Kudzivirirwa kwemheni chinhu chakakosha chemasangano anoshanda midziyo yemagetsi inotarisisa, kunyanya indasitiri yenhambadzi. Zvinoenderana neyekutanga mutsara wekudzivirira kubva kumheni uye yekuvhiringidza voltage ndiyo inovhara system. Kunze kwekunge magadzirwa uye akaiswa nenzira kwayo, chero dziviriro yekudzivirira haizoshanda.
Imwe yeTV yedu yeTV Transmitter iri pamusoro pegomo 900-tsoka-yakareba uye inozivikanwa nekuwana mheni. Ini ndichangobva kupihwa kuti titonge nzvimbo dzedu dzese dzekutumira. Naizvozvo, dambudziko rakaendeswa kwandiri.
Mheni yekurova muna 2015 yakakonzera kubuda kwemagetsi, uye jenareta haina kumira kumhanyira kumazuva maviri akateedzana. Pandakaongorora, ndakaona kuti iyo yekushandisa inoshanduka inoshanduka fuse yakanga yopererwa. Ndakaona zvakare kuti iyo ichangobva kuisirwa otomatiki yekufambisa (ATS) LCD kuratidza haina chinhu. Iyo kamera yekuchengetedza yakakanganisika, uye chirongwa chevhidhiyo kubva kuiyo microwave link haina chinhu.
Kuita kuti zvinhu zvinyanye kuoma, apo simba rekushandisa radzoreredzwa, maAT anoputika. Kuti isu tirambe tichimonera, ndakamanikidzwa kuchinja maan. Iko kurasikirwa kurasikirwa kunodarika madhora zviuru zvishanu.
Zvinoshamisa, iyo Lea matatu-chikamu 480v Surge Dziviriro inoratidza hapana zviratidzo zvekushanda zvachose. Izvi zvakamutsa kufarira kwangu nekuti chinofanira kuchengetedza zvese zvishandiso munzvimbo kubva pane zviitiko zvakadaro. Nomufaro, transmitter yakanaka.
Iko hakuna zvinyorwa zvekuiswa kwegadziriro yekuvhara, saka ini handikwanisi kunzwisisa hurongwa kana tsvimbo yakavapo. Sezvazvinogona kuoneka kubva kumufananidzo 1, ivhu pane saiti rakaonda kwazvo, uye vakasara vevhu pazasi rakagadzirwa nedombo rechisimba, senge sica-based insulator. Mumatunhu ano, matanda akajairwa haafanire kushanda, ini ndinofanira kuona kana vakaisa tsvimbo yemakemikari uye kuti ichiri muhupenyu hwayo hunobatsira.
Kune zvakawanda zviwanikwa nezve pasi rekudzivisa kupokana kuyerwa paInternet. Kuita izvi zviyero, ini ndakasarudza iyo flukes 1625 yekupokana kwemamita, sezvakaratidzwa mumufananidzo mita Kuwedzera kune izvi, pane zvinyorwa zvekushandisa, izvo vanhu vanogona kutevedzera zviri nyore kuwana mibairo yakarurama. Uyu ndiwo mita anodhura, saka isu takarasikirwa mumwe kuti tiite basa racho.
Nyanzvi yeBreamCast mainjiniya vakajaira kuyera kupokana kwevaridzi, uye kamwe chete, tichawana kukosha chaiko. Kudzikisira kwepasi kwakasiyana. Zvatinotsvaga ndiko kuramba iko kuti ivhu rakapoteredzwa rinopa kana kuhukura kwazvino.
Ini ndakashandisa nzira ye "inokwanisa kudonha" paunenge uchiyera kuramba, dzidziso yeiyo inotsanangurwa mumufananidzo 1 uye nhamba 2. 3 kusvika ku5.
Mumufananidzo 3, pane iyo danda repasi e yeiyo yakakoshwa yakadzika uye pile c ine imwe chete kubva pasi yeruvhu E.
