Indlela Abasebenza Ngayo, Izinhlobo, Inhloso Nemithetho Yezomthetho
Ama-Scanners we-Radio ahlongozwa
Ama-Scanner ayinamarediyo kuphela afanele ukuskena ama frequency amaningi kuze kusakazwe ukusakazwa. Uma ukusakaza lokho kuphelile, isithwebuli singase siqale sibheke esinye isiteshi esisebenzayo. Imisakazo eminingi yemoto ihlanganisa uhlobo olufanayo lokusebenza kweskena, kodwa akuzona abathwebulayo beqiniso. Imisakazo yangempela yomsakazo ngokuvamile ikwazi ukuqapha ama frequency UHF, VHF kanye ne-WFM ngaphezu kwendima ebanzi yama-AM ne-FM ama-unit units ajwayelekile avunyelwe ukwamukela.
Indlela ama-scanners asebenza ngayo
Njengoba izinhlobo eziningi zokusakazwa kwemisakazo zihlala isikhathi esifushane, ezifana namaphoyisa nomlilo, isimo sezulu kanye nokuthunyelwa kwezimo eziphuthumayo, kungaba nzima ukuzitholela ngesandla. Bangase baqale nganoma yisiphi isikhathi futhi bangase baqede nganoma yisiphi isikhathi. Ukuze uthole futhi ulalele lezi zisakazo eziphephile, ama-scanners enza uhlelo lokusika phakathi kweziteshi. Lokhu kufezwa ngokusetha isithwebuli ukuhlola iziteshi ezimbili noma ngaphezulu, lapho kuzokuzungeza phakathi kwalezi zikhathi kuze kufike ukusakazwa. Izikrini zanamuhla zikwazi ukugcina izinkulungwane zeziteshi ezahlukene.
Uma isithwebuli sithola ukusakazwa okusebenzayo, sizoyeka okwesikhashana kuleso siteshi. Umsebenzisi angakwazi ukulalela ukusakaza noma ukhethe ukuqhubeka nokuskena. Uma umsebenzisi ekhetha ukulalela, isithwebuli sizoqala ukuseshwa futhi ngokuzenzekelayo uma ukusakaza kuphela.
Izinhlobo ze-Radio Scanners
Ama-scanners atholakale ekuhlotsheni okuhlukahlukene futhi eze nezinombolo eziningi zesici. Ezinye zezinhlobo ezivame kakhulu zomsakazo womsakazo zihlanganisa:
- iphathwe ngesandla
- ama-in-dash amayunithi
- amayunithi angaphansi kwe-dash
- scanners radio ekhaya
Amanye ama-scanners angaphansi kwe-dash akhiwe kuma-radios e-CB, lapho kungenzeka khona angakwazi ukuskena ibhande lesakhamuzi, i-UHF, i-VHF, nezinye izikhathi. Lezi zithwebuli zomsakazo nazo zingasakaza, kodwa kuphela kubhendi bendawo. Ngokuthakazelisayo, i-CB yilokho okusakazwa kwomsakazo womsakazo.
Inhloso ye-Radio Scanners
Ama-scanner we-radio anezinombolo eziningi ezisetshenziswayo, futhi abanye abantu abasebenzisa la madivayisi ngokusemthethweni bahlanganisa:
- izintatheli
- uphenyo lobugebengu
- izitimela (isitimela se-train)
- ama-hobbyists omsakazo
- izakhamizi eziphuthumayo noma eziphuthumayo ezingenzeka, njengesimo sezulu esinzima
Abalobi bezindaba kanye nabaphenyi bezobugebengu bangakwazi ukuqapha ama-radio frequencies othize ukucwaninga izindaba noma ukuqoqa ubufakazi, ngoba lezo ziteshi azivikelekile futhi zitholakale ngokukhululekile. Ama-hobbyists we-radio, kwezinye izandla, mane nje ujabulele ukulalela izinhlobo ezihlukahlukene zokusakazwa. Lolu hlobo lokusetshenziswa ngokuvamile luhilela ukulalela amaphoyisa wendawo kanye namafrimo omlilo, ukulawulwa kwezithuthi zomoya, noma ukusakazwa kwomsakazo wezulu. Amanye ama-hobbyists, njengama-railfans, ahlole izinhlobo ezithile zokusakaza.
Imibuzo yezomthetho ye-Radio Scanner
Ngaphambi kokuthenga nokusebenzisa isithwebuli somsakazo , kubalulekile ukuhlola kunoma yiziphi izinkinga zomthetho ezikhona endaweni yakho. Ama-scanner we-radio asemthethweni ngokwemithetho emikhulu eminingi yase-United States, kodwa kunamanani amaningi angaphandle nendawo. Ngokwesibonelo, eFlorida, akuvumelekile ukusebenzisa isithwebuli ukulalela ukusakazwa kwamaphoyisa.
Amanye ama-scanner akwazi ukungena kumasevisi omsaka okhohliwe noma ukucacisa amasignali efoni yeselula, kodwa lo msebenzi awukho emthethweni ezindaweni eziningi. Ezinye izinhlobo zokusetshenziswa kwesithwebuli, njengokuthola izibonakaliso ezihlabayo noma ukulalela ngocingo olungenawo ucingo, kungase kube nomthetho, yingakho kubaluleke kakhulu ukuqinisekisa imithetho yangakini ngaphambi kokuba uqale ukusebenzisa isithwebuli somsakazo.
