Mafupipafupi ang'onoang'ono amabwera ndi zolakwika zazikulu, mwachitsanzo, ngati mukutumiza ma transmitter a FM okhala ndi ma frequency osiyanasiyana kuyambira 88 mpaka 108Mhz, ndiye kuti mita yamagetsi ya 85-110Mhz RF ndiye chisankho chanu chabwino.

 

Ngati nthawi zambiri mumagwiritsa ntchito mita yamagetsi ya RF ya 1-200Mhz kuti mutumize chowulutsira cha FM, ndiye kuti cholakwika chake chidzakhala chachikulu kuposa mita yamagetsi ya RF yokhala ndi ma freq ang'onoang'ono. Zitha kuyambitsa zovuta monga zolongosoka zotulutsa mphamvu za transmitter ndi mlongoti wa VSWR.

 

#3 Pangani Commissiong kukhala Yosavuta kudzera pa APP Monitoring

 

Kusankha mita yamagetsi ya RF yokhala ndi kuwunika kwa APP kungakuthandizeni kusunga nthawi. Mitundu yamagetsi yamtundu wa RF iyi imapereka chiwonetsero cha digito ndi ntchito yojambulira nthawi. Kuyang'ana kwambiri pakutumiza chotumizira ndi mlongoti zonse zatsala kuti zichitike, palibe chifukwa chojambulira VSWR ndikupititsanso mphamvu zamagetsi m'buku! Mukudziwa zomwe izi zikutanthauza ku ntchito yanu.

 

#4 Osasiya Katundu Wawo Kumbuyo. 

 

Mamita amagetsi a RF okhala ndipamwamba kwambiri nthawi zambiri amakhala ndi moyo wautali wautumiki - amatsimikiziranso kulondola kwa kutumiza kwanu. Kuphatikiza apo, kapangidwe kolimba kamapereka chitetezo chokulirapo kuti amasule mita yamagetsi kuchokera pamabampu mumayendedwe ndi kayendedwe. Chifukwa chake, nthawi zonse samalani zamtundu wake musanayike oda ya mita yamagetsi ya RF. 

 

#5 Freq Selective kapena Freq Fixed Type

 

Ndizofunikira kudziwa kuti ma RF magetsi mita amatha kusankha pafupipafupi kapena kukhazikika, kusiyana kwakukulu pakati pa ziwirizi ndikulondola komanso mtengo.

 

Mwachitsanzo, mita yonyamula mphamvu ya RF yochokera ku Mbalame imatha kukwaniritsa zoyeserera zamagawo osiyanasiyana osiyanasiyana (monga 450kHz-2.7GHz kapena 50-100MHz, ndi zina zotero) ndi magawo amagetsi (monga 100mW-10kW) kudzera pakufananitsa mphamvu za pulagi zigawo.

 

Komabe, mtengo wake ukhoza kufika madola masauzande ambiri. 

 

Kwa owulutsa ambiri, mitengo yochulukira yogulitsa, kuchuluka kwa ma frequency, ndi kuchuluka kwamagetsi nakonso sikofunikira, osanena kuti zotsatira zoyesa zimakhala ndi zolakwika zazikulu (ngakhale zolondola zomwe akuti ndi ± 5%).

 

Poyerekeza ndi kuchuluka kwa ma frequency ndi kuchuluka kwa mphamvu zakale, mita yamagetsi ya RF yosankha pafupipafupi imakhala ndi mayeso apamwamba kwambiri ndipo nthawi zambiri imakhala yotsika mtengo. 

 

Mitundu yamagetsi yamtundu wa RF iyi ndi yapadera Imagwiritsidwa ntchito kuyang'anira kutulutsa kwamagetsi a RF ndi mtengo wa VSWR wa band ya ma frequency a FM, yomwe ilinso yokwanira kukwaniritsa njira zopatsira mawayilesi ambiri amphamvu kwambiri a FM.

 

Za FMUSER

 

FMUSER ndiye mtsogoleri wotsogola padziko lonse lapansi wamayankho otsika mtengo. Kuyambira 2004, tapereka bwino masauzande a mayankho odalirika a AM, FM, ndi ma TV m'maiko angapo padziko lonse lapansi, kuphatikiza mapaketi athunthu, upangiri woyika patali/pamalo, ntchito zodalirika zogulitsa, ndi zina zambiri.

 

 

Fakitale yathu yopangira zinthu imawonetsetsa kuti zida zonse zizigwira ntchito bwino kwambiri ndipo mpaka pano zapatsa wayilesi ya kasitomala aliyense wa FMUSER mphamvu zatsopano.

 

"Timayesetsa kuwonetsetsa kuti mumadziwa, ili ndi ntchito ya FMUSER"
