RE: uSDX

Rzeczywiście wczoraj uzupełniłem filtr antyaliasingowy przy mikrofonie o drugą cewkę stereofonicznej głowicy magnetofonowej. Częstotliwość filtru poszła wyżej, ponieważ zbocze jest bardziej strome. Będę robił jeszcze próby z dwoma głowicami, czyli z użyciem czterech cewek w filtrze. Filtr ma identyczny schemat jak często stosowane układy w odbiornikach homodynowych. Na razie wszystko w pająku. Jak znajdę optimum to wrzucę to na płytkę mikrofonu i do obudowy.
Tak wygląda mój doświadczalny TRX:

Tak wygląda PA w pająku:

a tak wygląda doświadczalny mikrofon w pająku:

Z PA przy 12V zasilania jest 6W mocy a przy 13,8V jest 9W.

Dziś zmierzyłem IP3 odbiornika.
Wynosi +13dBm. Całkiem nieźle.
Pasmo 3,5MHz odstęp prążków 20kHz
Z pomiarem czułości jest kłopot, bo sygnał wyjściowy nie jest filtrowany i impulsy PWM mają pełną amplitudę. Na ucho jest około 1÷1,5uV.
