Momwe Akugwirira Ntchito, Mitundu, Cholinga ndi Mafunso Alamulo
Mafilimu Amatanthauzidwa
Akanema ndi makanema okha omwe amatha kufufuza maulendo angapo mpaka mawotchi atapezeka. Pamene izo zatha, scanner akhoza kuyamba kuyang'ana njira ina yogwira ntchito. Ma radiyo ambiri amagwiritsa ntchito njira zofanana, koma sizowona. Mawunivesiti enieni nthawi zambiri amatha kuyang'anitsitsa maulendo a UHF, VHF ndi WFM kuphatikizapo magulu ambiri a AM ndi FM omwe maulendo oyambira nthawi zonse amapangidwa kulandira.
Mmene Akanema Amagwirira Ntchito
Popeza mitundu yosiyanasiyana ya mauthenga a pa wailesi ndi yochepa, monga apolisi ndi moto, nyengo ndi zochitika zina zam'dzidzidzi, zingakhale zovuta kuzipeza mwapadera. Iwo akhoza kuyamba nthawi iliyonse ndipo akhoza kutha nthawi iliyonse. Kuti mupeze ndi kumvetsera zofalitsa zazing'onozi, zojambulazo zimangotengera njira yopumula pakati pa makanema. Izi zimachitika poika scanner kuti ayang'ane njira ziwiri kapena zingapo, panthawi yomwe idzasinthasintha pakati pa maulendowa mpaka msonkhano ufike. Zojambula zamakono zimatha kusunga njira zambirimbiri zosiyana.
Pamene pulogalamu yowunikira imapezeketsa kufalitsa kwachangu, idzaima pa njirayo. Wogwiritsa ntchitoyo amatha kumvetsera kuulutsa kapena kusankha kupitiriza kuyesa. Ngati wogwiritsa ntchitoyo amamvetsera, chojambulacho chiyamba kuyambanso kufufuza nthawi yomweyo pamene ntchitoyo itatha.
Mitundu Yopanga Mafilimu
Akanema akupezeka mumasintha osiyanasiyana ndikubwera ndi zida zosiyanasiyana zosiyana. Zina mwa mitundu yofala kwambiri ya ma scandiyo ndi awa:
- zojambulajambula
- mu-dash ma unit
- pansi-dash amayunitsi
- makanema a pawuni
Ma scan scan ena amamangidwa m'ma CB, ndipo nthawi zina amatha kusanthula gulu la anthu, UHF, VHF, ndi maulendo ena. Mawunivesiti awa amatha kufalitsa, koma pa gulu la nzika. Chochititsa chidwi, CB ndi chimene chinayambitsa makanema a wailesi.
Cholinga cha Mafilimu
Masakanema a wailesi ali ndi ntchito zambiri ndithu, ndipo ena mwa anthu omwe amagwiritsa ntchito zipangizozi mwalamulo amaphatikizapo:
- atolankhani
- ofufuza milandu
- njanji zamtunda (sitima ya sitima)
- ovumbulutsira wailesi
- nzika zosayembekezereka kapena zoopsa, monga nyengo yovuta
Atolankhani ndi ofufuza milandu amatha kufufuza maulendo ena a pawailesi pofuna kufufuza nkhani kapena kusonkhanitsa umboni, popeza kuti maulendowa sakhala otetezeka komanso amakhala omasuka. Mafilimu opanga mafilimu, mwa manja ena, amangokondwera kumvetsera zofalitsa zosiyanasiyana. Kugwiritsa ntchito kotereku kumafuna kumvetsera apolisi apamtunda ndi maulendo a moto, kayendetsedwe ka kayendetsedwe ka ndege, kapena mauthenga a pawailesi. Ena opangira mafilimu, monga njanji zamatabwa, amayang'ana mitundu yeniyeni ya mauthenga.
Mafunso Ophwanya Malamulo a Radiyo
Musanagule ndi kugwiritsa ntchito wailesi , ndizofunika kufufuza zomwe mungathe kuchita m'deralo. Masakanema a wailesi amaloledwa mwakhama m'madera ambiri a United States, koma pali zochepa zapakati pa dziko ndi dziko. Mwachitsanzo, ku Florida, n'kosaloleka kugwiritsa ntchito scanner kuti imvetsere mauthenga apolisi.
Ma scanner ena amatha kugwiritsira ntchito mawonekedwe a wailesi ya trunked kapena kupanga zizindikiro za foni zam'manja, koma ntchitoyi ndi yosaloledwa m'malamulo ambiri. Mitundu ina yamagwiritsidwe ntchito ka scanner, monga kulandira zikwangwani zowonongeka kapena kumvetsera pa telefoni zopanda zingwe, zingakhalenso zoletsedwa, ndicho chifukwa chake ndikofunikira kutsimikizira malamulo kumudzi wanu musanayambe kugwiritsa ntchito wailesi.
