RE: Transceiver DC01
Dziękuję za szybką odpowiedź, Postaram się również możliwie szybko uzupełnić opis pozostałej części.
W sprawie brumu mam propozycję abyś spróbował zasilić urządzenie z akumulatora. Z moich doświadczeń wynika, że zasilacz wymaga bardzo dokładnej filtracji. Najlepsze wyniki uzyskiwałem kiedy ostatnim członem zasilacza za stabilizatorem był klasyczny filtr z dławikiem i dwoma kondensatorami po 2-4 tysięcy uF. Oczywiście im większa indukcyjność dławika tym lepiej ale dławik nie może mieć też zbyt dużej oporności aby spadek napięcia nie był za duży. Stosowałem również rozwiązanie kiedy część odbiorcza zasilana była z dodatkowym filtrem a stopnie mocy nadajnika sprzed tego filtra. Dodatkowo, sprawdź czy tranzystor BF245 w pobliżu U13b - ten, do bramki którego prowadzi opornik 470k (+Tx) ma ten opornik dołączony do masy w czasie testowania odbiornika. Tranzystor ten pracuje jako klucz i przy nadawaniu całkowicie blokuje wzmocnienie tego stopnia ale jeśli bramka będzie "wisieć" w powietrzu to może wprowadzać dodatkowe tłumienie ARW lub "łapać" przydźwięk.
Jeśli chodzi o ARW to możesz spróbować zmniejszyć pojemność 20uF w kolektorze BC557 do 10uF zwiększając jednocześnie oporność równoległą 22k do 47k. To powinno podnieść szybkość działania z zachowaniem stałej czasowj układu ARW. Wcześniej jednak proponuję spróbować regulacji ARW za pomocą działającego tam potencjometra 47k i sprawdzenie stanu bramki opisanego wyżej tranzystora.
L.J.
