I te mea he whakangahau, kua roa e akiakihia ana te reo irirangi runaruna ki te whakamatau i nga mea katoa kei a koe.I te wa e hiahia ana a [Tom Essenpreis] ki te whakamahi i tana antenna 14 MHz i waho o tana awhe auau hoahoa, i mohio ia kei te hiahia ia ki tetahi ara iahiko whakahoa.Ko te momo tino noa ko te ara iahiko L-Match, e whakamahi ana i nga purihiko taurangi me nga inductors taurangi hei whakatika i te awhe auau (resonance) o te antenna.Ahakoa he koretake i roto i etahi whirihoranga motuhake, he pai ki te tarai i te aputa i waenga i te 50 ohm impedance o te reo irirangi me te impedance unknown o te antenna.
Ma te kore e kore, i rapua e [Tom] etahi waahanga kei roto i tana ipu para, ma te whakamahi i nga rakau ferrite, te kapia wera, te waea aukume, te rīpene parahi me etahi atu 60 ml syringe mai i te reo irirangi AM hei whakahiato i nga pūnga iahiko rereke me nga whakauru.Tahi.Ka taea e koe te kite i a ia e huri ana i te pokapū o te pupuhi kia whai waahi mo te rakau ferrite.Takahia te waho o te syringe ki te waea hiko, ka taea te whakarite i te ferrite e te plunger, a ka taea te whakarereke i nga ahuatanga o nga waahanga ki te whakatika i te ara iahiko.I kii mai a [Tom] ka taea e ia te whakamahi i tana tuner hou i hangaia mo te rere ora, a, e mohio ana matou he pai ki a ia ki te whakamahi i ana taputapu hanga.
Ki te kore koe e pai ki te reo irirangi runaruna, tera pea ka taea e matou te kukume i a koe ki tenei roketi-a-hiri, he perehi perehi 3D kua peia e te syringe, he dragster peia-a-ringa ranei.Kei a koe ano to hacker hei tiri?Ahakoa he aha, tukuna ki te raina tere!
Ehara ahau i te HAM, kaore au i te tino mohio mo te HF, engari e mohio ana ahau kei etahi roopu auau, ka nui pea te mana TX, na reira ka nui te ngaohiko i runga i te antenna.He mea pai pea te whakauru i tetahi ngongo kirihou kore-whakahaere kua whakakiia ki te hau i waenga i te antenna tuner me te taputapu whakahaere?
I whakahuahia e ia etahi take e pa ana ki te koretake, ehara i te mea he raru.Kei te maumahara ahau i roto i te pukapuka na Doug Demaw i kii ia ka rite te ahua o nga ferrites ki te hau i nga iarere teitei ake.
I whakamahia e ahau he rakau ferrite i roto i te tuku pokiha 80m (3.5MHz).Ka whakaritea ki te ranunga ferrite o te auau e tika ana, ko te mate kei te awhe o te 5 dB.
He aha tenei waea hiko o Amerika e kitea ana e au i runga i te Ipurangi, he aha te hononga ki nga aukume?He mea hanga ki te rino?
Ko te waea aukume he waea parahi me tetahi paparanga enameled angiangi.Ki taku whakaaro he penei te whakaingoatanga na te mea ka whakamahia te nuinga ki te hanga i nga porotaka hiko, ara, mo nga awhi motopaika/koikoi reo orooro/solenoids/whakauru hiko/etc.
Mena karekau he syringe, ka taea te whakamahi i etahi mea corflute/coroplast hei porowhita o mua ka kuhu te ferrite ki roto.Mo nga taipitopito, tirohia: https://www.youtube.com/watch?v=NyKu0qKVA1I
