Ehia mau alapine ka ʻokoʻa ma waena o ka ʻāpana V a me ka ʻāpana U o ka ʻāpana uea uila U a me ka ʻāpana V e hoʻohana i nā alapine lawe leo like ʻole. ʻO lākou a pau nā leki uila lekiō. ʻO ka hui UHF kahi hui pinepine kiʻekiʻe me ke alapine waena o 145 MHz a me kahi pae waena ma waena o 144.000-145.800 MHz, i hoʻohana ʻia ma ke ʻano he laʻa hoʻolaʻa no nā lawelawe amateur. ʻO ka hui VHF kahi kaha pinepine me kahi alapona waena o 435 MHz. ʻElua ʻāpana: 430.000-435.000 a me 438.000-440.000 MHz, i hoʻohana ʻia ma ke ʻano he lawelawe lua o ka lawelawe amateur a kaʻana like i nā band frequency me nā lawelawe ʻē aʻe. Kaawale mai ka ʻokoʻa, ʻaʻohe nīnau no ka mea ʻoi aku ka maikaʻi. ʻO ia wale nō ka hoʻohana ʻia ʻana o nā pae alapine e like me nā manawa hoʻohana ʻokoʻa a me nā koi. Aia ka ʻāpana U a me ka ʻāpana V i ke ʻano o ka nohona āu e hoʻohana nei. Pono e ʻōlelo ʻia he pono kā kēlā me kēia. Loaʻa i ka ʻāpana U kahi bandwīwī nui, ʻo ka ʻāpana U i ke alapine kiʻekiʻe, a me ke alapine waena waena V. I kēia manawa me ka hoʻomohala ʻana o ka ʻenehana, ʻoi aku ka nui o ka ʻoihana o ke kani ʻana o ke kani, e koi ana i kahi koho lōʻihi o V-band, a me ka U-band no nā koina e pono ai ke kani. ʻO kēia mau kaha pinepine i hoʻohana ʻia no nā microphone uea ʻole i loaʻa i kā lākou mau pono a me nā mea pono ʻole. Hoʻoholo ʻia kēia e ka mea hoʻohana i ke kaha pinepine, nā ʻano o ke kino o ka band frequency, a me nā palena hoʻoponopono o ka band frequency.

ʻO nā ʻāpana ʻelua o hoʻokahi-no-ʻelua mau microphone i ʻokoʻa nā alapine. Hoʻokaʻawale pū ʻia nā microphones e kūlike i nā kaha haʻahaʻa a me nā pae kiʻekiʻe pinepine a ʻaʻole hiki ke huikau. Hoʻokaʻawale pinepine ʻia kēia microphone U-band i nā kaha pinepine 3, ma ka maʻamau 680-740MZ. ʻO kēia kahi ʻāpana. 740-800M ka ʻāpana waena, 800-860 a i ʻole 890M ka ʻāpana kiʻekiʻe. Māhele ʻia nā microphone i ʻekolu mau ʻāpana. Ua kūʻai aku kaʻu ʻāpana he 26 mau seta o ʻekolu mau mana o nā microphone uea ʻole U-channel, e hana maʻamau nei i kēia ʻekolu mau ʻāpana U. i. No laila pono ʻoe e hoʻokaʻawale i nā microphones pae haʻahaʻa a me nā mea loaʻa haʻahaʻa, a ʻo nā ʻano ʻē aʻe nā mea loaʻa no 4 (ʻelua kiʻekiʻe a ʻelua haʻahaʻa), hoʻokahi no 8, a ua hālāwai wau me 1 no 8 no microphone uila ʻole i nā hālāwai. . No nā kaha pinepine 3, pono ʻoe e hoʻokaʻawale iā lākou a laila hoʻopili i nā kaha alapine. Kūlike ke ʻano pinepine pinepine o nā kahawai āpau, ʻaʻohe ʻokoʻa, kekahi me ka pinepine akomi infrared, hana hoʻokahi kī. Hiki ke hoʻonohonoho ʻia kēia ʻano microphone a me ka mea loaʻa e hōʻike i nā hōʻike ʻelua o ka helu kanal a me ke alapine ke hoʻonohonoho nei. Ke hoʻoponopono ʻoe i ke alapine hōʻike, he maʻalahi loa e hoʻopili i ke alapine. Inā like ka pinepine, OK. ʻAʻole pono e noʻonoʻo i ka helu o ke kahawai. ʻO kahi pilikia ʻē aʻe hiki ke hoʻololi ʻia ka waiwai decibel. Ke ʻokoʻa ka leo kani o nā microphone ʻelua, e nānā inā no ka like ʻole o ka helu decibel.
