Inkcazelo emfutshane:


Iinkcukacha zeMveliso

Iithegi zeMveliso

Iimpawu zenkqubo

Uluhlu lwamaza kanomathotholo: 645.05-695.05MHz (Itshaneli: 645-665, itshaneli B: 665-695)

I-bandwidth esebenzisekayo: 30MHz ngetshaneli nganye (60MHz iyonke)

Indlela yokumodareyitha: I-FM frequency modulation inombolo yesitishi: i-infrared automatic frequency ehambelana namatshaneli angama-200

Ubushushu bokusebenza: thabatha i-18 degrees celcius ukuya kuma-50 ngokukaCelsius

Indlela ye-Squelch: ukubhaqwa kwengxolo ezenzekelayo kunye nekhowudi ye-ID yedijithali

I-offset: 45KHz

Uluhlu lweDynamic: >110dB

Impendulo yomsindo: 60Hz-18KHz

Umlinganiselo obanzi wesignali ukuya kwingxolo: >105dB

Ugqweso olubanzi: <0.5%

Iimpawu zomamkeli:

Imowudi yokufumana: i-superheterodyne yokuguqulwa kabini, ulwamkelo oluyinyani lolwamkelo olwahlukileyo

Imowudi ye-Oscillation: isigaba se-PLL sitshixiwe loop

Ifrikhwensi ephakathi: i-frequency yokuqala ephakathi: 110MHz,

I-frequency yesibini ephakathi: 10.7MHz

I-antenna interface: isihlalo se-TNC

Imo yokubonisa: LCD

Uvakalelo: -100dBm (40dB S/N)

Ucinezelo olungamanga:>80dB

Imveliso yeAudio:

Ukungalungelelani: +4dB(1.25V)/5KΩ

Ibhalansi: +10dB(1.5V)/600Ω

Umbane wombane: DC12V

Ukunikezelwa kwamandla ngoku: 450mA

Iimpawu zokuhambisa: (908 ukuqaliswa)

Imowudi ye-Oscillation: isigaba se-PLL sitshixiwe loop

Amandla emveliso: 3dBm-10dBm (LO/HI conversion)

Iibhetri: 2x "1.5V No. 5" iibhetri

Okwangoku: <100mA(HF), <80mA(LF)

Sebenzisa ixesha (ibhetri ye-alkaline): malunga neeyure ze-8 kumandla aphezulu

Ukungasebenzi kakuhleunyango

iimpawu zokungasebenzi kakuhle

Iinkqubo zininziunobangela

Akukho nto ibonisa kumamkeli kunye nomthumeli

Akukho mandla kwi-transmitter, amandla owamkeli akaqhagamshelwanga ngokufanelekileyo

Umamkeli akanalo uphawu lweRF

I-receiver kunye ne-transmitter frequency bands zahlukile okanye ziphuma kuluhlu olwamkelekileyo

Kukho isignali yefrikhwensi yerediyo, kodwa akukho signali yesandi

Imakrofoni yokudlulisela ayidityaniswanga okanye i-squelch yomamkeli nayonzulu

Ukungasebenzi kakuhle kweesekethe zesikhokelo

Ukumisela imo ethi cwaka

Ingxolo yomqondiso wesandi ongasemva inkulu kakhulu

Ukutenxa kwi-modulation frequency kuncinci kakhulu, ukufumana imveliso yombane Inqanaba liphantsi, Okanye kukho umqondiso wokuphazamiseka

Ukugqwetheka kophawu lomsindo

Thumelaterukutenxa kwimodulation frequency nakoenkulu, imveliso yomamkeli Inqanaba lombane likhulu kakhulu

Umgama wokusetyenziswa umfutshane, umqondiso awuzinzile

Amandla okuseta umthumeli aphantsi, kwaye i-squelch yomamkeli inzulu kakhulu.

Ukusetha okungafanelekanga kwe-eriyali yomamkeli kunye nokuphazamiseka okuqinileyo kwebhetri ngeenxa zonke.
