RE: Transceiver DC01
Cieszę się, że odkryłeś zalety odbiornika DC z mieszaczem Tayloe. Zabierając się za układ ARW najpierw sprawdź czy nie masz za dużego wzmocnienia w torze co się objawi tendencjami do wzbudzania się wzmacniacza m.cz. jeśli zrobisz odbiór nieco głośniejszy. Generalnie biorąc tor odbiornika ma nadmiar wzmocnienia więc jeśli się okaże, że można wykorzystać tylko początkowy zakres regulacji potencjometru m.cz. to spróbuj zmniejszyć dwukrotnie R50 ze 100k na 47k a jak to będzie dobry ruch to zwiększ też dwukrotnie C28 do ok. 300pF. Dopiero jak ustalisz ostatecznie wzmocnienie zajmij się regulacją progu ARW. Najlepiej robić to z kalibrowanym napięciem wejściowym odpowiadającym odpowiedniej wartości S. Ustalenie poziomu reakcji ARW jest o tyle ważne, że dopiero później można zająć się wskaźnikiem S. Każda późniejsza zmiana w torze ARW zapewne wpłynie na działanie wskaźnika S więc kolejność powinna być właśnie taka: najpierw ARW a później wskaźnik S. Wzmacniacz wskaźnika S ma dwa regulatory oraz oporniki Rx iRy, które należy dobrać do wskaźnika. Na początek można zamiast tych oporników wstawić rezystor nastawny w zależności od oporności miernika o wartości 4.7k a nawet 1k. Można również zastosować zamiast Rx i Ry kombinację diody zenera i opornika po ustaleniu właściwego poziomu napięcia odniesienia.
