Tranzistorski 1.8-7.0Mhz Linear
#51
@emiSar zahvaljujem.


U toku testa probao sam i razlicite releje. Gotovo svi nisu mogli da izdrze 400W a da se ne cuje krckanje puckanje. Prilikom predaje aktivira se relej i prebacuje izlazni trafo imedanse na kom se vrsi emisija. Posto to nije dalo rezultata setio sam se da jednostavno koristim kod prijema "ukljucen" relej a tokom predaje iskljucen ali VF je bio toliko jak da se u kalemu indukovala struja dovoljna da aktivira relej  Big Grin  Tu treba Vakumski relej ali on dodje 50e plus sto su potrebni i na low pass filterima sto dodje bas skupo, no za to postoje i druga resenja. Releji su imali (diodu+1nf+10nF+100nF+2,2uF) ali sve to dzaba, doduse situacija se malo popravila dodavanjem 2,2uF. Solidno su se pokazali (100w) ovi finder "beli" ali njihova nozica jedva da je 1mm2 , cak sta vise mislim da je i tanja. Iskreno namerno sam i uzeo ove releje sa Buksnom jer imaju masivan kontakt dobri su za neki ispravljac i neki DC.

Koliko "kvadrata"  (mm2) da se tako izrazim je dovoljno za 500W RF-a, prvenstveno pitam zbog releja.
