INCAZELO EJWAYELEKILE

1-1. ISINGENISO.

I-Hallicrafters Model HA-5 entsha iyicwecwe, eziqukethwe ngokwayo, i-Variable Frequency Oscillator (VFO) eklanywe esikhundleni sekristalu ukuze isetshenziswe nanoma iyiphi evamile, engu-80 kuya ku-2 wamamitha*, isidlulisi esingamfundanga sikhathi.

Ukusebenza kwe-Heterodyne plus voltagUkulawulwa kwe-tunable kanye ne-crystal oscillators kuqinisekisa ukuzinza okukhulu kwefrikhwensi. Isilinganiso sokushuna se-A30to1, ngokuhlangana nokudayela okukhanyisiwe okulula ukukufunda emuva okulinganiselwe ngokuqondile kufrikhwensi yokusebenza kwebhendi ngayinye, sinikeza ukulungiswa kwefrikhwensi okunembile.

Ukuze kube lula futhi kube lula ukusebenza, isilawuli esisodwa IVULA amandla bese sikhetha ububanzi obudingekayo bokuphumayo.

Iswishi yangaphambili yephaneli ye-CAL elula ivumela ukubonwa ngokushesha kwefrikhwensi yesidluliseli nomamukeli wesiteshi.

*Iyunithi, njengoba ihlinzekiwe, ayifaki amakristalu e-heterodyne amabhendi angamamitha angu-6 noma angu-2, Uma kufanele ukusebenza kunoma yiliphi lala mabhendi, amakristalu e-heterodyne angase athengwe futhi afakwe, Bheka kuhlu lwezingxenye zohlobo olulungile lwekristalu, imvamisa, nengxenye yenombolo.

UKUFAKA

3-1. UKUKHIPHA.

Ngemva kokuqaqa i-VFO, yihlole eduze ukuze uthole umonakalo okungenzeka wenzeke ekuhambeni. Uma kwenzeka umonakalo ubonakale, ngokushesha file isicelo esinenkampani yenethiwekhi esisho ubukhulu bomonakalo. Hlola ngokucophelela wonke amalebula okuthumela futhi tags ukuze uthole imiyalelo ngaphambi kokuwasusa.

3-2. INDAWO.

I-VFO ihlinzekwa ngekhebula lokuphumayo lama-intshi angu-30. Iyunithi kufanele ibekwe ukuze le ntambo ibe nobude obanele ukuze ixhume i-VFO nesidlulisi. Lapho uthola i-VFO, gwema izindawo ezifudumele kakhulu, Ukuze uthole umoya ofanele, vumela okungenani iyintshi eyodwa yokuvula phakathi kwengemuva le-VFO nodonga.

QAPHELA

Ikhebula lokukhipha amandla elisabalalisiwe liyingxenye ye-resonating capacitance ye-output stage. Ubude bale khebula akufanele buhluke uma kuzotholakala ukusebenza kahle kwe-VFO.

3-3. UMTHOMBO WAMANDLA.

I-Model HA-5 VFO iklanyelwe ukusebenza kusukela ku-105-volt kuya ku-125-volt, umjikelezo we-60, umthombo wamandla we-AC. Ukusetshenziswa kwamandla ngama-watts angama-30.

QAPHELA

Uma ungabaza ngomthombo wakho wamandla, xhumana nenkampani yangakini yamandla kagesi ngaphambi kokufaka intambo kagesi endaweni kagesi ye-AC. Ukuxhuma i-VFO emthonjeni wamandla ongalungile kungase kubangele umonakalo omkhulu kuyunithi futhi kuhilele ukulungiswa okumba eqolo.

3-4. UKUXHUMANA UHLELO OLUJWAYELEKILE.

Umugqa wetheminali onezikulufu ezimbili unikezwa ngemuva kwe-chassis ukuze kuxhunywe i-VFO ohlelweni lokulawula isiteshi. Bheka izibalo 2 no-3.

Kunikezwe ama-jack amabili ngemuva kwe-chassis ukuxhuma okukhiphayo kwe-VFO kusidlulisi. Ujeke owodwa usetshenziselwa ukuphuma kwamamitha angama-80 kuye kwayi-10, kanti enye ijekhi isetshenziselwa okukhiphayo okungamamitha angu-6 namamitha angu-2.

