Ntau yam kho qhov ntau ntawm cov teeb liab ua tau zoo tso tawm thiab Offset txav uas nce lossis nqis.

Kauj Ruam 7: Mloog Xov Tooj Cua Xov Tooj Cua

Muaj cov plugins tso cai rau SDR# txiav txim siab ntau yam sib txawv ntawm kev tshaj tawm tab sis nws tuaj yeem ua si AM thiab FM xov tooj cua tshaj tawm hauv lub thawv.

Hauv lub vaj huam sib luag sab laug, qhib lub Xov tooj cua pab pawg. Koj tuaj yeem xaiv ib ntawm 8 hom sib txawv ntawm kev tshaj tawm los txiav txim siab. Qhov muaj txiaj ntsig tshaj plaws yog AM rau kev tshaj tawm AM ib txwm muaj, thiab WFM rau tshaj tawm (dav-band) FM tshaj tawm.

(Koj tuaj yeem paub txog qhov sib txawv ntawm nruab nrab ntawm AM thiab FM hauv Restart Wiki hauv Cov Xov Tooj Ua Haujlwm Li Cas.)

Xaiv qhov koj xav tau thiab qhib lub xov tooj cua. Lub suab yuav tsum tawm ntawm koj lub khoos phis tawj tham.

Lwm hom yog siv los ntawm xov tooj cua ham thiab cov kev pabcuam xws li cua-qhab.

Whereas nrog AM ib txwm nws yog qhov yooj yim heev rau rho tawm lub suab txawm tias muaj qee yam yooj yim xws li teeb tsa siv lead ua, nws tsis muaj txiaj ntsig nyob rau ob qho kev xa hluav taws xob thiab bandwidth. Hauv lub zog, vim tias muaj tus neeg nqa khoom ntau zaus ib txwm raug xa tawm txawm tias thaum nyob ntsiag to hauv kev tshaj tawm. Yog li vim li cas ho tsis cia li txwv tus neeg nqa khoom? Thiab hauv kev siv bandwidth vim tias lub suab tau nthuav tawm qhov sib npaug ntawm ob sab ntawm cov neeg nqa khoom zaus hauv ob "sidebands". Yog li vim li cas ho tsis txwv ib sab tes? Ua ob qho tib si, txhua lub zog xa hluav taws xob mus rau hauv kev xa cov ntaub ntawv (lub teeb liab) kom muaj txiaj ntsig zoo li sai tau, thiab yog li kev tshaj tawm yuav mus ntxiv.

SDR# txhawb nqa txhua qhov sib txawv ntawm cov no. DSB yog Ob Sab Sideband, qhov twg tsuas yog tus neeg nqa khoom raug txwv. LSB thiab USB qis dua thiab Upper Sideband, qhov chaw sab saud lossis qis dua (feem) kuj tseem raug txwv. Tsis muaj ib qho ntawm no tau siv rau kev tshaj tawm ib txwm muaj vim tias yuav tsum tau txais cov lus nyuab dua thiab yuav tsum tau kho kom raug kom tsis txhob muaj qhov txawv txav loj vim tus neeg txais yuav tsum rov tso cov neeg nqa khoom ntawm qhov tseeb.

CW yog Kev Nruam Ntiag Tug yog siv rau Morse code. Tus xa tawm tsuas yog qhib thiab tawm thiab SDR# yuav tsim cov cim thiab cov cim ua luv li cov ntawv luv thiab ntev.

NFM yog nqaim-qhab FM. Txog cov kev pabcuam uas tsis muaj qhov zoo yuav tsum tau tsuav yog cov lus txawj ntse tuaj yeem sib kis tau, FM tuaj yeem tshaj tawm tau siv ntau qhov bandwidth tsawg dua. Qhov no tso cai rau ntau txoj hauv kev kom tau ntim rau hauv qhov ntau ntawm cov zaus.

Kauj Ruam 8: Tshawb xyuas 433MHz Gadgets

433MHz yog siv rau kev sib txuas lus luv luv los ntawm tus tswv ntawm cov khoom siv hluav taws xob qis nrog rau lub tsheb fobs tseem ceeb, lub mloog pob ntseg wireless, lub qhov rooj tswb wireless, lub tsev tsis siv neeg thiab cov khoom ruaj ntseg thiab cov huab cua hauv tsev. Nws yooj yim heev los khaws cov no thiab tso saib lawv siv rtl_433.

Siv koj lub tshuab tshawb fawb uas koj nyiam tshaj, tshawb rau lub Windows rtl_433, lossis tshawb rau qhov txuas no:

cognito.me.uk/computing/windows/2015/05/26…

Hauv qab kab ntawv rub tawm nyem rau ntawm kab ntawv rub tawm 32 lossis 64 ntsis version, raws li qhov me me ntawm koj lub computer. Tam sim no koj yuav tsum muaj zip cov ntaub ntawv hauv koj phau ntawv rub tawm (lossis txhua qhov chaw koj xaiv los khaws nws).

