CB Radio - Unofanira Kuishandisa Nhasi? Ndezvipi zvakanakira CB radio?

Kuwanikwa kwakapararira kwemafoni uye isina waya internet kwave kureva kuti CB radio yakatsiviwa nefoni maapplication. Zvisinei, kuchine vatyairi (kunyanya avo vanowanzotyaira madaro marefu) vanoramba vakavimbika kuchisarudzo ichi. Zvakakodzera kutenga mudziyo wakadaro? Nzira yekuvamisa sei? Dzidza zvakawanda nezveCB Antennas!

CB antennas uye kutanga kwekutaurirana pasina waya

Pamwe munhu wese muhupenyu hwake akanzwa nezve walkie-talkies. Vana vainyanya kufarira kutamba nemidziyo iyi, asi handiyo yega mashandisirwo echigadzirwa ichi. Nei tichizvitaura? Mugadziri wayo akagadzirawo CB radio (inonzi "CB radio"). Uyu ndiAlfred Gross, anonyanya kufarira zvigadzirwa zvinoenderana nekutaurirana pasina waya. Mhinduro dzaakapa patent dzakaratidza kutanga kwenguva nyowani mumunda wekutaurirana pasina waya.

Antenna uye CB inogamuchira - iyo kit yekutaurirana inoshanda sei?

Iwo akanyanya kukosha ma paramita anoita kuti CB radio ishande ndeiyi:

• modulation;
• frequency.

Yekutanga yeiyi inogona kukamurwa kuita AM uye FM modulation. Musiyano mukuru pakati pezviviri imhando yechiratidzo. Ichave yakapfava zvakanyanya mumhando yeFM.

Frequency, kune rumwe rutivi, ndeye electromagnetic masaisai emhando dzakasiyana. Nekushanda kwechigadzirwa chekufambisa motokari munyika yedu, 40 chiteshi chakachengetwa, chiri pakati pe26,960 MHz kusvika 27,410 MHz. Mukati, akanga akakamurwa ndokuiswa chiratidzo maererano nemipimo inogamuchirwa. Kutenda kune izvi, kutaurirana kwakarongwa.

CB redhiyo - inodiwa midziyo

Kubva pakuona kwehunyanzvi hwekuona, zvinotevera zvinodikanwa pakushanda kwakaringana kwemachina:

• antenna;
• receiver (redhiyo runhare).

CB antennas anowanikwa mune akasiyana magadzirirwo uye kureba. Pane mutemo wakareruka: iyo yakareba antenna, iyo yakakura huwandu hwechiratidzo iyo inogona kugadzirisa. Nekudaro, kiyi ndeyekuita kuti zvese zvigadziriswe, nekuti pasina iyo, iyo CB radio, kunyangwe ine antenna refu, haishande nemazvo.

Mutungamiri, Midland Alan, Yosan - vagadziri vevanogamuchira CB

Kune akati wandei anotungamira vagadziri mumusika wemotokari wekutaurirana. Izvi zvinosanganisira kunyanya:

• Midland Alan;
• Albrecht;
• M-Tech;
• Pni;
• President;
• Lafayette;
• Yosan.

Chinokosha chekushanda kwechigadzirwa ndechekugadzirisa kwayo, asi kwete chete. Izvo zvakakoshawo zvakanyanya kuve neiyo yekudzikisa ruzha system, yekuwedzera majoini uye kushanda muAM kana FM modulation.

CB radio antennas - akajairika kureba

Iwe unotoziva kuti kune yakakura huwandu, iwe unofanirwa kutsvaga iyo yakareba kwazvo inogoneka antenna. Nekudaro, redhiyo yeCB ine antenna yakareba 150 cm inogona kuita kuti kutyaira kweguta kuve basa chairo. Zvisarudzo zvekutanga zviri muhupamhi hwemasendimita 60-130. Kune zvakare maantenna anoshanda akawanda, ayo ane basa rekugamuchira chiratidzo cheredhiyo, yemaoko-isina kit (microphone) uye yekushanda kweCB radio. Kazhinji ivo vanenge 50 cm kureba.

CB radio antenna - kukwira sarudzo

Unogona kusarudza imwe yenzira mbiri dzekuisa iyo CB antenna mumotokari yako:

• magnetic;
• nguva dzose.

Yokutanga inowanzosarudzwa nevatyairi nekuda kwekufamba. Padenga remotokari kana mune imwe nzvimbo yemuviri wakadzikama, iwe unofanirwa kuisa magineti base uye iyo iyo antenna yakasungirirwa. Nenzira iyi, redhiyo yeCB inogona kuunganidza zvikwangwani zvakatsiga. Imwe sarudzo ndeye mamodheru akaiswa zvachose mumotokari. Nekudaro, iyi mhinduro ndeyevatyairi vakatsunga vasingade kubvisa antenna kubva mumotokari.