Uma inkinobho isendaweni ethi VALIWE, isekethe ye-VFO keying ibuyiselwa kumatheminali okhiye kuphinifa elingemuva lapho ingase ifakwe khona ukhiye wohlelo lokulawula isiteshi.

4-5. INKONZO KANYE IMIBUZO YOKUSEBENZA

Ukuze uthole ulwazi olwengeziwe mayelana nokusebenza noma ukusezwa kweyunithi, xhumana nomthengisi we-Hallicrafters ethengwe kuye. I-Hallicrafters Company igcina uhlelo olubanzi Lwezikhungo Zesevisi Ezigunyaziwe lapho noma iyiphi isevisi edingekayo izokwenziwa ngokushesha nangempumelelo ngenkokhiso encane.
Zonke Izikhungo Zesevisi Ezigunyaziwe ze-Hallicrafters zibonisa uphawu oluboniswe kwesokudla. Xhumana nomdayisi wakho noma incwadi yocingo ukuze uthole indawo eseduze nawe.

Ungathumeli isevisi efekthri ngaphandle kokuthi uyalelwe ukuba ukwenze lokho ngencwadi. I-Hallicrafters Company ngeke yamukele isibopho sanoma yikuphi ukuthunyelwa okungagunyaziwe.

I-Hallicrafters Company igodla ilungelo lokwenza izibuyekezo ekukhiqizweni kwamanje kwezisetshenziswa futhi ayithathi sibopho sokufaka lezi zibuyekezo kumamodeli angaphambili.

UKUSEBENZA

5-1. JIKELELE.

Setha iswishi ye-BAND SELECTOR uye ebhendini oyifunayo (lokhu futhi KUVULA amandla e-VFO). Vumela imizuzu embalwa ukuze iyunithi ifinyelele izinga lokushisa lokusebenza.

Uma isidlulisi sisekubekwe eceleni, shuna i-VFO kumafrikhwensi oyifunayo njengoba kukhonjisiwe odayelini olulinganiselwe. Uma uthanda, ungakwazi ukushaya ifrikhwensi yokwamukela kwakho ngokusetha inkinobho ye-CAL-OFF ibe yindawo ye-CAL. Lungisa isilawuli sokushuna se-VFO ukuze uthole ithoni ephansi kakhulu (okungukuthi, ibhithi eyiziro) njengoba kuzwakala kusipika sesiteshi. Uma lesi simo sikhona, imvamisa yokudlulisela iqondana ncamashi nemvamisa yomamukeli. Setha iswishi ye-CAL ukuthi IVALI.

Guqula iswishi yesidluliseli sibe yi-OPERATE futhi uqhubeke nenqubo yokushuna enconyiwe yabakhiqizi.

5-2. ISIKALI SOKUDAYELA.

Umfanekiso 5 ubonisa ukulinganiswa kokudayela kwe-Model HA-5. Izilinganiso zibonisa imvamisa yenkampani yenethiwekhi ye-transmitter okukhiphayo stage, hhayi okukhiphayo kwe-VFO. Ithebula elilandelayo libala amabhendi ayizimfundamakhwela, imvamisa yokuphuma kwe-VFO, kanye nokuphindaphinda okudingekayo ukuze kutholwe imvamisa yokuphumayo komthumeli oyifunayo.

Izikali zokudayela ezinkulu zebhendi ngayinye zihlukene ngo-100 KC. Ebhendini yamamitha ayi-10, amamaki okulinganisa amaphakathi anikezwa ngezikhathi ezingama-20-KC. Njengoba amaphuzu angu-100-KC kumabhendi angamamitha angu-80, 40, 20, kanye ne-10 ahambisana, ukulinganisa okumaphakathi kwamamitha ayi-10 kungasetshenziswa kulawa mabhendi. Kumamitha angu-80 no-40 amamaki amancane okulinganisa amamitha ayi-10 amelela u-5 KC futhi kumamitha angu-20, i-10 KC. Kumabhendi amamitha ayi-15, 6, kanye nama-2, amamaki okulinganisa amaphakathi anikezwa ngokuqondile ebhendini ngayinye.

