Mbiri{{0}Way Radio Range Nezvinhu Zvinoikanganisa

Two-way radios, inozivikanwawo sewalkie-talkies, midziyo inogonesa kutaurirana chiriporipo pasina kuvimba nemanetiweki enharembozha. Iwo anoshandiswa zvakanyanya mukuchengetedzwa kweveruzhinji, bhizinesi, uye zviitiko zvekunze. Kuwanda kwavo kunokonzerwa nezvinhu zvakasiyana-siyana, uye kunzwisisa zvinhu izvi zvinogona kukubatsira kusarudza uye kuzvishandisa zvakakodzera.

Maredhiyo enzira mbiri-anowanzobva pamakiromita mashoma kusvika pamakumi emakiromita, asi pakuita, kazhinji ipfupi. Mumamiriro ezvinhu akanaka, akadai semapani akavhurika, asina kuvharika kana pakakwirira, midziyo yehunyanzvi ine-mabatisi emagetsi epamusoro uye maantenna anoshanda anokwanisa kuita nhambwe yemakumi emakiromita. Zvisineyi, munzvimbo dzakaomarara dzakaita sedzakavakirwa{4}pamusoro, nzvimbo dzine makomo, kana masango, kuvharika kwemasaini uye kuvhiringika kwenzira dzakawanda kunogona kudzikisa danho rinoshanda kusvika kumazana emamita kana kutoderera.

Transmitter simba chinhu chakakosha pakusarudza huwandu. Kazhinji kutaura, simba repamusoro rinoreva kureba kwechiratidzo chekufambisa. Civilian walkie-talkies inowanzoshandisa 0.5 kusvika 2 watts yemagetsi, ukuwo michina yehunyanzvi inogona kusvika pa5 watts kana kudarika. Antenna mhando uye kureba zvakakoshawo. Yakakwirira-maantenna ekuwana kwaakananga anonatsiridza zvakanyanya-kugona kutaura kwakasiyana, uye kuiswa kweyepamusoro kunowedzera kuvharika kwemasaini.

Zvemamiriro ekunze hazvigone kufuratirwa mukukanganisa huwandu hwe-maredhiyo enzira mbiri. Hunyoro, kunaya, uye sinou zvinogona kutora mamwe masaisai eredhiyo, ukuwo kukanganiswa kwemagetsi (semuenzaniso, kubva kumusoro-tambo dzemagetsi nemidziyo yemagetsi) zvinogona kukonzera kudzikira kwechiratidzo. Uyezve, kusarudzwa kwema frequency kwakakosha. VHF (yakanyanya kukwirira, 30-300MHz) ine kureba kwewavelength uye isina kusimba kupinda asi yakasimba diffraction, zvichiita kuti ive yakakodzera nzvimbo yakashama. UHF (ultra-high frequency, 300-3000MHz) ine hupfupi hwewavelength uye kupinza kwakasimba asi inovharika zviri nyore nezvipingamupinyi, zvichiita kuti ive yakakodzera nzvimbo dzemudhorobha.

Muchidimbu, mataurirwo eredhiyo-yenzira mbiri haisi kukosha kwakatarwa; inotemerwa nemusanganiswa wemidziyo paramita, mamiriro ekunze, uye frequency kusarudzwa. Vashandisi vanofanirwa kugadzirisa magadzirirwo emudziyo wavo zvinoenderana nezvavanoda chaizvo kuti vaone kutaurirana kwakakwana.
