A matsayin abin sha'awa, an daɗe ana ƙarfafa rediyon mai son yin gwaji da duk wani abu da kuke da shi a hannu. Lokacin da [Tom Essenpreis] ya so ya yi amfani da eriyarsa na 14 MHz a waje da kewayon ƙirar ƙirar sa, ya san yana buƙatar da'ira mai dacewa da impedance. Nau'in da aka fi sani shine da'irar L-Match, wanda ke amfani da madaidaicin capacitors da inductor masu canzawa don daidaita kewayon mitar mai amfani (resonance) na eriya. Kodayake rashin inganci a cikin wasu ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun bayanai, suna da kyau wajen daidaita tazarar da ke tsakanin 50 ohm impedance na rediyo da kuma rashin sanin eriya.
Ba tare da shakka ba, [Tom] yana neman sassa a cikin kwandon shara, ta amfani da sandunan ferrite, manne mai zafi, waya magnet, tef ɗin jan ƙarfe da wasu ƙarin sirinji na 60 ml daga rediyon AM don harhada masu iya canzawa da inductor. Tare. Za ka iya ganin shi ya nika daga tsakiyar plunger don ba da sarari ga sandar ferrite. Kunsa waje na sirinji tare da waya na lantarki, ana iya daidaita tsarin ferrite ta hanyar plunger, kuma za'a iya canza halayen abubuwan da aka gyara don daidaita yanayin. [Tom] ya ba da rahoton cewa ya sami damar yin amfani da sabon saƙon sa don yawo kai tsaye, kuma mun tabbata yana son yin amfani da ingantaccen kayan aikin sa.
Idan ba ku son rediyo mai son, to wataƙila za mu iya jawo hankalin ku da wannan roka na tushen sirinji, bugu na 3D bugu na sirinji, ko mai jan-kore sirinji. Kuna da hacker naku don rabawa? A kowane hali, ƙaddamar da shi zuwa layin gaggawa!
Ni ba HAM ba ne kuma ban san da yawa game da HF ba, amma na san cewa a wasu rukunin mitar, ƙarfin TX na iya zama babba, don haka ƙarfin lantarki akan eriya zai yi girma. Shin zai iya zama abu mai kyau don shigar da bututun filastik mara amfani da ke cike da iska tsakanin madaidaicin eriya da na'urar sarrafawa?
Ya ambaci wasu batutuwa game da rashin aiki, wanda ba shi da matsala. Na tuna a cikin wani littafi na Doug Demaw cewa ya yi iƙirarin cewa ferrites a ƙarshe suna zama kamar iska a mafi girma.
Na yi amfani da irin wannan sandar ferrite a cikin 80m fox transmitter (3.5MHz). Idan aka kwatanta da cakuda ferrite na mitar da ta dace, asarar tana cikin kewayon 5 dB.
Menene wannan baƙon igiyar wutar lantarki ta Amurka da nake gani akan Intanet, kuma menene alaƙarta da maganadisu? An yi shi da karfe?
Wayar Magnet waya ce ta tagulla wacce ke da sirin insulating enameled Layer. Ina tsammanin ana kiranta ta wannan hanyar ne saboda yawanci ana amfani da ita don yin coils na lantarki, wato, don motsin motsi / lasifikar murya / solenoids / winding inductor / da sauransu.
Ko kuma, idan ba ku da sirinji, za a iya amfani da wasu kayan corflute/coroplast azaman coil tsohon kuma ferrite ya shiga ciki. Don cikakkun bayanai, da fatan za a duba: https://www.youtube.com/watch?v=NyKu0qKVA1I
Ta amfani da gidan yanar gizon mu da sabis ɗinmu, kun yarda a sarari ga sanya ayyukanmu, ayyuka da kukis ɗin talla. kara koyo
