RE: US5MSQ - transceiver

Polecam swój zmodyfikowany schemat wzmacniacza m.cz. na TDA2003. Całkowite zero szumów nawet na najlepszych słuchawkach, idealnie czyste brzmienie sygnału.
Uzyskane jest to poprzez bardzo silne sprzężenie zwrotne, co pociąga za sobą znaczne obniżenie wzmocnienia. W związku z tym kompletny układ powinien jeszcze zawierać oprócz TDA2003 jeden wzmacniacz operacyjny z ustawianym wzmocnieniem.
Schemat można znaleźć w wielu miejscach, między innymi tu:

Wzmacniacz polecam szczególnie tym kolegom, którzy podczas łączności będą używać słuchawek i nie chcą słuchać szumów na mocno skręconym potencjometrze.
