Nka kwishimisha, radio yikinira yashishikarijwe kugerageza ikintu cyose ushobora kuba ufite mukiganza. Igihe [Tom Essenpreis] yashakaga gukoresha antenne ye ya 14 MHz hanze yumurongo wateganijwe, yari azi ko akeneye uruziga ruhuza inzitizi. Ubwoko bukunze kugaragara cyane ni L-Umukino wumuzunguruko, ukoresha capacator zihindagurika hamwe nindobanure zihindura kugirango uhindure imirongo ikoreshwa (resonance) ya antene. Nubwo idakora neza muburyo bumwe bwihariye, nibyiza gukemura icyuho kiri hagati ya 50 ohm impedance ya radio no kutamenyekana kwa antenne.
Nta gushidikanya, [Tom] yashakishaga ibice biri mu myanda ye, akoresheje inkoni ya ferrite, kole ishyushye, insinga ya magneti, kaseti y'umuringa hamwe na siringi zigera kuri 60 ziva kuri radiyo AM kugira ngo ikusanyirize hamwe ubushobozi bwa kanseri. Twese hamwe. Urashobora kumubona asya hagati ya plunger kugirango abone umwanya wa ferrite. Kizingira hanze ya singe ukoresheje insinga ya electromagnetic, gahunda ya ferrite irashobora guhindurwa na plunger, kandi ibiranga ibice birashobora guhinduka kugirango uhindure uruziga. [Tom] yatangaje ko yashoboye gukoresha tuneri ye nshya yakozwe mu buryo bwa Live, kandi tuzi neza ko akunda gukoresha ibikoresho bye.
Niba udakunda radio yikinira, noneho birashoboka ko dushobora kugukurura hamwe na roketi ishingiye kuri syringe, ikoreshwa na siringi itwarwa na 3D icapura imashini, cyangwa vacuum syringe itwarwa na dragster. Ufite hacker yawe kugabana? Ibyo ari byo byose, shyira kumurongo wihuse!
Ntabwo ndi HAM kandi sinzi byinshi kuri HF, ariko nzi ko mubice bimwe byinshyi, imbaraga za TX zishobora kuba nini, bityo voltage kuri antenne izaba nini. Byaba ari ikintu cyiza gushyiramo umuyoboro wa pulasitiki udatwara ibintu wuzuye umwuka hagati ya tuneri ya antenne nigikoresho cyo kugenzura?
Yavuze ku bibazo bimwe na bimwe bijyanye no kudakora neza, ntabwo ari ikibazo. Ndibuka mu gitabo cyanditswe na Doug Demaw yavuze ko amaherezo ferrites yitwara nk'umwuka kuri radiyo nyinshi.
Nakoresheje inkoni ya ferrite muri 80m transmitter (3.5MHz). Ugereranije na ferrite ivanze yumurongo ukwiye, igihombo kiri murwego rwa 5 dB.
Nuwuhe mugozi w'amayobera w'amashanyarazi ya Amerika mbona kuri enterineti, kandi bihuriye he na magnesi? Yakozwe mu byuma?
Magnet wire ni insinga y'umuringa ifite urwego ruto rworoshye. Ndakeka ko yitiriwe ubu buryo kuko ubusanzwe ikoreshwa mugukora amashanyarazi ya electronique, ni ukuvuga, kuri moteri ya moteri / kuvuga amajwi ya coil / solenoids / inductors / nibindi.
Cyangwa, niba udafite syringe, ibintu bimwe na bimwe bya corflute / coroplast birashobora gukoreshwa nkigiceri cyambere hanyuma ferrite ikanyerera. Ushaka ibisobanuro birambuye, nyamuneka reba: https://www.youtube.com/watch?v=NyKu0qKVA1I
Ukoresheje urubuga na serivisi zacu, wemera byimazeyo gushyira ibikorwa byacu, imikorere hamwe na kuki yamamaza. wige byinshi