Ib zaug ntxiv, Kuv nyiam khaws cov program uas tsis xav tau kev teeb tsa hauv c: / Cov khoos kas, tab sis qhov ntawd yog nyob ntawm yeem. Tsim daim nplaub tshev tshiab rtl_433 hauv c: / Cov Kev Pabcuam (lossis txhua qhov chaw koj xaiv). Ob npaug nias rau zip cov ntaub ntawv thiab luam thiab luam cov ntsiab lus rau daim nplaub tshev tshiab no.

Tua tawm qhov hais kom ua. Txoj kev nrawm tshaj plaws los ua qhov no yog nias lub Windows qhov tseem ceeb thiab R, tom qab ntawd sau cmd hauv lub npov, thiab nyem OK lossis nias Enter.

Ntawm qhov hais kom ua, ntaus cd c: / Programs / rtl_433

(Yog tias koj xaiv nthuav cov ntawv zip rau lwm qhov koj yuav xav tau hloov txoj hauv kev rau daim nplaub tshev raws li.)

Ntaus rtl_433 thiab nias Enter.

Tam sim no cia li tos. Nyob ntawm koj lub zej zog koj yuav tsum tau tos ib pliag, tab sis koj yuav tsum pom cov cuab yeej tawm tuaj. Cia nws khiav txhua hnub los saib seb koj tau txais dab tsi. Kev ntes lub vijtsam yog ob peb ntawm cov ntaub ntawv kuv tau ua thawj zaug.

Los ntawm lub neej ntawd nws tsuas yog qhia cov cim nws lees paub, txawm tias los ntawm ntau yam khoom siv txawm hais tias tsis txhais tau tias txhua. Yog tias nws tsis pom koj lub qhov rooj lossis qee yam khoom siv uas koj xav tias siv 433MHz, sim ntxiv -a lossis -A (tom qab qhov chaw) rau rtl_433 hais kom ua kom tau txais cov khoom nyoos.

Kauj Ruam 9: Mus Ntxiv

Ntawm no, peb tsuas yog khawb qhov saum npoo ntawm SDR tab sis cia siab tias kuv tau whetted koj qab los noj mov. Nov yog ib lossis ob txoj hauv kev coj koj mus ntxiv.

Hloov chaw ntawm lub khoos phis tawj Windows koj tuaj yeem siv ib qho uas khiav Linux.

DragonOS LTS yog Lubuntu Linux nrog tus tswv ntawm SDR daim ntawv thov ua ntej teeb tsa. Rub tawm.iso cov ntaub ntawv thiab siv Rufus los tsim lub cim xeeb bootable los ntawm nws. Koj tuaj yeem khiav nws ntawm txhua lub PC, khau raj ncaj qha los ntawm lub cim xeeb, lossis yog tias koj muaj lub hard disk seem koj tuaj yeem siv lub desktop txuas rau nruab nws tas mus li. Rau txhua ntawm cov cuab yeej teev nyob rau ntawm DragonOS lub vev xaib koj yuav tsum tau nrhiav nws nplooj ntawv nplooj ntawv thiab saib nws ua dab tsi.

Cov duab qhia pom CubicSDR khiav hauv DragonOS. Qhov no zoo ib yam li SDR#.

Xwb, koj tuaj yeem siv Raspberry Pi, txawm tias yog ib qho qub lossis pheej yig heev Pi Zero, txawm tias tom qab tus qauv muaj zog dua yuav ua haujlwm zoo dua. Ntau lub cuab yeej SDR tuaj yeem teeb tsa tau yooj yim siv Synaptic pob tus thawj tswj hwm.

Ib qho yooj yim yog rtl_fm. Qhov no los hauv pob rtl-sdr uas koj tuaj yeem nruab qhov no nrog Synaptic. Qhib Terminal ntu thiab khiav nws nrog cov lus txib xws li:

rtl_fm -f 91300k -M wbfm | aplay -r 32768 -f S16_LE -t raw -c 1

Qhov no yuav tau txais thiab ua lub chaw mloog xov tooj cua FM. (91300k sawv cev 91, 300KHz lossis 91.3MHz - hloov nws mus rau qhov zaus ntawm qhov chaw nres tsheb koj xav tau.) Koj kuj tseem tuaj yeem siv nws los saib xyuas VHF lossis UHF lub xov tooj cua microphone yog tias koj paub nws zaus, lossis tuaj yeem pom nws nrog SDR#.
