedze zvakajairwa kutepfenyura zvirimo.
Yekutanga ndeyekutepfenyura zvemukati kugadzirwa - kutepfenyura zvemukati kugadzira zvinonzwika, kusanganisira izwi remushambadzi, kana vashandi vanoisa yakarekodhwa yemukati ruzha mukombuta. Kune zviteshi zveredhiyo zvehunyanzvi, vangangoda kushandisa musanganiswa uye magadzirirwo enzwi kugadzirisa uye kukwenenzvera izvi zvirimo kuti vawane zviri nani kutepfenyura zvirimo.
Ipapo kune kupinza kweruzha uye shanduko - iyo yakagadziridzwa uye yakagadziridzwa ruzha inoiswa mukati FM nhepfenyuro yekutepfenyura kuburikidza nemutsara wekuteerera. Kuburikidza neFM modulation, mutakuridzi anoshandura izwi risingazivikanwe kumuchina kuita chiratidzo chekuteerera chinogona kuzivikanwa nemuchina, kureva, chiratidzo chemagetsi chinomiririra odhiyo nekuchinja kwazvino. Kana iyo transmitter yakashongedzerwa neDSP + DDS tekinoroji, inoisa dhijitari chiratidzo chekurira uye kugadzirisa mhando yechiratidzo chekurira.
Nhepfenyuro uye kugamuchirwa kwemasaini eredhiyo - FM nhepfenyuro inotumira masaini emagetsi kune antenna, inoashandura kuita masaini eredhiyo uye nekuaparadzira. Inogamuchira mukati mekuvhara kwayo, seredhiyo, inogamuchira masaisai eredhiyo kubva kune antenna uye inoashandura kuita masaini emagetsi kuti aendeswe kune anogamuchira. Mushure mekugadzirisa nemugamuchiri, inoshandurwa kuita ruzha uye kutumirwa. Panguva ino, vateereri vanogona kunzwa kurira kweredhiyo.

Zvigadzirwa zvavo ndezvemhando yepamusoro, asi zvinounzawo matambudziko ekudhura. Kana iwe usina bhajeti rakakwirira kudaro, wadii kusarudza fumuser? Senyanzvi yenhepfenyuro yeredhiyo inopa, isu tinogona kupa yakazara redhiyo seti uye mhinduro ine yakagadzikana mhando uye yakaderera mutengo. Kana iwe uchida, tapota taura nesu. Isu tinoedza kuita kuti vatengi vedu vanzwe kunzwika uye kunzwisiswa
