Mndandanda wa zida zosinthira, ma capacitors ndi resistors
Magetsi; mayendedwe
Magetsi
Setiyi ili ndi chidebe cha batri cha 2 mabatire athyathyathya a 4.5 V lililonse kapena 6 C-size mabatire a 1.5 V iliyonse ( 1″).
Popanda chidebe cha batri 9 V mphamvu paketi (2.6 x 2.1 x 3.2 ″) ingagwiritsidwe ntchito.
Polowetsa ndi kusinthanitsa mabatire ikani choyimira kutsogolo, masulani zomangira zakumbuyo. Chotsani chidebe cha batri mubokosi la batri ndikuyika mabatire awiri athyathyathya kapena 2 C-size mabatire. Mukamagwiritsa ntchito paketi yamagetsi, tsegulani mbale yolumikizira kuchokera ku chidebe cha batri ndikuyilumikiza molunjika ku paketi yamagetsi. Chotengera cha batri sichifunika.
Kukhazikitsa Wosonkhanitsa Zero Signal Current
M'mbuyomu pokhazikitsa sitolo yosonkhanitsa ziro yomwe yakhazikitsidwa pa kutentha kwachipinda choyesera pafupifupi. 1 ora. Lumikizani ammeter (Multavi V, bandi yoyezera 15 mA) kwa wokhometsa kutsogolera kwa V 108 (7) mkuyu. 6. Pafupifupi. Mphindi 1 mutatha kuyatsa. khazikitsani ziro pakali pano kudzera pa chosinthira R 149 mpaka 5 mA ± 0.5 mA pamagetsi opangiratage wa 9 V, onani mkuyu. 3.
Kuyanjanitsa
- Opaleshoni voltagndi 9v.
- Ground chizindikiro jenereta ndi kukhazikitsa.
- Lumikizani cholozera ndi LH kumapeto kwa kuyimba kwa kuyimba.
- Lumikizani mita yotulutsa (Ri
100
) kufanana ndi choyankhulira chomangidwira. 50 mW = 0.5 V zotsatira.
- Sinthani voliyumu kuti ikhale yayikulu, kuwongolera mamvekedwe kukhala malo apakati.
- Pakuwongolera kwa AM-IF gwiritsani ntchito voltage divider, onani mkuyu. 2.
- Kuti mugwirizane ndi FM, gwirizanitsani VTVM (Ri
- Tsatirani masanjidwewo mosamala.
- Bwerezani kuyanjanitsa mpaka palibe kusintha kwina komwe kungapezeke.
Malangizo okwera ndi chingwe choyendetsa
Kuchotsa Chassis
- Chotsani chivundikiro chakumbuyo.
- Chotsani zowongolera.
- Dinani kumtunda kwa mbali ya mbali ya LH (monga mukuwonera kumbuyo) pang'ono kunja ndikuchotsa kuyimba.
- Chotsani wononga imodzi pafupi ndi mlongoti wa telescopic ndipo ina m'munsi mwa bolodi.
- Chotsani chassis kumbuyo kwa owongolera.
Kusinthana kwa Pushbutton Ndodo
- Chotsani chassis.
- Ndi ma tweezers kumasula kutseka pa ndodo ya batani "M", onani mkuyu. 4.
- Pokoka pang'ono m'mbali (pafupifupi 0.04 inchi) pamphuno ya slide yotetezedwa (onani mkuyu 4) kuchotsedwa kwa mabatani 5 kukuchitika (sungani mabatani!)
- Chotsani kankhani batani ndodo ndi m'malo ndi latsopano.
- Mwa kukanikiza mabatani 5 nthawi imodzi, reengage locking.
Kusinthana kwa Drive Cable
- Chotsani chivundikiro chakumbuyo.
- Chotsani kuyimba (onani 4.3).
- Ikani chingwe choyendetsera galimoto monga momwe chikuwonekera mkuyu. 5 (utali pafupifupi 27.6 inchi).

Zosangalatsa
Kuyika kwa malo olumikizirana ndi tebulo lowongolera
Alignment Table
- Chizindikiro cha AM, 400 Hz, 30 ° lo modulated, chiyenera kutulutsa chiŵerengero cha voltage wa 1.0 V. Sinthani voltage osachepera pa mita yotulutsa pogwiritsa ntchito R 147, onani mkuyu. 3.
- Lumikizani coupling coil, pafupifupi. 20 wdg, 2.36 ″
), kupita ku chingwe cha jenereta ndikuyandikira koyilo kuti ipangitse mlongoti. Gwirizanitsani molingana ndi tebulo lolinganiza.
- Kwa ma seti okhala ndi chisonyezo chapadera IF AM 452 kHz = 0.452 MHz.
Udindo wa Malo Oyanikapo
Kusintha ndi kosungidwa!
Kubalana -konso ndi kuchotsa - kuloledwa kokha ndi Chizindikiro cha maulamuliro ogwiritsidwa ntchito
