RE: Transceiver DC01
Pewne rezerwy wzmocnienia kryją się w obwodach emiterów stopni w.cz. Spróbuj zmniejszyć szeregową rezystancję w dwójnikach RC w obwodzie emiterów tych tranzystorów. Kontroluj jednak czy układ się nie wzbudzi. Pewne możliwości kryją się również w oktawowych filtrach pasmowych. Ze względu na szerokość przenoszonego pasma ich charakterystyka nie musi być optymalna. Można jednak zastosować zamiast tego węższe filtry pasmowe co musi poprawić sprawność nadajnika kosztem możliwości odbioru na każdej częstotliwości. Oczywiście, dodatkowy stopień wzmocnienia zapewni większe wysterowanie łączne ale być może trzeba będzie zmniejszyć wzmocnienie w każdym ze stopni lub w stopniu o największym wzmocnieniu aby zapewnić stabilność pracy.
Z innej strony patrząc, to DC01 jest w założeniach transceiverem QRP więc można powiedzieć, że je spełnia ;-)
