RE: Transceiver DC01

Witam,
To mikrofonowanie występuje tylko w obrębie układów U14-U15, badam przy wyjętym U13. Poprawiłem wszystkie luty, zwłaszcza te związane z masą. Mikrofonowanie występuje nadal, nie ma żadnych zmian. Zaczynam podejrzewać jakiś defekt PCB. Ciekaw jestem czy u kolegów, którzy właśnie budują DC01 też to wystąpi. Temat ten na razie zostawiłem i zacząłem modyfikować ARW, m.in. zmniejszyłem kondensator ze 100uF na 50uF w stałej czasowej 220k-100uF, co przyśpieszyło czas zadziałania ARW na tyle, że nie jest już dokuczliwy "podskok" sygnału w pierwszej sylabie dla silniejszej stacji. Ale chcę modyfikacje ARW prowadzić dalej, na tyle ile jest to możliwe w "gęstwinie" elementów na PCB. Powoli też zbliżam się do końca montażu, uruchomiłem częściowo wzmacniacz TX. W przerwach prac słucham wieczorami na 160 i 80 metrach i delektuję się jakością odbioru. Przygotowuję Pa Tajfun wg Roberta SP3RAF, co powinno dawać na wyjściu ok 50 watów mocy. Może już niebawem będzie pierwsze QSO.