Nzira yekusarudza CB antennas yeredhiyo?

Kuwedzera kune aya maficha, akati wandei mamwe ma paramita akakosha. Usati watenga, ita shuwa kuti mhando iyi ine mhando ipi. Sezvo mutemo, kune guta, makopi ediki madiki akakwana, anokwanisa kuunganidza chiratidzo mukati meiyo radius ye5 makiromita. Imwe nyaya ndeye antenna kuwana (yakayerwa mudBi). Kazhinji antenna ane iyi parameter muhuwandu kubva ku +1 kusvika +6 dBi. Zvechokwadi, zvakanyanya nani. Chimwe chinhu chinokosha kucherechedzwa ndicho chinhu chacho. Chinangwa chezvikamu zvesimbi isina tsvina. Vachave vanonyanya kupikisa kune unyoro.

CB radio - chii chekutenga mumotokari

Bet pamuenzaniso wekugamuchira wakaedzwa nevamwe vashandisi. Usangoteedzere pfungwa dzakatumirwa muzvitoro zvepamhepo, asi zvakare tsvaga ruzivo mumaforamu epamhepo. Iyo CB radio yaunoda kutenga (kunze kwekunge iri kopi yakachipa kubva kuMabvazuva) inotsanangurwa nemazvo nevashandisi. Batidza ASQ kudzikisa ruzha uye RF kuwedzera. Neaya maficha, iwe unozokwanisa kubvisa ruzhinji rwekumashure ruzha uye hurukuro. Iwe haudi chaizvo midziyo yepamusoro. Tarisa zvakare modhi ine NB/ANL sarudzo yekubvisa ruzha kubva pamagetsi emotokari.

CB Radio - AM kana FM?

Muchirevo chekusarudza anogashira, zvinodikanwa zvakare kuti upindure mubvunzo nezve rudzi rwemodulation. Pakutanga, takataura kuti mamodheru akashongedzerwa neFM modulation rutsigiro anofambisa chiratidzo che "chene". Nekudaro, munyika yedu, kunyanya AM makopi anotengeswa, uye mamwe acho anotsigira FM. Kana iwe uchingotyaira mudzimba, redhiyo yeCB AM inokwana. Nekudaro, kune nzendo dzenguva dzose kunze kwenyika, FM modulation inogona kudikanwa.

Maitiro ekuseta antenna yeCB?

Kugadziriswa kweiyo modhi kunofanirwa kufunga nezve chaiyo mota uye nzvimbo yegungano. Naizvozvo, mafoni anobviswa antenna haashande nguva dzose kana nzvimbo yavo yakashandurwa zvakanyanya. Rangarira kuve ne SWR mita iri nyore uye woibatanidza kune anogamuchira. Iyo redhiyo yeCB inofanirwa kucheneswa kure nemagetsi emagetsi akakwira. Ndeapi matanho andinofanira kutora kuti ndive nechokwadi chekuti mudziyo wakamisikidzwa nemazvo?

CB radio - nhanho nhanho chiteshi calibration

Pazasi, mundima shoma, tinopa nzira yepasirese yekuenzanisa redhiyo yeCB.

1. Gadzirisa antenna uye inogamuchira mumotokari. Vagadzirise sezvavanozomhanya zuva nezuva.
2. Batanidza SWR mita.
3. Gadzirisa redhiyo kuchiteshi 20 (inoshandiswa kugadzirisa).
4. Sarudza iyo FWD sarudzo pamamita.
5. Dzvanya uye ubate chinzvimbo chekutumira pane CB redhiyo girobhu.
6. Isa mita kune SET chinzvimbo.
7.  Chinja sarudzo pamamita kubva paFWD kuenda kuREF.
8. Uchiri kubata bhatani rekutumira, tarisa kukosha kunoratidzwa pachiratidzo (chaizvo pakati pe1 ne1,5).
9.  Edza kukosha pachiteshi 1 uye 40 - iwe unofanirwa kuwana kuverenga kwakanyanya pamakumi maviri.
10. Ready!

Kuita kweredhiyo yeCB kunoenderana nerudzi rweanogamuchira, kureba kweantenna, uye calibration chaiyo. Kwenzendo refu kunze kweguta, sarudza antenna refu. Kuguta, izvo zvinokwana masendimita 100. Yeuka kuti haufaniri kutenga zvigadzirwa zvinodhura, asi kuderedza ruzha kunokosha. Nekuda kweizvi, chiratidzo chichava chemhando yepamusoro.
