Me ke kōkua o nā lolouila i puhi ai i keia la ke hoʻomaopopo i ka loa mau manao. Hoomaka ana nā pūnaewele enthusiast e hōʻiliʻili i ka ikaika, e hiki i na "mea lahaʻole" mea like me ka leo mīkini hana wāwahie. Keia mea ua ua hanaʻia ma luna o ka hanalima me ka unahiʻole, a ua papahana e hoʻopale ai i ka ike kulu mai ke hoʻohana mīkini uila no: kamepiula 'ē aʻe, lawe lima kaul, etc. Ua hoi pinepine i kapaia "jammers" no ka mea, o kona hiki, e uhi i kekahi 'ike neaiae, a moe loko o ka laulā o ko lākou mau hana.

E ho ohana o ka mea i pono i ka oihana a me keʻena hoʻokolohua, ma ka mau, ma kahi e noho ke kupaianaha mahuka. Inā kekahi hui he mea he pāpā ma ka hoʻohana 'ana o ka lawe lima kamaʻilio, ka halulu mīkini hana wāwahie mea hiki ke aeie kekahi hōʻailona, a pale aku ke kūkā'. Eia hou, e hiki ke hana i kekahi mea e, e paha pēlā-kapaia "keʻokeʻo halulu". Keia walaau He audible huahelu, i hiki ole i ke kulu o ka 'ike a me ka halawai noho pilikia ke kūkā' i. Room i ka mea ia manawa, "lāʻau malumalu ma keʻokeʻo leo."

Ma waho o ka luna examples, ka halulu mīkini hana wāwahie hiki ke hoʻohana 'ia no nā hana. Paha, he nui no ka kau mīkini "Battleship" ma i ka mea i pono, e kikeke mai i ka moku ka hoʻohana 'ana i ka torpedo. I ka injected i loko o ka pahuhopu ka loaʻa o ka walaau mīkini hana wāwahie, a hana ma o ka leo huahelu, a hoʻi me ka halulu ana o ka Naita.

Oia kekahi mea i mea e no? Ieoaeunoai, ina oe i ike i ka rula o ka hana. Ka mea hana ma ka leo huahelu, paha ke he hoailona kani alapine (frequency), like ikaika hawewe. A hiʻona o ka mea o ia ma ka auoiaea o ka hui neaiae mea i hiki mai ka poʻe. He hiki ia paha, e olelo aku, he iee?, Pololei mahele ana a me ka hoʻohuihui nā leo huahelu mau lepa a me ka maopopo xi. Akā, e ka nui maʻalahi e hoʻohana i ke kumu o ke keʻokeʻo halulu uilaʻoe: Radio paipu a me zener diode. Mau manao maalea i oluolu i loaʻa ma ka hana kūikawā papa kāwiliʻai. Zener halulu mīkini hana wāwahie ninoieo o parametric stabilizer. Ke neaiae Ua lawe 'ana mai o ka zener diode, a ua haawi mai ia i ka hana ana pahu hoʻonui leo me ka maopopo cutoff alapine (frequency). Penei kaʻawale keʻokeʻo halulu ua hoʻokāʻoi 'ia e nā leo Amp, a hele aku i ka'ōlelo. Ka mea hana stably ma ke ākea huahelu ka mahana, a hoʻomaka e paha i kekahi poʻe'ē he alapine (frequency) neaiaea koke ka piʻiʻana a me ka ai pili aku i ka mana kumu ma hope. Kokoke hana hoihoi i ka lohe ana i ka zener diode.

Makaukau i na mea maalea hiki no hoi ke kuai ma ka hale kūʻai. Me lakou i mea hoike, noonoo i ka halulu mīkini hana wāwahie GSH-1000M. Ke manaʻo Ua olelo hoopomaikai, a me kona kahahńnai o ka hana, he 40 kapuaʻi kuea mika. He i malama i ka hui e ku e kulu hiki ike mai kamepiula 'ē aʻe hana.
