HF linear
#1
U neko dogledno vreme razmisljam o linearu koji bi bio negde 300-400w. Prvo cu nabaviti nekli Behringer XLR mikrofon, potom neki na primer EMU Creative zvucnu karticu sa fantomskim napajanjem 48v e zatim sledi gradnja lineara.

Razmisljam o 4xGU-50 nasao sam na netu seme. Nedavno sam uradio mali linear na test plocici za 80m koji ima oko 80W to je radilo i vise nego dobro imao sam cast da par veceri razgovaram na KT-u sa G. Borom "YU1OXB". Linear je bio prikljucen na mom SDR-u. Bio je sa dva feta IRFP140n Malo ogranicavajuc faktor je 10Mhz do koji tranzistori rade za RF, a za elektronske cevi sam se odlucio zbog rada na visim bandovima i zbog samih karakteristika da nece bas lako pregoreti kao tranzistori.

Ima nekih stvari koje mi nisu jasne oko cevi posto bi to bio prvi dodir sa elektronskim cevima, naravno jako je opasno ako stvarno dodirnem anodni napon Smile

Imam puno nejasnoca prva je koju semu da odaberem, vise sema sam nasao sa PL519 , e sada voleo bih vise GU-50


evo sa pl 519

evo sa gu50 ali 6kom , ovo mi je ipak previse snage ali mozda da "ukradem" nesto od ovoga? Naravno displej mi bas i ne treba. Na dnu je PDF sema

Isto mi je nejasno oko napajanja kakav trafo motati ako mi treba 1200v DC da li da trafo bude 1200v/1.4 dakle oko 850V AC napona i negde racunam 500mA za 4 kom.


Glavna mi je tema sta odabradi PL519 ili GU50 da bih mogao da nabavljam polako ove stvarcice

To cu pobudjivati najcesce sa 5W "SDR" tako da on nece imati bas 400W pa da ima i 100-150w dosta je, nego neka ima rezerve ako hocu koristiti stanicu. Uzgred ako neko ima neka resenja kao i objasnjenja evo teme koju mozda nekada nekom i zatreba.