Ukuze uthole ukufinyelela kumashubhu bese udayela u-lamps, susa i-chassis ekhabetheni (bheka isigaba 6-2). Indawo yamakristalu, amashubhu, kanye nokudayela lamp kuboniswe esithombeni 7.

6-2. UKUSUSWA KWE-CHASSIS.

I-chassis ingase ikhishwe kukhabhinethi ngokukhipha izikulufu ezine ezakha intambo kusukela phansi kwekhabhinethi. Lapho ususa i-chassis ekhabetheni, kufanele kuqashelwe ukuthi ungalimazi noma yiziphi izingxenye.

6-3. UKUDAYELA KABUSHA IKHODI.

Khipha i-chassis kukhabhinethi ukuze uphinde uhlukanise intambo yokudayela (bheka isigaba 6-2). Zungezisa isigubhu sokushuna ngokugcwele ngokwewashi (ukushuna amapuleti e-capacitor ane-meshed ngokugcwele). Kufanele kuqashelwe ukuthi ungalimazi amapuleti e-capacitor. Bheka umfanekiso wesi-6 ngenqubo yokuhlanganisa izintambo. Ukuphinda ucule ukudayela: bopha iluphu engasheleli engxenyeni eyodwa yentambo, namathisela le loop kusigubhu sokushuna endaweni A. Landela imicibisholo nokulandelana kwenombolo; qiniseka ukuthi intambo yenza iluphu eyodwa ephelele ezungeze isigubhu ngaphambi kokuya ku-control shaft. Gcina ukushuba okwanele entanjeni yokudayela ngesikhathi sokuhlanganisa ukuze uvimbele ukuthi ingasheleli esigubhini sokushuna, Bopha indawo ekhululekile yentambo yokudayela endaweni yokudayela ngefindo elingasheleli ukuze kuthi lapho isiphethu sinamathiselwe kusigubhu sokushuna endaweni engu-B sihlale sinwetshiwe cishe ngo-1/4 intshi.

UMBONO WOKUSEBENZA

I-Tube V1A (1/2 8U8A) iyi-oscillator eguquguqukayo eshuna i-5.0 MC kuya ku-5.5 MC. Uchungechunge olushuniwe inhlanganisela ye-C3 (i-tuning capacitor) kanye ne-L1 isetha imvamisa. I-C1A ne-C1B ama-capacitor anxephezela izinga lokushisa anikeza ukuzinza kwefrikhwensi yesikhathi eside.

I-Tube V1B (1/2 6U8A) iyi-crystal oscillator engashintshiwe edizayinelwe amakristalu ajwayelekile e-CR-18/U. I-BAND SELECTOR ikhetha ikristalu efanele yebhendi ngayinye.

Imiphumela yama-oscillator i-heterodyned ku-mixer, i-V2 (6BA7), ikhiqiza isamba kanye namafrikhwensi omehluko. I-transformer eshunwe kabili kupuleti le-minus (L2 kumamitha angu-80, i-L3 kumamitha angu-40 ukuya kumamitha angu-10, kanye ne-L4 kumamitha angu-8 namamitha angu-2) ikhetha ifrikhwensi efanele ye-heterodyned (crystal minus tunable) futhi inikeza okukhiphayo okungaguquki kakhulu ebangeni lemvamisa.

I-Tube V3 (BAQ5A) ampyenza isignali oyifunayo ibe sezingeni elanele ampi-litude yokushayela i-oscillator yokudlulisa noma i-buffer ampokokuphila.

I-Keying yenziwa ngokuvula ama-cathode circuits ku-mixer kanye nokuphumayo ampophi stages. Esimeni sokhiye, i-resistor R22 (47K ohm) ikhawulela ivolumutage ukunqamula amatheminali angukhiye ukuya ngaphansi kwamavolthi angama-40.

Ukunikezwa kwamandla kusetshenziswa i-transformer futhi kuqukethe ama-silicon rectifiers amabili axhunywe kumagagasi agcwele. I-Resistor R20 iyisivimbeli esikhawulela ukukhuphuka futhi, ngaphezu kwalokho, sisebenza njengefuse, sivikela izihlungi kanye ne-transformer uma kuba nefushana elingu-B+. I-Tube V4, i-OA2 gaseous regulator tube, inikeza ukulawulwa kwe-B+ kuwo womabili ama-oscillator.
