No ke aha e koho ai i ka STL-10 STL Transmitter a me ka mea loaʻa no ka Radio Radio FM?

No ke aha ʻo STL-10 Studio Transmitter Link Lako?

ʻO STL10 Studio i ka Transmitter Link / Inter-city Relay kahi ʻōnaehana kamaʻilio VHF / UHF FM e hāʻawi ana i kahi kaila leo hoʻolaha kiʻekiʻe me nā ʻano hui koho. Hāʻawi kēia mau ʻōnaehana i ka hōʻole ʻana i ke keakea, ʻoi aku ka maikaʻi o ka hana walaʻau, ʻoi aku ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, a me ka redundancy ʻoi aʻe ma mua o nā ʻōnaehana STL composite i kēia manawa.

He aha kāu e ʻike ai e pili ana i ka Link Transmitter Studio

Hoʻouna i kahi loulou studio-transmitter (a i ʻole STL) i kahi lekiō a i ʻole ke kelepona a ke kīwī pūnaewele a i ʻole ka leo o ka lekiō mai kahi kikowaena iʻike ai i ka lekiō a i ʻole ka mea kaha uila e hele ai ma kahi o nā wahi ʻē aʻe.

Pono pinepine kēia no ka mea ʻo nā wahi maikaʻi loa no kahi antenna aia ma luna o kahi mauna, kahi e koi ʻia ai kahi hale kiaʻi pōkole loa, akā ma kahi ʻaʻole kūpono ʻole kahi studio. ʻOiai ma nā ʻāina palahalaha, ʻaʻole kokoke ke kikowaena o ka wahi i ʻae ʻia e ke kikowaena ma kahi o ka studio a i ʻole i loko o kahi lehulehu kahi e ʻike ʻia ai ka transmitter e ke kaiāulu, no laila pono ke kau ʻia ka antenna i mau mile a mau mile paha.

Ma muli o nā wahi e pono e hoʻopili ʻia, hiki i kahi kikowaena ke koho i kahi loulou point-to-point (PTP) ma kekahi radiofrequency kūikawā a i ʻole kahi loulou uea uila hou aʻe ma o ka laina T1 a i ʻole E1 (a i ʻole ka mana nui). Hiki i nā loulou lekiō ke kikohoʻe, a i ʻole ke ʻano analog kahiko, a i ʻole ka hybrid o nā mea ʻelua. ʻOiai ma nā ʻōnaehana analog-analog kahiko, hiki ke hoʻouna ʻia nā leo leo a me ka ʻikepili me ka hoʻohana ʻana i nā subcarriers.

Nā Pōmaikaʻi ʻAʻole hiki iā ʻoe ke pale aku

• Hana ʻia mai 220 a 260MHz, 300 a 320MHz, 320 a 340MHz, 400 a 420MHz a me 450 a 490MHz
• Hiki ke hoʻonohonoho maʻalahi ʻia ka alapine i hoʻouna ʻia a loaʻa e ka ʻaoʻao mua kikohoʻe
• He kūpono no ka leo kikohoʻe. Hoʻomalu ʻia ka subsonic over modulation a me ka haʻahaʻa haʻahaʻa haʻahaʻa e kahi kaapuni manaʻo i mea e hoʻokiʻekiʻe ai i ka leo leo o nā ʻōnaehana kamepiula hou loa.
• Haʻahaʻa THD distortion: ʻo ka waiwai THD me ka stereo a i ʻole ka mono demodulate a me nā hōʻailona deemphasized he mea ʻole.
• Pane alapine paʻa: ma muli o ka ʻenehana hou loa a me ka pololei o ka ʻāpana i ka palahalaha o ka pane alapine.
• ʻO ka walaʻau haʻahaʻa: ʻo ka lākiō hōʻailona-a-noise maikaʻi loa ma ka mono a i ʻole ka stereo e hiki ai ke hoʻohana i kēia STL i nā pūnaewele multi-hop me ka hoʻohaʻahaʻa ʻole i ka maikaʻi o ka leo.
• ʻO ka ʻike kiʻekiʻe: hiki iā ia ke hōʻemi i ka hoʻopukapuka antenna o STL.
• ʻO ka palekana RF nui: hiki ke hana i ka nui o nā kaiapuni RF.
• ʻO ka hōʻole ʻana i ke kahawai pili kiʻekiʻe: loaʻa ka mahalo i ka pale mechanical maikaʻi loa a me ka pololei o ka kānana RF.
• ʻO ke kūpaʻa kiʻekiʻe me ka ʻike aniani i uku ʻia i loko o ka wela o loko.
•  Hōʻike LCD hoʻohui: hoʻopau i ka diagnostic a me ke ana ʻana o nā hōʻike LCD panel mua.
• Hōʻike ʻike i hoʻohui ʻia a me nā mana pale: no nā ʻāpana hoʻouna āpau a me ka pale no ka hana ʻino.
